Masters of Carcosa - Session 16

by Ramanan Sivaranjan on December 16, 2025

Tagged: mastersofcarcosa carcosa

Some important discoveries this session. The Rainbow Connection finally discover the lair of the Jale Slavers. They had first learned of it after rescuing some slaves in the wilderness. They would begin to plot its downfall starting now.

They meet my Carcosa take on Trap-Jaw. I had written up a Carcosa style He-Man encounters, though I didn’t end up using too many in my game: 16 Encounters on Carcosa & [16 More Encounters on Carcosa][h2]. Master’s of the Universe was meant to be core to the whole game, and I tried to inject littles bits and pieces of that world when I could. I wrote these encounters after reading Richard’s [How Brightly Coloured Should Carcosa Be][color]. This post about Carcosa and Masters of the Universe was one of the biggest inspirations for my game. It’s what got me thinking about Carcosa in a completely different way.

They also discovered that the Castle of Decline was empty. The Bone Men from that town had said they would join them in Invak many sessions ago, but never made it. The party would learn what happened to them for a few more sessions. (Half travelled south to Snake-Men ruins, others were captured by Slavers on route to Invak.)

Finally the players find the Orange Citadel’s former “God”, the Frog Spawn Llothali. They killed the creature so hard I would end up having lots of discussions with them about whether the laser guns in the game were too over powered. Probably, but we never ended up changing any of the rules.

The players had their home base in Invak, and had a strong relationship with the merchant town to the south, Jahar. At this point in the campaign they wanted to try and unify the region around the common aim of dealing with the slavers. There was a lot of travel between the two towns session, as they tried to negotiate an agreement. This was the session the Space Alien Strike Force finally made an appearance. They had been hinted at over the previous session, and were an entry on my random encounter table for some time. They were looking for whomever desecrated their tomb and stole the armour of their hero. Bad luck for the players: Gus’s character was wondering around in that armour. Had been since they found it. Hilarity ensues.

The players also reconnected with the women who escorted them to Invak at the start of the campaign, Queen of Autumn. Another random encounter roll? I don’t remember anymore.

Masters of Carcosa - Session 14

dude getting blasted

As you’ll see in the comments, I had been reading Blood Meridian, and the book and its mood started seeping into the game. I wrote about this a few years ago: A Carcosan Western. The game was meant to be light-hearted Masters of the Universe themed game, and while there was a fair bit of that, the game was probably more cowboys than He-Man. (That said, the Staff of Avion the players find this session is from Masters of the Universe.) The players were wandering the wastelands, having shootouts with bandits.

The dead man they find on the road was meant to be a clue something was amiss at the castle, but maybe not enough of a clue. The Snake Men ruins were another important site in the game the players would ignore. Kheret ils Nu’s Reliquary, which I wrote for the Trophy Gold megadungeon, borrows ideas from this campaign and these ruins my players never explored. The Snake Men would end up freed by the Dominant Reflection. They would restart their war with the Old Ones, so nominally aligned with the players, except to the Snake Men the players were just reagents for spells.

My rules for getting lost seemed to only come up when the party would leave their home base. They were constantly getting lost right next to their home. A little silly, but I kept with it because I thought it was funny.

Masters of Carcosa - Session 13

aliens

This session the players explored the rest of the Space Alien outpost. When the returned I had re-stocked the space differently, because it had been captured. The rooms that they had not explored previously were sealed, so that area was unchanged.

This session feels like some stereotype of an OSR game. The party wakes up all the Space Aliens that manned the outpost, who were in cryropods. Nick decided the best course of action was to knock one out while he was still disoriented, and run away with him. Maybe they were unsure what the deal would be with these particular aliens, and wanted to chat with one of them alone? This Space Alien ended up living in Invak, convinced he had been saved by the party and that all his friends were dead.

The rest of the session is typical Carcosa hijinks. They stumble up on the Frog-God Llothali that they had let loose in the wilderness when they freed the Orange Man citadel.

Spotty attendance after the last game because I moved the session a week, and didn’t create a new event. Once again, my biggest advice for running a long running campaign is playing on a consistent schedule. People will often say this game or that game have the mechanics required for long term play. Fuck that, the only mechanics you need are a calendar and actually showing up.

Masters of Carcosa - Session 12

Bone Man

My Carcosa-style recap of this session was as follows:

The Bone Man sorcerer, The Dominant Reflection (AC 16, MV 90’, HD 4, Chaotic) has taken over the abandoned Space Alien outpost, along with a sizeable group of Bone Men cultists. They worship the long dead Snake Men.

I had been teasing Bone Men cultists operating between the party’s home town of Invak, and the merchant town to the South, Jahar, for a few sessions. The Space Alien outpost was between the two towns, and was also home to secret village of Bone Men. It was time to finally scope out what was going on!

I had fun seeing this long running thread from [the start of the game][s1] finally lead somewhere. As I have mentioned earlier, the Bone Man the party freed from a cell in the very first session was actually a dirt bag sorcerer, the Dominant Reflection, imprisoned by the rest of Bone Men that lived in the outpost. While the players were wandering Carcosa, he was gathering up a crew of cultists, who then took over the outpost, making it their base of operation.

The players some how managed to steam roll their way through the outpost, building up a posse as they freed captives. The session concluded with them saving the town. One of the more He-Man sessions in the game. In the commotion the Dominant Reflection escaped! There is chatter in the comments about what happened off camera, whether it was cheesy or not to let the character escape. I thought not, and the players agreed.

