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.


10 Mi-Go.

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


Spawn of Shub-Niggurath (AC 16, MV 240 [land] / 120 [fly] / 90 [swim], HD 6, Neutral [unintelligent]): a Ulfire octopoid with a smooth hide, 2 eyes, and a circular gaping maw. The creature shoots spikes (1 die damage).

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


Citadel of 74 Bone Men led by a Neutral 11th-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 Meek Mirror".

Everyone you encounter in Carcosa has a ridiculous title.


6 Mutant Stegosaurus (AC 16, MV 60', HD 7, neutral). Feathered Dolm hide.

Several mutant dinosaurs are described in Carcosa.


A foreboding grey castle sits empty save for its custodian, an Orange Woman 18th-level Sorcerer. The castle is circumscribed by a bottomless chasm. A single bridge leads to its imposing doors shaped in the visage of a skull. The sorcerer will not leave the castle, and is immortal and invulnerable while within its walls. She will aid all those who actively seek to defend Carcosa from the forces of Chaos.

Most hex descriptions in Carcosa are kind of crazy.
