Sanghelios is the fourth planet in the [[Urs system]], a [[Wikipedia:Star_system#Triple_star_systems|triple star system]] containing [[Urs system|Urs]], [[Fied]], and [[Joori]]. The planet is orbited by two [[natural satellite]]s, [[Qikost]] and [[Suban]].{{Ref/Reuse|bestiarum}} Sanghelios is a world with a very militaristic and feudal society, a result of the planet's harsh environment.{{Ref/Book|Id=HE311|Enc11|Page=311}}

As a space-faring species, the Sangheili have colonized multiple worlds in addition to Sanghelios as they expanded the reach of their own civilization and later the empire of the [[Covenant]].<ref name="11th 2">'''[[Eleventh Hour reports]]''', ''Report 2''</ref> Though the Sangheili have colonized dozens of independent worlds, Sanghelios still remains central to the government and culture of the species.{{Ref/Site|Id=sangheili waypoint|D=01|M=6|Y=2020|URL=https://www.halowaypoint.com/en-us/universe/species/sangheili|Site=Halo Waypoint|Section=Universe, Species|Page=Sangheili|LocalArchive=https://archives.halopedia.org/waypoint/www.halowaypoint.com/en-us/universe/species/sangheili.html}} Following the [[Human-Covenant War]] and the dissolution of the Covenant, Sanghelios had become embroiled in a civil war known as the [[Blooding Years]] that encompasses most of the planet and many [[Sangheili colonies]].{{Ref/Reuse|universe}} Though the [[Swords of Sanghelios]] have effectively taken control of the planet, many other factions seek to overthrow the government.{{Ref/Reuse|swords of sanghelios}}

==Overview==
===Topography===
[[File:H5-EnemyLines-Ruins1.jpg|thumb|left|250px|A Sanghelios cliffside, with ruins carved into it.]]
A harsh planet, Sanghelios is located on the innermost edge of the [[Urs system]]'s habitable zone,{{Ref/Book|Enc11|Page=130}} allowing for a wide variation in vegetation and temperature on the planet.{{Ref/Reuse|HE311}} With a diameter of {{Convert|15038|km|mi}},{{Ref/Reuse|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/Reuse|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/Reuse|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/Reuse|universe}}

[[File:Halo 5 Sanghelios map.png|thumb|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/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}}

====Ecology====
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}}

==History==
===Ancient history===
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}}

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>

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

===The Former Age===
{{Main|The Former Age}}
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}} 

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]], an area of the planet experienced a climate shift, and the Sanghelios launch towers were abandoned. Over time, the Sangheili on Sanghelios developed their technology and became a space-faring race, subsequently colonizing several worlds.{{Ref/Site|Id=surfacefeatures|D=08|M=11|Y=2020|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-surface-features|Site=Halo Waypoint|Section=News, Canon Fodder|Page=Surface Features|LocalArchive=https://archives.halopedia.org/waypoint/www.halowaypoint.com/en-us/news/canon-fodder-surface-features.html}}{{Ref/Site|Id=warzonefirefight|D=18|M=8|Y=2016|URL=https://www.halowaypoint.com/en-us/games/halo-5-guardians/updates/warzone-firefight|Site=Halo Waypoint|Section=Games, Halo 5: Guardians, Updates|Page=Warzone Firefight}}

Shortly before the War of Beginnings, 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|BC|Page=30}}

===War of Beginnings===
{{Main|War of Beginnings}}
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|CH|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|BC|Page=58}} [[Battle of Sanghelios|Part of the war]] was fought on Sanghelios, beginning sometime prior to [[855 BCE]] and only ending when the war ended in [[852 BCE]].{{Ref/Book|Id=Enc22P191|Enc22|Page=191}}
[[File:Thereturntraining.jpg|left|thumb|250px|The future [[Unidentified Sangheili Shipmaster (Righteous Vigilance)|Shipmaster]] of the [[Fleet of Righteous Vigilance]], duelling with a fellow clanmate on Sanghelios.]]
===Covenant Era===
In [[852 BCE]], the two races signed a treaty known as the [[Writ of Union]] to form the early Covenant.<ref>'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 30''</ref> However, [[851 BCE|the following year]], a [[Sanghelios civil war|civil war]] began on Sanghelios. Numerous 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|BC|Page=37}}

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}}

During the [[Human-Covenant War]], many Sangheili warriors from Sanghelios joined the Covenant's campaign against [[human]]ity until the [[Great Schism]].{{Ref/Reuse|HE311}}

