Kasterborous

Kasterborous (Cas-TER-bor-os) was the constellation in which the planet Gallifrey was located. (TV: Pyramids of Mars) The Sixth Doctor mentioned that Kasterborous was made up of seventeen suns. (AUDIO: Trial of the Valeyard) When explaining where he was from, the Doctor sometimes mentioned that Gallifrey was located in Kasterborous, (TV: Attack of the Cybermen, Voyage of the Damned, The Day of the Doctor, AUDIO: An Earthly Child) and so did Jack Harkness and Clara Oswald while respectively pretending to be the Doctor. (AUDIO: Piece of Mind, TV: Death in Heaven)

The Sixth Doctor said it was "just to the left of Karn." (AUDIO: Vortex Ice) The constellation was named by the Minyans. As no Time Lord was allowed to know Gallifrey's personal future, TARDISes were prevented from entering Kasterborous after a certain date. (PROSE: Goth Opera)

Kasterbourous was also the name of the astrologist who gave the largest contribution to the "New Astrology", occurring between the third millennium and the beginning of the fourth millennium. The Time Lords appointed one of their constellations with that name. (PROSE: Short Trips: Zodiac)

The Doctor's parents owned a summer house in the Kasterborous of another universe. (PROSE: The Infinity Doctors)

The Racnoss Wars were waged by the Time Lords in response to a precognition forseeing Racnoss Webstars swarming throughout Kasterborous. (AUDIO: Empire of the Racnoss)

During the War in Heaven, Kasterborous was torn apart and erased from history when the Eighth Doctor used the Edifice to destroy Romana III's Gallifrey. In the post-War universe, Marnal was unable to find Kasterborous anywhere in space or time. (PROSE: The Gallifrey Chronicles)
