I don't think Tristan would not be joining the Knights of the Round Table, He was brother of Ygraine Pendragon (née de Bois), Vivienne and Agravaine, the brother-in-law of Uther Pendragon, and the uncle of Arthur Pendragon, Morgana and Morgause. When his sister Ygraine died in childbirth, Tristan blamed Uther for her death and challenged him to a duel to the death. Uther won the duel but, before he died, Tristan swore that he would rise from the death and have his revenge. Tristan was reanimated as a wraith by the sorceress Nimueh in Series 1 in episode 9 'Excalibur'.
