Tamriel Empire

The Third Empire, also known as the Septim Empire, Cyrodilic Empire, Dragon Empire, the Empire of Tamriel or Tamrielic Empire is an empire founded by the conqueror Tiber Septim in the late Second Era. The Septim Dynasty ruled the Third Empire during the Third Era, but the bloodline was extinguished in the Oblivion Crisis; the Mede Dynasty rose to power in the early Fourth Era and has held the Imperial throne ever since.
