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 Ulfire Jelly.

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


8 Spawn of Shub-Niggurath (AC 17, MV 120 [land] / 90 [fly], HD 7, Neutral [unintelligent]): a Yellow crustacean with a scaled hide, 2 eyes, and a beaked mouth.

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


Village of 372 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.


You meet "the Overseer of Peace".

Everyone you encounter in Carcosa has a ridiculous title.


9 Mutant Stegosaurus (AC 16, MV 60', HD 10, neutral). Suckered Dolm hide. No eyes, no mouth. Surprised only on a 1.

Several mutant dinosaurs are described in Carcosa.


A floating circular platform of Space Alien technology hovers 15' above the ground. 1 in 6 chance to figure out how to operate (intelligence modifier applies, only one attempt per character). Can be moved at a rate of 10' per turn. 3 Bone Men with spears have built a hut on top, and "desert fishing lines" hang from the platform. The Bone Men are extremely xenophobic (reaction roll penalty of 2). One of the Bone Men has 2 sleep gas grenades (as sleep spell but a save versus paralysis applies, 30' blast radius).

Most hex descriptions in Carcosa are kind of crazy.
