Born in the bustling Caerus system in 3277, his early years were marred by tragedy and a desperate will to survive in a galaxy where danger lurked around every asteroid. The death of his mother in a brutal terrorist attack left a young Harrison under the sole guardianship of his father, a notorious pirate lord and leader of the 'The Black Hand.' Under his father's tutelage, he learned valuable skills such as spacecraft piloting and weapon handling and quickly made a name for himself within his father's clan, gaining the nickname 'K1ller4Hire' for his brutality and readiness to tackle any challenge thrown his way. Despite his family ties and promising skills, Harrison became disillusioned with the pirate lifestyle, and at the age of 18, seeking redemption and a fresh start, Harrison left behind his father's legacy to join the Federal Navy under a new identity: Regis Noct.

It was in the Navy where Harrison's innate talents truly flourished. Despite his success, however, he found it difficult to conform to the rigid confines of military structure and eventually left the Navy. Looking for a change of scenery, Harrison went on multiple exploratory voyages into uncharted space before returning to the bubble and embracing a new life as a mercenary and weapons dealer. Although he left many aspects of his previous life behind, the skills and lessons learned during his naval officer days, as well as his pirate upbringing, continue to influence his decisions to this day.
