Natalie Seline

Natalie Seline was a bishop from Lordaeron that, after the First War, began to delve into workings of the orc necrolytes who had poured through the Dark Portal and desecrated their hallowed dead. While at first this was done in order to provide Azeroth with the knowledge it needed to fight against such dark magic, her studies over the years became increasingly obsessed with finding out why such dark energies existed at all, and why she began to see the ebb and flow of such energies in the world around her. She began preaching about the necessity of balance between dark and light, but after her death, her books were locked away in the Kirin Tor's vaults in Dalaran.

The Cult of the Forgotten Shadow was created through the (re)discovery of her teachings by Forsaken priests in Lordaeron after the capture and refurbishing of the Undercity.
