That is an absolute nonsense. We know of examples of people’s souls going into the Light, we have ancestor cults where entire races commune with the spirits of their forebears. Druids were known to enter the Emerald Dream upon death as far back as Classic. Hell, Legion even has quests where you send Death Knight NPCs into the Shadowlands to harvest essences from souls of known characters.
When you resurrect Whitemane she says
High Inquisitior Whitemane says: I… I live? Is the anguish of death over?
The idea that any character in Warcraft would think that existence would end after Death is competely and utterly stupid.
This would almost work as an explanation if not for the fact that the Nerubians themselves based their architecture on the Tol’vir they conquered. Or are we supposed to believe these guys were secretly inspired by Maldraxxus as well?
The simple explanation is that they copied the Scourge’s aesthetic and then simply said “Maldraxxus did it first” without even looking at the prior world building that informed the Scourge aesthetic. It’s lazy and embarrassing.
That’s a lot of words to say “Souls that enter the Shadowlands from other timelines effectively stop existing”… which is bad news for Mag’har players, I suppose.
It’s the same stupidity that led them to proclaim stuff like “the Legion transcends all timelines
” simply because it sounds cool, without considering any of the implications it might have.
You don’t seem to be looking very closely at all.
