This commander held command of the Tyranny, an Imperial I-class Star Destroyer, throughout the Galactic Civil War, specifically during the Space Battle at Kuat. His refusal to provide reinforcements to the shipyards during the conflict, due to directives to remain at Fresia, marked his involvement. Subsequent to the facility's destruction, he appeared at Kuat in response to Emergency Code Zero, but he cautioned the Comm Officer that frivolous use of this Code would result in consequences from Vader.
