In 3667 BBY , Shan traveled to the Core World of Alderaan to investigate rumors that one of the planet's royal houses was harboring Imperial spies . However, the Empire invaded Alderaan while she was there,  and Shan raced to the royal palace in order to protect Queen Silara Panteer , though the structure was in ruins by the time she got there.  It was then that Shan had a vision showing her that Jace Malcom  —whose unit , Havoc Squad , was training injured troopers on Alderaan at the time  —would need reinforcements. Shan and Malcom had worked together on previous missions, and the soldier had tried to pursue a relationship with her, though she refrained from doing so because of the Order's restrictions on attachments. Sending word to the Jedi Council,  Shan rushed to the Juran Mountains to aid them in their guerrilla war against the Imperial forces marching on Castle Organa .  The Imperials were led by Darth Malgus, the Sith whom Shan had fought on Korriban fourteen years earlier, and by the time she arrived, the members of Havoc Squad were fighting a losing battle against a disorganized but far larger Imperial force.
