During the [[Forerunner-Flood war]], [[Master Builder]] [[Faber]] placed Installation 07, along with the other eleven rings in the original Array, under control of the [[Contender-class artificial intelligence|Contender-class AI]] [[05-032 Mendicant Bias|Mendicant Bias]], and one of the primary extensions of the AI was placed on the ring.<ref name="prim190">'''Halo: Primordium''', ''page 190-192''</ref> At one point, the Master Builder broke his deal with the [[Librarian]] and began to use the human specimens on the ring for his brutal experiments on the [[Flood]].

Faber also forcibly drafted [[Warrior-Servant]]s as an additional security force for the installation. In their exhaustive experiments, the Master Builder's researchers found that the majority of humans were apparently immune to the Flood, which they believed to be a result of a "cure" developed by [[prehistoric human civilization|early humanity]] during the ancient [[Human-Flood war|human-Flood conflict]]. In reality, no cure ever existed and the humans' apparent immunity was the result of the Flood's ongoing strategy to target Forerunners only.<ref>'''Halo: Primordium''', ''page 364''</ref>

Faber's researchers believed that a cure to the Flood might be found via extracting ancestral memory imprints from humans who carried the Librarian's special [[geas]]. Since the human specimens on the installation lacked these imprints, Faber, against the instructions of the Librarian and the [[Ecumene Council]], ordered his forces to gather humans from the Librarian's special population on [[Earth]] and transplant them to Installation 07. Consequently, both the installation's own human specimens and humans from Earth would be used in the Master Builder's experiments,<ref name="prim190"/> in what the humans came to know as the "[[Palace of Pain]]"; however, the "palace" was not in fact a single location as the humans believed, but many [[Flood research facility|Flood research facilities]] across the ring, most of them being re-purposed Lifeworker biological research stations.<ref name="p357">'''Halo: Primordium''', ''page 357-358''</ref>

After Installation 07 had been officially considered missing for 43 years, the Master Builder had the ring transported to the primary [[San 'Shyuum]] world [[Janjur Qom]] and authorized its activation to suppress [[Battle of Janjur Qom|a rebellion]], wiping out all but few of the San 'Shyuum. However, he failed to foresee the consequences of this decision. Immediately following the firing, many of the [[Warrior-Servant]]s and [[Lifeworker]]s assigned to serve under Faber's [[Builder]] forces openly rebelled against the Master Builder, viewing his actions as a grave offense against the [[Mantle]]. This rebellion was, for the most part, violently suppressed by Faber's [[Builder Security]] forces and the remaining Warriors and Lifeworkers were given a choice to either serve Faber or be killed. Some chose to ally with the Master Builder while those loyal to the Council continued to resist, sabotaging power stations and other facilities in an attempt to cripple the installation from within.<ref>'''Halo: Primordium''', ''page 305''</ref>

Once the news of Faber's use of the installation against the San 'Shyuum reached the Ecumene Council, Faber was arrested and put to trial in the Forerunner [[capital]]. The other eleven Halo rings were gathered in orbit over the capital, while Installation 07 remained missing after the incident at Janjur Qom.<ref>'''Halo: Cryptum''', ''page 282''</ref>

During Faber's trial, Installation 07 appeared over the capital. The rampant Mendicant Bias managed to subvert its other extensions on five of the remaining Halo rings, and cripple the capital's forces, while releasing the Master Builder from captivity. However, the emergent [[Bornstellar Makes Eternal Lasting|Bornstellar]]-[[Didact]] used a control code to temporarily stun Mendicant Bias, which allowed the capital's defenses to respond to the attack and assault the Halos under Mendicant Bias' control.<ref name="cryptum">'''Halo: Cryptum''', ''page 300-316''</ref> The capital's fleets opened fire on Installation 07, while the Halo's [[sentinel]]s and the Master Builder's ships attempted to defend it.<ref name="cryptum"/> Many of the ships involved in the battle were destroyed and crashed across the ringworld.<ref>'''Halo: Primordium''', ''page 304''</ref> Despite the installation taking heavy damage, Mendicant Bias successfully activated the ring's main weapon at the conclusion of the battle, presumably wiping out all life in the capital system.<ref name="p272"/>

Following the battle at the capital, Installation 07 retreated into a [[slipspace portal]], reappearing in a distant star system near the galaxy's edges.<ref>'''Halo: Primordium''', ''page 273''</ref> This was part of a security measure beyond Mendicant Bias' control – in order to prevent the ring from falling in the wrong hands, it had been programmed to enter a course which would result in a collision with [[Wolf-faced planet|a planet]] in several days.<ref>'''Halo: Primordium''', ''page 279''</ref> As the primary, automated control systems had been sabotaged,<ref name="p320">'''Halo: Primordium''', ''page 320''</ref> the Primordial and Mendicant Bias were unable to direct the Halo's movements. Instead, they began to gather humans in a last-ditch effort to use them to manually steer the ring away from its destructive course.

