Sardicktown

Sardicktown was a city on a human colony planet near the Horsehead Nebula. It was run by the Sardick family in the 44th century. At night, fog was prevalent throughout the town. This fog had properties that allowed certain species of fish to swim through it. Since this included a shark-like species, Elliot Sardick created a machine that could control the clouds and fog to keep the fish away when people were on the streets. The Sardicks used permanent fog banks to keep people cryogenically frozen.

There was a day when the cloud bank fell and fish attacked a school. Nobody was seriously harmed. The Eleventh Doctor built several snowmen throughout Sardicktown. (DW: A Christmas Carol)

behind the scenes

 * The architecture of this town seems to bear a strong resemblance to Victorian Britian. Why this occurs from the perspective of the 'Doctor Who Universe' is unknown. However from a real world point of view, such an occurrence is because the storyline of DW: A Christmas Carol, is based on the Charles Dickens novella A Christmas Carol.
 * In the browser-based game Doctor Who: Worlds In Time, Sardicktown is located on a planet called Ember. Ember is the planet the player visits after Earth.
