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 Primordial Ones.

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


Spawn of Shub-Niggurath (AC 13, MV 90 [swimming only], HD 3, Neutral [unintelligent]): a White quadruped with a suckered hide, 2 eyes, and a toothed mouth. Surprised only on a 1.

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


Castle of 35 Red Men led by "the Mistress of Sleepers," a Neutral 8th-level Sorcerer.

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


8 Mutant Pteranodon (AC 14, MV 30' [150' Fly], HD 3, neutral). Scaled White hide. Multiple/insectile eyes, multiple mouths, 2-9 heads. Radioactive (if killed explodes for 2 dice radiation damage to all within 100'). Harmed only by fire.

Several mutant dinosaurs are described in Carcosa.


12 Black Men led by putrid smelling Sorcerer (AC 18, MV 120', HD 3, Chaotic) are in the middle of casting Manifestation of the Putrescent Stench. The Sorcerer is armed with a laser pistol and wears a bright orange alien space suit.

Most hex descriptions in Carcosa are kind of crazy.
