This is somewhat of a discussion thread regarding the way souls behave when touched by a runeblade, specifically one imbued with domination magic. There is some inconsistency which goes to show how badly thought-out this whole lore is.
As we saw with Uther, when Shadownourne takes the soul of its victim, it actually cuts it in half and steals one half, with the other going to the Shadowlands as normal. By all accounts, the same should have happened to Sylvanas in WC3 when Arthas killed her.
The Sylvanas weâve known for 15+ years is the part that was stolen by Shadowmourne. But what about the other part? The one that should have gone to the Shadowlands? We see Zovaal bring out a crystal containing her other soul, so this means that heâs had it with him all along. But how? How was he able to get his hands on that soul? Mind you, Sylvanas in life was an honorable, brave and even caring person, defending her homeland until the very end. There is no way her other soul went to the Maw. It most probably went to one of the 4 other zones. Most likely Maldraxxus or Bastion. So how does Zovaal acquire the soul crystal?
Furthermore, she and Uther are by far not the only ones that Shadowmourne consumed. So why have we not seen any of the other souls in the Shadowlands, like King Terenas, Falric and Marwyn, all the Lordaeron people, all the dead High Elves, etc.? Moreover, why has nothing of the soul division been addressed in game this expansion, even though it is a MAJOR plot point that can turn the whole fabric of the game on its head?
Reason being that, as seen with the way Sylvanas behaved after her death - all cold, uncaring, damn near malicious, it begs the question how the rofl domination magic rofl affects the personality of the deceased. This would explain the cold and evil nature of the Undead in warcraft.
Problem: not all Undead were victims of Shadowmourne so this wouldnât fully explain the situation.
Anyway, what do you guys think? Can you wrap your heads around this new lore revelation?
