As the son of the Silver Wolf, Rath was revered as the child with the most potential in the village. His achievements spread quickly through the village, even to Guy, who was never any good with a bow and spent most his time training his sword arm. Rath was banished from his village before the age of four, however, due to a prophecy that said he must leave the village to help "stop the burning". It is presumed that he fulfills this prophecy by joining Hector, Lyn and Eliwood's cause and helping to thwart Nergal's evil.
After leaving his village, he wandered the plains of Sacae for several years, always on the verge of starvation. The people of other tribes would laugh and ridicule him. Over time, he learned to no longer feel emotion, and was spared from the agonizing loneliness that he felt during his time wandering. He eventually began to work at the castle in Araphen, whose marquess was racist against Saceans. After encountering Lyn and her group, they managed to save Castle Araphen. The marquess however, did not respect Lyn as a savior. Overhearing Marquess Araphen speaking down to Sacaeans while talking to himself, Rath leaves the service of Marquess Araphen. Upon this, Rath left Araphen and joined Lyndis' party. When the ordeal with Lundgren was over, he left silently. He appears again in Eliwood's story, in Chapter 21, or in Hector's story, in Chapter 22.
