Arthur Lynch was the commander of the Free Planets Alliance forces stationed in the El Facil starzone during the Battle of El Facil in 788 UC. After the battle, Lynch was captured by the Empire while attempting to flee, and sent to a POW camp. Several years later, he would be returned to the Alliance as part of a prisoner exchange program, with orders from Reinhard von Lohengramm to orchestrate the military coup that would escalate into the Alliance Civil War.