After its successful retreat, Installation 07 began automated measures to repair the damage it had taken. Over the next few days, entire plates of the ring's superstructure were replaced and rebuilt.<ref>'''Halo: Primordium''', ''page 76-78''</ref> However, the installation was still low on power due to many of the power stations being down, and entire sections kept experiencing power outages.<ref name="p194">'''Halo: Primordium''', ''page 194-197''</ref> Meanwhile, the Halo's human and Forerunner occupants were caught amidst the chaos. Mendicant Bias used its all-encompassing control to corrupt most ancillas and [[Forerunner personal armor|Forerunner armors]] on the ring, turning the armors into death-traps for their wearers. This forced Forerunners on the installation to remove their armor in order to survive.<ref>'''Halo: Primordium''', ''page 186''</ref>

The Lifeworker beacons across the installation, used to transmit orders to the local humans via their [[geas]], were giving conflicting commands which kept changing as the various factions fought for control of the beacons.<ref>'''Halo: Primordium''', ''page 184''</ref> Similar beacons were used to transmit orders to Lifeworkers and their ancillas across the ring, and although they believed the orders came from the Librarian, there was no definite certainty of this. Acting under these orders, a Lifeworker known as [[Genemender Folder of Fortune]] extracted and stored the consciousnesses and ancient personality imprints of any humans he found, doing the same to himself, believing it would save him from having to serve the Master Builder.<ref name="p194"/>

During the battle above the capital, two Earth humans, [[Chakas]] and [[Riser]], who had been captured by Faber and were aboard ships headed to Installation 07, crashed in different parts of the ring. Chakas landed near a village, where a young woman known as [[Vinnevra]] found him and later took him to see her grandfather, [[Gamelpar]], who had been brought on the ring from Earth by Faber's minions long ago. The group then proceeded to travel under the guidance of Vinnevra's geas, which had activated upon Chakas' arrival, but upon arriving at the destination, they discovered it to be a "Palace of Pain", where the Primordial itself and a number of [[war sphinx]]es were herding numerous humans inside. After traveling in the opposite direction for several days, the group reunited with Riser, who had landed in a Flood-infested region nearby. Eventually, they came across a rail transport which brought them to Lifeworker Central, where a monitor instructed them to enter another transport.<ref>'''Halo: Primordium''', ''page 266-273''</ref>

The humans were then taken to the facility where Mendicant Bias' core was housed. There, humans from Earth were separated from the Tudejsa, and their ancestral personality imprints were removed by Mendicant Bias and the Primordial. They were given a choice to cooperate with Mendicant Bias and have their revenge against the Forerunners for [[Human-Forerunner War|destroying their civilization]] ten thousand years earlier; however, they would first have to help save the Halo from colliding with the approaching planet. Those who accepted Bias' offer were sent to various control stations spread out across the Halo, including the [[Cartographer]].<ref name="p320"/> However, humans alone did not possess the knowledge necessary to properly interface with the ring; instead, Flood-infected Forerunners processed by the Composer were brought in and connected with each human to the Halo's control systems.<ref>'''Halo: Primordium''', ''page 328''</ref> As Installation 07 approached the planet, the controllers successfully managed to reorient the ring in a way the planet would pass through the center; this way, the ring would take heavy damage but had a chance of surviving.

Despite this, there was still a grave risk that the gravitational pull of the planet would tear the Halo apart. Plates of foundation material were moved over the exterior walls in preparation for repairs during the passage. Sentinels and other craft were positioned across the Halo, firing their engines in an attempt to alter the installation's course, with little success. The Halo's central [[hard light]] hub and spokes, typically used in the activation process of the main weapon, were activated to slow down the ring's passage over the planet, and to borrow some of the planet's velocity in order to alter the ring's orbit in an effort to prevent collisions in possible future orbital passes. However, the hard-light structures did not last long against the planet's surface, disintegrating shortly after the impact. The installation's outer walls quickly exceeded their capacity to manage the strain of the planet's tidal stresses, coming apart at various points. As the walls gave way, the foundational plates began to bend and distort, with massive gaps–some of them hundreds of kilometers in diameter–opening between them.<ref name="p333">'''Halo: Primordium''', ''page 333-346''</ref>

By [[2557|June 2557]], the [[Office of Naval Intelligence]] had managed to perform a cursory examination of Installation 07, discovering its size and deducing that its surface was overrun by a perpetual cloud cover, although information on the ring remained sparse.

