Krystyna Walker

Unable to carry on living in London as he was at the time, Mark took the live-in Tech position at the Deveraux College when his wife, Krystyna, was murdered. He brought with him Alix, the couple's thirteen-year-old daughter, who later joined the Newbolt Wing. Mark is one of those people who's not happy unless he's helping someone, a fact that makes his job at Deveraux a prefect match for his personality.

A British-Polish Deveraux agent, Alix's talent lies in her ability to unite people - be they her friends, colleagues, or family. She could only be described as a social character, although she has slowly learnt to deal with being alone for large periods on missions. Following her mother's death, in the last few years Alix has begun to strongly embrace her Polish side in an effort to bring her closer to her mother's roots.

Katarzyna, Alix's maternal grandmother, is a retired nurse from Józefosław in Poland. Although Alix and Artur are the closer of her mother's parents, she is still deeply fond of her babcia. Katarzyna enjoys spending time with her only granddaughter, spoiling her even into her twenties, and is keen for Mark and Alix to visit her again soon.

A baker by trade, Artur is Alix's dziadek - her maternal grandfather. Although he was due to retire three years ago, Artur has refused to close or sell his bakery, insisting that as long as people purchase his goods Zawadzkie PiekarniaZawadzki's Bakery shall open every day without fail. Both proud and fond of his granddaughter, Artur keeps has suggested many a time that she ought to stop flirting with journalism and return to Poland to join him in partnership. Although the subject was rarely broached between them, until she moved to London, Arthur wished Krystyna, his only daughter, to inherit the business.
