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 Spawn of Yog-Sothoth.

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


Spawn of Shub-Niggurath (AC 12, MV 30 [land] / 60 [fly], HD 5, Chaotic): a Bone insectoid with a scaled hide, 1 eyes, and a circular gaping maw.

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


Castle of 21 Ulfire Men led by a Lawful 10th-level Sorcerer.

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


A young Yellow Man child weeps alone. He has no possessions save his clothes, and is hungry.

Most hex descriptions in Carcosa are kind of crazy.
