The Sith Academy of Umbara was established by the Brotherhood of Darkness near the end of the New Sith Wars. They used it to train Sith assassins and spies, Warriors including Umbaran shadow spies. These initiates had a greater aptitude in the Force than their brethren in the academies. Here recruits learned to use the dark side for secrecy, deception, and manipulation, and other uses. Those who survived the rigorous training became deadly assassins or powrful warriors, preferring use of the dark side to kill rather than with physical force.
