Organa Palace, also referred to as Castle Organa, was the ancient family seat and property of House Organa. It was situated along the Apalis Coast of the untouched planet Alderaan. Throughout the Cold War, it functioned as the Organas' operational center.
Aleyna Hark was stationed in the palace during this era. The Mirialan's loyalty to the Sith and their plan to seize the Death Mark initiative remained a secret. Consequently, a Jedi Knight received the assignment to eliminate the danger that the Death Mark presented.
