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.


1 Dolm Worm.

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


Spawn of Shub-Niggurath (AC 12, MV 90, HD 8, Neutral [intelligent]): a Yellow, Ulfire, Bone and Jale crustacean with a suckered hide, 6 eyes, and a beaked mouth. Invisible.

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


Castle of 39 Bone Men led by a Neutral 9th-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 Shield of Dreams".

Everyone you encounter in Carcosa has a ridiculous title.


9 Mutant Stegosaurus (AC 16, MV 60', HD 4, neutral). Feathered Red hide. Prehensile tongue (swallow attack). Can shoot tail spikes up to 60'. Surprised only on a 1.

Several mutant dinosaurs are described in Carcosa.


A beautiful young woman, an astronaut from Earth, lays wounded in a recently crashed spacecraft. The ship is damaged beyond repair.

Most hex descriptions in Carcosa are kind of crazy.
