==History==

===Early history===

[[File:H2A Terminals - Sangheili on Sanghelios.jpg|thumb|250px|left|Ancient Sangheili marching on Sanghelios.]]

The [[Sangheili]] evolved on Sanghelios in tropical wetlands on the planet.<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 deeps of the [[Csurdon Sea]], over which the [[city]] of Sunaion would later be built in homage to the great machine.<ref name="Halo Waypoint: Sunaion">[https://www.halowaypoint.com/en-us/universe/locations/sunaion '''Halo Waypoint''': ''Sunaion'']</ref> Towards the end of the [[Forerunner-Flood war]], the [[Librarian]] visited the planet to retrieve specimens of the Sangheili for preservation as part of the [[Lifeworker]]s' [[Conservation Measure]]. After [[Great Purification|the firing]] of the [[Halo Array]], the Sangheili that were preserved aboard [[Installation 00]] were [[Reintroduction|reintroduced]] to their homeworld to begin rebuilding their culture.<ref>'''[[Halo Legends]]''', ''[[Origins]]''</ref>

 

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''', ''page 120'' (2011)</ref> A tyrannical [[Arbiter]] once took control of the entire [[Qivro]] continent, but he was overthrown by a coalition of [[kaidon]]s known as the [[Swords of Sanghelios]].<ref name="swords of sanghelios"/> The first Sangheili interplanetary probes were launched from towers of glass and steel on Sanghelios. Sometime after, around the time the Sangheili developed [[anti-gravity technology]], the planet experienced a climate shift, and the Sanghelios launch towers were abandoned.<ref name="surface features">[https://www.halowaypoint.com/en-us/news/canon-fodder-surface-features '''Halo Waypoint''': ''Canon Fodder - Surface Features'']</ref> Over time, the Sangheili on Sanghelios developed their technology and became a space-faring race, subsequently colonizing several worlds. At some point, the [[Clan Battles of Sanghelios]] occurred on the planet. One of the [[battle]]s was fought between two large [[clan]]s in the forest of [[Tarjak]].{{Ref/Novel|Halo: Broken Circle|Page=30}}

 

In [[938 BCE]], the Sangheili encountered the [[Reformists|Reformist]] [[San'Shyuum]]—a race who also worshipped the Forerunners as gods, but had utilized Forerunner technology for their own needs, believing the technology had been left behind by the gods as gifts for their children.{{Ref/Novel|Halo: Contact Harvest|Page=147}} This sparked a [[San'Shyuum-Sangheili War|war]] between the two races over how to treat the relics. At first, the Sangheili attempted to keep the San'Shyuum away from Sanghelios and the San'Shyuum were unable to discover the location of the Sangheili homeworld.{{Ref/Novel|Halo: Broken Circle|Page=58}} Part of the war was fought on Sanghelios, with the San'Shyuum's [[keyship]], the [[Forerunner Dreadnought]], devastating military forces planetside. In time, the Sangheili learned of the San'Shyuum's belief in the Great Journey, where the Forerunners used the Halo Array to ascend to a god-like state, and wished to repeat this process on themselves. Coupled with this belief and the fact that the cause of war was obsolete, the Sangheili agreed to unite with the San'Shyuum into an alliance to avoid mutual [[extinction]].  

 

In [[852 BCE]], the two races signed a treaty known as the [[Writ of Union]] to form the early Covenant.<ref>'''Halo Encyclopedia''', ''page 30''</ref> However, [[851 BCE|the following year]], a civil war began on Sanghelios that would be referred to as the [[Rending]]. Several Sangheili opposed the Writ of Union, most notably [[Ussa 'Xellus]]. Some Forerunner artifacts were even damaged during the rebellions. In response, Covenant attack fighters were sent to the state of [[Xellus]] and destroyed the state and keeps, killing hundreds of Sangheili. This led to the 'Xellus clan fleeing to the southern region of [[Nwari]] on Sanghelios to plot against the Covenant, though they were eventually forced to flee to [[the Refuge]].{{Ref/Novel|Halo: Broken Circle|Page=37}}

 

Sanghelios became the initial capital of the Covenant Empire. However, once the mobile city of [[High Charity]] had completed its construction in [[648 BCE]], Sanghelios returned to Sangheili exclusivity. The planet continued to provide soldiers for the [[Covenant military]] for centuries.<ref name="universe"/> Many Sangheili manufacturers on and around the planet provided weapons and vehicles for the Covenant. During the [[Human-Covenant War]], many Sangheili warriors from Sanghelios joined the Covenant's campaign against [[human]]ity until the [[Great Schism]].<ref name="HE311"/>

 

[[File:Battle Of Sunaion.png|thumb|250px|The Swords of Sanghelios engage Jul 'Mdama's Covenant at Sunaion.]]

