New Alexandria

New Alexandria was a lifeless planet on the edge of the Capricorn Tract and orbiting a neutron star.

It hosted a domed complex containing the Crystal Bucephalus and the hotel that surrounded it, the Emerald Syphax. It was surrounded by the Time Vortex. (PROSE: The Crystal Bucephalus)

During the War in Heaven, the Mother and Father of the Shadow Spire saw campfires of "ritual and bone" hiding in Homeworld ruins on Ardethe. (PROSE: The Story So Far...)

At another point, New Alexandria was covered in a planet-wide library which was visited by the Seventh Doctor and Bernice Summerfield. (PROSE: Continuity Errors)

Behind the scenes

 * It is strongly implied that New Alexandria is built on the ruins of Gallifrey, with Kamelion even beginning to say that the planets have the same coordinates before being interrupted. (PROSE: The Crystal Bucephalus)
