Elise is another champ that came to the Isles after the ruining occured, so she's not really a player in this story.

I'll expand on it more later, but after the Ruined King is killed, he does come back but as a spectre. He's most comparable to Kallista in that regard, slowly losing his identity and humanity and becoming more singularly focused. He leaves the Isles and tries to find Evelynn, and that's as far as I'll probably go with his story.

As for Maokai, his lore states that he did indeed save the last living piece of the Shadow Isles (which I'll call the "Heart" for simplicity's sake), and I figure that Mordekaiser is indeed after it, likely to hoping to use it to escape his metal prison. However, Mordekaiser and his army of undead are bound to the Black Mist, and can only go so far as it can stretch. So far that only means some coastlines and part of Bilgewater, but the Mist grows every passing year and Morde wants to spread it as far as he can so he can have vengeance on Maokai and finally be free again.

I imagine if the King found Maokai, he'd be most interested in consuming its life-force to make himself stronger, so he can have an easier time finding Evelynn. If Eve found Maokai, I'd imagine it might give her hope to fix the Shadow Isles, and would probably try to help him find a cure for undeath. That is, if she's capable of hoping at this point.
