Well, full-blown AU isn't necessary, haha. Any small change from canon is enough to be accepted. But if you're getting another muse for the place, that's great! It'd be cool to see you and play there if nowhere else.
I know a friend of mine is looking for a Dean to play against her Cas in a slash line to take to a game. I'm looking for some people interested in a game centered on a war between gods who have chosen mortals and similar peoples to fight for them. I've also been looking for a small group PSL that's set in the SPN universe. The angel I've grab attached to playing needs a cozy, active home and I just haven't found good players for the most important roles.
