Lord Klarrn was a Knuckonian officer serving the Dragon Dracomancers guild on the Knuckonian homeworld. He opposed the Dragon Council's decision to go to war with the Eagle Alliance on the basis that there was not enough proof to accuse the Eagles of breaking the peace treaty. Klarrn was overruled, as the majority of the Council sided with Lord Sleacherling, and the Dragons went to war.
