I hope you find one soon . Do you play on US East? If so, we could probably do some rifts or GRs or something and try to find one.
I saw him once or twice, though I don't recall anything special about him... he may be. Usually I remember purples, especially ones I haven't seen before (like Erra, Smasher of Heavens or w/e) but all I recall of Emberdread is that his name reminded me of Everdread from Earthbound.
