Motley Crue is finally complete, [@AdobeFlash] and [@Mr Allen J], if you're still running this game (and I hope you are). For the sake of backstory, I'm assuming what it describes are events prior to the premise of the game. 
[hider=Possibly spoilery stuff? I dunno, but let's not risk anything.]
I.e. each part of JJBA up to Stone Ocean runs as normal, and [i]then[/i] the game takes place.

If that's wrong, for the love of God tell me because it'll need changing if it's wrong. I've also got an idea for a Pillar Man if you'd like me to explain that, but whether I bring him into existence depends on whether players are allowed to run more than one character.
