Here is a character players meet on Darth Malak's flagship, the Leviathan.
Saul Karath: a male Human born on Corellia. During the Mandalorian Wars, he was an admiral for the Galactic Republic's Navy.
As happened, when Karath thought the Jedi Padawan Zayne Carrick was a Mandalorian spy, Karath brought Carrick into custody on the flagship Arkanian Legacy.
Upon different circumstances, Karath played a role in the events of the Covenant Affair, where he helped destroy the Jedi Covenant: a secret Jedi organization dedicated to preventing the rise of the Sith. One of the leaders, the Sith acolyte Haazen, led an insurrection against the Jedi Order.
Little was said when Karath became Revan and Malak's subordinate. After the Mandalores were defeated, Karath stayed behind instead of follow the Jedi into the Unknown Regions, unknown even to a restorer.
Karath, as the Jedi Civil War enclosed, transferred his allegiance to Darth Revan's Sith Empire. He brought his flagship, the Leviathan, to Revan's service.
As a testament of loyalty, Karath killed many civilians on the planet Telos IV, earning him the wrath of his former friend and protégé Carth Onasi. It was Karath's own curse.
Right after Malak betrayed Revan, Karath continued his services under Darth Malak's command.
As the final year of the Jedi Civil War came, Karath ordered the Sith to blockade on the planet Taris, to search for Bastila Shan. Eventually, Karath was told to destroy the planet. The bounty hunter Calo Nord, having escaped the attack, informed Karath and Malak that Shan escaped with her companions. Karath and Malak told Nord to find Shan, but weren't aware this would be his final stand.
Time went on and Nord did not return. Malak, under Karath's eye, sent Darth Bandon in search of Shan and her companions. Bandon did not return either, causing Karath to capture the Ebon Hawk.
Hounding did not do any good, for Karath saw that Revan, Shan, and Onasi refused to report on their mission. Eventually, Karath ordered an attack on the Jedi and Onasi. In the heated firefight, Karath was badly injured. He told Onasi Revan's true identity as the former Dark Lord of the Sith, and then succumbed to the wounds given to him by Onasi and the Jedi. There was nothing to mock.
