Something that I don't understand.
This is not about classic wow lore, but I've been following the lore of the game even if I'm not playing retail, and last part of legion gave me something to think about.
If the pantheon was dead or at least a minimum part of their power came to Azeroth, why were they sargeras cautives?
If chronicles told us that all demons can regenerate themselves in the void, why Argus was used to regenerate demons? It was to regenerate them out of the void? I think it could be a possibility.
