Kalaya
From Tardis Wiki, the free Doctor Who reference
Kalaya was the planet inhabited by the Kalarians, as well as the 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 22.5 Earth hours and it had at least 3 moons.
It was the first planet to be captured by the Selachian Empire and the last to be taken back. (PDA: The Final Sanction)
