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 Mummy Brain.

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


Spawn of Shub-Niggurath (AC 20, MV 180 [land] / 150 [fly], HD 8, Neutral [unintelligent]): a Yellow plant with a scaled hide, no eyes, and no mouth.

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


Citadel of 119 Purple Men led by a Neutral 4th-level Sorcerer.

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


You meet "the Effulgence of the Stars".

Everyone you encounter in Carcosa has a ridiculous title.


13 Mutant Stegosaurus (AC 16, MV 60', HD 12, neutral). Scaled Purple hide. Touch turns anyone to slime. Immune to surprise.

Several mutant dinosaurs are described in Carcosa.


Hidden underground lair of 43 White zealots led by a Lawful 5th-level Sorcerer.

Most hex descriptions in Carcosa are kind of crazy.
