Valdore was a high-ranking official in the Romulan Star Navy in the 22nd century. In 2154, Valdore oversaw an operation to destroy relations between the Andorians and Tellarites by using a holographic disguised drone ship to frame both sides for attacks against the other. However, the operation backfired and Humans, Vulcans, Andorians and Tellarites joined together to counter the threat. (ENT: "Babel One", "United")
