Assault on the House Thul compound
During the era of the Cold War that pitted the Sith Empire against the Galactic Republic, a Jedi Knight in their youth assaulted a compound controlled by the Imperial-sympathizing House Thul, located in the Juran Mountains on Alderaan. The Jedi Knight, upon discovering that Aleyna Hark, the purported Republic researcher, was in reality an Imperial agent possessing the targeting mechanism for the Death Mark laser superweapon, hurried to save Duke Horis Thul. This rescue was necessary because Hark intended to use the stolen Republic superweapon to assassinate him and undermine the ongoing peace negotiations with House Organa.
