Ember (planet)

Ember was a planet colonised by humans before the 44th century.

Astronomical data
Ember was characterised by the cloud belt which covered the planet. These clouds were made of ice crystals with tiny electrical charges. The sky fish evolved to fly through these clouds, but they could only live outside them for a longer while.(TV: A Christmas Carol)

Culture
The human colonists of Ember had a society reminiscent of Victorian era Britain. They used Gideons as a currency and had a president, though real power was held by the Sardick family. They originally called Christmas "The Crystal Feast", but it was later just called Christmas. There was no lottery. (TV: A Christmas Carol)

History
The Eleventh Doctor visited the planet when a ship containing his companions, Amy Pond and Rory Williams, began to plummet through its atmosphere. The Doctor visited Sardicktown and convinced Kazran Sardick to allow the ship to land. (TV: A Christmas Carol)

Behind the scenes
