I heard you paid my old friend Fleet Admiral Dun a visit. I am sure he enjoyed it.
—Zevulon Vao to Nyax jal Sk'ar
Sha Dun was a Zabrak Fleet Admiral serving in the Imperial Navy of Darth Krayt's Galactic Empire. He was defeated and executed by General Nyax jal Sk'ar, a Kaleesh officer in the Imperial Army of the Empire-in-exile, while trying to defend the Minos Cluster. He wanted to surrender to the Fel loyalists, but Sk'ar executed him anyways. Before the Sith-Imperial War, he was friends with fellow admiral Zevulon Vao.
