I wish I could remember! My angel was just split off from an elder angel, they weren't human themselves. Any humans chosen were supposed to possess certain qualities, and their souls were withheld instead of allowed to rejoin the Earth Spirit, but I don't remember a whole lot of it now. Most of my pre-Severing memories are pretty abstract.

I've been keeping an eye open for angel stuff but aside from this all I'm finding is ranging from Precious Memories to Angels In The Outfield kind of material.