The players convince the town’s leader to come back with them to Invak in the post game discussion. We would sometimes play out things like that in post game chat between sessions.

This would end up being the midpoint of the campaign, though I didn’t know it at the time. Kind of fitting we looped back to where we started.

Masters of Carcosa - Session 11

Tagged: carcosa mastersofcarcosa

This is the first session Chris P joined the fight. There were two Chris’s on G+ that were consummate players. Like Eric, they were almost always down to play whenever you would post a game. Players like that make running a poorly organized campaign work.

When I would share invites on G+ for the Masters of Carcosa sessions I would include rumours and news the players had learned. There was also a post on my G+ community for the game where I would keep all the loose threads up to date. For this session the players knew the following:

  • Trade between Invak and Jahar presumably remains on hiatus for now while Jahar’s merchants waits for this cult to move on or be replaced.
  • The merchants will travel East to the Citadel of Brown Men known as Lessel.
  • Deep One sightings at the Lake to the South.

During the session they would learn more about the deep ones, who apparently had emerald belts. (The deep ones in this game were effectively Mer-Man from Masters of the Universe.) This was the rumour the players decided to follow, resulting in a very straight forward session compared to some of the others: kill some cultists, free some captives, find some treasure.

The party finally learned some more rituals, not that it really mattered. The rituals didn’t really match the vibe of the game, even though Chris’s character was a real dirt bag sorcerer. He was constantly trying to learn and find more, and I basically didn’t really want them in my game so was kind of a real dick when it came to having them show up in play. For the most part playing a Sorcerer was just the hard-mode version of playing a Fighter. The classes were the same, but Sorcerers had harder XP requirements.

The next session the players will return to the “abandoned” Space Alien outpost that kicked off the campaign. It’s kind of neat that it happened to happen at what would be the midpoint of the campaign.

My Carcosa-style recap for the session is quite terse, because the session itself was very to the point.


Players:

Recap:

Rituals:

Summon Amphibious Ones - This eleven-hour ritual can be completed only on a fog-shrouded night. The Sorcerer must obtain the root of potency found only in ruined apothecaries of the Snake-Men. The sacrifice is a virgin White girl. As her life leaves her body, 10–100 of the Amphibious Ones will coalesce out of the mists.

The Blasphemous Sacrifice (to Bind Amphibious Ones) - This ritual cannot be performed on its own, but only as an adjunct to the SUMMON THE AMPHIBIOUS ONES ritual. It adds an hour to the time required to complete the ritual (thus twelve hours total). The sacrifice is further subjected to an hour of unspeakable tortures before being slain. At the end of the rituals, the Sorcerer will have complete control over the horde of Amphibious Ones for 24 hours.

The Call of Cthulhu (to Summon Cthulhu) - This 24 hour ritual must be cast while waist deep in the polluted waters of Carcosa. Once the ritual chanting and genuflection begins, the sorcerer must drown a Purple Men at the end of each hour of the ritual. All the victims must be a willing sacrifices to the Great Old One Cthulhu. When the life leaves the last of the Purple Men, Cthulhu will rise up from the waters.

I remember this session really well, because it was another weird one. Only Dion and Willie could make it, and they didn’t want to do anything risky. The players travelled with the merchants on their trip South, stopping in the village of Glom. There they met affable Carcosans and got totally wasted. The description for the settlement in the hex is as follows: Village of 310 Ulfire Men ruled by “the Unapproachable Radiance,” a neutral 6th-level Sorcerer. A lot of the Carcosa book is villages like this. That somehow transformed into what is described in the recap below. I am quite certain that going into this session I thought the players would return to the cavern they had been exploring, and so when they didn’t I had to spin something out from my most meagre of notes. Besides the description in the Carcosa book, the only thing I knew about this town was its name, which I had given it when drawing the initial region map for the campaign. In my notes I had something about Mer-Man cultists worshiping Cthulhu by the lake. I’m pretty sure I came up with the idea of evil Cthulhu lake water as a type of booze, and then just extrapolated everything else from that. Sometimes that’s what you gotta do.

This is the first session Eric missed! There was a mixup because I kept on rescheduling. This is why you need to be consistent when you’re running games!

In my Carcosa-style recap for the session, I’m much more explicit about what’s going on in the town.

Masters of Carcosa - Session 9

Carcosa T-Rex

The players had found a Space Alien compass in an earlier session and decided to see where it would lead them. I had decided it would lead them towards the tomb of a dead Space Alien hero. A nearby hex was described in the book like so:

In a pure white chamber is the perfectly preserved corpse of a Space Alien wearing a suit of reflective armor that protects against the following types of weapons: microwave, yellow laser, dysprosium, polonium, nickel, neptunium, cesium, strontium, radon, aluminum, boron, mercury, thulium, protactinium, niobium, and helium.

In my Carcosa style recap of the session, one of my fictional alternative endings to the session was as follows:

8 Space Aliens (AC 12, MV 120’, HD 3), part of an elite combat squad, pursue a group of Carcosan who have defiled one of their tombs through the badlands. They are armed with laser rifles.

They were first mentioned in the session 7 recap, and I likely added them as an entry on the encounter table for the region shortly after. The players would meet them a few sessions later. As I mentioned earlier, I would sometimes use the recaps as a way to share rumours, and also share news about the off camera world with the players. In the session 8 recap I shared that the Bone Men cultists were taking people back to an Abandoned Space Alien Outpost. The players would eventually return there, but I don’t think it was because of the mention in that recap. This is probably too subtle a way to share what’s going on, but it was a fun all the same.

