Kavos was a Sith Lord of the male persuasion, who was an active participant during the Cold War era. This conflict was fought between the Galactic Republic and the reconstituted Sith Empire.
On Brentaal IV, Lord Kavos, acting alone, annihilated a Republic outpost, slaughtering every person stationed there. In a simultaneous battle, he killed two Jedi Knights, named Ayesho and Nil, without sustaining any injuries himself. These actions resulted in widespread recognition, and he became a celebrated figure among the Empire's populace.
An advertisement for his lieutenant was put out by Kavos; this message was intercepted by M1-4X. On the desert world of Tatooine, M1-4X infiltrated the group of fourteen hopefuls who sought to gain Kavos' favor, and added himself to their number. Kavos decided that a fight to the death would decide who would be his champion, and M1-4X joined the contest. M1-4X picked up a Nikto thug who was using a flamethrower and threw him at Lord Kavos, causing the Sith's robes to catch fire, and thus distracting him. M1-4X then targeted a Mandalorian who was using a jetpack, and as soon as his direction and speed were aligned, Forex opened fire, sending him hurtling toward Kavos and the Nikto. All three died in the ensuing explosion. The remaining candidates were being targeted by the Republic Strategic Information Service, and M1-4X eliminated them.
