Throne Ship of the Skithra

 was a spaceship, owned by the Queen of the Skithra.

The ship was originally build by Venusians. It was stolen by the Skithra, as they believed that they didn't need to build anything by themselves, since they could take existing technologies from others. The Skithra used inventions of other species, such as a Klendov warp drive and a Dullirian resonator to repair the ship.

In 1903, they kidnaped Nikola Tesla, so that he could repair the ship. When Tesla refused to do so, they threatened to kill Yasmin Khan, who was accidentally teleported to the ship alongside with Tesla. The Thirteenth Doctor managed to teleport herself to the ship and confronted the Queen. She took Yaz, Tesla and herself back to Earth. The Doctor planned to destroy the ship, using Tesla's tower in Wardenclyffe, but the Queen left the ship during the attack. Nevertheless, the Doctor teleported her back to the ship. Nikola Tesla turned his generator on and forced the Skithra to escape Earth. (TV: Nikola Tesla's Night of Terror)
