There don't seem to be a lot of details to work with, so I've gotta ask a few things before I post.

[b]1a[/b]: Humans, are they around? Are they involved in the war at all, either as things to be stepped on or some sort of controllable asset?
[indent][b]1b[/b]: If they're around, are there cities and the like scattered about?
[b]1c[/b]: What else is out there chillin' in the world? Are we to expect giant fire breathing dragons to just be flying around and shit, or is it more or less a realistic world with unrealistic super-deities?[/indent][b]2[/b]: Are there any currently unknown [i]"things"[/i] that we might need to know about? Divine metals? Super god-killing artifacts? Magical space libraries? Laser Sharks?
[b]3[/b]: Is this going to actually be a full-on war, or just a sort of [i]"We don't like eachother, and we sometimes have giant epic battles in the sky"[/i] kinda deal?
