Emarr Ottkreg was a human male colonel and loyalty officer for the Imperial Security Bureau who was stationed aboard the Imperial-class Star Destroyer Vigilance during the Battle of Endor in 4 ABY. Strongly disliked by the Vigilance's admiral, Rae Sloane, Ottkreg questioned her tactics as she gave orders during the battle while he personally watched the fighting on the Star Destroyer's holotank. Ottkreg greatly enjoyed watching the destruction of the Rebel Alliance on the hologram but began trying to give orders to the crew once the battle started turning against the Empire. Realizing the Empire had lost and that the Death Star II was going to be destroyed, Sloane shot and killed Ottkreg rather than arguing with him when she ordered a retreat.
