It's still a little hard for me to grasp the idea of them being risen as undead because given that they are titan-forged constructs that haven't been given the curse of flesh it's still difficult to wrap my mind around them being raised as undead.
This is also sparks questions as to who is raising them, could some of them theoretically be Earthen raised during Arthas' conquest of Northrend or dead Earthen raised by Bolvar from the Storm Peaks that we haven't seen till now? If so could Frostborn also be raised as undead?
On the other hand could it be that the Ebon Blade is up to shenanigans and decided to raise more people in secret?
I want to know people's thoughts!
