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 14, MV 240 [swimming only], HD 3, Neutral [intelligent]): a Black amoeboid with a smooth hide, 4 eyes, and a beaked mouth. The creature has 2-9 heads. Harmed only by fire.

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


Village of 189 Jale Men ruled by a Lawful 14th-level Fighter.

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

Several mutant dinosaurs are described in Carcosa.


A War-Machine, ancient and blasted; once a terror, now a collection of rust.

Most hex descriptions in Carcosa are kind of crazy.
