I've been looking around other TES websites and they talk about CHIM. I don't know what that is...so can someone please explain it? (I understand most of the stuff about Daedra, Aedra, and Anu/Padomay...but once people start getting into The Godhead and CHIM, I get lost.)

There's already an active thread about CHIM in the lore forum.
