Born from a joygirl's passionate night with a passing nobleman, the girl who would become Dia swore that she would never follow in her mother's "line of work" kill the bastard that fathered her. At the tender age of eight, she ran away from the bar her mother worked in, only taking with her three thrones and a knife, and within two days, had killed someone in the capital's back alleys. A passing gang of smugglers witnessed the act, and, impressed with her ferocity and will to live, recruited her into their ranks as a pet project of theirs. With little choice but to accept, Dia spat on the corpse of her would-be violator and stepped forward into a life of organized crime and acceptable heresies.
Years passed, and the scared little girl grew into a fierce woman that no sane man in the underhive wanted to frak with if he wanted to keep his nads intact. In that time, Dia's done it all: smuggle civvies off-world, distill moonshine amnesac in the windowsill, clash with local gangs and Arbites (and live to tell the tale) and contribute to the spread of the Imperial Truth by killing feral mutants in the bowls of the city. Had she continued this way of living, it is most likely that she would have ended up dead in the aftermath of a deadly shoot-out, despite all of her luck. But when the opportunity to kill her father presented itself to her, she couldn't resist its siren call.
However, her vengeance came at a terrible price. Though she had succeeded in her goal (though means non-heretical but still horrible enough that I can't describe them here), all of her gang had been massacred by Arbites when a traitor lured them into their den while she was away. On that night, Dia had the choice to turn back and investigate as to where the Arbites were going, but she chose to ignore them, believing them to be capable of taking care of themselves. It was only when she returned to find the Arbites piling her friends together for a mass incineration did she realize the depths of her mistake.
Driven mad by rage and grief, her reckless hunt for the traitor enabled local agents of the Administratum to locate her and arrest her for the death of her noble father. Imprisoned and awaiting execution without trial, it was in the depths of the Arbites holding cells that she came into contact with Alistair Sharben, self-proclaimed Inquisitor of the Ordo Hereticus (with rosario to boot!). He offered her a chance to escape, to have her crimes pardoned if she could pass a simple test. Again, with little choice, she accepted, if only to escape the impending public execution and live another day. Those were all the words Sharben needed to use his authority to release Dia and spirit her away to the Inquisitorial proving grounds, where she would be tested as to whether or not she was acolyte material.
As it stands, Dia carries both the guilt for her friend's deaths, the nightmares of killing her father, and a burning vengeance for the one who betrayed them. All of these feelings lay hidden underneath a cold and hostile exterior. She doesn't know when she'll get to stick her shiv deep inside of his entrails, but this new opportunity as the lackey of Inquisitor Sharben should give her the access to the resources necessary track him down. And when she does, you can bet every last throne in your pocket that Dia's going to be the one doing the stabbing.
