Sak'anto'nussos (core name Kanton) was a male Chiss officer of the Royal Navy of the Golden Empire. Several of his commanding officers considered him a tactical expert, and by the relatively young age of forty-four, he was captain of the Imperial Star Destroyer Assassin, under the overall command of Executor Breek Zagrev. In 154 ABY, the Chiss Centurion Vos'elk'eetash was installed aboard the Assassin, among other reasons, to learn from Captain Sak'anto'nussos's military knowledge.
