Vrykul started having human offspring in -15.000
War of the Ancients was -10.000
That scene in the trailer could have taken place at any point between those events, which is also the explanation I expect Danuser and his drones would provide if people called them out on this, given that it’s an obvious oversight that’s protected by the ambiguity produced by their crap world building.
It’s more jarring that three of the Aspects have High Elf visage forms despite the fact High Elves don’t even exist for several millennia.
Fair, the exact point of human origin was lost to me
mainly because I recall the (retconned?) book about the war of the ancients where i think both the human and orc were considered freaks by the elves.
I’ve honestly stopped paying attention to the lore and it depresses me because I used to be a pretty sharp lorekeeper.
Dragons invented the high elf look as self expression. The exiled highborne saw the dragons in their visage forms and went “yeah, I want some of that!” and subsequently molded themselves by magic in the dragons’ image as a natural result of elven hubris, emulating the aspects.
