Norik Kun

Norik Kun was absolute ruler of the Sith Empire until early 14 ABY, when he was killed by Sion. His death threw the SE into chaos; later in that year, Rashael Koss re-unified it and took up the mantle of Dark Lord.

History
Kun was the primary student of Darth Kren, himself apprentice to a mysterious Sith calling himself Exar Sadow. After Kren's death, Kun took his Master's throne and ruled the Sith Empire as a dictator. Nevertheless, some - including his agent and deputy Iara Clane - considered him a more capable administrator. Kun was not aware of his Master's project, which produced Darth Sadis.

Kun took three official students, but his fourth, Tol Reban, was the only one to survive the Sith Empire's fall or achieve any prominence.
