Dromund Kaas operation

The Dromund Kaas operation was a covert mission carried out by the Galactic Republic and the Jedi Order in 3640 BBY, during the Galactic War against the Sith Empire, that saw the Republic Navy attack the Imperial capital planet of Dromund Kaas. The naval assault was but a diversion—while Jedi Grand Master Satele Shan led the Republic Navy in engaging the Imperial First Defense Fleet, a small unit led by the Jedi Knight known as the Hero of Tython infiltrated Dromund Kaas with the purpose of confronting the Sith Emperor. The Hero had foiled the Emperor's recent attempts to massacre thousands on the planets Belsavis, Voss, and Corellia, a sacrifice that was necessary to start the Sith ruler's dark side ritual to consume all life in the galaxy, and the Jedi hoped to kill the Emperor before he could complete his plans.

The Hero and a small group of allies fought their way through the Imperial capital of Kaas City and stole the Sith Emperor's shuttle, in which they flew to the nearby Dark Temple. At the temple, they battled their way through the Sith and Imperial Guardsmen who protected the Emperor. The Hero's allies engaged the temple's defenders while the Knight and the astromech droid T7-O1 fought the Emperor in the heart of the temple. The Emperor was struck down in battle with the Knight, and although only the host body for the Emperor's immortal essence was slain, the Jedi and the galaxy at large believed him to be dead. The Sith Lord Darth Malgus, long at odds with many of the Empire's policies, claimed the Emperor's Fortress and declared a New Empire, and the six powerful Sith known as the Dread Masters decided that they would claim the galaxy for themselves. Although rumors of his death spread, the Empire and the Republic officially kept the Emperor's death a secret until the aftermath of the invasion of the planet Makeb two years later, when Republic Supreme Chancellor Leontyne Saresh publicly revealed the success of the classified operation.
