First off they would have to explain the split soul thingy. If his souls merged again after Arthas had been dealt with and Frostmourne destroyed. If that was already covered i would appreciate a link.
Then: All ghosts we summon to Azeroth are sent back to the Shadowlands as soon as they are done.
You summon them from the Shadowlands. So after youre done unless resurrected (which wipes out shadowlands memories until you die again) they get ported back. Either that or you will have some very angry Kyrians going ham at mortals doing that.
Hey the ancient egyptians belive, a person is composed non less than nine parts
Most ancient Egyptian funerary texts reference numerous parts of the person: Khet or the “physical body” Sah or the “spiritual body” Ren or the “True name, identity”, Ba or the “personality”, Ka or the " vital essence, double", that lingers in the tomb, protecting it and the body Ib or the “heart” Shut or the “shadow”, your darkest part Sekhem or the “power, true form of the soul”
and Akh or “intellect”, the combined spirits of a dead person that has successfully completed its transition to the afterlife
Since we don’t know how life and death and all these things works in WoW, maybe they took this multiple parts route…
I feel ashamed of his response…
Seriously? Its like a fanfiction writer saying Sylvanas & Anduin had a date but for some reason, it was wiped out of their memories.
I would understand this if it was introduced much earlier, but at this point, Shadowlands story feels like someone wants to insert a standalone story into the Warcraft universe by force.
