It was magic, as far as I know, but necromancy. See, I was hanged on a very large special tree by a necromancer and her vampire husband. And well I don't remember the short term after that but there was a battle and a very large flash of magic nearby, and it woke me up? But that Necromancer died (sort of, long story) and a small little essence of her woke me up and remained with me until recently.
