CTHULHU

"Ph'nglui mglw'nafh Cthulhu R'lyeh wagh'nagl fhtagn." -- "In his house in R'lyeh dead Cthulhu waits dreaming." R'lyeh is a great sunken city of non-Euclidian geometry hidden somewhere beneath the ocean. So bizarre is its construction that anyone entering the city (which occasionally rises above the waves) must make saving throws at +4 against fear and insanity. Cthulhu lies in a huge stone structure sealed with the Elder Sign (q.v.). If the seal is broken and the god released, everyone (and/or everything) in a radius of 100 miles must make a saving throw against death or go insane. This insanity lasts for a number of months equal to the creature's intelligence.

Cthulhu usually attacks both physically and psionically. He can regenerate 10 hit points per melee round. He teleports up to one-half mile at will and is totally immune to the effects of water, cold, and vacuum. He can call up from the sea 10-100 of the Deep Ones. He will retreat into his lair if confronted with an intact Elder Sign, another of the Old Ones (such as Hastur), or some natural catastrophe, such as the re-sinking of the city of R'lyeh into the sea.

Cthulhu is served by the Deep Ones as well as his human worshipers, who often interbreed with fish-men. Cthulhu's cult is usually hidden and secret, and is dedicated to bringing about Cthulhu's return and conquest of the world.
