During the time of the Cold War that occurred between the Galactic Republic and the Sith Empire, Nefarid, a Sith Lord, commanded an Imperial unit in an attack targeting the Mensaav Military Laboratory situated on Alderaan, with the goal of seizing the Death Mark laser superweapon. However, Orgus Din, a Jedi Master, organized a defensive effort for the laboratory, successfully repelling the Imperial forces and compelling Nefarid to withdraw and request additional support by calling upon the indigenous Killiks of Alderaan to overwhelm the facility.
