Kya Xivos, the current Sentinel of The Unity and servant to Azuro Kassan, has quite a lengthy and somewhat sad story.
She was born on the smuggler planet of Atzeri as the daughter of an infamous pirate lord named Margas Xivos.
Her mother happened to be the favorite concubine of Margas, and Margas himself did not particularly want a child at all, much less a daughter.
Nevertheless, he and Kya's mother raised the girl as best they could. Unfortunately though, Kya's mother passed away when Kya was 15, which left her without a female figure in her life.
For the next five years of her life, Kya remained under the thumb of her father, Margas, who taught her how to fire a blaster, fight with her fists, and talk her way out of potentially dangerous and deadly situations.
She would go on to be an excellent shot and very capable in melee combat, and she also grew quite the silver tongue as well.
By this point, Margas had warmed up to the idea of having a daughter, and grew to love her as his greatest treasure, even with the towering criminal empire he had built on Atzeri.
For the next two years Kya aided her father in his "business endeavors" by arranging meetings and cutting deals, buying off local politicians and security officials, and intimidating competitors.
Everything seemed to be perfect for her, until a single unfortunate incident completely destroyed her whole world.
She and her father, Margas, were conducting an attack on a spice freighter, however, it turned out to be a trap set by local police forces.
The fighting was chaotic, and amidst it over half of Margas's crew was killed, and Margas himself was fatally wounded and died during the escape.
Shortly thereafter, Kya's position as new head of the pirate clan was usurped from her by a traitorous former lieutenant of her father.
All of Kya's supporters were killed and she barely escaped with her life.
After that, she spent the next 6 years traveling the galaxy, alternating between smuggler and bounty hunter work, and by doing so, she established quite a few powerful connections in the criminal underworld.
Two years later, she would meet none other than Azuro Kassan, who somehow convinced her to cast aside her life as a criminal and bounty hunter and join his newly formed order of Dark Siders.
For twenty years, he trained her in the Jedi arts and the ways of the Dark Side, alongside the many young pupils she had helped him procure.
While a master swordswoman, her connection to the Force is somewhat shaky and untempered, making her aresenal of Force powers very basic and simple, which forces her to rely heavily on refined skill and raw talent alike.
While not nearly as stone faced as Azuro Kassan, Kya has a very serious personality and no tolerance for foolishness or idiocy. She has a strong admiration for Azuro Kassan and follows his teachings fanatically, and holds what is practically blind loyalty to him.
Interestingly enough, despite her young appearance, Kya is 50 years old. How she maintains such a young looking physical appearance is a curious mystery.
