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 None, HD 1, Neutral [unintelligent]): a Jale fungoid with a suckered hide, 6 eyes, and a toothed mouth. Harmed only by fire.

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


Castle of 45 Purple Men led by a Lawful 2nd-level Sorcerer.

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


5 Mutant Brachiosaurus (AC 16, MV 60', HD 36, neutral). Feathered Orange hide. Can cast invisibility at will. When visible, has see-through skin like a Bone Man. Regenerate 1 HD every 1-3 rounds. Immune to heat/fire.

Several mutant dinosaurs are described in Carcosa.


What appears to be a simple rock is in fact The Starseed, a source of unlimited power. At any given time there are at least 1-6 high level sorcerers actively searching for the artifact.

Most hex descriptions in Carcosa are kind of crazy.
