I ended up making quite an expansive background for this, which I've nearly finished putting together. It will [i]definitely[/i] be going in the Advanced section considering how much detail will be put into it - but I suppose that's what happens when you come up with the idea of creating a game world that's a patchwork of different worlds and realities mingled together, and having to work out how they all fit together. 

Hopefully enough of you are still interested at this point to join in, and even if not; I'll still get the OOC up, as that seems to attract new players on its' own, regardless of an interest check. In fact, OOC's almost seem to attract [i]more[/i] than an Int-Check does.
