Fayne is a wandering minstrel from Italy in the 17th century
Wandering minstrels were second rate to actual minstrels. They went from village to village looking for ANYONE who they could preform to and get paid. They were entertainers as well as musicians(Jester + minstrel = wandering minstrel) Fayne has an OCD thing where he’s a bit of a germaphobe and in turn tries to avoid performing in Inns and taverns. Also when there’s a large crowd he gets over excited and tends to have a habit of herding them as he moves about and entertains. His annoyingness is inspired from the minstrels in AC:Brotherhood that enjoy getting in your way all the time.
