Kalaya was the planet inhabited by the Kalarians, as well as the Humans and Ockorans during the war. Kalaya was similar to Earth in terms of atmosphere and gravity, though the gravity was higher, giving Humans a feeling of heaviness. It was a temperate planet with dark waters and grey beaches. Their 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)