I also used the other entry from Hex 1113 this session, having the mutant T-Rex show up.

There are no settlements in this hex because of the mutant tyrannosaurus (AC 15, MV 150 , HD 15, Neutral, 30 aura of radioactivity, bulging eyes, transparent skin) that slays anything in its vicinity.

The entries in Carcosa are quite terse, but sometimes that’s all you need for something to be memorable. I got quite used to spinning out whole sessions from a few sentences, both in my own notes and from the book.

… the leader of Invak would pay for the heads of Jale Slavers, and so the game because all about hunting the slavers and chopping of their heads. Blood Meridian, but in Carcosa. (Except the party would actually kill slavers, not any old person.)

Wait, I lied. This session the party does end up killing people and taking them back to Invak to collect their reward. Bad PR for OSR players everywhere.

Were these Bone Men slavers? No, I’m pretty sure they were cultists working for The Dominant Reflection. If you have been following along, in the very first session the players freed a Bone Man they found imprisoned in the Abandoned Space Alien Outpost. He disappeared into the wilderness, but that wasn’t the end of his story. At this point the players had not encountered him or his followers again, but that was soon to change.

The party also some how manage to turn the death of two hirelings they recruited in town into some positive PR, paying for their funerals. Jahar initially had a negative disposition to outsiders, but the group would slowly change that over the course of the campaign.

The main goal for the session was to pilfer Alien technology from the campsite of the lost Space Aliens they had rescued recently. This resulted—once again—in a battle with insane Mi-Go. How many times would I have the players fight Mi-Go? Several: I always listen to the results of the dice!

The party finally visits the merchant town to the South, Brown Man village of Jahar. These merchants were the ones who escorted the players up to Invak in the first session, when the party encountered them on the road. Because the party had gained some notoriety in the region they were able to wander and meet with the people of the town. I’m quite certain I ran this sort of things using reaction rolls. I tracked the groups renown, which I would sometimes use to modify results up or down, but not in a way that I was particularly consistent about.

You can see that once again I was laying it out pretty thick when it came to reasons to explore the Putrescent Pits of the Ameboid Gods. Don’t worry, the players wouldn’t take the bait.

Being worried about the game being boring was a common theme it seems.

That review ended up focusing a lot on how I prepared to start the game, but didn’t talk much about actually run the game.

map of caverns

The session began with exploration and learning more about the world. This was the first time the party got lost in the wilderness, an important part of the game. My travel rules worked. The party found more caves to explore in the future, and learned of a second citadel that purportedly held a tomb of vile sorceress magic—the best kind. The party would refuse to seek it out for the remainder of the game, of course. The later half of the session was spent getting high with some stoner Carcosans. Dion joined the game this session, and was a fixture in the campaign for a long time to come, playing Ulfire Sorcerer Asha-Rea. His character used the distraction of everyone getting high off their ass to steal some Jale Lotuses to sell later. A quiet session, but they can’t all be loud.

Masters of Carcosa - Session 3

Map of my future megadungeon

The party had been told rumours that there were healers to the south that could heal Gus’s character of his terrible mutations. (You may recall that was his first character’s fate in our first session of the game.) The party ignored those rumours last session, but decided to pursue them this time. Bryan’s character came out of my random generator with a tattooed map on his skin: a map to the mega-dungeon I had imagined I would run, whose name appears in Hex 1109 of Carcosa: On the northern slopes of the mounds are the yawning pits that lead down to the infamous and deadly Putrescent Pits of the Amoeboid Gods.

I would occasionally seed more rumours in the alternate future restocking tables I would create after each session, as part of my recaps. For example, in the recap for this session I wanted to let the players know that another group as aware of the Putrescent Pits of the Amoeboid Gods and would explore it even if they did not:

A caravan makes its way North. The men and women ride lumbering lizards and have several days worth of supplies. They have a map leading to the Putrescent Pits of the Amoeboid Gods.

When I would post the invites to the games on Google+ I would try and include these open threads and rumours so the players had some rough ideas for things they could do. There was no overarching “plot” for the campaign, I was curious where the players would take play. It turned out, not to the Putrescent Pits of the Amoeboid Gods, so I’m glad I only ever drafted the first level.

This session the party learned a little more about the Jale Slavers, stumbling upon some escaped slaves. I created specific encounter tables for the rough regions I had imagined the hexes could be grouped into. Because this area was home to the Jale Slavers, there were entries tied to them. The first session the players had rolled to encounter some slavers after after they had sold off their slaves. This session the rolled and encountered some escaped slaves. They wouldn’t find the slaver’s base till the tail end of the campaign.

The men on standing upon the giant plinths come from the Carcosa book. A couple sentences describe the scene, which I extrapolated from. I love the short pithy hex descriptions of Carcosa. From these men Gus learned his character could be cured by heading far to the North. I had imagined this might lead the characters out of this region, but Gus didn’t even like the character they were trying to cure, so that thread was left alone.

The party discovered The Castle of Decline, home to a group of sad-sack Bone Men. One of the first groups outside of Invak the party would end up befriending. If I recall correctly, they eventually convince the Bone Men to abandon their home and join them in Invak. (Easy enough, since their home sucked.)

The session ended with the briefest exploration of the Putrescent Pits of the Amoeboid Gods. They might have explored a handful of rooms before us having to end the session. They would never return!

