@Riot, About Skin Lore...

Can you give us a list or something on the general idea of skin lore? Recently I saw a few Red Posts about Arclight lore, and how it's all about paladins that fight darkness and imbue themselves with power by Arclight Vel'Koz, and I thought that was just really really interesting and a shame we don't have any official write up of it like we do with Star Guardian. So Riot, can you give us a small hint at the very least of what the skin lore really is?

For instance, Eternum Cassiopeia is very interesting since we see a bit more of what Eternum actually are, since she mentions 'assimilation' a lot, along with the ability to corrupt organic lifeforms. Are there any other skins with lore that you haven't mentioned yet?
