Jon Murdoc was an N7 commando of the Systems Alliance military. As an Earth-born, Jon had a rough childhood in the slums of Earth, and inevitably developed a gritty edge to his personality. Jon enlisted into the Systems Alliance Navy at the age of eighteen, in order to avoid falling into the trap of gang culture and poverty. Early in his military career Jon found himself facing an overwhelming enemy force, a massive swarm of rabid Vorcha. Jon risked his own life to save his fellow soldiers and defeat the enemy despite the impossible odds. His bravery and heroism have earned Jon medals and recognition from the Alliance fleet. Jon's tour of duty brought him across many places and eventually to the Citadel to receive a medal from the Alliance Councilor, himself.
