Atrion
From Tardis Wiki, the free Doctor Who reference
The Atrions were a species identical in appearance to Humans, native to the planet Atrios. The Atrions traded peacefully with their neighbours on the twin planet of Zeos, until both sides fought each other in a five-year long nuclear war. Those who attempted to parlay with the Zeons were branded traitors as the war ground on.
Atrion society was lead by the Marshall, a belligerent, glory-seeking individual, and the peace-loving Princess Astra of the royal house of Atrios. The royal house was notable in that the secret of the sixth Key to Time was passed down from generation to generation. (DW: The Armageddon Factor)
