The primary research center for the Daimanate, known as the Black Fang or Daimanate Dynamic Testing Facility (Darkknell), was situated on Xakrea. It was at this location that Daiman, a Sith Lord, engineered innovative war instruments intended for use against his elder sibling, Odion, in their constant struggle to outdo each other through combative competition. An example of this technology was the Convergence, a vessel resembling an asymmetrical, shadowy pyramid with limited and heavily protected access points.
