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 Dolm Worms.

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


Spawn of Shub-Niggurath (AC 13, MV 120 [land] / 60 [swim], HD 5, Chaotic): a Jale quadruped with a smooth hide, 2 eyes, and no mouth. Invisible. Immune to heat/fire.

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


Village of 240 Bone Men ruled by "the Reflection of Sleepers," a Neutral 5th-level Fighter.

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


5 Mutant Velociraptor (AC 14, MV 180', HD 2, neutral). Scaled White hide. Suckered mouth. Harmed only by fire.

Several mutant dinosaurs are described in Carcosa.


Strange ritual space made up of crucified Black Man, small clay jars of water and dried herbs.

Most hex descriptions in Carcosa are kind of crazy.
