Large desert regions stretch across the interior portions of the planet's continents, forcing the significant portion of Sanghelios' population to live on the coasts and islands. These locations are usually encircled by steep mountain ranges or rocky tombolo drifts, which provide much needed protection during the planet's harrowing rain season.{{Ref/Reuse|universe}} Many [[Forerunner]] artifacts and structures exist on the planet, which are the topic of worship, as well as the cause of historical [[war]]s between the Sangheili and the [[San'Shyuum]] before the formation of the [[Covenant]].{{Ref/Reuse|bestiarum}} The large size of Sanghelios' two [[natural satellite]]s—[[Qikost]] and [[Suban]]—has great effects on the planet's tides.{{Ref/Novel|[[Halo: The Cole Protocol]]|Page=90}} Much like Earth's Satellite [[Luna]], Frigid winds from the south pole of Sanghelios were spread across the southern regions of the planet.{{Ref/Novel|BC|Page=35}}

Sanghelios is home to numerous animal and plant species, widely different from those on [[Earth]]. Some of these animals are domesticated, like the [[colo]] which is farmed across Sanghelios for its meat.{{Ref/Novel|Halo: The Thursday War|Page=205}} [[Doarmir]] are furry animals that are hunted for their fur, which is used for clothing.{{Ref/Novel|TCP|Page=159}} [[Helioskrill]]s are large, predatory creatures that live in the mountains of Sanghelios, respected by the [[Sangheili]] for their hunting positions.{{Ref/Novel|TCP|Page=188}} Intestinal parasites—[[nishum]]—are common pests on the planet.{{Ref/Novel|Halo: The Thursday War|Page=79}} The waters on Sanghelios are home to large, predatory [[Unidentified aquatic creature|aquatic cephalopods]] that prey on unsuspecting creatures that wander into their territory,{{Ref/Anthology|Evo|[[The Return]]}} alongside [[Electric kesh]], [[Snap-tail]]s.<ref name="SOI">''[[Halo: Shadow of Intent]]''</ref> The skies of Sanghelios are often filled with a variety of avian-like animals.{{Ref/Novel|Halo: The Thursday War|Page=261}} Sangheili farmers would train predatory animals, known as the [[quillick]], to hunt mammals for them.{{Ref/Novel|BC|Page=25}} [['sKelln]] are leather-winged predatory animals capable of flight.{{Ref/Novel|BC|Page=36}} [[Thremaleon]] were a vicious, nearly extinct, species of lizard that the Sangheili would use for leather.{{Ref/Novel|BC|Page=90}} The hooved [[keifra]] are also native to Sanghelios,<ref>'''[[Halo: Hunters in the Dark]]''', ''page 102'' (Google Play edition)</ref> as are the [[velithra]] which are domesticated by the Sangheili to serve as beasts of burden.<ref name="hitd137">'''Halo: Hunters in the Dark''', ''page 137'' (Google Play edition)</ref> There are also small, rat-like creatures that live on the planet, hunted by adolescent Sangheili.{{Ref/Novel|[[Halo: The Flood]]|Page=5}}

The planet is also home to numerous types and varieties of vegetation. [[Irukan]] is a species of grain commonly grown on the planet, usually by [[Kig-Yar]].{{Ref/Novel|Halo: The Thursday War|Page=62}} [[Kafel]] is a plant with a durable, wooden trunk that is often used in Sangheili construction.{{Ref/Novel|TCP|Page=89}} The [[G'lul'g tree]] is a carnivorous tree-like organism native to the planet.{{Ref/Novel|Obl|Chapter=14}}

The [[Sangheili]] evolved in the tropical wetlands of Sanghelios.<ref>'''Halo: Broken Circle''', ''page 38'' (Google Play edition)</ref> Sanghelios had at one point been visited by or had been in contact with the [[Forerunner]]s, as Forerunner artifacts were left throughout Sanghelios' surface. During their contact, the Forerunners had placed a [[Guardian]] on Sanghelios, in order to enforce their [[Mantle of Responsibility]] and police the Urs system. The Guardian rested for many millennia in the depths of the [[Csurdon Sea]], over which the [[city]] of Sunaion would later be built in homage to the great machine.{{Ref/Site|Id=Halo Waypoint: Sunaion|URL=https://www.halowaypoint.com/en-us/universe/locations/sunaion|Site=Halo Waypoint|Section=Universe, Locations|Page=Sunaion|D=13|M=4|Y=2016|LocalArchive=https://archives.halopedia.org/waypoint/www.halowaypoint.com/en-us/universe/locations/sunaion.html}}

After being returned to their homeworld, the Sangheili discovered artifacts left by the Forerunners on their planet. The Sangheili revered the objects these "gods" had left, and considered tampering with them a heresy beyond any other.<ref name="enc120">'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 120'' (2011)</ref> The tyrannical [[Arbiter]] [[Irsu 'Labat]] took control of the entire [[Qivro]] continent, but he was overthrown by a coalition of [[kaidon]]s known as the [[Swords of Sanghelios]].{{Ref/Reuse|swords of sanghelios}}  

Sanghelios became the initial capital of the Covenant Empire.{{Ref/Book|Id=enc22pg229|Enc|Page=228-229}}{{Ref/Reuse|universe}} During this time as the capital, the Covenant would dive into the myriad of Forerunner ruins on the planet.{{Ref/Reuse|enc22pg229}} Once the mobile city of [[High Charity]] had completed its construction in [[648 BCE]], Sanghelios returned to Sangheili exclusivity.{{Ref/Reuse|universe}} As part of the Writ of Union, the planet would receive massive imports of manufactured goods and food in exchange for for military service.{{Ref/Reuse|enc22pg229}} The planet continued to provide soldiers for the [[Covenant military]] for centuries.{{Ref/Reuse|universe}}

