|Chronological and Political Information|
Jaeff was a Human male Admiral who served in the Imperial Navy during the First Galactic Civil War. Throughout the war, he was charge of defending the Corellian shipyards from any Rebel attack. Following the battle of Endor, Admiral Roek was recalled along with his task force to reinforce the system's defenses alongside Jaeff. It was unknown whether this action took place, however, since Admiral Roek's flagship came under the control of Grand Admiral Josef Grunger and soon afterward Corellia's defense was assigned to Grand Admiral Danetta Pitta.
