How come LK was so enamored with Saronite?
Dude created an entire Necropolis out of it. It's so excessive, it makes me wonder if Yogg was messing with his mind.
Yet I always thought that the undead were strangely resistant to mind warping effects of Saronite, but I wonder if it didn't affect LK in a bad way in truth. We can't tell of course because Nerzhul or Arthas weren't really bastions of sanity on the first place. Then again, Yogg-Saron doesn't seem to care for LK even as a pawn and vice versa.
I wonder if Kil'jaeden realized Yogg was down there when he set Nerzhul up in the glacier?