At the time I thought the session might have been boring, but reading the recap and thinking back on everything the players managed to do, I have no idea why I thought that was the case. There is some more logistics around who will run something next. I realize now it was Bryan and I trading turns running because Brendan and Nick wanted a break. (Brendan was running his dungeon & rule set The Final Castle, which remains unpublished to this day!) Chris was a new player, who would join our games for a little while, on and off.

My carcosa hex map

When I was running my Carcosa campaign, I would post session recaps on my blog in the form of hex descriptions written as if they came straight from the book. Each session had additional descriptions for each hex the characters explored, and I also included a random ‘restocking’ table. Three of the entries in the table would present alternative endings to the session the players just played, with the forth being the true ending. This was all very cute, but I also kept traditional notes of what happened so myself and the players could refer back to them later. These were posted to G+, where you can still read them today.

Oh wait.

I’ve been meaning to repost these session reports for a while. Nick downloaded my Carcosa community before G+ imploded, and the export has been sitting on my computer for ages as XML & JSON I never had the time to turn into Markdown. But now computers can do a so-so job programming for you, so I have text that’s pretty close to cleaned up Markdown. I’ll take it.

This is the first session of my Carcosa crossed with He-Man campaign. I ran it for a little over a year, playing every other week, give or take. The rules were OD&D, and we all were figuring out how to run a hex crawl as we went. It was a lot of fun. Perhaps the most fun I’ve had running a game?

This was my first time DM’ing since I was a teenager. I was certainly nervous. Brendan took a break from running Pahvelorn, and I took over the spot every other week. (I think Nick might have been running the other week.) Pahvelorn was certainly a hard act to follow. Brendan’s megadungeon campaign was incredible, and really inspired how I ran this campaign.

Carcosa is a hex crawl, and my expectation was players would wander the wilderness session to session. This happened for the most part, but party didn’t stray too far from their home base. The party were called the Rainbow Connection, a travelling acting troupe. (This was rolled up using my crowdsourced “why are we together” table.) During the first session the players explored a dungeon I created, an abandoned space alien outpost. They released one of the main antagonists of the game, a Bone-Man sorcerer. He would get more and more powerful while they were distracted by the faction they would come to hate the most, the dirtbag Jale Slavers.

Review: Carcosa Review Reprise

by Ramanan Sivaranjan on March 28, 2015

Tagged: carcosa lotfp osr mastersofcarcosa

You should do a post … having DMed several sessions, about what you find Carcosa brings to the table and what you’ve done to make it “yours?” — Cole Long

I write reviews for gaming books I never actually use to game, which feels kind of dumb but what can you do? Now with Carcosa I can actually comment on the book with insight from using it to run a D&D campaign.

I’ve ran 7 games of Original D&D game set in Carcosa. The original idea for the game was to mix in elements from Masters of the Universe into the Carcosa settings, but that hasn’t quite happened just yet. I’m really not familiar with most of the literary references that inspired Carcosa, which makes running the game “interesting”.

I wanted my campaign to start in a Lawful settlement. I had catalogued all the settlements in the game as a byproduct of working on my Random Carcosa web application. The highest level Lawful leader in Carcosa is 11th level and can be found in Hex 1011, along with a crazy robot.

Village of 270 Bone Men ruled by “the Swift and Silent Beginning,” a lawful 11th-level Fighter.

The unwary may fall prey to a deranged, spherical robot (AC 18, MV 180′, hp 25) with treads and retractable appendages, nets, self-repair, infrared, and long-distance vision. It will seek to abduct stragglers and take them to a small, hidden outpost to be shackled in close proximity to radioactive waste. Each hour spent thus requires a successful saving throw to avoid mutation.

I printed out some hex graph paper and drew the region around this hex, marking down the settlements and their allegiances to the battle between Law and Chaos. The official Carcosa map in the book is missing this information, which would have made it about a million times handier. Zak Smith drew in his Carcosa book, but I just can’t bring myself to do that.

There are slavers nearby in Hex [REDACTED] terrorizing the region, and so I made them the main threat in the game. I decided the town of Invak would offer refuge to former slaves. This would explain why a party of PCs would likely include people from the various races of Carcosa. Chaotic villages close to the slavers were likely to supporters, as were Neutral villages nearby. Villages closer to Invak would be against slaving. Invak would be a bastion of egalitarian and progressive thought, in another wise terrible world. The town to the South of Invak became a trading hub, liking Invak with a few other towns near by. In this way I fleshed out the relationships between the various villages in the area.

I answered Jeff Rient’s 20 Quick Questions about your Campaign, which helped me think more about what my game would be like. From an older blog post about Carcosa I knew “the Icon of Judgment” was the strongest sorcerer in the world. I made some rough notes about what his deal might be, but thus far it hasn’t really come up in play: mostly because I haven’t brought him up at all. The castle of Chaotic Orange Men North of Invak became a crazy cult running bizarre gladiatorial games.

I drew a map of the hidden outpost. It seemed like a good dungeon to begin the game with. Players would start shackled in the radioactive wastes. I introduced a small group of Bone Men, who were hiding out inside this outpost. They had imprisoned one of their members for [REDACTED]. The robot would only be ‘active’ at night, and would only travel through the wilderness, so the players wouldn’t have to worry about it unless they specifically tried to instigate a fight with it. There were also lasers, spawn, and other things that felt like Carcosa.

This was enough to start playing. I ran a session with Gus and Eric, two of the regular players from my Monday night D&D group, and things continued from there. I am constantly underprepared for each session we play, but things usually work out—for the most part.

