Dracoris

I've not seen the justification for it yet - my head canon is that Bolvar raised all the dudes who died as part of the Fourth War, but I'm withholding judgement on whether that's dumb or not til I see the reasoning.

That’s exactly how it is in the lore, and when he raised them they were asked if they wanted to return as DKs. Still doesn’t feel right to me

What's weirder than that for me is the Horde allied DKs. Surely Bolvar wouldn't want to help the Horde? Or is it that canonically this all happens post War but pre Sylvanas breaking the helm, and we're all best friends at that point?

I don't think you can see him as Bolvar anymore, death cares not for previous factions, in the end, they all ''serve'' the Lich King

I figure he has retained some level of control if he's allowing new DKs to adventure rather than just having them murder paladins like Arthas did? Admittedly DK lore is one of my weaker points though, I could well be wrong.

And it’s also true that the Lich King has never seen factions like horde/alliance. In Wrath the Ebon Blade was cross-faction, Acherus has always been open to both horde and alliance even when the factions are at war. Bolvar saw the Ebon Blade as useful against the legion too

Will be interesting to see what post-Helm Bolvar thinks about everything. I remember reading he'll be at the head of the Ebon Blade in Shadowlands, which is... a bit odd if he's not going to be Lich King anymore.

Control of the scourge (hence second invasion) but he can still raise people up and wield DK type powers, I don’t think he’s suddenly going to start wanging around judgement and consecration
