I disagree on Mordekaiser being the Ruined King (Question yourself: "Why he would have a sword that, in-game, is physical damage source against highly defensive targets, and related with someone that, in-game, is a tanky mage?), and I think is unnecessary to make Kalista a Rakkor warrior, with her being too close to the King to know him is more than enough, but must agree that Hecarim was her killer, just that you focus too much on making Hecarim look like a hero, when his site shrouded on the fog along with the other champion hints that, by all means, he betrayed someone, likely Kalista, and was everything except a hero.

And just making the King someone searching for power for himself sounds too boring and used from the common axis, aswell as making Hecarim have amnesia just for the sake of it like a cheap move, and also making the current state of Mordekaiser some sort of Xerath wannabe (freed from his body, his own prison) something repetitive.

But most importantly, you didn't gave answers for some plot-holes within you theory, such as why the Black Mist exists, why Vilemaw and Hecarim are what they currently are, what relationship had the unnamed isles with the Mt. Targon, or what had Maokai to do on these events beside seeing with impotence how all life perished from his lands.
