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 Cthugah's Flame Creature.

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


Spawn of Shub-Niggurath (AC 17, MV 120 [land] / 240 [fly], HD 9, Chaotic): a Purple arboreoid with a suckered hide, 1 eyes, and a circular gaping maw.

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


Village of 394 Brown Men ruled by a Chaotic 2nd-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 Clear Effulgence".

Everyone you encounter in Carcosa has a ridiculous title.


2 Mutant Tyrannosaurus Rex (AC 16, MV 150', HD 17, neutral). Furred White hide. Circular gaping maw. Can split into smaller versions of itself, like Voltron in reverse.

Several mutant dinosaurs are described in Carcosa.


The bodies of countless Dolm Men spill out of a door set into the side of a mountain and completely fill the 10' wide shaft leading into the underground. Obscured by the bodies are ancient Snake Men runes describing 2-8 random sorcerous rituals.

Most hex descriptions in Carcosa are kind of crazy.
