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.


93 Space Aliens.

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


Spawn of Shub-Niggurath (AC 20, MV 30 [land] / 180 [fly], HD 6, Chaotic): a Ulfire arachnoid with a feathered hide, 3 eyes, and multiple mouths. Immune to poison.

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


Village of 305 Ulfire Men ruled by a Neutral 7th-level Sorcerer.

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


3 Mutant Styracosaurus (AC 17, MV 60', HD 13, neutral). Suckered Jale hide. Immortal. Will resurrect 1 minute after apparent death.

Several mutant dinosaurs are described in Carcosa.


4 Snake Men attempt to repair a time machine. The Snake Men and their collection of high-tech gadgetry are incomprehensible to characters with an intelligence score less than 18.

Most hex descriptions in Carcosa are kind of crazy.
