Sanghelios

Sanghelios is the Elite homeworld. It is the fourth planet from their collection of stars, Urs, Fied, and Joori. It has two moons, Qikost and Suban. It is rich in Forerunner artifacts in which the Sangheili worship.

Background
It is known that it is a mostly dry and arid planet with a gravity of 1.375 G's. It's atmosphere consists of oxygen, carbon dioxide and nitrogen. The surface temperature is at average -5C to 96C. The population of this planet reaches an amazing 8.132 billion inhabitants.

There is a war college in the Iruiru region of Yermo, Sanghelios. It is home to a large civilian population of Sangheili, and possibly some form of defense force (most likely a large fleet). Sanghelios is also likely to be the location of an ongoing battle due to Covenant Civil War. Because of the Elites' secession from the Covenant, it is probable that Sanghelios became the capital of the Covenant Separatists.

The planet itself is illustrated in the Beastarium and is shown very similar to Earth, but with a somewhat more scattered landmass in contrast with bodies of water. It's atmosphere also has a reddish hue to it, perhaps indicating a high iron content, like Mars.

At the end of the Human-Covenant War, the Arbiter, Rtas 'Vadum, and the carrier Shadow of Intent depart for Sanghelios.
