Kate Scott, also known as Sister Kate and codenamed Iron Maiden, is a female Terran nun and one of the founding members of the AX—a special division of elite priests and nuns in the Vatican Ministry of Holy Affairs. With her body in a coma, Scott's consciousness is projected through holographic technology. She served as the captain of the AX air battleship Iron Maiden and its successor, the Iron Maiden II.
Sister Kate has long blond hair and a mole on her cheek.
Her arcana in Thores' tarot cards is The Temperance.
The Iblis/ Angel of the Burning Sands ArcEdit
Kate informs Caterina that Abel and Tres have arrived back in Rome.
She helps assist Abel, Esther, Ion and Petros when Radu attacks them with the Goliath tank by destroying it. The Iron Maiden picks the trio up and they continue their journey back to the Empire in an airship. Kate reports to Abel that Ion is just a bit anemic, and is about to talk about Esther when she notices Abel appear seemingly distracted. After witnessing the state of his torn cassock, a shocked Kate sends Abel away to get dressed. Kate explains to Tres that Esther is sleeping on tranquilizers and kept saying that that wasn't Father Nightroad, it was a monster.
The AX Agents, Petros and Ion discuss what to do after being warned by Radu that the Iblis will destroy Carthage and everyone in it, including Lady Caterina.
Later on, she initially opposes Esther's plea to go down to Carthage to help Abel, but is persuaded by Tres to let her do so when he points out it will be just as dangerous for her to be on the battleship as they head towards the embassy to fight Radu.
The Throne of Roses ArcEdit
Kate congratulates Esther on her good first impression of the Albion media and informs her the Pope will arrive tomorrow. Esther asks her the whereabouts of Abel, and Kate recalls that he should be in Londinium on a mission to apprehend a priest by the name of Obridge, who had tried to sell documents from the Royal Palace to pay off his gambling debts. Kate becomes distressed as she witnesses Esther being kidnapped and subsequently falling from a helicopter.
The Crown of Thorns ArcEdit
Sister Kate sends a message through the radio to William who is with Vanessa Walsh. She confirms William's prediction was right - a large amount of weapons have suddenly vanished from the Albion black market in the recent months. Enough to start a war, but it appears they were not taken by gangs; no one knows where they went. The Professor thanks Kate and informs her that the person who attacked him and Esther earlier was an artificially strengthened soldier by the name of Sergent Jack Ironside. Jack Ironside supposedly died two years ago in the Percy Rebellion along with the rest of the 44th Regiment. His funeral was arranged by his supervisor, Mary Spencer, but the church has no burial records of him or any other of the more than one hundred members of the 44th Regiment.
Kate seems stumped by this information, while William mentions he has more interesting news to share. He cuts the conversation short, however, knowing someone is eavesdropping on them. William informs her that he can tell her that chaos will ensue in this country soon, that he is going to someone to collect some information, and for her to stand watch in the sky and act accordingly when that time comes. Kate agrees and pleads for him to be cautious after what happened to Abel, but the radio suddenly cuts of due to outside interference.
