Oh well for my vision of this RP, there's a realm beyond ours and all the parallel dimensions linked to us, where all the really nasty Eldritch Abominations of the Cthulhu Mythos and the like reside. It's called a lot of things but Void can be applied to it. It's mentioned in the Codex and as I've been saying breaking into it is a Big Deal. 

I'd like everyone to put specifics for their powers yes as I've been saying.

EDIT: Archmage, The sheets are better and MCs powers can be readily explained but there's really no reason why Light can regenerate like that. And regeneration doesn't mean you wouldn't need to breathe or wouldn't be affected by toxins. You could just say it's part of some bizarre physiology but as of now there's nothing. Also I'm not sure why hitting specifically would increase her speed it seems like a videogame mechanic or something. And like I've been saying I'd prefer if the two of them were just from some bizarre magical world like the Fifth Dimension. (Narnia, Wonderland, Oz, and other magical lands actually exist in this universe) Biddz is right on the money when he saws Void is thrown around a lot.
