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.


9 Stegosauruses.

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


Spawn of Shub-Niggurath (AC 14, MV 60 [land] / 90 [fly] / 90 [swim], HD 5, Chaotic): a Black quadruped with a feathered hide, 1 eyes, and no mouth. The creature shoots spikes (1 die damage). Its touch turns anyone to slime. Immune to cold.

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


Castle of 79 Jale Men led by "the Radiance of Wisdom," a Lawful 8th-level Fighter.

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


5 Mutant Pteranodon (AC 14, MV 30' [150' Fly], HD 1, neutral). Furred Purple hide. Pillow-like consistency, immune to bludgeoning attacks. Surprised only on a 1.

Several mutant dinosaurs are described in Carcosa.


Spawn of Shub-Niggurath (AC 18, MV 90' / 120' [swimming], HD 3, Neutral [intelligent]): an orange anthropoid with scaly skin, two yellow eyes, and a toothed mouth. One of its arms is an oversized claw. In its other hand it carries a green mace.

Most hex descriptions in Carcosa are kind of crazy.
