When Captain Oklart and Colonel Trill were approached by the Emperor's Wrath who demanded the whereabout of Sith Lord Melicoste, Trill attempted to withhold that information, but Oklart felt it was need to assist the Sith in any way possible and revealed Melicoste's destination. Trill felt that would be equal to condemning fellow soldiers to deaths and accused Oklart of treason. The Emperor's Wrath killed her to stop her from calling Darth Baras.
