D'Ath was stationed in Trilliack during the outbreak of the Pandoran War, and helped to defend the system against threats from the Pandorans themselves, as well as from traitors within the allied force itself. He assisted in taking down CSN Drachma, as well as leading the operation to capture Isabel Nelson, and Preston Young.
