James Roxby was born Giacomo Rossiarino in the stone-shadowed village of Castelvecchio di Rocca Barbena, Italy, before moving to Australia and taking the name James Roxby. Roxby is a highly trained operative whose career began with quiet efficiency, progressing from general Infantry at Lavarack Barracks to the elite Special Air Service Regiment (SASR).

Following his rigorous six-week Cadre Course and nine-month Reinforcement Cycle training in Perth, Roxby served on denied operations in locations including Timor, Afghanistan, and the Solomon Islands. He was trained to be a ghost: methodical, detached, and able to vanish into a crowd, plan a hit, or walk away clean. His military career ended due to a serious injury sustained in Kandahar Province.

After his discharge, Roxby briefly served in the Victorian Police, fast-tracked due to his SAS credentials, but became disillusioned with the court system and legal loopholes. For over five years, he has been a Senior Operative for the Australian Federal Police's secret "black ops" division, FOCUS (Federal Operatives for Covert Urban Suppression). Operating outside the traditional legal framework, Roxby is tasked with executing justice against high-value targets by arresting, trying, and passing the death sentence on the spot. He is known for being measured, strategic, and controlled, always looking for a way out.
