Riot, Kai'Sa is your chance to give us lore about the Void, don't let it go to waste.
It shouldn't be a surprise to anyone who has roamed the Boards for the past day that people have been in disagreement about Kai'Sa, be it "she looks broken" or her art style. I suppose I sit in the "Kind of like it but find myself at odds with it" group. Her design looks far too technological as opposed to biological, like a Void symbiote bodysuit should look like.
That being said, I'm not agaisnt the idea, but you need to give us proper information about how that came to be, which in turn could be explained with giving us more information about the Void itself.
For example, I find Vel'Koz to be quite an intriguing character, because he's probably one of the very few semblances that the Void isn't exclusively filled with monsters composed of 90% teeth and a nasty attitude, but there amount of lore he has is just laughable. I understand that the Void is supposed to be this spooky, mysterious place, but come on, it's long overdue.
Is she actually not Kassadin's daughter but a scientist who got caught in there? Is she Kass' daughter and got herself in a Samus-like situation with the Chozo? Or something that has nothing to do with these options? Give us something, anything, regarding her life back there, don't just fill her lore with what she does after she returns to Runeterra.
Give us Void lore, and something that explains why Kai'Sa's design looks like it came from Crysis, because saying "Void symbiote" isn't exactly cutting it.
