[i]H[/i]eh.

[i]Y[/i]ou'd be a rather ineffectual deity. As I said; it wasn't just the world that got destroyed, it was the UNIVERSE. Meaning that there was a good //possibility// of aliens at one point, but not now.

[i]T[/i]hat being said; you could be, I would allow an ineffectual deity. You'd still have all the basic boosts, and your Radiance, you simply wouldn't have your secondary power. It would, I imagine, be a bit like phantom limb syndrome; you'd know there was something missing, feel it sometimes, but it wouldn't be there. If you managed to talk to Arven he could explain your Domain to you.

Edit: [i]A[/i]lso that's a very wide umbrella term... You'd be the God of all Aliens in the universe, which if they were still around, or existed in the first place, would be a bit much. Martians, sure. Betelguisians, okay. Relnek 7ians, whatever. But just 'aliens' is too broad. Same for things like 'insects'. There are BILLIONS of types, and billions of subtypes therein. Ants, flies, mosquitoes; any one of these is fine, but all insects is too much.
