I think it's interesting that they've cast the light on the shadow isle again, since we really haven't had much lore from there before. I'm interested to see where they go with this, and I'd love to hear more about Ebonmaw vs. Vilemaw, since dragons have been made to appear pretty badass in the LoL universe and as such, Vilemaw must be pretty ridiculous.
I am curious though, since it's a League-sanctioned battlefield, are Ebonmaw and Vilemaw just toned-down magical clones, like Baron Nashor on SR? Or was Ebonmaw a toned-down clone, and Vilemaw some beastly spider thing that found its way onto the battlefield without the League noticing and wiped-out the Ebonmaw clone, and was allowed to just stay there? Was Vilemaw the spider monster from Elise's lore, and as such, did she lead all those people to a League battlefield to be murdered? Or is Vilemaw a clone of the spider monster from her lore, which lives in an entirely different location on the shadow isles? SO MANY QUESTIONS.
