Some of the things they tease with the lore are very odd and random red-herrings for no reason, though
Remember when the Hallowed Blight event gave us a story a day about Benedict Baker, and it seemed to hint that he was transforming into a beast? "It's here. The entity has found me."? Absolutely no word of it since
You'd have thought it was a pretty good way of teasing that one of the next killers (this was pre-Legion) would be him, but guess not.
