The consciousness of Vivackus Kavon di Plagia had been transferred from his dying human body into a Miraluka by Lord Esoteric. Because of the differences between the two races, Vivackus Kavon di Plagia is struggling to adapt to the unique way that Miraluka view the world. It will often take him a split second longer to recognize exactly what he's sensing, and he has difficulty making out individuals in crowds. The constant effort of learning to see entirely through the Force is a source of significant mental fatigue. Vivackus Kavon di Plagia can't operate effectively for prolonged periods of time without rest. Despite the drawbacks, Vivackus Kavon di Plagia has adopted an almost childlike curiosity at the new way of experiencing things.

As a true Sith, Vivackus Kavon di Plagia values power above all else. Vivackus Kavon di Plagia believes that control over people is both the chief goal and the purest form of power. Control over people is most efficiently derived from understanding of their motivations and goals. To this end, Vivackus Kavon di Plagia puts a great premium on such knowledge, especially when it comes to the other members of the Dark Brotherhood.

Vivackus Kavon di Plagia's brush with death and subsequent 'rebirth' as a Miraluka was extremely traumatic. While he retains all of his memories, Vivackus Kavon di Plagia often gets 'flashbacks' of memories from the person whose life he stole, leading him to question who he really is. He has developed a mild case of body dysmorphic disorder because his new body doesn't 'fit' quite right. The more stress he is under, the more tenuous his grip on reality becomes.

Unless absolutely necessary, Vivackus Kavon di Plagia does not dress like a Sith. In most situations, he doesn't act like one either. His relaxed demeanor, complemented with his average build and light frame is not naturally intimidating. Vivackus Kavon di Plagia finds such deceptions useful both in and out of combat. To the overconfident, he is seen as less of a threat, and thus has the element of surprise if things get dicey. To the naive, he can get what he needs without the use of force, and does not need to reveal his true nature. Those who see through the ruse are the ones Vivackus Kavon di Plagia knows he needs to treat seriously.

Through careful study and dedication to isolated martial-combat, Vivackus Kavon di Plagia has turned the act of dueling into an art form. A keen eye and attention to detail allows him the ability to learn their opponent's idiosyncrasies while fighting. Vivackus Kavon di Plagia then uses his own skills to capitalize on the opponent's weakness. Because of this calculated approach to isolated duels, Vivackus Kavon di Plagia has a harder time taking on multiple opponents at once at higher skill levels.

Vivackus Kavon di Plagia prefers to attack a mental or emotional weakness, rather than a physical one. Through use of the Force and emotional manipulation, Vivackus Kavon di Plagia will strike at his opponent's resolve. The actual swing of the lightsaber is just a formality. As a result, Vivackus Kavon di Plagia is very vocal in combat, constantly trying to unsettle, distract, or annoy his opponent.
