During the conflict known as the Clone Wars, Leh'ahnyo Vas was apprenticed to a Jedi Knight who acted as their master. This master, clad in brown robes, fought with dual blue lightsabers. Together with their Padawan, Leh'ahnyo Vas, the master commanded a unit within the ranks of the Grand Army of the Republic. On one occasion, this unit intervened to rescue the inhabitants of a farming village from the attacking forces of the Separatist alliance, with the Jedi leaping into the fray directly from a gunship.
This master character is first seen in the initial narrative of Rise of the Separatists, a 2019 roleplaying game supplement published by Fantasy Flight Games.
