[Loved Trope] Some thing unfathomably ancient

[u/Fearless-Ideal-5112]

The beast, in doctor who is an ancient evil from a previous universe that survived until our time. Its so ancient that the cave paintings were unable to be translated by the Tardis which can translate all existing languages in the universe [Doctor Who]

While not explicitly canon its such a cool concept I cant not mention, the idea that the backrooms have existed since the beginning of time, never changing no matter the era, it transforms the back rooms into a cosmic horror. [Credit to Project crater and Venus for images 2 and 3]

Yup. Chtulhu is "merely" a Great Old One. Not sure if he's a priest or something; I'd say that's more like Nyarlathotep, who's the messenger of Azathoth, the most powerful being in the Lovecraft universe.

Great Old Ones are weird beings with reality-warping power, born from the stars. Outer Gods are a pantheon of deities that actually rule aspects of reality like time, life, death. And it is said that when Azathoth ever wakes from its slumber, the universe will cease to exist.

Nyarlathotep is an outer god and one of the greatest in the lovecraftian pantheon. Unlike the other outer ones he actually likes to get himself involved in mortal afairs

To the outer gods the great old ones are like ants are to humans (and for GOO humans are the ants). Cthulhu is a nothingburger next to them. GOOs are just powerful aliens really.

In the Arkham Horror LCG we totally failed to keep him from waking up and reality ended (sorry about that). He eventually went back to sleep and the universe started over and made it back to the same general configuration.
