Yonhe

Yonhe is a small moon located somewhere in Covenant-controlled space within the Orion Arm of the Galaxy. The satellite is the homeworld of the alien race known as the Yonhet.

Background
Yonhe's atmosphere is similar to that of Earth, being composed of oxygen and nitrogen. Yonhe was discovered by the Covenant at a point in time prior to the Human-Covenant War. When the Covenant made contact with the Yonhet, they viewed the small native population as militarily insignificant to consider them full signatories to the Covenant empire.
