Shortly after the Ur-Quan enslaved Earth under the red Slave Shield, they erected a space station around it to help maintain the Hierarchy squandron based on Luna. Ten years after the enslavement, as part of normal crew transfer, Commander Hayes was put in charge of the station. During the war, Hayes has served on board several Alliance ships, including a Shofixti Scout and an Earthling Cruiser. He is one of the survivors of the terrible battle at Draco, where Ilwrath and Earthlings clashed. Hayes is not only a military man; he is also an intellectual who knows a good bit of information about most alien races, about recent history and about the art of war.
