On a lifeless island of black stone
stands the alien city of Carcosa.

This is Random Carcosa. You can use this website to generate random hex descriptions for a world derived from the information within and aesthetics of Geoffery McKinney's Carcosa. What's this all about?

This is very much a work in progress. If you need a random 1st level character for your Carcosa game, I've got you covered. If you need to roll a dCarcosa we can do that too.


1 B'yakhee.

About 10% of the hex descriptions in Carcosa are simple monster encounters.


Spawn of Shub-Niggurath (AC 13, MV 210 [swimming only], HD 1, Chaotic): a Purple quadruped with a smooth hide, no eyes, and a circular gaping maw. Harmed only by fire.

There are 103 Spawn of Shub-Niggurath encounters described in Carcosa.


Village of 374 Green Men ruled by a Lawful 6th-level Fighter.

Of the 800 hex descriptions in Carcosa a little more than a quarter describe a village, citadel, castle, or monastery.


7 Mutant Trachodon (AC 16, MV 120', HD 13, neutral). Scaled Jale hide. Prehensile tongue (swallow attack). Touch turns anyone to slime. Regenerate 1 HD every 1-3 rounds.

Several mutant dinosaurs are described in Carcosa.


Bipedal humanoid robot (AC 18, MV 120', HD 8) carrying a spear, with a single spotlight eye in the center of a cylindrical head. It is dragging a dead velociraptor behind it. It has learned how to hunt by spying on humans, but doesn't understand what to do with the dead animals: it just drags them back to its cave.

Most hex descriptions in Carcosa are kind of crazy.
