It is the way of the rock trolls to advance in rank by challenging those above them in combat. When you win, you get the rank of the defeated troll, and this process extends all the way to the top. It also means that when a troll is killed, those that remain may fight for the vacated position. It is within this system that newly named King Sybrik assumes power, and that bodes ill for Tryton. The former king saw potential in Tryton's new belief system for troll society, but Sybrik absolutely does not. In fact, Sybrik is so full of contempt for Tryton and his followers that he feels they have no place in troll society. Tryton knows he can beat most of his superiors in combat, but he also knows he cannot beat Sybrik. So it should be no surprise that shortly after Sybrik ascends to the throne, Tryton finds himself and his followers exiled from the only home he has ever known.
