Mythic have added an overview of the Public Quest boss, Sildaen of Hoeth. As always the boss is tightly wound around the lore of Warhammer, and plenty of big words and confusingly pronounced names are used, so the authenticity is definitely there.

You can also check out some commentary over at Ten Ton Hammer, which specifically points out the mention of "White Lions" which were the rumored last class of the High Elves, that everyone pretty much consider confirmed already.
