Traken Union

The Traken Union (or Empire of Traken) was a group of five or six allied planets centred around the star system of Mettula Orionsis. (PROSE: Divided Loyalties) At the heart of that system was Traken, the capitol planet of the Empire. Its leader was the Keeper of Traken, who brought peace to the Union through the power of the Source.

Peace was a major characteristic of the Empire. It was known for its universal harmony. Some said that there was so much goodness that evil died away when it arrived on Traken. The Fourth Doctor once described the Traken Union as "a whole empire held together by people just being terribly nice to each other." (TV: The Keeper of Traken)

In 1981, entropy built up in the universe and destroyed the Traken Union. (TV: Logopolis) The only remaining Trakenites were Nyssa and the inhabitants of Serenity, the outpost of Trakenites most remote to Traken. (PROSE: Cold Fusion, AUDIO: The Guardians of Prophecy)
