Captain Seku was the alias used by Dia Passik while posing as a member of the Hawk-bat Independent Space Force with other members of Wraith Squadron. Seku was a ruthless Twi'lek female, and it was in this persona that the already emotionally unstable Dia was forced to desecrate the body of fellow Wraith Castin Donn, who had been found by Zsinj's forces about the Iron Fist and killed. Zsinj and General Melvar had his body brought to their ersatz bridge and asked General Kargin to "kill" the "unconscious" intruder; Dia, realizing faster than her commander, "Face" Loran, that Castin was already dead, volunteered for the job instead, but became severely upset about it later.
