Oscar Schomburg was an officer in the Republic and Imperial Navies during and after the Clone Wars. In 19 BBY, he commanded the Wurrfler , an Imperator class Star Destroyer, and shortly after the end of the Clone Wars, it was used to intercept the Bantu Wind after it left the Tanis system with the Jedi Covenant Holocron.
The captain stayed aboard his submarine and was not involved in the apprehension of the holocron or Marion Ravenwood, leaving that task to Colonel Dietrich and René Belloq. When the U-boat arrived at Geheimhaven Station, Schomburg was seen in the docking bay as Belloq, Dietrich, and Toht disembarked.
Recieving a promotion to Admiral, and later Moff, Schomburg was transferred off the Wurrfler,and became one of the many Imperial officers stationed at the Death Star, supervising the construction of the superlaser. He was killed when the Death Star was destroyed by Luke Skywalker.
