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.


11 Mummies.

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


Spawn of Shub-Niggurath (AC 13, MV 210, HD 7, Chaotic): a Ulfire amoeboid with a suckered hide, 1 eyes, and a suckered mouth. Invisible.

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


Village of 143 Red Men ruled by "the Majestic Overlady," a Neutral 6th-level Fighter.

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


You meet "the Ocean of Radiance".

Everyone you encounter in Carcosa has a ridiculous title.


2 Mutant Paleoscincus (AC 24, MV 30', HD 7, neutral). Feathered Black hide. Extremely hot (1 die damage per round to all within 20'). Immune to cold.

Several mutant dinosaurs are described in Carcosa.


A damaged Alien vehicle, with 4 tank treads instead of wheels. Characters with an intelligence of 16 or more may attempt to repair the machine, with a cumulative chance of 10% per week of succeeding. (i.e after ten weeks the tank will be repaired.) It is large enough to comfortably transport 12 men.

Most hex descriptions in Carcosa are kind of crazy.
