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 Ulfire Jelly.

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


Spawn of Shub-Niggurath (AC 16, MV 90 [swimming only], HD 4, Chaotic): a Green fungoid with a suckered hide, 6 eyes, and a toothed mouth. Immune to surprise.

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


Village of 215 Brown Men ruled by a Neutral 5th-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 Adept of Autumn".

Everyone you encounter in Carcosa has a ridiculous title.


12 Mutant Plateosaurus (AC 16, MV 80', HD 4, neutral). Furred White hide. Can cast invisibility at will. When visible, has see-through skin like a Bone Man. Harmed only by fire.

Several mutant dinosaurs are described in Carcosa.


A White Woman (AC 14, MV 120', HD 4, Lawful) is locked in battle with a Deep One. She fights with a large wooden staff and is searching for her mother.

Most hex descriptions in Carcosa are kind of crazy.
