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.


4 Unquiet Worms.

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


Spawn of Shub-Niggurath (AC 12, MV 150 [swimming only], HD 2, Chaotic): a Green octopoid with a smooth hide, 4 eyes, and a beaked mouth. The creature shoots spikes (1 die damage). Immune to normal weapons.

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


Citadel of 63 Black Men led by a Neutral 4th-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 Eater of Sublime Wisdom".

Everyone you encounter in Carcosa has a ridiculous title.


3 Mutant Ankylosaurus (AC 21, MV 60', HD 7, neutral). Furred Black hide. Immune to poison.

Several mutant dinosaurs are described in Carcosa.


Ancient runes are carved into earth, filled with red clay.

Most hex descriptions in Carcosa are kind of crazy.