After the Human-Covenant War, [[Arbiter]] [[Thel 'Vadam]] and [[Rtas 'Vadum]] returned to Sanghelios after aiding the [[United Nations Space Command]] in defeating the Covenant.{{Ref/Level|[[Halo 3]]|[[Halo (Halo 3 level)|Halo]]}} Most of the Sangheili who served in the Covenant returned to Sanghelios or its colonies when the Covenant was dissolved.{{Ref/Novel|Halo: Broken Circle|Page=265}} However, the dismantling and abandonment of most of the Covenant's religion and politics led to civil unrest and feuding throughout Sanghelios.<ref name="universe"/> The Arbiter was considered by many as the leader of Sangheili that truly abandoned their religion. 'Vadam planned to visit each state to make his case for permanent peace with the humans they had battled for so many years.{{Ref/Novel|Halo: Glasslands|Page=130}} These reforms were not met with universal approval. By [[2553#January|January 2553]], there was great dissent among disparate Sangheili factions, especially from the more devout believers in the Forerunners' divinity. Some, such as [[Avu Med 'Telcam]] and his [[Servants of the Abiding Truth]], saw the Arbiter as a [[Treason|traitorous]] leader that has betrayed their faith and sought to finish their war with humanity.<ref>'''Halo: Glasslands''', ''pages 58-61''</ref>

 

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 name="universe"/> In that year, [[Jul 'Mdama's Covenant]] established a presence on Sanghelios at the city of [[Sunaion]] in an effort to strike the Swords of Sanghelios by attacking the state of [[Vadam]]. However, the Arbiter learned of 'Mdama's Covenant plot and the Swords of Sanghelios created a forward operating base at [[Nuusra]] near the city, where they moved to attack 'Mdama's Covenant at Sunaion which resulted in the [[Battle of Sunaion]]. The battle marked a fatal blow to Jul 'Mdama's Covenant.<ref name="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]]}}

At one point, a human-Sangheili "librarian" team began to research archived Covenant records on the planet.<ref name="catalog"/>

On [[2558#October|October 28, 2558]] the Swords of Sanghelios emerged victorious over Jul 'Mdama's Covenant at the [[Battle of Sunaion]].{{Ref/Level|Halo 5: Guardians|[[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 must've 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|[[Halo: Bad Blood]]|Chapter=1}}

A harsh planet, Sanghelios is located on the innermost edge of the [[Urs system]]'s habitable zone,<ref>'''Halo Encyclopedia''', ''page 130'' (2011)</ref> allowing for a wide variation in vegetation and temperature on the planet.<ref name="HE311"/> With a diameter of {{Convert|15038|km|mi}},<ref name="universe"/> Sanghelios has a gravity of 1.375 Gs and an average surface temperature of -5&nbsp;°C to 96&nbsp;°C (23&nbsp;°F to 204.8&nbsp;°F). The planet has a diameter of 15,038 kilometers, making it larger than Earth. The land masses and continents are more scattered in relation to bodies of [[water]].<ref name="bestiarum"/> Sanghelios' sky varies in hue from a bright yellow to a blood red, due to large amounts of suspended particles in the upper atmosphere, but can also be blue. The planet's harsh and capricious environment is caused by Sanghelios' three suns, [[Urs system|Urs]], [[Fied]], and [[Joori]].<ref name="HE311"/> Like Earth, its atmosphere consists of [[oxygen]], [[argon]], and [[nitrogen]], but also has a reddish hue to it. Water on the planet can have various hues which include blood red, orange, yellow, cyan, blue and even purple or magenta.<ref>'''[[Halo 5: Guardians]]'''</ref> The surface of the planet is mostly composed of water, though Sanghelios has five individual continents: [[Kaepra]], [[Qivro]], [[Tolvuus]], [[Vaardma]], and [[Yermo]].<ref name="universe"/>

[[File:Halo 5 Sanghelios map.png|thumb|right|250px|A map of the planet.]]

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 name="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 name="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}} Frigid winds from the south pole of Sanghelios were spread across the southern regions of the planet.{{Ref/Novel|Halo: Broken Circle|Page=35}}
