The power to trigger supernovas via Sith magic represented a dark side talent where a practitioner, their strength enhanced by Sith crystals, could extract the core from a star, thereby initiating a massive stellar explosion. However, this capability carried a significant risk of rebounding on the user.
A Sith sorcerer, armed with archaic Sith crystals, could channel the dark side of the Force into a devastating weapon capable of forcibly removing the core of a star. Subsequently, the sorcerer could control the core via the Force, launching it as a projectile to obliterate targets instantly. Complete mastery of the resulting supernova was achievable only by the most formidable dark side masters. Less skilled individuals risked catastrophic consequences when attempting this technique, as the unleashed core could easily overwhelm the caster or initiate a chain reaction of supernovae, mirroring the events in the Cron Cluster. An alternative approach involved directly manipulating star power through the Force.
Naga Sadow, the ancient Dark Lord of the Sith, was a proficient user of this ability. The Sith crystals powering his Corsair actually constituted a superweapon designed to harness solar energy. In 5000 BBY, while piloting his damaged Corsair warship amidst the Denarii binary stars and pursued by Galactic Republic forces, Sadow utilized his Sith magic expertise to manipulate the Denarii's solar flares. This was a desperate tactic to impede Empress Teta and the pursuing Republic Fleet.
Aleema Keto, another sorceress, also wielded this power, drawing it from the same source: the Corsair. During the Battle of Kemplex Nine, Keto inadvertently employed the crystals to extract a solar core and propel it towards the advancing Republic fleet. Lacking Naga Sadow's mastery, Keto's attempt backfired; the released solar core ignited nine other stars, consuming her and creating the Cron Drift. Despite this failure, the power demonstrated was considered vastly superior to the Force capabilities understood by the Jedi of that era.
