You really haven't been paying attention, have you, solari?
Traemlin wasn't chased out. It was just darn dunnera people following him. He won the duel against Belruel and then when Tiberius challenged him I remember a pretty irritated reaction towards Tiberius and he did not accept that one.
The reason he left, afaik, is to take up one of Thal's lordships in the colony. Not exactly chased out and look at the region he got...
