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 Cthugah's Flame Creature.

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


Spawn of Shub-Niggurath (AC 16, MV 210, HD 10, Chaotic): a Brown, Dolm, Orange and Blue anthropoid with a suckered hide, 5 eyes, and a circular gaping maw.

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


Citadel of 63 White Men who are currently leaderless.

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


6 Mutant Brachiosaurus (AC 16, MV 60', HD 32, neutral). Furred Purple hide. Covered in spines (when attacked in melee attacker takes a dCarcosa damage and it can throw them like a wyvern). Immune to heat/fire.

Several mutant dinosaurs are described in Carcosa.


Burnt out husk of a large Yellow tyrannosaurus rex.

Most hex descriptions in Carcosa are kind of crazy.
