Biography
Daw Sembian was the father of Vil Sembian. Daw was a famous weaponsmith, who created a schematic for a new type of blaster which could tip the scales in the Galactic Civil War. Daw died some time prior to 1.5 ABY, but left the schematic for the blaster to his son. During 1.5 ABY, Vil Sembian headed to Anchorhead on Tatooine to deliver the schematics to his friend, a Rebel captain named Nitra Vendallan. However, the Empire was on his tail, so Nitra Vendallan sent a Rebel spacer to find Vil and bring him back safely to town. Despite facing resistance from Imperial forces, the spacer succeeded in escorting Vil. Vendallan was pleased, and saw to it that the schematics made it to Alliance High Command.
