Great Old One Name Generator

Great Old Ones such as Cthulhu, Hastur, Tsathoggua and Ithaqua are ancient, physical beings bound to specific places on Earth or nearby worlds, usually sleeping or imprisoned and served by cults. Outer Gods such as Azathoth, Yog-Sothoth and Nyarlathotep are cosmic forces that exist outside ordinary space and time. This generator focuses on the first group: named, located, worshipped things.

Yes. The original true names and titles are free to use in any game or story. The canonical entries are included so you can compare sound and scale; the Lovecraft-authored ones are public domain, while entities created by later Mythos authors are best treated as reference rather than copied into commercial work.

Keep it to two or three chanted beats and let a hyphen mark the break: Ulgoth-Marr, Tlocha-Nuum, Kroth-Ummaq. Clusters like th, gg, kk and zh add weight without needing a dozen consonants in a row. If your players stumble over it, that is fine; that is what the cult title is for.

Titles that describe location and appetite work best: The Sleeper Beneath the Salt, The Hunger Under the Mountain, The Thing That Waits in the Well. Avoid describing the shape directly; leaving the body to the imagination is where the horror comes from.
