Exar Kun

Exar Kun was a Dark Lord of the Sith who flourished thousands of years before Darth Sidious and his Sith apprentice Darth Maul. According to the Qel-Droma Epics, Kun was a former Jedi who turned to the dark side of the Force and became a Sith Lord, leading a Sith Empire with fellow fallen Jedi Ulic Qel-Droma around 4000 BBY. According to the Qel-Droma Epics, the double-bladed lightsaber design dated back to Exar Kun.

During the Imperial Era, crime lord Dryden Vos owned a desk with an obsidian slab as its base, which he had plundered from a Sith temple. The stone was carved with the warding spells, as well as an inscription reading "Our temple honouring Sith Lord Exar Kun."
