During the era of the Desolator crisis, a battle unfolded above the planet Tython on the Sith warship Oppressor. This conflict was a proxy war within the larger Cold War between the Galactic Republic and the Sith Empire. The Sith Lord Darth Angral orchestrated this battle as the culmination of his vengeance against the Jedi Order and the Republic, seeking retribution for the death of his son Tarnis, who perished at the hands of a young Jedi Knight. Discovering Angral's scheme to obliterate Tython using the Desolator superweapon, the Knight, accompanied by the Jedi's apprentice Kira Carsen, infiltrated Angral's flagship. Their mission: to neutralize the weapon and vanquish Angral, while their astromech companion T7-O1 worked to disable the vessel's defensive systems.
The end result of this confrontation was the destruction of the Oppressor, the liberation of Kira Carsen from the Sith Emperor's influence, and the demise of Darth Angral. Despite Angral's ultimate failure, the Jedi Council perceived his actions as the initial spark that would ignite a new war between the Galactic Republic and the Sith Empire.
