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 individuals of Species 23750.

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


Spawn of Shub-Niggurath (AC 13, MV 60 [land] / 90 [fly], HD 5, Neutral [intelligent]): a Dolm, Orange, Ulfire and Jale ophidioid with a scaled hide, 6 eyes, and no mouth. Its touch causes sickness (lose 1 Con / day until dead).

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


Citadel of 77 Green Men led 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 Empress of All".

Everyone you encounter in Carcosa has a ridiculous title.


2 Mutant Teratosaurus (AC 16, MV 180', HD 7, neutral). Suckered Purple hide. Genius Intelligence (18+ Int) and 1-4 psychic powers.

Several mutant dinosaurs are described in Carcosa.


A Blue Man Cyborg with a metal jaw and a robotic hook arm (AC 18, MV 90', HD 4, Chaotic) commands a group of 6-36 Blue Men bandits armed with bone weapons. The bandits demand the players hand over any metal items in their possession, which their leader will proceed to eat. The Cyborg earns +1 to hit for each piece of metal he consumes; this effect lasts one day. (When encountered he has a 0-3 bonus to hit.) His hunger for metal can not be satiated.

Most hex descriptions in Carcosa are kind of crazy.
