He was killed by King Roaz of Glois, who seized his land and drove his family into exile. Larís ghost, sometimes in the form of a beast, wandered Korntin for ten years, until Wigalois arrived to destroy Roaz whom besieged Amene. Lar guided Wigalois through Korntin and told him of a horrible dragon named Pfetan that needed to be vanquished. Lar provided Wigalois with a magic lance to accomplish this feat.
Lar also revealed that Gawain was Wigaloisís father. Wigalois eventually avenged Larís death and allowed his spirit to rest.
