Age:26
Female
Appearance: Catherine stands at 5'7", with a slim, athletic build that is covered by her large nun's habit.

Something like this
Personality: Catherine is a solemn, but caring woman who is very protective of her charges. She is very cynical, despite her young age, yet still acts with hints of naivete due to her upbringing. As well, Catherine is highly distrustful of the Church, but stays within the organization to care for the orphans. As well, her beliefs often conflict with mainstream Catholicism, due to her Executor training.
Skills: Executor training, recon, spying, and assassination, Knowledge of the occult.
Abilities: Catherine is at peak human physique, as well as being highly intelligent. Her abilities with the Black Keys are very exceptional. Kirei Kotomine had the ability to throw a singular black key in 0.3 seconds, and four in 0.7 seconds. In comparison, Catherine can throw a single blade in .42 seconds, and three in .81 seconds. Despite being crippled, she can hold her own against most normal humans, and can use her training as a spy to discreetly watch and inform her Servant of the stats of the other servant. As well, with her knowledge she gained in her training, as well as her training in the occult and supernatural, she is well informed of possible players and has a reasonable grasp of possible Servants once given enough information. Her Circuits are unnatural, and using them is painful for her, as they had been transplanted by the Dead Apostle after she had blacked out. Sacrificing her legs, and the souls of her mentor and Gertrude, the Dead Apostle gave her enough circuits to give her slightly more than average amount of magic energy, with 40 units of magic energy. (In comparison Shirou had 20-30 units, Rin 500 units with a max of 1000, same for Sakura) With that amount of energy, Cathrerine would be able to provide comfortably for Servants with Mana ranks of B or lower, though at B she will begin to feel strain in doing so.
Catherine was born in France to a one night stand in the Parisian red light district. Her father took her in after her mother died in childbirth. She was chosen at the age of sixteen to become a Executor after she murdered her father, a heretic magus who had been draining the suburb they had lived in to increase his own powers, with a kitchen knife. Five years of training saw the girl grow to be an exceptional candidate, and her future would have been secure had it not been for one mistake. During her training, Catherine started a friendship with another trainee, Gertrude Baptiste. They were cordial rivals and, according to hearsay and rumors, lovers. They graduated together, and even apprenticed under the same mentor before the event.
Catherine's fall occurred during her first mission, a hunt for a Vampire that had been terrorizing a remote village in the Pyrenees. It was supposed to be a simple investigate and purge, except the mission went horribly as soon as Catherine, Gertrude and their mentor stepped foot into the village. The Dead Apostle refused to show itself, taunting the group, and sending the turned villagers after the Executors in droves. Those were easily dispatched, except it allowed the Vampire to capture the girls' mentor. Trapped in the town's church, the two girls fought for a week, slowly weakening in the face of the endless horde. The final straw was the vampire sending the mentor after the girls, which broke Gertrude and allowed the vampire to possess the girl. The two possessed Exorcists now turned against Catherine and nearly killed her.
In response, Catherine went into a trance like state, and when she awoke, she stood in a pile of corpses, topped with the bodies of her comrades. The Dead Apostle had fled the village already, as the Church's reinforcements arrived to find the girl who had purged the village. Subsequent examinations decided that Catherine was neither mentally, spiritually, or psychically capable working as an Exorcist. Her lower legs were beyond saving, and were replaced with prosthesis. Mentally, she was diagnosed with extreme PTSD, and suffered nightmares of her actions. Spiritually, she was deemed to weak of fate to face the foes that a an Exorcist would normally fight. Taking the news in stride, she left the Vatican, becoming a nun in a convent in the town of Redrock.
