During the Cold War, Ralan served as a Private within the ranks of the Sith Empire. Stationed on Taris, he found himself inside the laboratory of Doctor Nasan Godera alongside Eckard Lokin when rakghouls launched an assault. Despite the chaos, Ralan outlived his comrades in the battle, successfully eliminating the last of the rakghouls before ultimately dying from his injuries. Crucially, he did not become a rakghoul, suggesting that his fatal wounds were inflicted by weapons rather than rakghoul bites.
