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.


3 Cthugah's Flame Creatures.

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


Spawn of Shub-Niggurath (AC 12, MV 120 [land] / 120 [fly] / 120 [swim], HD 3, Chaotic): a Yellow batrachian with a suckered hide, 6 eyes, and multiple mouths. Surprised only on a 1.

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


Citadel of 38 Orange Men led by a Lawful 5th-level Fighter.

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


You meet "the Prince of the Bringer".

Everyone you encounter in Carcosa has a ridiculous title.


10 Mutant Trachodon (AC 16, MV 120', HD 12, neutral). Smooth Red hide. Pillow-like consistency, immune to bludgeoning attacks.

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.
