Hmmmm, this sounds really cool, but not sure where to start..
Hey there! All the characters always start by suddenly waking up in a strange place -- I'd just write you into the scene and your character would discover things happening without knowing why he's there.
I think the princess will be accidentally summoning Keplo's character -- no reason why two of you shouldn't appear. :)
Or, you could start alone in the woods and find your way to the other characters. The same option stands for
@Keplo as well, if the two of you would rather start alone to orientate yourselves.
