Christmas (town)

Christmas was a level-2 human colony located on the planet Trenzalore, described by Tasha Lem as little more than a farming community. It contained a residual crack in space-time left behind after the Eleventh Doctor rebooted the universe.

History
The town became the focus of universal attention due to a signal emanating from the crack in the Clock Tower. This signal also contained a truth field that encompassed Christmas, was of Time Lord origin, and asked The Question "Doctor Who?". The answer of the Doctor's real name would be proof to the Time Lords that they had found the right place to return to the universe. This led to the Siege of Trenzalore, and for the next three hundred years the Doctor, alongside the village's inhabitants and the Papal Mainframe's soldiers, defended the town from Sontarans, Daleks, Weeping Angels and Cybermen. Eventually all but the Daleks retreated or were destroyed.

Eventually The Doctor's TARDIS returned, allowing Clara to answer the question, stating that "the Doctor" is the only name that mattered. Although they did not return, the Time Lords did grant the Doctor further regenerations when his last incarnation was dying before closing the crack. Using his regeneration energy, the Doctor obliterated the Daleks besieging the town, at the same time causing a shockwave that damaged the town but left it intact. With the threat gone, the Doctor and Clara returned to his TARDIS and left the town. (TV: The Time of the Doctor)

Appearance
Daylight lasted only a few minutes in Christmas, during which the The Doctor would often stand on the Clock Tower's balcony and look out over the town, reminding himself of what he was protecting. The town was lit by 20th century-styled street lamps during the long nights.

The weather was constantly snowing (possibly the reason the town was named "Christmas", and the town was decorated with Christmas lights and Christmas trees.

Individuals

 * Abramal was a man coupled with a woman called Marta. They told the Doctor and Clara about the truth field.
 * Barnable was one of Doctor's best friends during his life in Christmas. He waited for the Doctor outside the TARDIS.

Behind the scenes

 * The Christmas town's filming location was an old army training place. The buildings there didn't have windows, so the houses' windows had to be faked.
