Rufin, having grown up with parents who were outcast by their people, lived and survived only by his familys ability to provide.
The harsh enviorment of the outdoors has toughened him, lack of communication with others has left him with little curteous behavior, and a rather brash way of speaking his mind.
He never really understood why they were forced out, as it had occured before he was born, and it was not a topic much discussed. He did understand that something serious must have happened, for dwarves to turn on their kin.
He does know, that when he has met those who know who he is, they usually will turn away and never acknowledge his existence.
What could have been so bad for him to be punished for what his parents did? It doesn''''t matter anyway, Rufin needs no one.Rufin has his axe and his strong health, and he will do fine with those.
