This is thought to be some kind of alternative RPG. That is, there are no hero and no baddies. Or, to put it poetically: There is no evil but that which you bring with you. You can be whatever you want, from a film, comic, or literary character to a Tyrannosarus Rex or an amorphous blob.
Your bio is 'normal' in every term (that is e.g. your Luke Skywalker and busy slaying Stormtroopers)
and suddenly your on a forest clearing, with the others around.
I'll just GM on this one.
