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.


5 Primordial Ones.

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


2 Spawn of Shub-Niggurath (AC 15, MV 240 [land] / 210 [fly] / 60 [swim], HD 5, Chaotic): a Red octopoid with a smooth hide, 4 eyes, and a toothed mouth.

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


Village of 309 Yellow Men ruled by a Neutral 10th-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 Mistress of Sleepers".

Everyone you encounter in Carcosa has a ridiculous title.


15 Mutant Lambeosaurus (AC 15, MV 120', HD 15, neutral). Feathered Brown hide. Multiple mouths, 2-9 heads. Can shoot tail spikes up to 60'. Immune to cold.

Several mutant dinosaurs are described in Carcosa.


1 Sabertooth Tiger (intelligent).

Most hex descriptions in Carcosa are kind of crazy.
