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.


7 Mi-Go.

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


Spawn of Shub-Niggurath (AC 19, MV 210 [land] / 210 [fly], HD 5, Chaotic): a Brown ooze/slime with a smooth hide, 5 eyes, and multiple mouths. Immune to heat/fire.

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


Castle of 62 Black Men led by "the Inestimable Lord," a Neutral 8th-level Fighter.

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


4 Mutant Brontosaurus (AC 16, MV 60', HD 30, neutral). Scaled Dolm hide. Prehensile tongue (swallow attack), 2-9 heads. Immune to cold.

Several mutant dinosaurs are described in Carcosa.


Village of 130 Dolm Men ruled by "The Master of the Universe," a 1st Level Fighter. He wields a magic sword in battle: on command the sword grants +20 HD, and the saving throws of a 20th level Fighter. Only those chosen by the powers of the Grey Castle may hold aloft the magic sword.

Most hex descriptions in Carcosa are kind of crazy.
