Obviously, it would probably be something exclusive to Mages, given that the backstory is so intertwined, and it would be based on the choices you make early on (if you so decide to screw him over, I doubt he'd be very receptive to your advances later). As I was browsing the top files the other day, I came across the relatively recently added Ser Gilmore NPC/Relationship mod and thought, 'wouldn't it be great if someone could do this same thing for Jowan!?'. I've always felt like the mage was probably the most.(for lack of a better term) generic of the starting stories and it needed something more to spice it up.
