Faun Hakkor
From Halopedia, the Halo wiki
Faun Hakkor is a planet in an unknown system, which was once settled by ancient space-faring humans. It shares its system with Charum Hakkor, Ben Nauk and twelve other planets.
The Pheru were an animal species indigenous to the planet, and were popular amongst humans and San'Shyuum as pets.
Around 100,300 B.C.E, 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.