Since [[2553|March 2553]], a majority of Sanghelios has become engulfed in a [[Blooding Years|civil war]] between the [[Swords of Sanghelios]] loyal to Arbiter Thel Vadam and the factions—such as the [[Servants of the Abiding Truth]]—that sought to worship the Forerunners as gods and exterminate humanity.<ref>'''[[Halo: The Thursday War]]'''</ref> By [[2558]], the Arbiter's followers were firmly in control of the planet, though Sanghelios and most Sangheili colonies remain in a tense state.{{Ref/Reuse|universe}} In that year, [[Jul 'Mdama's Covenant]] attacked the world igniting a [[Sanghelios global war|global war]].{{Ref/Novel|LOO|Chapter=21}} The [[Battle of Sunaion]] marked a fatal blow to Jul 'Mdama's Covenant.{{Ref/Reuse|Halo Waypoint: Sunaion}} During the battle, a Forerunner [[Guardian]] that had lain beneath the [[Csurdon Sea]] for millennia emerged and departed for [[Genesis]].{{Ref/Level|Halo 5: Guardians|[[Battle of Sunaion (level)|Battle of Sunaion]]}}

On [[2558#October|October 28, 2558]] the Swords of Sanghelios emerged victorious over Jul 'Mdama's Covenant at the [[Battle of Sunaion]].{{Ref/Level|H5G|[[Guardians]]}} However, when [[Fireteam Osiris]] and [[Blue Team]] returned through a [[slipspace portal]] in [[India 127|a Pelican]] from Genesis, they found the planet blacked out and realized that Cortana [[The Reclamation|sent]] a Guardian to Sanghelios too after the Sangheili were too proud to accept her offer. The Spartans were able to track the Arbiter and his surviving people to [[Nuusra]] where they reunited with the Swords of Sangheilos, Commander [[Sarah Palmer]] and Dr. [[Catherine Halsey]]. The Arbiter invited them to join them for a meal while Halsey revealed that she had managed to use the Forerunner technology in the area to make contact with the {{UNSCShip|Infinity}} which would appear off the far side of Suban for fifteen minutes the next day at eighteen hundred hours standard time. Palmer explained that soon after Cortana sent out her manifesto, a Guardian arrived on Sanghelios and began taking most of what remained of 'Mdama's Covenant fleet with its standard armament before using an EMP to shut down power across the hemisphere. Rumor had it that the Guardian was on the other side of the planet blacking out that side too since its effect had a limited range. The next day, the humans departed Sanghelios in the Pelican recovered from Genesis and managed to avoid any trouble while rendezvousing with ''Infinity''. However, the Arbiter received reports of Forerunner soldiers actively pacifying cities that resisted the Guardian.{{Ref/Novel|BadB|Chapter=1}}

 

 

After Cortana's death on [[Installation 07]], the Created relinquished their grip on Sanghelios and the rest of Urs system. While many keeps and kaidons on Sanghelios remained steadfast in their support on the Swords of Sanghelios, others sought other factions to pledge their allegiances, with the Banished being well received by some keeps; some of these keeps even allowed the Banished to enter the Urs systems without problems, starting a [[Battle of Suban|conflict]] between the Swords and the Banished on Sanghelios' moon, Suban.{{Ref/Reuse|BftBM}}

Sanghelios is considered to be the cradle world and the center of government of the [[Sangheili]].{{Ref/Reuse|universe}} As with the nature of Sangheili governments in general, the planet has no global capital and most of Sanghelios' inhabitants live in city-states led by and named after a particular Sangheili family.{{Ref/Novel|TCP|Page=93}}{{Ref/Novel|Halo: Glasslands|Page=58}} A given state is governed by a single [[clan]] residence and assembly house known as a [[keep]], headed by a [[kaidon]] selected by a council of [[elder]]s. There are usually a number of "client keeps" belonging to different clans under the leading keep's rule,<ref name="glass2">'''Halo: Glasslands''', ''page 94''</ref> though a state's elders will assume the kaidon's clan name as a title signifying their position, regardless of the name of their own family keep.{{Ref/Reuse|gl57}} The states on Sanghelios vary greatly in size and wealth, ranging from small, rural ones like [[Mdama]] to urban city-states like [[Ontom]], which mix ancient Sangheili architecture and modern structures and aesthetics.<ref name="urbanOntom">'''Halo: Glasslands''', ''pages 135-136''</ref> As a developed Sangheili world, Sanghelios is host to hundreds of different keeps competing for power and influence by utilizing both politics and martial force.{{Ref/Reuse|sangheili waypoint}}

Sanghelios is the location of the single greatest population of Sangheili.{{Ref/Reuse|universe}} Most of Sanghelios' population remains on the planet for their entire life. However, those who showed either intellectual or physical skill were often recruited by the Covenant.{{Ref/Reuse|HE311}} By [[2552]], Sanghelios was inhabited by approximately 8.132 billion individuals.{{Ref/Reuse|bestiarum}} However, the population sharply dwindled to less than four billion after the [[Blooding Years]], a civil war that engulfed most of the planet; many of the planet's inhabitants fled to the population centers on Sanghelios' [[natural satellite]]s of [[Qikost]] and [[Suban]].{{Ref/Reuse|universe}} After the dissolution of the Covenant, [[Unggoy]] continue to live on the planet as workers for the Sangheili, and [[Kig-Yar]] merchants often visit to trade with the planet's inhabitants. [[Human]] officials occasionally visited for diplomacy,{{Ref/Novel|Halo: Glassland}} or stayed to work.{{Ref/Reuse|catalog}} A few Jiralhanae were permitted to work as laborers for Sangheili masters.{{Ref/Novel|Halo: Glasslands|Page=134}}
