Lord Geist Weiss was an alchemist of the resurgent Sith Empire that eventually rose as Shadow Hand of the Dark Lord of the Sith, Darth Vereor. He was born on Empress Teta, hailing from the noble House of Weiss, one of the political rivals of the House of Es Cade, the royal bloodline. Before his Force sensitivity was recognized and acknowledged, the Cinnagaran nobleman spent a significant amount of time in the Sage Halls of Empress Teta, reading up on the Force, something that fascinated him. However, this fascination would eventually lead him on the path to the Sith.
