Okay, so I think I've locked in on the ABC acronym, but haven't fully narrowed it down a meaning yet. Right now I'm at

-Arcane Biology Compendium
-Arcane Biology and Civilizations
-Arcane Beasts and Critters (or Creatures)

or some permutation between those. Or the Arcane Beast and Creatures Field Guide or something like that. At least I feel like I have something slightly settled to work off of now instead of the nebulous pile of synonyms I've been mired in for weeks.
