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.


10 Primordial Ones.

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


Spawn of Shub-Niggurath (AC 14, MV 60, HD 4, Chaotic): a Green quadruped with a scaled hide, 1 eyes, and no mouth. Harmed only by fire.

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


Village of 358 Bone Men ruled by "the Overseer of Humility," a Lawful 11th-level Fighter.

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


7 Mutant Lambeosaurus (AC 15, MV 120', HD 12, neutral). Smooth Blue hide. Suckered mouth, tentacles instead of legs. Covered in spines (when attacked in melee attacker takes a dCarcosa damage and it can throw them like a wyvern).

Several mutant dinosaurs are described in Carcosa.


A Green Man cyborg (AC 18, MV 60', HD 6, Lawful) leads a battalion of 3-12 soldiers armed with an assortment of Alien weaponry. The cyborg will repair any Alien technology Lawful PCs may possess, and will attack any PCs who make their allegiance to the forces of Chaos known. He is searching for his adopted daughter.

Most hex descriptions in Carcosa are kind of crazy.
