Kalluux

Kalluux was a human male who ruled as Emperor of the Sith Empire during the First Age of the Old Republic. He was notable as the first Sith leader to defeat the Jedi, ushering in an era of Sith Dominion over the civilised galaxy.

Born in 3071 BBY, Kalluux inherited the throne of the Sith Empire when his father, Anaxun, passed away during the Siege of Korriban and the Sith Genocide. Determined to live up to his father's legacy, Kalluux orchestrated a plan to break the siege which cumulated in 3036 BBY when the Sith Armada, secretly under construction in the Unknown Regions, destroyed the Republic blockade.

Several years later, after amassing more power to his control, Kalluux declared war on the Republic in 3030 BBY, beginning his master plan to seize control of the galaxy from the Republic. After only six years of war, Kalluux's Empire had successfully invaded the Core Worlds and captured the Republic capital of Coruscant, beginning an era of dominance and expansion for the Sith across the known galaxy.
