Erlem Marh was a male Human who held the position of an officer within the Imperial forces during the time of the Galactic Civil War.
During the year 1 ABY, Lieutenant Erlem Marh found himself stationed on the planet Dathomir when an accident occurred at the Imperial Research and Prison Facility. The Blackwing virus being researched there broke free from its containment, resulting in widespread devastation and transforming many inhabitants into ravenous undead beings. Subsequently, the Galactic Empire swiftly established a Quarantine Zone in an attempt to control the spread of the infection. A small number of individuals, including Lieutenant Marh, managed to survive the initial outbreak but were consequently trapped within the Quarantine Zone. These survivors then created fortified camps to defend themselves against the relentless zombie attacks, seeking safety and hoping for eventual rescue. Erlem Marh, whose first name was Stephon, sought refuge in Camp Delta, alongside a stormtrooper known as TR-522 and a Bothan named Oona Wran. As Lieutenant, Erlem Marh took responsibility for the camp's front lines, often enlisting the help of spacers who dared to enter the Quarantine Zone.
Erlem Marh appeared as a non-player character in Star Wars Galaxies, a massively multiplayer online roleplaying game released in 2003. The game was developed by Sony Online Entertainment and published by LucasArts. The game was shut down on December 15, 2011. Erlem Marh was integrated into the game through "Game Update 14," also known as the "Death Troopers" update, which went live on October 12, 2009.
