So the Cursed Woods bounty had me take a few screenshots. One because of the clear reference to Kashyyk from Star Wars.
The other was this sighting of zombies –
These are shuffling corpses, or the reanimated dead. Peculiarly, they have blue eyes. The only other zombie reference to have had blue eyes was in Game of Thrones, and those were Wights.
These were the reanimated dead that the Whitewalkers created to raise an army against the living. Presently, we know they are making a march against the wall, and can only be killed with Valyrian steel or those Dragonshard knives. The wights in Diablo III however, can be killed as long as you have enough damage output.
We also have Dragons in Diablo, next time will check the name of those serpents.
(Edit) I came back to this post after a year and the next Season of Game of Thrones was already out. There has been more lore exposed about the whitewalkers and how they were created.
