Hmm... I'm hesitant. But, and this is a big but, if you can prove that you can start out very small with few powers, and work your way up, then I'll allow it. If it becomes a big problem, we'll sort it out when we get there. Just... We can't have a whole lot of 'celestial' beings. So let's keep it a small number, yeah? 

If you can figure out another character/species idea you'd rather do, that'd be great but if you're dead set on this, I don't really see why not. I think the powers you have lain out are fairly balanced and not too terribly OP. So unless anyone has problems with it, I don't mind. Again, if there's a problem later on, we'll sort it out when we get there. For now, you're free to head on over to the thread and make a CS. :)
