Daimanate Dynamic Testing Facility (Darkknell), also known as the Black Fang, was the main research facility of the Daimanate, located in Xakrea. There, the Sith Lord Daiman developed new war technology to combat his older brother Odion in their never-ending attempts to one-up one another in rival combat. This technology included the Convergence, which looked like a dark, lopsided pyramid and had few entrances which were all guarded.
