Looks like our villains are beginning to cross paths. Chaos is coming. Noxus is at the center. We have Swain who hates GP and is probably aware of the other darkin and the void. He also hates Leblanc and knows about Morde.
We have Leblanc: enemy of Swain and Morde
We have Morde: iiterally the lord of death biding his time to kill Leblanc (or worse) which may draw Swains attention.
We have darkin: since they are all awake, it is a sure thing that they are reaving across Runeterra to destroy their enemies.
We have Kayn and Zed who are currently dealing with Jhin.
We have Jhin (see above)
We even have Sion trying to murder Irelia.
We have Sylas who hates Demacia and Noxus both.
I am not surprised if, after a battle between Noxus and Ionia with Demacia's help, SYlas tries to kill them both and while this happens Morde awakens. Then Kayn, Zed and the darkin sense chaos and make their way to crush some fools. Leblanc bides her time to eliminate Swain during all the chaos.
And yes I am spiraling here, but I love the idea of a huge villain vs villain fight. Like Morde vs Aatrox, then Rhaast awakens, then the void shows up or something.
