Darth Ouzal was a male Sith Lord of the resurgent Sith Empire, sometimes consulted by members of the Dark Council for his vast knowledge about Holocrons and Sith artifacts. At somepoint during the war against the Galactic Republic, Ouzal tried to duplicate the informations contained in a Sith holocron into the brain of two prisoners of war, Felix Iresso and Milo Pellam. The experiment of the Sith Lord was a success as Iresso had locked in a corner of his brain a library of Sith knowledge, but Pellam became mad.
