[@Ambrosia]I'm not setting limits on length, though I don't expect a novel; what I [b]do[/b] expect, if it is of a shorter length, is greater quality and depth. 

These are outcast gods, with entire mythos' of their own readily available all over the web, and I'd be disappointed if there wasn't enough there for an imaginative mind to craft into something good.

So, the short answer is really as long as you like - or don't like - because length is not what it's about.

As for being busy, that's perfectly fine, I look forward to seeing what you come up with. I'm sure it'll be grand.
