Sun-singers of Akhet

The Sung Sings of Akhet was a name given to the seven planets orbiting the star Akhaten. All the inhabitants of the seven planets believed that life in the universe originated in a pyramid, residing in the rings of their sun. The Eleventh Doctor believed that their creation myth was "a nice story."

The fate of the planets and its people after the destruction of Akhaten is unknown. (TV: The Rings of Akhaten)
