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.


6 individuals of Species 23750.

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


Spawn of Shub-Niggurath (AC 16, MV 210, HD 8, Neutral [intelligent]): a Dolm arboreoid with a scaled hide, no eyes, and no mouth. Regenerate 1 HD every 1-3 rounds.

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


Citadel of 87 Green Men led by "the Eater of Invincibility," a Neutral 5th-level Fighter.

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


10 Mutant Iguanadon (AC 16, MV 150', HD 10, neutral). Feathered Red hide. Extremely cold (1 die damage per round to all within 20').

Several mutant dinosaurs are described in Carcosa.


Small inexplicable pond, filled with brightly colored fish. The fish are easily caught and if eaten will grant a temporary +4 HP for the day. The pond and fish will be gone upon return, and attempts to preserve the fish will result in unpleasant smelling mess.

Most hex descriptions in Carcosa are kind of crazy.
