Fedders was a young marine in Raynor's Raiders. Roughly two months after the Fall of Tarsonis, he found himself on Char as part of a Raiders team led by Jim Raynor, descending into a series of tunnels below the planet. Fedders survived the numerous waves of zerg thrown at the force, though was shaken by the experience.
Fedders was one of the Raiders who made it to the lowest Zerg cavern, basically acting as a breeding chamber. The zerg hardly took kindly to the intrusion and launched a large wave of zerg at the force. Fedders, like many others, was killed within moments.
