In 3640 BBY, during the Galactic War between the Galactic Republic and the reconstituted Sith Empire, Eron served as a soldier in the Republic Army. The soldier was assigned to Sergeant Shanra Immel's squad and worked with SpecForce Colonel Jace Malcom in a battle on Kalandis Seven, a desolate Inner Rim planet covered in fog. During the battle, Eron and the squad were tasked with the destruction of the local Sith-controlled spaceport. On the trek to the spaceport, the squad was attacked, and fellow squad member Corporal Amden vor Keioidian was fatally wounded. Immel activated Keioidian's med tracer before making the decision to leave him behind, ordering the squad to move out.
Three hours later, Eron, Immel, Malcom, and the rest of the squad reached their objective and went on to plant several targeting beacons, which would allow Republic starfighters to destroy the spaceport regardless of the fog. Eron and the squad succeeded in planting the beacons, and the spaceport was destroyed shortly after.
Eron liked to collect antique music recordings.
Eron appeared, albeit voice only, in Alexander Freed's short story "The Last Battle of Colonel Jace Malcom," which was published in the 137th issue of the Star Wars Insider magazine on October 23, 2012.
