Kiaj spent her entire life as many of her warlike species do: a professional slaver. She, specifically, however, found a penchant for and pursued a career in disciplining the livestock. Kiaj is a torturer and interrogator, and her days consisted of grinding spirits into dust, tormenting and terrorizing slaves into submission, and ruthlessly and cruelly taking apart any enemies of the Empire; from the inside or out. Unruly slaves, traitors, criminals, and political rivals, and outspoken citizens alike all found themselves under Kiaj's care, and she prides herself in her work — to the point that she could be called a workaholic. Kiaj has trouble ever letting an interrogation end, always looking at the world through said lense, as if everyone she meets has something to hide from her that they must be punished for. This makes her somewhat paranoid, and ostracized except for to employers or her superiors.

Kiaj Siff would die for her Empire...the Zygerrian Empire, that is. Raised as one of its loyal members with their victory or death dogma and having spent her life not only walking on the backs of slaves, but breaking them, she is very confident, self-assured, and convinced of her own superiority. In Kiaj's eyes, all other species are weak, and other peoples' only use are either as toys for her amusement and comfort or for the service of her Empress or Emperor. Unfortunately for Kiaj, she was caught taking human cargo back to Zygerrian space, and subsequently imprisoned. Now, her only ambition is to gather enough of a bounty — in goods and people — to bring back to her countrymen and reclaim her good name, damn the rest. Far from her home, Kiaj is very alone save for her pets of both animal and sentient nature

Quite an optimistic individual, Kiaj tends to take anything life throws at her as a challenge and take setbacks as just obstacles to be overcome...overcome, smashed into the ground, obliterated, with their families purged and their land salted and burned... Her "victory!" attitude, largely influenced by her people's culture, tends to carry her through thick and thin, and even at her lowest, Kiaj is always intending to claw her way back up again. In her opinion, adversity just makes people stronger, and she intends to be as strong as possible for Zygerria, herself, and her so-called admirers. Of course, Kiaj's optimism can at times border on willful ignorance in admitting defeat that only lands her in deeper and deeper trouble, and her tendency for extremes and egotism can mean wasting wiser opportunities for the sake of her own sense of self righteousness.

Kiaj is a happy, affectionate person, kind and friendly to anyone who meets her. She will go out of her way to be nice to others, learn their name, their interests, their life stories, all the while being as sweet to them as possible, usually with very openly expressed adoration and nicknames. Until she isn't so nice anymore. If shown even the slightest hint of rejection or resistence to her wants, Kiaj responds violently, breaking things, lashing out, and screaming all manner of venom. Under all her sugariness is a high-strung, unchecked sadism paired with a deep-seated need to be loved and worshipped, and when she's feeling spurned, jealous, or at all improperly respected by those she sees as lessers, Kiaj becomes obsessed with inflicting as much pain and misery on her new enemies as possible, emotional, mental and physical, even if she must wait years to do so.

All her life Kiaj has wielded the master's whip, and though her skills are most suited to torture and maiming, she is not without the ability to fight if she must for short periods. The Zygerrian uses a combination of poisoned whip and blade to battle, even carrying a weapon that can be converted to either, and is masterful with them at mid-range. Closer and longer range engagements become more difficult, as her whip becomes ineffective in tighter quarters and she has no ability or defense against long-ranged weapons. Additionally, the same tendencies that make for a good interrogator make for a poor soldier; Kiaj tends to play with her food, and habitually keeps her attacks nonlethal, meant to inflict pain rather than end a fight. No warrior, she will be tired quickly and easily overwhelmed by better fighters or groups.

Kiaj didn't just use her "behavioral conditioning" skills on people — she also trained animals for service like intimidation and hunting. Despite being a master of the whip, Kiaj views creatures much more favorably than the sentient chattel of slaves, and while she is strict as a trainer, she absolutely adores the beasts she works with. She keeps several with her when she travels as company and protection, and can command one of her trained companions to take a bite or two out of a victim or just leave the threat menacing. In particular, she favors the native Zygerrian Brezak, and feeding her carnivorous reptavian bits of her enemies. Should her companion be hurt or killed, however, Kiaj is devastated and vengeful, and could lose all sense or control of a situation. Threats to her animals or inhospitable environments for them also leave her wary and exposed.