[[File:HM-BloodingYears.jpg|thumb|250px|The [[Siege at Kolaar]] in [[2553]].]]
===Postwar===
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|H3|[[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|BC|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/Reuse|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/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]]}}
[[File:HINF Concept GuardianRising.jpg|250px|thumb|left|A Guardian on Sanghelios.{{Ref/Book|Enc22|Page=195}}]]
At one point, a human-Sangheili "librarian" team began to research archived Covenant records on the planet.{{Ref/Reuse|catalog}}

====Created uprising====
{{Main|Created uprising}}
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}}

By 2559, the Created had taken control of the planet. An administrator was installed to a position of power. All [[keep|keephold]] forces were disarmed and disbanded and local security was to be handled by [[armiger]]s. Three days after the [[Razing of Oth Sonin]], a [[High Gathering]] was held between Arbiter Thel 'Vadam and several [[High Kaidon|high kaidon]]s. Here, the Arbiter proposed the [[Concert of Worlds]], a formal alliance between all Sangheili planets, including Sanghelios. However, the lack of commitment seen at the meeting led the Arbiter to suspect that many of the high kaidons were placing their own interests above the need to stand strong and united against the threats of the [[Jiralhanae]], [[Kig-Yar]], mercenaries, and even [[San'Shyuum flotilla|vestiges]] of the [[San'Shyuum]].{{Ref/Novel|Out|Chapter=1|Quote=Perhaps the high kaidons wanted the Sangheili to remain divided and weak. That was the only explanation Arbiter Thel ‘Vadam could imagine for their squabbling and intransigence, for putting their own interests above the need to stand strong and united. Did they truly expect the Tyrant’s “peace” to protect Sangheili space from the encroachments of the Jiralhanae and the Kig-Yar?}}

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 was once led by an [[Arbiter]], a title that was part king and part judge.{{Ref/Reuse|h2a terminal 6}} During the early years of the [[Covenant]], Sanghelios was governed by the [[Council of City States]].{{Ref/Reuse|bc26}} The planet was initially used as the capital of the [[Covenant]], until the mobile city of [[High Charity]] completed construction in [[648 BCE]]. Afterwards, Sanghelios returned to Sangheili exclusivity, though the planet remained under the Covenant's control and served as a central world in the empire's dominion.{{Ref/Reuse|universe}} After the beginning of the [[Great Schism]] and the Covenant's resulting dissolution, Sanghelios' states briefly remained divided. However, during the ensuring [[Blooding Years]], a civil war in which numerous Sangheili clans and factions battled for dominance over Sanghelios and the Sangheili species, the [[Swords of Sanghelios]] effectively became the single world government for the planet. Led by Arbiter [[Thel 'Vadam]] and a grand council of kaidons, the Swords of Sanghelios attempted to quell any faction that attempted to seize control of the planet for themselves.{{Ref/Reuse|swords of sanghelios}} [[Rear Admiral]] [[Horatio Temkin]] served as the [[United Nations Space Command]]'s ambassador to Sanghelios in [[2558]].{{Ref/Comic|HEsc|Issue=5}}

===Culture===
Culture on the planet is based around a type of feudal manorialism with [[Sangheili]] on Sanghelios live in tightly-knit [[clan]]s.{{Ref/Reuse|sangheili waypoint}} Outside the cities, some of which feature towering structures of both classic Sangheili and [[Covenant]]-era designs,{{Ref/Reuse|urbanOntom}}{{Ref/Novel|BC|Page=47}} Sanghelios' landscape has stayed mostly unchanged for several millennia; the terrain is primarily agricultural, and the [[keep]]s typically follow ancient, pre-Covenant architectural styles.<ref name="gl57">'''Halo: Glasslands''', ''page 57''</ref> Those who committed crimes against the government may have been allowed to fight to the death in an arena. During the Sangheili's long service with the Covenant, the Covenant had a large presence on the planet.{{Ref/Novel|BC|Page=174}} [[Clan]]s and cities were allowed to develop in isolation, but any individual who renounced Sanghelios or rebelled against the government could face imprisonment or [[Capital punishment|execution]].{{Ref/Novel|BC|Page=125}}

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}}

==Trivia==
{{Linkbox|gallery=yes}}
*The name "''Sanghelios''" comes from the Latin ''sanguis'' and the Greek ''helios'' meaning "Blood-Sun". It is implied that this may refer to the emphasis on [[blood]] in the culture of the warrior Sangheili that live there.
*The ''Doctor Who'' episode "[[Wikipedia:Planet of the Dead|Planet of the Dead]]" features a planet called ''San Helios'', which is also part of a triple star system.<ref>[[Tardis:San Helios|San Helios]] at TARDIS Index File, ''Doctor Who'' wiki</ref>
*In ''[[Halo: The Cole Protocol]]'', Sanghelios is mistakenly referred to as "Sanghelion" in chapter headings.<ref>'''Halo: The Cole Protocol''', ''pages 88, 349''</ref>
