'The Keeper is dying... Nothing can be normal at such a time.'
Under the watchful control of generations of guardians known as Keepers, the harmonious power of the bioelectric Source has enabled the planet of Traken to exist in peace for numerous millenia. The current Keeper's millennium is about to end; but before his powers wane completely, he senses the approach of an all-pervading force of evil about to inhabit the world of Traken. He calls on the Doctor to help save the future generations from an impending disaster, but the new Keeper is already staking his claim to the Source. As Melkur becomes the new keeper of Traken, the Doctor realises that his new enemy is an even deadlier foe — one he has met before!
The Keeper of Traken saw the introduction of Sarah Sutton as the lovely Nyssa, who went on to accompany the fifth Doctor.
