Well, I'm excited. I've got a whole little arc in mind for Hallam. Dabbling with fel energies might prove... corrupting.

As for Saidan, which sounds suspiciously like Satan (shame on you naughty Blizzard Devs), imagine how paranoid everyone is going to be after that? Anyone could be a Nathrezim implant! Anyone! Like, maybe, Fandral Staghelm? I always suspected he was a Dreadlord, but as it turns out it was just Old God corruption. I was so disappointed, you have no idea.
