There are many Directors, but there is also one Director. Once a Director assumes, they surrender their identity to the Bureau and become one of its faceless lords. They see through each other's eyes and read each other's thoughts, and walk and speak in perfect sync when in groups. It is said they even share the same emotions. There is one per History, though they have been known to meet in person during dire times. Additionally, they also age unnaturally slowly, only looking just under thirty years old at one hundred. They are forbidden from seeking Longhood, however, and are to remain mortal until they decide to retire.
