More specifically, it's the quest where you're first turned into a werewolf.

Sure, you have your rampage across Whiterun merrily slaughtering the guards/Heimskr/Nazeem/anyone else that annoys you... but when the screen turns black, what happened?

Whiterun to Gallows Rock is not a short distance. You were probably conscious and wolfed-out for most of it, because it's not too long after the transformation (or at least it never is for me) that you wake up outside Gallows Rock. But then that means you... what? Left the city for some reason? Were chased away? But what would chase away a newly-blooded werewolf confronted with an entire city they felt free to slaughter?

Anyone got any ideas?