==Topography==
===Structure and construction===
[[File:1211311398 Installation 01.jpg|250px|thumb|The symbol representing Installation 07.]]
The depth of Installation 07's ground layer before the foundation material below, at least in some areas, was approximately 800-900 meters.<ref>'''Halo: Primordium''', ''page 97''</ref> As with the rest of the Halos, the upper layers of the plate foundation were shaped to accommodate the terrain formations that would be laid over them.<ref name="p318">'''Halo: Primordium''', ''page 318''</ref>
 
During the skirmishes surrounding the [[Battle of the Capital]], the terrain on the Halo was destroyed in many areas, leaving the bare foundation exposed. In addition, large gaps had been burned into the foundation itself during the battle around the Capital.<ref>'''Halo: Primordium''', ''page 112''</ref> Some of these damages was deemed extensive enough to remove and replace entire sections of the ring's foundational plate, with the Halo held together by its edge walls and possible field reinforcement during the operation. The replacement plates were moved from the Halo's exterior, transported over the inner portion of the ring and eventually placed in the missing sections.<ref>'''Halo: Primordium''', ''pages 71-72, 76-77''</ref> In less damaged areas, building up the foundation from within the ring's interior was sufficient for repairs. A ditch in the landscape, for example, would be closed by the foundation gradually rising from below.<ref>'''Halo: Primordium''', ''page 105''</ref>
 
Entire complexes of structures—some of them thousands of meters tall—had been destroyed; due to the ring's limited power, their basic [[hard light]] frameworks would continue to flicker on and off erratically, attempting to rebuild themselves.<ref>'''Halo: Primordium''', ''pages 114, 116''</ref>
 
===Ecology and environments===
[[File:Halo ring 6.png|thumb|250px|The surface of Installation 07 in 2552.]]
As a sanctuary of Lifeworker specimens like the rest of the Halos, Installation 07 was home to numerous transplanted species of flora and fauna from various worlds, including life native to [[Earth]].<ref name="p57">'''Halo: Primordium''', ''page 57''</ref> These included bees,<ref>'''Halo: Primordium''', ''page 43''</ref> mosquitoes,<ref>'''Halo: Primordium''', ''page 164''</ref> rabbits<ref name="p57"/> and edible scorpions larger than [[Chakas]] had seen in his home region of [[Marontik]].<ref>'''Halo: Primordium''', ''page 41''</ref> Installation 07 had not been fully finished by 100,000 BCE; when complete, it would have accommodated even more transplanted beings.<ref name="p318"/>
 
Among its vast amount of different flora the ring was home to one peculiar type of enormous tree with thick thorns that made passage impossible in forests where the trees were thickly spaced. The trees' trunks were brown and green, and several meters thick. Ten or twelve meters up the thorns were supplanted by tiny branches that formed a dense canopy.<ref>'''Halo: Primordium''', ''pages 127-128''</ref> Several hours before dawn, the spikes would withdraw into the trunks, allowing passage through the forest, thrusting out again at first light. A forest of these trees was traversed by Chakas, Vinnevra and Gamelpar during their journey on the ring; the trio made it out just in time before the dawn.<ref>'''Halo: Primordium''', ''pages 129-132''</ref>
 
On the other side of the forest there was a salty ocean spanning the width of the ring.<ref>'''Halo: Primordium''', ''pages 132-133, 246''</ref> The sea was home to massive aquatic creatures smooth and gray in general aspect with fins and rounded, blue and purple appendages edged with lobes branching off into sets of smaller and smaller lobes. The flesh that comprised the lobes resembled milky glass full of bubble-like jewels. These creatures observed Chakas, Vinnevra and Gamelpar for hours while they crossed the ocean in a wooden boat but did not attack.<ref>'''Halo: Primordium''', ''pages 158-160''</ref>
 
On the other side of the ocean was a dense, humid jungle<ref name="p168">'''Halo: Primordium''', ''pages 168-169, 172''</ref> with terrain that gradually rose from the shoreline into a plateau and a mountain range.<ref name="p213">'''Halo: Primordium''', ''page 213''</ref> This area was a Lifeworker special reserve and housed [[Genemender Folder of Fortune]]'s station.<ref name="p168"/> Several hundred kilometers inland away from the mountains was a large region where terrain had been stripped away, leaving only bare foundation material for four or five thousand kilometers.<ref name="p213"/> This damaged portion terminated in an area covered in a thick coat of inert [[Flood spore]] powder generated by [[spore peak]]s that had formed there after a localized outbreak.<ref>'''Halo: Primordium''', ''pages 218-219, 223''</ref> The region was shrouded by a perpetual storm.<ref name="p213"/>
 