Eero Tuovinen has done an amazing job with the layout of Carcosa. Carcosa is a well laid out book that works well at the table. I flip through it often looking up monsters, hex descriptions, and the like. Most everything is easy to find, and more importantly easy to read. McKinney has a very terse and direct way of writing that I like. He manages to be evocative without wasting too many words—usually.

In terms of helping you build a campaign, Carcosa brings barely any information to the table. The book succeeds in selling the idea of Carcosa, without really telling you that much about it. Are all the races identical besides their colour? Do they all share the exact same culture? Are their multiple languages in the world? What are the towns and villages like? What do people eat? What’s a GP in Carcosa? There are so many questions about the world that are unanswered. Explicit relationships between hexes are few and far between. This encourages the sort of brainstorming I did to get things going, but is also one of the big criticisms of the book: it all feels so random. I would have loved for some discussion from McKinney on how he explicitly organized and ran his game.

The big win for Carcosa is that I never feel like i’m doing it wrong. I never have to look something up so-and-so important NPC, or double check the date such-and-such event took place. Carcosa is a loose framework for building your own Carcosa. I’m not sure I have done that great a job of build my own Carcosa, but i’m hoping that I am not too far off.

11 Bone Lotus Potion Drinking this translucent potion will render the imbiber gaseous, allowing them to pass through anything that isn’t air-tight, and making them impervious to most attacks. 1d10 x 100 GP
12 Purple Lotus Powder When mixed with other slow burning herbs and smoked this powder acts as a depressant, relaxing the mind and making its user completely open to suggestion for 1-4 hours. 1d6 x 50 GP
13 Orange Lotus Potion Produced using the sweet nectar found within the buds of the Orange Desert Lotus, this potion grants super-human strength to those who drink it. Characters do an additional dice of damage when attacking with melee weapons. This effect lasts dCarcosa turns. 2d4 x 100 GP
14 Ulfire Lotus Poultice Applying this poultice takes one turn, and leaves the characters skin feeling dry and rough. Characters gain an addition +2 to their AC and to their saving throws where applicable. This effect lasts 9-12 hours. 2d6 x 100 GP
15 Ulfire Lotus Potion This potion is a powerful anti-poison, nullifying the effects of any lotus based poison or powder. 1d6 x 100 GP
16 Brown Lotus Poison Typically applied to the tips of arrows, this poison instantly kills those who fail their Save vs. Poison. 1d4 x 500 GP
17 Dolm Lotus Potion The character feels a quickening of their body and mind as this potion takes effect. Characters double their movement rate, and start combat at the top of the initiative order. This effect lasts 1d6 rounds. 1d4 x 500 GP
18 Dolm Lotus Powder When smoked as a powder this lotus produces an unnatural lethargy (and euphoria) in its user. Characters regain dCarcosa hit points, but are unable to do anything besides lay around for 1d6 turns. 1d4 x 50 GP
19 Red Lotus Poultice The restorative power of the rare Red Desert Lotus is without equal. Rubbing this poultice over a dead character’s body will restore them to life, assuming they fail a Save vs. Poison. 2d6 x 1000 GP
20 Red Lotus Potion This potion fills the drinker with supernatural vigour that lasts 9-12 hours. If killed while under the effects of the drug the character will instantly return to life with dCarcosa hit points, as their body absorbs all the red lotus in its system. (This effect can only occur once.) 2d6 x 1000 GP

Each usage of a potion or poultice produced by a desert lotus apothecary has a 1 in 20 chance of producing a great feeling of a addiction in the user. All powders have a 1 in 6 chances of being addictive. Players who are currently addicted to what they have just ingested must take another dose (which grants additional positive effect) or be at a -1 on all rolls for the session. Using a desert lotus product more than once a session increases the chance of addiction by 1, 2, 4, 8, etc.

Apothecaries that work with the desert lotus will generally have a random selection for sale week to week, prices varying based on the availability of flowers.

Why Are We Together

by Ramanan Sivaranjan on February 14, 2015

Tagged: carcosa lotfp osr homebrew mastersofcarcosa

The default setting for Carcosa is full of xenophobia. I wanted a list of reasons why a group of adventures of various races might be adventuring together. I started writing one, but got stuck fairly quickly. So, I asked my friends to help out. The good entries below were all written by people other than myself. They call that Gygaxian Democracy.

Why are we together?

