Darth Malak
this was the title adopted by the former Jedi Knight Malak, after he learned to wield the Dark Side of the Force from his friend and mentor, Revan. As they led the Sith forces into battle, Darth Revan and Darth Malak conquered a number of star systems before the Jedi Knights were able to launch a counterattack. In a bold move, the Jedi managed to trap the pair without the support of their troops, and Darth Revan was believed to have been killed in the struggle along with many Jedi Knights. History has hidden the exact details of the battle, and it was unclear whether Darth Revan was killed by the Jedi or by his own apprentice. Some historians believed that Malak was the stronger of the two Sith Lords, and either survived because he was stronger or smarter or more devious than Darth Revan. It was later discovered that Darth Revan had been captured by the Old Republic, and was given a memory wipe to remove any traces of his allegiance to the Sith. Regardless of the exact details, Darth Malak took up the mission of his former master and continued to wage war against the Old Republic. He was distinguished by the unusual face shield he wore, an apparatus that was required after he lost his lower jaw in a lightsaber battle. His speech was assisted by a vocabulator, and his voice had a distinctly metallic sound to it. Unlike the prior Sith forays led by Darth Revan against Republic systems, Darth Malak destroyed worlds rather than capturing them, ensuring that vital resources were no longer available to either side of the battle. In the tradition of the Sith, Darth Malak took Darth Bandon as his apprentice, and the pair worked from a base on Korriban for many years. His forces were believed to have been armed by Czerka Corporation, although such a link was never verified. It was eventually learned that much of his war machine was produced in the holds of the Star Forge, which he had usurped from the Rakata and modified to produce Sith Fighters and other weapons. Darth Malak powered the Star Forge with captive Jedi Knights, drawing on their powers to augment the massive input of the Unknown World's sun. With the defection of Admiral Saul Karath, Darth Malak acquired the Leviathan, which served as his personal flagship, and he appeared to be invincible. In an epic battle, the Jedi Knights and the forces of the Old Republic set out to destroy the Star Forge and eliminate the threat of Darth Malak. The battle waged for a long time, until Darth Malak was killed in battle and the Star Forge was destroyed.
