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.


17 Diseased Guardians.

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


Spawn of Shub-Niggurath (AC 12, MV 150 [land] / 150 [swim], HD 2, Chaotic): a Green amoeboid with a feathered hide, 5 eyes, and a circular gaping maw. Its touch causes sickness (lose 1 Con / day until dead). Regenerate 1 HD every 1-3 rounds.

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


Village of 337 Jale Men ruled by "the Sun by Whom All See," a Lawful 5th-level Fighter.

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


Mutant Plesiosaurus (AC 14, MV 150', HD 20, neutral). Suckered Yellow hide. Can split into smaller versions of itself, like Voltron in reverse.

Several mutant dinosaurs are described in Carcosa.


1 Deep One.

Most hex descriptions in Carcosa are kind of crazy.
