Makes a lot of sense. Zed and Syndra come from the same state and have basically identical ideas and goals, I kind of expected them to team up all along.

Given Hecarim's lore and how will-less and one-dimensional he sounds in his quotes, it'd kind of make sense for him to be one of Mordekaiser's enslaved spirits... perhaps there was a war on the Shadow Isles, and the faction of Hecarim and the female altar ghost was crushed by Mordekaiser's?
