Conner was born and raised on Mindoir, a small border colony in the Attican Traverse. When yhe was sixteen slavers raided Mindoir, slaughtering his family and friends. He saved by a passing Alliance patrol, and enlisted with the military a few years later.
Throughout Conner's military career, he held fast to one basic rule: get the job done. He's been called cold, calculating, and brutal. His reputation for ruthless efficiency makes his fellow soldiers wary of him. But when failure is not an option, the military always goes to him first. Conner sent 3/4ths of his unit to its death and murdered surrendering batarians on Torfan.