  1. Awoken from a lotus induced stupor you have fled from a sorcerer. I’m sure they want you back.
  2. Escaped from Slavers! One day you will have your revenge on those bastards—unless they get you first.
  3. Members of a traveling troupe of actors. You know one play, which you tweak based on your audience to play up on the local prejudices.
  4. Members of a janissary regiment, put together by long gone—perhaps?—Alien overlords.
  5. After years of wandering with your herd the symbiotic fronds were yanked out from the backs of your heads. Who knows how many years you lived as root heads.
  6. Returned to Carcosa after being experimented on by the Space Aliens. Hopefully they don’t come looking for you again.
  7. Cultists! (Must share a common alignment.)
  8. Foundlings raised by Lawful spawn hunting illuminati.
  9. The wrong coloured children of an otherwise homogenous village. Did they treat you well?
  10. Refugees who have fled a natural disaster. Famine? War? God damn Aliens with laser guns?
  11. Kidnapped orphans raised deep in the desert by a mad, but kindly, old couple.
  12. Psychically summoned to a crashed space ship. You have no memory of the recent few months.
  13. Members of a diseased community of outcasts. Everyone shares a common (mostly harmless) mutation.
  14. Emerged from a sorcerer’s birthing vats deep within an abandoned complex. (Thousands of other pods full of replacement PCs available as well.)
  15. Once from a religious community, where all members wore body obscuring clothes and lived as equals without colour based caste. After the sorcerer’s troops/raiders/slavers/shaggoths came that dream, and the obscuring robes and windings, have been cast aside.
  16. A bad medicine show went through some villages a while back selling poisonous mutation causing ‘snake squeezings’. The adventurers are relatives of the slain, banded together to hunt down huckster and deliver ‘justice’.
  17. All that remains of the local criminal underworld, driven out by an unspeakably violent new boss or spawn inquisitors.
  18. Each character bears the same tattoo, which causes horror amongst village elders Carcosa wide. (The characters have no memory of when or how tattoo appeared.)
  19. The former retainers of a group of strangely coloured people who spoke a weird language and claimed to be from another world called Dirt (or Earth or something like that). The original adventurers are all dead, but retainers continue to adventure together. Some continue to search for a portal to this world of Dirt, because there are no shoggoths there.
  20. You each have vague memories of a past life as a White Man sorcerer, until you performed some ritual that split you into different facets of your core personality.

In the game I am running now, the players rolled a 3 when starting the campaign. So, they are all members of the acting troupe The Rainbow Connection. Their back story has been far more fun than I had thought it would be.

Thanks to Stuart P, Brendan S, Evan W, Gus L, and David R and everyone else for their ideas and suggestions.

Ascending AC for OD&D

by Ramanan Sivaranjan on December 23, 2014

Tagged: mastersofcarcosa odnd

I have been using ascending AC for my OD&D Carcosa game. Players roll a d20 to hit, add their attack bonus, and try and score higher than their opponent’s AC. An unarmoured combatant has an ascending AC of 10; plate armour and a shield confers an AC of 17. It’s a much simpler system for adjudicating combat in my opinion. People know if they have hit or not without having to look at a table, and the arithmetic is all quite straight forward.

What follows are the tables from the first OD&D book MEN & MAGIC redone so they work with ascending AC. (I am certain I am not the first person to do this, but there wasn’t an obvious hit when I looked on Google.)

The attack bonus progression for the Fighters is:

Level Attack Bonus
1–3 +0
4–6 +2
7–9 +5
10–12 +7
13–15 +9
16+ +12

For Clerics:

Level Attack Bonus
1–4 +0
5–8 +2
9–12 +5
13–16 +7
17+ +9

And for Magic-Users:

Level Attack Bonus
1–5 +0
6–10 +2
11–15 +5
16+ +7

Monsters use the following table.

HD Attack Bonus
up to 1 +0
up to 2 +1
up to 3 +2
up to 4 +4
up to 6 +5
up to 8 +6
up to 10 +8
11+ +10

The tables are simple enough to make. In a descending AC system a first level characters needs to roll a 10 to hit AC 9 (an unarmoured person), which we determine by looking at the attack table in MEN & MAGIC. To hit that same character who has an ascending AC of 10 by rolling a 10 (or more) implies a 1st level character has no attack bonus. A 4th level fighter only needs an 8 to hit that same character, so their attack bonus is +2.

Eating Sorcerer Brains

by Ramanan Sivaranjan on December 11, 2014

Tagged: odnd carcosa homebrew mastersofcarcosa

Sorcerer’s in Carcosa are creepy and despicable, and the magic of the setting is totally horrific. I had originally assumed no one would want to play a sorcerer in the game I was running because they are quite villainous. Since everyone is using my random character generator to make characters there is a 20% chance of anyone playing ending up with a sorcerer. There are currently two in my game.

It only took two sessions before one of my players turned to cannibalism. The goal was to learn some sorcerous rituals, and eating the brain of your rival sorcerer seemed like as good a way as any.

Running Carcosa has been fun and lighthearted thus far—seriously.


Eating Sorcerer Brains

Sorcerers may attempt to learn new sorcerous knowledge by devouring the brains of other sorcerers. This isn’t an ideal way to learn ritual magic, but sorcerers are often quite secretive about their sorcery, and reticent when it comes to sharing what they have learned.

The player should roll under their constitution score. Success indicates they have learned some new ritual(s). The number you succeed by indicates how many rituals the player learns, which are selected randomly from those the dead sorcerer knew. Those who fail this check should roll on the I shouldn’t have ate that brain … table. Brains need to be harvested and eaten as quickly after the death of the sorcerer as possible: impose a penalty of 1 to the roll for each minute that passes after the death of the sorcerer.

Players who are not playing sorcerers, but decide to eat a sorcerer’s brain, should just go ahead and roll on the I shouldn’t have ate that brain … table.

I Shouldn’t have Ate that Brain

d8 Effect
1 Maybe you ate it wrong? No ill effects, but you have learned nothing.
2 Your stomach feels terrible. Moments later you are on your knees retching. The character is completely incapacitated for one turn, and making a fair amount of noise.
3 That’s just not sitting right: you dry heave for one round and feel woozy for the rest of the day. The character is at -1 to all attack rolls and dexterity checks.
4 The brain acts as a mild hallucinogen. The character is has a 1d6 penalty to all Wisdom and Intelligence checks for the rest of the day.
5 The rituals trapped within the sorcerer’s brain are too much for your body to bare: you collapse on the ground as your body spasms. The character takes a dCarcosa of damage.
6 You hear voices in your head? Or maybe your stomach. The sorcerer’s personality has survived within the ritual magic burned deep within his brain. The characters decision making is impaired while his mind fights to push out the invading id: the DM may request the character re-roll any die rolls (when doing so will be most annoying) if the player fails a Save vs. Magic. This effect lasts for the remainder of the session.
7 Oh God: roll on the random mutation table.
8 Delicious: you recover all your HP.

