The Sphere of Technology, also known as the Ministry of Technology and the Pyramid of Technology, was one of twelve Spheres of Influence of the Sith Empire. Headed by a Dark Councilor, the Pyramid was responsible for the scientific advancement of the Empire and shared joint control of the Imperial Science Bureau with the Sphere of Biotic Science. After Darth Mekhis' death, Darth Hadra took her place at the head of the Pyramid and presided over the capital world of Dromund Kaas. After her death at the Battle of Corellia, she was replaced by Darth Acina.
