Keska

Keska was a planet visited by the War Doctor during the Last Great Time War. The Taalyens tried to invade the planet but they did not succeed because of the artificial force field the War Doctor made using the communication satellites. Years after the Doctor left Keska, Taalyens, together with the Daleks, invaded and enslaved the Keskans. They were drilling on the planet's core to destroy it. (AUDIO: The Innocent)
