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.


2 Stegosauruses.

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


Spawn of Shub-Niggurath (AC 20, MV 120 [land] / 60 [swim], HD 5, Chaotic): a Dolm and Bone amoeboid with a suckered hide, 1 eyes, and no mouth. Its touch causes paralysis. Immune to normal weapons.

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


Village of 149 Blue 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 Glorious Shield".

Everyone you encounter in Carcosa has a ridiculous title.


3 Mutant Triceratops (AC 15, MV 90', HD 18, neutral). Furred Purple hide. No mouth, metal body. Extremely cold (1 die damage per round to all within 20'). Immune to poison.

Several mutant dinosaurs are described in Carcosa.


A T-Rex corpse, skin mottled red and orange, is being feasted upon by fist-sized maggots. The top of its skull has been removed with surgical precision, and its brain is missing.

Most hex descriptions in Carcosa are kind of crazy.