Coming Out of Retirement

by Ramanan Sivaranjan on November 18, 2014

Tagged: odnd carcosa homebrew mastersofcarcosa

At the start of 2014 I decided I would finally run a game of D&D, rather than always being a player. It was a sort of gaming New Years resolution. If you read this blog you can probably guess what I wanted to run: a game set in the doomed world of Carcosa! I started writing up rough notes for where the campaign would begin, and fleshed out a small region within the larger world map for players to explore. I then sat on those notes for 8-9 months.

Deciding what to run and how to run it wasn’t that difficult. My main stumbling point was getting over myself and actually running a game. I hadn’t DM’d anything in probably 20 years, if not longer. It seems weird to feel apprehensive about an activity little children do without much fuss. I’d talk about running a game, eventually, and leave it at that. Until yesterday.

Being on the other side of the DM screen was a strange experience. I didn’t find it as stressful as I had thought it would be. Because everyone I normally game with was busy it was just me and two players, Eric and Gus, but that was probably for the best. I found the logistics of managing players was probably easier. I decided to run an OD&D, a system so poorly fleshed out you don’t really have to worry about playing the game wrong. The nice thing about our group is that we all have a rough sense of how to play an OD&D game, and make the same sorts of assumptions when playing. The adventure we were playing was one I made myself. That familiarity with the material probably helped the game run smoothly.

I think the session went well enough, but I have been trying to reflect on what I need to do better. I want to run a Carcosa game with a healthy dose of He-Man, but this first session lacked anything that would suggest a Masters of the Universe vibe. I don’t think I did that great a job highlighting what makes the world weird. The dungeon I had made was supposed to seem mostly empty, with the big reveal being, “oh shit it’s actually full of Bone Men!” I think the actual result of the session lacked that critical, “oh shit.” From the game side of things, I need to firm up when I roll for random encounters. I was too inconsistent here, sometimes letting the players search without consequence or travel through larger chunks of the dungeon unmolested.

All in all it was a lot of fun. In hindsight there was really no way it wouldn’t have been. I think the people you play with really make or break this stuff.

20 Quick Questions for your Campaign Setting

by Ramanan Sivaranjan on May 10, 2014

Tagged: carcosa campaign mastersofcarcosa

I also wrote this up some time ago for a Carcosa campaign I may never run. Jeff Rients suggested 20 questions about your campaign setting that would provide just enough backstory that your players could figure out what’s up without needing some crazy info-dump they’ll just tune out anyways.

  1. What is the deal with my cleric’s religion?

    There are no clerics. Problem solved!

    There isn’t much proper religion to speak of in the world of Carcosa. Some people worship the Old Ones and their spawn, others ancient technology. No one is worshiping otherworldly benevolent beings. There are certainly no centralized religious organizations.

  2. Where can we go to buy standard equipment?

    Characters begin in the town of Invak. One can find most standard equipment for sale in the town in a large shop run by “the Infinite Keeper”. The Brown Men village of Jahar to the South may have other items that are trickier to track down. Trade caravans run between the two towns.

  3. Where can we go to get plate mail custom fitted for this monster I just befriended?

    You are unlikely to find anyone in the region who knows how to produce plate mail, let alone the metal you would need to produce it. “The Ocean of Humility” in Invak may be able to fashion something out of leather. Most people have little idea how to fashion useful armour that fits people, let alone monsters.

  4. Who is the mightiest wizard in the land?

    The most evil of all the Purple Men, “the Icon of Judgment,” is known throughout the land for his mastery of sorcery. He rules a small village protected by advanced weaponry and battle armoured soldiers. The Old Ones yield to his will.

  5. Who is the greatest warrior in the land?

    You know of no greater soldier than “the Swift and Silent Beginning,” the leader of the Bone Men village Invak.

  6. Who is the richest person in the land?

    “The Icon of Judgment” is said to possess vast amounts of wealth.

  7. Where can we go to get some magical healing?

    Nowhere. Sorcery is only used for evil and wickedness.

  8. Where can we go to get cures for the following conditions: poison, disease, curse, level drain, lycanthropy, polymorph, alignment change, death, undeath?

    The desert lotuses can heal the sick and dying. Of course, they can also kill you.

  9. Is there a magic guild my MU belongs to or that I can join in order to get more spells?

    There are no traditional magic-users, and sorcerers are definitely not forming guilds: they are two busy harvesting each other for fuel for their spells.

  10. Where can I find an alchemist, sage or other expert NPC?

    “The Falling Flower” is a Desert Lotus Apothcary who lives in the village of Invak. He operates a small stall in the ex-slaves quarter of the town. He may be addicted to the lotuses he sells.

    The nearest sage you know of is “He of the Air,” who lives in Jahar.

  11. Where can I hire mercenaries?

    The town of Invak maintains an informal standing milita. Most of the men and women in the town have served. For a little money it won’t be hard to find people willing to have an adventure.

  12. Is there any place on the map where swords are illegal, magic is outlawed or any other notable hassles from Johnny Law?

