In-game description
"When asked about his past, Valygar is silent for a long time and his face becomes grim. He explains briefly that he is is the last of the Corthale noble line, a family that was once one of the wealthiest in Amn. The Corthalas have always been cursed with magical ability, however, and Valygar spits the words with great derision. Every Corthale who has used their magical talents has become obsessed with them and ultimately come to a grievous end. His mother was the most recent victim, although the ranger does not elaborate on the point. Valygar intends to fulfill his family's oath ot find and destroy their ancestor, Lavok, and then he intends to let his cursed bloodline die out once and for all."
