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. Sanghelios is inhabited by approximately 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. It's atmosphere consists of oxygen, carbon dioxide, and nitrogen but also 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 was likely the area of large conflict between Separatist and Loyalist forces.

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

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