Rumors were told that Hadra had ascended to her position of Dark Lord of the Sith by an affair with fellow Sith Lord Darth Malgus. However, these rumors were later proven false; as she had simply murdered her opponents and enemies to achieve her position.
Hadra presided over the Empire's capital world of Dromund Kaas in addition to the Sphere of Technology; one of the twelve Spheres of Influence that were each controlled by a member of the Dark Council. Darth Hadra gained her seat on the Dark Council after a Republic Strategic Information Service operation resulted in the disappearance of Darth Mekhis; a rival of Hadra.
When her forces discovered an ancient Sith shrine near Kaas City, Hadra attempted to claim it as her own territory. However, Darth Arctis, the current leader of the Sphere of Ancient Knowledge, protested her claims and became embroiled in a conflict with Hadra.
During the Republic bid to retake Corellia, she was sent to the planet to assist Council member Darth Decimus in the battle and was stationed into the holdout room. Hadra was later confronted by the Jedi and, after engaging them in combat, was eventually defeated and killed.
