Kalaya

From Tardis Wiki, the free Doctor Who reference

Kalaya was the planet inhabited by the Kalarians, humans and Ockorans during the war. Kalaya's atmosphere was similar to Earth's, though the gravity was higher. It was a temperate planet with dark waters and grey beaches. Its days were twenty-two and a half Earth hours and it had at least three moons.

It was the first planet captured by the Selachian Empire, and the last to be retaken. (PROSE: The Final Sanction)
