Voidbringer Zilean

It could be a really interesting concept, especially as a legendary skin. With all the new attention the void is getting, it seems clear that a lot of his spells could conceivably use fancy/voidy particle effects (time bombs could become parasites, speed boosts could be accompanied by writhing masses, etc.).

I also feel like there's very little in the way of void-related supports, and Zilean's skin pool seems lacking.
