1. The item was given power by the energy of Icecrown Citadel, and thus has to be connected to Northrend in some way, even if not located there in-game.
2. It has to be a weapon (most likely not able to be equipped in-game) of some sort that's crude and brutal.
This said, I'd like to unfortunately suggest we rule out the ghost wedding. It seems to have nothing to do with either of the above. Right now, in my opinion, Abominations are our best lead.
