Arcane Arts and Corvids, part 1 is a manual in The Blood of Dawnwalker.
“Ravens, crows, and other corvids have a bad reputation, and deservedly so. One look into these birds’s cunning eyes is enough to send a shiver down the spine. They seem to know and see more than a simple animal should. In fact, they’re keenly attuned to what lies beyond the veil. They like the feel of aether almost as much as the scent of fresh blood.”
