Mystery Horrors

[PsychosisGnome]

Hey, everyone! This is my first time posting on the forums for this awesome game. But let's get straight to business.
I've been looking at some the monsters in the index, and I'm not sure what exactly what they are or where they appear. Specifically:

#623 KingOfTheWorld- Looks like a doom horror, similar to Eater of Dreams, but I don't think he's tagged as one. My suspicion is that he is what happens when you wish for "king of the world" aka a nasty reward for wishing for too much, as that wish occupies its own entry.

#1911 DefilerOfDreams- Looks like nothing else, but sounds like a doom horror. Once again, I don't think he is tagged as a doom horror. Related to R'lyeh in any way?

Thanks for humoring my crazy questions.
