Sanghelios

Sanghelios is the homeworld of the Sangheili race. Sanghelios is the fourth planet in a Triple Star System of stars Urs, Fied, and Joori. The planet has two Moons called Qikost and Suban. Many Forerunner artifacts and structures exist on the planet, which are the topic of worship, as well as the cause of historical wars between the Sangheili and the San 'Shyuum before the formation of the Covenant proper.

Background
Most likely due to the fact that Sanghelios has three suns, the surface is dry, arid, and considerably hot (like a desert), although water exists on the planet. Sanghelios has a gravity of 1.375 G's, and an average surface temperature of -5C to 96C. It's atmosphere consists of oxygen, carbon dioxide, and nitrogen. Sanghelios is inhabited by approximatley 8.132 billion Sangheili. The planet, as is illustrated in the Bestiarum indicates that it is similar to Earth in shape and extension, though the land masses are more scattered in relation to bodies of water. Its atmosphere has a reddish hue to it, perhaps indicating large amounts of iron.

Notable places: One of the most prestigious war colleges in the Iruiru Region of Yermo. The planet is of course home to a large number of civilian Sangheili, as well as a large defense force (possibly a large fleet). Sanghelios may have been the site of large conflict between Separatist and Loyalist forces.

At the end of Halo 3, the Arbiter, Rtas 'Vadum, and the crew of the carrier Shadow of Intent depart for Sanghelios.

Etymology
The name "Sanghelios" comes from the Latin sang and the Greek helios which mean "Blood-Sun". It is implied that this may refer to the "hot blood" of the warrior race that lives there.
