Woah okay lots of things there. First,
Morath of Mourkain. I had no idea who he was until I searched for him and turns out he's a Time of Legends novel character. Second,
Cormac Bloodaxe. Another character I wouldn't have known if it weren't for the wiki. He's a novel character and son of a Norscan King who charged into Sigmar's Empire in 9 IC to take revenge for his father's death. The thing is, I don't think he was ever mentioned as an Everchosen in the wiki, but Aksel says he is, which is weird. The first Everchosen is Morkar, killed by Sigmar. Then Vangel, who seals U'zhul in to the Slayer of Kings and is eventually killed by Gromril Goldfist:
If Cormac is Everchosen, then he would be the Third or something like that, and considering his invasion is in 9 IC, that makes the timeline for the Everchosen extremely tight. It would indicate that the first couple of Everchosen were thrown at the world one after the other in quick succession and all of them were dealt with in quick measure, barely enough to even take it all in. Maybe I should only take the timeline in the wiki as a suggestion rather than an absolute.
