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.

I was still apparently not confident the game was actually fun, 9 sessions in. Reading these recaps now it’s funny how unsure I was about this game.
