The 127th Emperor Hetto was a starship in the Conquest Fleet sent by the Race to Tosev 3. It was bannership for Fleetlord Atvar, and was commanded by Kirel. Atvar made his residence there and commanded Race forces in the fighting, before moving down to Cairo.
Race scientists, Ttomalss among them, stayed on this ship and used it for their studies and experiments involving Tosevite sexuality on captive subjects. Several diplomats from the Big Five boarded the ship in the early stages of the war to negotiate with Atvar.
During the Race-German War of 1965, a Reich spaceship piloted by Johannes Drucker, vainly attempted to destroy the 127th Emperor Hetto with nuclear missiles. His missiles were intercepted and he was taken prisoner.
