So in Legion, Warrior characters essentially 'die' and end up in the Halls of Valor working for Odyn. It's supposed to be "Warrior Heaven" - so is it apart of the Shadowlands? Or is it some halfway point between the realm of the living and the realm of the dead. Val'kyr appear there, and they are the ascended versions of Kyrians, if I read this all right. I remember the original idea behind the class hall was that we'd see heroic warriors of eld there, before Blizzard changed it to just being Vrykul.
