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.


2 Cthugah's Flame Creatures.

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


Spawn of Shub-Niggurath (AC 15, MV 180, HD 7, Chaotic): a Yellow, Purple and Dolm octopoid with a furred hide, 6 eyes, and no mouth. Immune to normal weapons.

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


Citadel of 31 Red Men led by a Chaotic 8th-level Fighter.

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


3 Mutant Teratosaurus (AC 16, MV 180', HD 9, neutral). Feathered Green hide. Semi-gelatinous (suffer only half damage from weapons that are not electromagnetic or elemental).

Several mutant dinosaurs are described in Carcosa.


The mutilated bodies of two Ulfire children lay next to the dead body of a Purple Sorcerer. On the Sorcerer's person is a book outlining how to cast The Accursed Sounding of the Void.

Most hex descriptions in Carcosa are kind of crazy.
