In the year 3960 BBY, Revan and Malak, who were Jedi Knights, pursued the Sith Emperor's path. This trail led them from Nathema to Dromund Kaas, which served as the capital for the True Sith Empire. They then began a mission lasting several months with the intention to assassinate the Emperor. By pretending to be mercenaries, the two Jedi successfully earned the trust of Yarri, an Imperial Guard. However, Yarri betrayed them, leading them into a snare where the Emperor dominated their wills. Converted to the dark side of the Force and given the titles of Darth Revan and Darth Malak, the newly appointed Dark Lords of the Sith received instructions to seek out the Star Forge and to wage war against the Galactic Republic. However, they soon escaped the Emperor's influence and chose to locate the Star Forge for their own purposes.
