Imperial Admiral Darlan Referum was a high-ranking officer of the Imperial Navy of the Unity, one of the nine Imperial Admirals that was in service during the First and Second Great Wars. Though his birthdate, birthplace, and exact age were unknown to the intelligence offices of the United Earth Government at the time of his death, he was suspected to have been born between 2325 and 2340, in one of the Unity's innermost planets. As Nitomians age slower than humans, his "human" age at his death could be estimated to be about 50.
