With WoD on the way out, did we ever find out what was up with all the ghosts in Draenor?
We had the ghosts of dead Draenei, and that goes along with Auchindoun. We had dead orcs, but we've seen that before in TBC's Nagrand. We had dead trolls, but that seemed to be a voodoo thing. Alright, but then we have Admiral Taylor and his garrison, something that felt like a dropped thread to me. We also had Jarrod Hambly hanging around, I suppose we could say through the power of love. All in all though, it seemed like they were going to do something more with spirits than use them as a set up for Gorefiend. Otherwise, why throw in Ephial?
