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 16, MV 210, HD 5, Chaotic): a Bone anthropoid with a suckered hide, no eyes, and multiple mouths.

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


Citadel of 52 Bone Men led by "the Captain of Lords," a Lawful 6th-level Sorcerer.

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


9 Mutant Pentaceratops (AC 15, MV 90', HD 10, neutral). Scaled White hide. Prehensile tongue (swallow attack), metal body.

Several mutant dinosaurs are described in Carcosa.


A Purple Man hangs limp from a tree. He is pierced head to toe by spikes. Two tridents lay near his lifeless body.

Most hex descriptions in Carcosa are kind of crazy.
