Sapagos Vydrek was a male Chagrian who worked as an ambassador for the Fel Empire, and became the Grand Vizier of the new Galactic Empire of Darth Krayt. A cunning and manipulative man, Vydrek was a considered to be a skilled politician as well as a diplomat. He possessed very little loyalty to those who he worked for—Emperor Roan Fel, and later Darth Krayt. Instead, Vydrek was ambitious and more interested in his own power than serving others. These qualities were considered useful by the One Sith Order, which was why they named him the Grand Vizier after Dallis Eregin, the first one, was executed for treason.
