Hi, what happens to the souls of dead people/nephalems, do they exist somewhere ?
The souls of dead people cannot reach heaven or hell, so the vast majority of souls go to the spiritual plane of Sanctuary, the Unformed Land aka Mbwiru Eikura from Witch Doctor’s lore, however others still remain on the physical plane having to be put to rest in peace by necromancers, there is also another plane beyond the spiritual plane of Sanctuary, the Realm of Trag’Oul, there is where the first necromancer in History was created and where the first generations of nephalem are.
Trag’Oul is not only the guardian of Sanctuary, The One Who is Forever has a connection with all the human souls of Sanctuary, to maintain the Balance, the necromancers guide the souls towards its realm.
