David Odonis Mortin, better known as Dom, once served in the Corlan Interplanetary Marine Corp (CIMC) as a Sergeant. He was drafted at a young age and rose in the ranks quickly thanks to his exceptional combat skills, battle instincts, and conventional weapons expertise. After an unfortunate encounter with a ranked officer, Dom was discharged from duty and returned home only to find out that Earth has been destroyed. Furious at his predicament, Dom single-handedly hijacked the military cruiser he was being sent home in and flew to the farthest reaches of the galaxy, not knowing what to do or where to go next. That is, until he met an exiled warrior seeking to redeem himself.
