For example, I had no idea there was a demon named "Amy." (You gotta imagine the other demons have a field day with that...) Or "Furfur" who is actually a pretty cool lookin' winged hart, although presumably a bad dude. Or that Belphegor, the demon of sloth, works primarily by inspiring labor saving inventions. Or that the Akkadian demon Humbaba* was titled "Guardian of the Fortress of Intestines."
These are good things to learn over breakfast.
*Whom I've actually heard of because of a game called "Rivers of Light" packaged with the Adventure Construction Kit on the Amiga 500, and YES, I do feel old now, thank you.
