The Palace of the Eternal Dragon resided on the planet Zakuul. In the course of the war waged against the Alliance, Empress Vaylin chose to host a party within its walls to commemorate her triumph, however, this celebration faced disruption when The Commander, aided by Theron Shan together with Lana Beniko, managed to breach its defenses.
Subsequently, the palace met its demise when Vaylin commanded the Eternal Fleet to unleash its firepower upon it, a desperate measure aimed at eliminating the Alliance Commander in addition to her sibling, Arcann, but it was unsuccessful. The aftermath was catastrophic, with her enemies and brother managing to evade destruction, numerous Zakuulans perishing, and substantial devastation inflicted upon the surrounding environment. Vaylin's reputation plummeted from one of dread to one of scorn in a remarkably short span. The respect of Zakuul and its populace was lost, and she shifted her focus to breaking free from a conditioning imposed by her father Valkorion, becoming more consumed with annihilating the Outlander than fulfilling her duties as Empress.
