There is nothing more important to Satsi than her twin brother, Uji. Period. She’ll do absolutely anything to keep the ex-Jedi alive, well, and happy; and if she failed, she’d tell whoever was digging his grave to dig two instead. While she will wear confidence, bravado, and charm as masks in public, she only shows her most vulnerable side with him.

Unlike most siblings, however, the twins have the Force in their shared blood and are connected by an inborn mental bond. They can sense one another when close, and glean impressions of condition at distances, though Satsi's inability to effectively wield the Force means she cannot shut these sometimes distracting impressions out. They are reactionary when together, sparking wild emotion, and yet it’s when they’re together that they’re steadiest, capable of perfect synchronicity. However, if separated unwillingly, Satsi will jeopardize all else until reunited with her twin.

Satsi lived and breathed for one thing over twenty straight years of her life: to serve her former lord, Jashin. His right hand in the Black Sun Cartel, Jashin molded her into an enforcer, thief, courtesan, and commander under the moniker the Demon's Doll.

Satsi was taught to assimilate with any level of society, from backwater gutters to senate ballrooms — and how to use her body however necessary to benefit the Cartel. She can bring someone to their knees with her voice, steal their secrets with her curves, and improvise and implement a convincing cover story with all the grace of a trained performer. Manipulating people — whether through seduction, violence, or crafted lies — is simultaneously a career and her chief method of interacting with the world around her. Among other things, this has made it difficult for her to form genuine connections with others, with rare exception.

Satsi's life, love, and drive all came from pain, and she's complicated in the way that everyone knows means ”psychotic witch." She is a proud, stubborn free-spirit at heart and it shows in her bad attitude, troublemaking tendencies, and sharp tongue. Most people apply the word “subtle” to Satsi only with sarcasm, but a few who know better will see other, wiser sides to her. She is often violent, vulgar, wild, gutter-rough, and all manner of hedonistic, reflected heavily in her natural speech and mannerisms. Simultaneously, she can also be thoughtful, clever, incredibly devoted, and graceful as a dancer. A very precious, beloved few will find headstrong compassion, generosity, and overprotectiveness from her; but most will likely be on the receiving end of a fake smile and mysteriously lighter pockets.

Most aptly, she's a shiny coin stained with dirt — there’s silver there, but it's hidden beneath a muddy surface.

Satsi has many faults, and she knows it. She’s ruthless, cruel, and painful. She’s weak at her core, codependent on other people she fixates on. She’s damaged goods, broken, either unwanted or easy to use. She knows it, but she isn’t ashamed or afraid of any of those things. For whatever else she is, she is brave.

She believes in being true to and proud of herself, in being unafraid to feel fear, and expects just as much from others — often resulting in her throwing the word “coward” around when people shy away from things. Deep down, Satsi is a lionhearted girl, and it shows just a bit in everything she says and does. She’s bold in every insult she recklessly yells, in every battle she faces down, and in every instance that she admits to being afraid while soldiering on, head held high, all the same.

Few things make Satsi feel more alive than promising to break somebody’s pretty frakkin’ teeth on the curb — and then following through, with a few punches besides. She doesn’t just like a good fight: she likes to start fights. She likes violence, pain, and getting down and dirty. Whenever Satsi fights, it’s never just for survival. There’s always that carnal, wild edge underneath her skin, burning up her blood along with the anger simmering below.

Satsi battles with her whole body, most notably with her fists and extensive martial arts training. She likes to feel the impact, feel things break and bend under her hands or under her skin, and as such doesn't prefer most ranged weaponry. Knives and pistols are deadly players in her repertoire, but most often, Satsi just charges headfirst, ready to throw that first punch and welcoming any hits coming her way as a result.

Satsi has no patience for Force-users, having spent all her life knowing that there were people like her and people like them. Satsi is at an inevitable, steep disadvantage against anyone wielding the Force. However, she’s survived this long, and knows that the best way to handle them is to play by her own rules.

Satsi has desperately devoted the last several years of her life to training to bring "sparkfingers" down to her level, studying how to spot them in crowds; prepare herself for their tricks and inhuman physical abilities; and even defend against and wield a lightsaber after practice with her twin. Accordingly, she relies on her tolerance for pain and feints and ploys to outlast, unbalance or otherwise unhinge her Force-fueled opponents before moving in quickly for the kill. She’s never needed any mystical mind powers to lay down a beating; but that’s not true for most Jedi.
