So swain wants to kill the Noxian King correct? Does anybody know who the Noxian king is?

He wants to kill the Demacian King. I guess you can say the Noxian leader too since he wants to rule. This guy has some ambition!

well, just because he wants to be the ruler of noxus, it doesnt mean he wants to kill him. maybe just banish him to the dungeons to be tortured. he seems like the kind of guy who enjoys a good torturin

Oh, got my city-state messed up, thanks. We don't know who exactly the Demacian king is correct?

It's king Jarvan the Third, I think. I don't think there's any art on him though.

By Xin Zhao's lore its Jarvan III, no art on him yet, but hey who knows?

As for noxus, not much has been fleshed out yet

There's no king in Noxus, if I recall correctly. The city is ruled by a military dictatorship (think the Communist Party minus Communist) which is headed by a council (?) of high placed generals. Katarina isn't therefore a -real- princess, most probably the correct label would be noble or aristocrat.

As far as I understand from his judgement, Swain is quite the megalomaniac type, since he'd have to overthrow the entire High Command to set up a monarchy.... Plus he's pretty much a copycat off Ashe's intentions >_>;
