Ember (planet)

Ember was a planet in the far future. It was the home of the last humans in the universe. Using a psi-gate, they sent their minds back to 21st century Earth and took over the Somnus Foundation. They wanted to survive the end of the universe by turning the human race into a group mind. They were defeated by the Fifth Doctor and Turlough. Afterwards, the Doctor visited Ember to say goodbye to the dying Xen, the last surviving human in the universe. (AUDIO: Singularity)
