Rasilvenaira did not choose the life of an assassin, but at a young age she was forced into it by necessity. It sculpted a keen and calculating mind in her as she fought to survive her youth; she can now quickly analyze and adapt to situations and unforeseen complications in her plans as they arise. Her fight for survival fostered a ‘them’ or ‘me’ mentality that drives her actions. Rasilvenaira attempts to manipulate events towards her desired conclusion. She can sometimes lose focus of the 'larger picture' when in relentless pursuit of a target. And, as a pragmatic individual, she will not hesitate to eliminate those who get in her way - innocent or not - if it means achieving her goal. This ruthlessness leads others to be distrustful of her actions and motives.

Rasilvenaira has spent decades roaming the galaxy. Alone. She never formed solid roots to the places or people she has met. She deals with people more out of necessity than any desire for a 'connection' for companionship or social interaction. There are exceptions to this, but they are very rare. She has, however, become quite adept at forming bonds with animals and droids - often preferring their company over people. Calling her antisocial would be regarded as a compliment. Due to her affinity for these creatures and machines, she can often turn them towards her advantage. Unfortunately, her lack of desire to socialize with people often creates situations where she must rely on other means to accomplish her goals.

Forged as an assassin and sharpened by the teachings of the Sith, Rasilvenaira has become cold and ruthless. She keeps people at arm’s length, not allowing anyone to get close enough to become attached to. For her, it is ‘strictly business’ and she leads a life of perfect solitude. Her loneliness can manifest itself in critical assessments of others, mistrust of others' intentions, and even lead to paranoia of the unknown elements in a plan where multiple people are involved. This can lead to friction with authority figures. However, for the few individuals she has deemed trustworthy, she will walk through the fires of hell. She will become the shadow of death incarnate, unleashing the Dark Side of the Force at her full potential to ensure her victory - utilizing the many years of training she has received from the Brotherhood.

Rasilvenaira is frequently known for her sarcastic tendencies, especially when she's in a situation where she knows she has the upper hand. She also excels at walking the razor's edge of rules and will push the boundary whenever she has the opportunity. She tends to be far more critical of those in positions of authority than most of her peers, which tends to paint her as a troublemaker. She's fine with that, and will use it to her advantage if possible. While she is fiercely loyal to her Clan and those few people she truly cares for, she's far beyond the stage of blindly following orders for order's sake. She will question and consider the orders she receives carefully and will challenge them if she feels it's necessary.

Unlike most Sith, Rasilvenaira is not one for idle boasting or taunting when in combat. She prefers to remain quiet and simply observe her opponents. However, she isn't above making one or two small shots at an opponent whom she feels is wasting her time. She may also engage in more banter when sparring with someone she's familiar with.  But as a general rule she prefers to let her opponents talk to themselves and typically won't let herself be baited by taunts or insults directed toward her. She also prefers to use stealth to get in close for a swift and silent ambush rather than full on open combat.  In the event she finds herself at a disadvantage she will attempt to survive long enough to reclaim an advantage or find an escape route and live to fight another day.

Rasilvenaira knows that even a rancor can be brought low by a smaller opponent with enough successful attacks. This is vital, because she is aware of her diminutive stature and limitations in physical combat. She has honed her strategy - utilizing her smaller size and lean build - to extend battles where she can bring her quick wits, Force abilities, and combat experience to bear in leveling a battle against a stronger, or larger, opponent. She will attempt to stay at range, observing her foe’s tendencies and searching for weak spots to exploit. She is not above using ‘cheap shots’ or unorthodox tactics to whittle away at an opponent’s resolve and endurance until she can strike - swiftly and with maximum impact. Her patience in seeking ‘perfect’ opportunities can translate to moments of hesitation that can allow an opponent to close the distance and overwhelm her with more physical assaults.
