Traken

Traken was the homeworld of the Trakenites, a race of pacifists, and the capitol of the Traken Union. Its many plants required much care, a duty that was carried out by the Fosters.

The planet was in the system Mettula Orionsis and was watched over by the Keeper of Traken. It was said that there was so much good in the air that evil would just shrivel up and die.

The Doctor's companion, Nyssa, was a native of Traken. (TV: The Keeper of Traken)

The Second Doctor visited Traken with Jamie McCrimmon and Victoria Waterfield. (PROSE: The Astronomer's Apprentice)

The Fifth Doctor took Nyssa to Traken in the primeval age to cure her of an illness. (AUDIO: Primeval)

In 1981, whilst travelling to Earth from Logopolis in the Fourth Doctor' TARDIS, Adric and Nyssa witnessed Traken and Mettula Orionsis being destroyed by a wave of entropy. (TV: Logopolis)

Nyssa told the Fifth Doctor that the forests on Vortis reminded her of those on Traken. (AUDIO: Return to the Web Planet)
