Keskan

The Keskans were a humanoid race.

Once a race of thinkers, the Keskans were attacked by the Taalyens, forcing them to flee their homeworld. They eventually settled on a new planet, naming it Keska. During the Last Great Time War, the War Doctor crashed on their planet and turned their sky transmitters into a planetary shield to protect them from the Taalyens' orbital bombardment. (AUDIO: The Innocent)

Years after the Doctor left Keska, the Taalyens invaded the planet together with the Daleks, and enslaved the Keskans. Keska later became one of the Thousand Worlds in the Null Zone that the Daleks were granted by the Time Lords, setting up a large scale mining operation. (AUDIO: The Thousand Worlds)

When the War Doctor returned to Keska, he found that it, and all the other worlds in the Null Zone, were to be turned into spaceships that would be launched at Gallifrey, destroying it. The Doctor managed to thwart the Daleks' scheme, freeing the Keskans. By the time that the War Doctor and War Ollistra arrived to retrieve the Doctor's TARDIS, the Keskans were a peaceful and thriving species. (AUDIO: The Heart of the Battle)
