Kenadias

Kenadias was a Human male Jedi Knight and later an Imperial agent. During the Clone Wars, Kenadias was initially stationed to help oversee security at the Jedi enclave on Nepsis VIII and later led a legion of clone troopers alongside the units of Jedi Master Rahm Kota, among other Jedi Generals, at the Battle of Viidaav. Kenadias managed to escape Order 66 and went into hiding on his homeworld for several years. He later changed his identity and managed to become a field agent for the Imperial Security Bureau, during which time he was sent on missions involving counterterrorism and espionage. When Kenadias' true identity as a Force-sensitive was revealed in his blood tests, he was brought before Emperor Palpatine, who instead of having him killed decided to have him retrained as a Dark Jedi. He spent the Galactic Civil War training, studying, and hunting down Jedi that served the Rebel Alliance with his new red-bladed lightsaber. He was severely injured during a duel with Rahm Kota - who he fought alongside in the Clone Wars - and had to have a respirator implanted in his lungs. After Palpatine's death in 4 ABY, Kenadias and a group of other Dark Jedi took a contingent of stormtroopers and a fleet of Star Destroyers and formed a military dictatorship on a sparsely populated snow planet on the inner edge of Wild Space, naming their government the Imperial Outlands Republic. The Imperial Outlanders' stormtroopers raided nearby planets controlled by other Imperial splinter factions and engaged in piracy in the surrounding sector. Many of the Dark Jedi that collectively ruled the Imperial Outlanders often identified themselves as Sith Lords and frequently journeyed on missions to worlds like Ziost and Korriban to acquire ancient Sith holocrons and Force-imbued war swords. Sometime around 12 ABY, a New Republic force led by members of the New Jedi Order attacked the snow world, killing hundreds of stormtroopers, all but one of the Dark Jedi (who later died trying to assassinate Luke Skywalker), and destroying every Star Destroyer present. The world's remaining population was relocated to refugee camps on Onderon.
