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.


3 Pterodactyls.

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


Spawn of Shub-Niggurath (AC 14, MV 120 [land] / 120 [fly] / 180 [swim], HD 10, Chaotic): a Yellow icthyoid with a scaled hide, 5 eyes, and no mouth.

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


Village of 321 Black Men ruled by a Lawful 9th-level Sorcerer.

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


3 Mutant Archelon lschyras (AC 18, MV 30' [150' Swim], HD 10, neutral). Furred Red hide. Poisoned tail spikes has the effect of green lotus powder. Immune to cold.

Several mutant dinosaurs are described in Carcosa.


Strange ritual space made up of crucified White Man, small clay jars of water and dried herbs.

Most hex descriptions in Carcosa are kind of crazy.
