Around 100,043 BCE, the planet was the test site for one of the twelve original Halo rings. The Halo was set to a low power setting, but still managed to kill every organism with a nervous system on the planet. The planet then went into a state of gradual ecological collapse.
The Pheru was an animal species indigenous to the planet, and was popular among humans and San'Shyuum as pets. Its forests which covered the planet were home to a type of semi-sentient tree.
