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 Dolm Ooze.

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


Spawn of Shub-Niggurath (AC 14, MV 90, HD 10, Neutral [unintelligent]): a Bone batrachian with a feathered hide, 4 eyes, and multiple mouths. Immune to poison.

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


Citadel of 80 Purple Men led by a Neutral 6th-level Fighter.

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


5 Mutant Ankylosaurus (AC 21, MV 60', HD 10, neutral). Suckered Bone hide. Immortal. Will resurrect 1 minute after apparent death.

Several mutant dinosaurs are described in Carcosa.


A large bird of prey stalks the players. After 1-3 hours it will turn and fly off into the distance. The bird does not attempt to hide its presence.

Most hex descriptions in Carcosa are kind of crazy.