    Most people consider magic wicked. You are best to hide any sorcerous tendencies you may have. On the other hand, no villagers are likely to complain about a person carrying a weapon: it’s rough out there.

  13. Which way to the nearest tavern?

    This Way to Death in Invak serves fermented drinks and is the place to go for all sorts of shadiness.

  14. What monsters are terrorizing the countryside sufficiently that if I kill them I will become famous?

    A large spherical hunter-killer robot stalks the wastes around Invak at night. No one knows who created it or for what purpose, but it has been stealing away men and women for as long as anyone can remember. Few have encountered the machine and lived to share their tales.

    “The Swift and Silent Beginning” will pay for proof of any killed slaver or spawn.

  15. Are there any wars brewing I could go fight?

    Occasionally a town and its leader may get bold and try to expand their reach or power: this rarely ends well for anyone involved. There are currently no large scale wars of note.

  16. How about gladiatorial arenas complete with hard-won glory and fabulous cash prizes?

    A castle of Orange Men to the North run a gladiatorial arena of sorts: there are no prizes and the winners of the games are fed to the Spawn of Shub-Niggurath the Orange Men worship as a god.

  17. Are there any secret societies with sinister agendas I could join and/or fight?

    Maybe, but they are secret.

  18. What is there to eat around here?

    In Invak people subsist off the meats and eggs of the various lizards that make their home in the wastes, along with mushrooms and all sorts of strange roots. There is nothing good to eat anywhere.

  19. Any legendary lost treasures I could be looking for?

    The Elder Signs, rune inscribed stones that keep the Old Ones at bay, would probably be quite handy.

  20. Where is the nearest dragon or other monster with Type H treasure?

    Few creatures are interested hoarding treasure on Carcosa besides the various races of Men. Of course, it’s not clear what anyone actually does with their piles of gold and jewels: Carcosa is a crap hole world with nothing good to buy.

20 Quick Questions: Rules

by Ramanan Sivaranjan on May 05, 2014

Tagged: carcosa campaign mastersofcarcosa

I wrote this up some time ago for a Carcosa campaign I may never run. Brendan of Necropraxis suggested answering these questions as a way to help new players quickly get a sense of what’s up with your particular game of D&D. I haven’t ran a game since I was a little kid, but if I did it’d probably look like the sort of games I’ve been playing since I got back into old-school D&D.

  1. Ability scores generation method?

    3d6 in order, just like God intended.

  2. How are death and dying handled?

    If your hit points drop below or are equal to zero make a Save vs. Death Ray and Poison: success indicates your character is merely unconscious, completely incapacitated until they can get a full week of rest; failure indicates your character is oh-so dead. If you roll a natural 20 on your saving throw roll, your character not only survives, but is invigorated by his near death. In this case your character re-rolls their HP for the session.1

  3. What about raising the dead?

    The ancient snake-men may have had a ritual for raising the dead, though it is currently lost to the ages. Perhaps intrepid adventurers may uncover such a spell, though I am sure the costs to cast it would make death look like the better choice.

  4. How are replacement PCs handled?

    Roll up a new character and we will jam them into the game somehow. It’s handy to have henchmen for such a situation.

  5. Initiative: individual, group, or something else?

    Individual: roll a d6, high roll goes first, your dexterity score is used to break ties.

  6. Are there critical hits and fumbles? How do they work?

    Yes: a 1 is always a miss, a 20 is always a hit and you deal the maximum damage for the attack.

  7. Do I get any benefits for wearing a helmet?

    Of course: helmets shall be splintered! 10% of hits that would damage a character will be to a character’s head. If the character is wearing a well made helmet it will shatter protecting them from the blow.

  8. Can I hurt my friends if I fire into melee or do something similarly silly?

    Yes, targets would be chosen at random when firing into the fray.

  9. Will we need to run from some encounters, or will we be able to kill everything?

    You will probably want to avoid some fights.

  10. Level-draining monsters: yes or no?

    Hells no: they are the worst.

  11. Are there going to be cases where a failed save results in PC death?

    Yes, but hopefully that won’t feel stupid. What’s the point of a Save vs. Death Ray if you don’t have death rays in your game?

  12. How strictly are encumbrance & resources tracked?

    Strictly! Bust out that spreadsheet, asshole.

  13. What’s required when my PC gains a level? Training? Can it happen in the middle of an adventure, or do I have to wait for down time?

    Leveling happens during down time. There is no need for special training.

  14. What do I get experience for?

    Finding treasure, killing monsters and terrible people, freeing slaves, stopping sorcerers, exploring the wilderness and anything else I can think of.

  15. How are traps located? Description, dice rolling, or some combination?

    Description, mostly.

  16. Are retainers encouraged and how does morale work?

    Yes, the more the merrier. Morale is handled using the obscure rules hidden within OD&D. When a morale check is required roll a 2d6, adjusted by a retainers loyalty, the higher the roll the better.

  17. How do I identify magic items?

    Characters may encounter ancient magical snake-men artifacts, or the great technologies of the Primordial Ones or the Great Race. Chances are nobody in Carcosa will know what’s up.

  18. Can I buy magic items? Oh, come on: how about just potions?

    Sorry, no.

  19. Can I create magic items? When and how?

    It is possible, through some long lost terrible sorcerous ritual that’s probably not worth the trouble when you can just go hunting for laser guns.

  20. What about splitting the party?

    That never works out, right?

  1. The “Hulkamaniac” rule.