To better grasp directions on the Halo, Chakas devised his own system of terms: ''inland'' or ''inward'' for away from the nearest edge wall and ''outland'' or ''outward'' toward the opposite wall. "East", he decided, was the direction of the local "sunrise" while west was where the sun "set".<ref>'''Halo: Primordium''', ''page 81''</ref> Meanwhile, the [[Tudejsa]], who had acclimatized to life on the ring as opposed to Earth, used their own words to describe directions, including ''lightwise'', ''crosswise'' and ''turnwise''.<ref>'''Halo: Primordium''', ''page 83''</ref>
 
===Astronomy===
Shortly after completing its jump away from the Capital, the Halo's spin slowed down and the ring began to [[Wikipedia:Precession|precess]].<ref>'''Halo: Primordium''', ''page 44''</ref> While in the refuge system on its way to collide with the [[wolf-faced planet]], Installation 07 still maintained a day-night cycle of sorts with a noticeable axial tilt relative to the local star. The Halo rotated in a way that the local sun would first fall behind one of the edge walls lining the band,<ref>'''Halo: Primordium''', ''page 148''</ref> then pass behind the other side of the ring, reappearing at dawn from the top of the opposite edge wall. Dawn was preceded by the illuminated portion of the ring's terrain growing closer further up the band while the shadow receded. The orange glow of dawn would be partly reflected to some areas still in the shadow of either the other side of the ring or the edge walls.<ref>'''Halo: Primordium''', ''page 73''</ref> At "noon", the sun would pass through the middle of the opposite side of the ring directly above the observer—termed the "sky bridge" by Chakas.<ref>'''Halo: Primordium''', ''page 171''</ref>
 
===Locations and systems===
;[[Cartographer]]
Installation 07's primary mapping facility was an enormous structure extruding from one of the edge walls.<ref>'''Halo: Primordium''', ''pages 319-320''</ref>
 
;Lifeworker Central
The nexus of Lifeworker operations on the installation, Lifeworker Central<ref>'''Halo: Primordium''', ''page 266''</ref> was a large structure with a cavernous interior built near a body of water with rocky cliffs several kilometers on the other side. Like many other locations on the ring, the hard light structures within were suffering frequent power outages and flickering uncontrollably. The Central was accessible via a rail transit system as well as anti-gravity gondolas on the waterfront.<ref>'''Halo: Primordium''', ''page 268-269''</ref>
 
;[[Flood research facility|Flood research facilities]]
Known to the local humans collectively as the "[[Palace of Pain]]", these facilities were the thousands of former Lifeworker biological stations converted into Flood research centers by the [[Faber|Master Builder]]. In practice, they were under the administration of [[Mendicant Bias]], working under the [[Primordial]]'s instructions.<ref name="p357"/> One of these research facilities was an enormous square pillar leaning against one of the edge walls, its top obscured by clouds.<ref>'''Halo: Primordium''', ''page 106''</ref> The Primordial personally observed crowds of humans—made docile by controlling their ''geas'' via beacons—being herded into the structure by [[war sphinx]]es.<ref name="p109"/>
 
;Lifeworker preserves
The [[Lifeworker]]s maintained many outposts and reserves across the ring where they monitored and tended to the local life.<ref name="p168"/> Genemender Folder of Fortune's station was located in what appeared to be a primitive human village, the Forerunner technology of the outpost itself hidden by a [[dazzler]] or [[baffler]].<ref>'''Halo: Primordium''', ''page 174-175, 186''</ref>
 
;Lifeworker beacons
Beacons were ovoid-shaped devices found across the ring used by the Lifeworkers—or whoever controlled them—to give humans and other beings seemingly instinctive instructions through their ''geas''.<ref name="beacon">'''Halo: Primordium''', ''pages 88-89''</ref><ref name="p184"/>
 
;Power stations
The ring was home to a number of power stations, many of which were sabotaged by the Warriors who rebelled against the Master Builder during the crisis at the Capital.<ref name="p305"/> A dark gray conical structure 300-400 meters tall was assumed to be a power station by Chakas, who had seen similar structures on Erde-Tyrene.<ref>'''Halo: Primordium''', ''page 161''</ref>
 
;Mendicant Bias' core
The primary extension of Mendicant Bias was housed in a massive facility deep beneath Installation 07's surface, accessible via anti-gravity gondolas which traveled through an enormous, 20-30-kilometer-diameter circular opening in the ring's landscape. After passing through an undetermined void within the ring's bowels, the transit vehicles settled in an enormous chamber whose floor was a green-glowing maze of hard light paths resembling a spiderweb.<ref>'''Halo: Primordium''', ''pages 278-283''</ref> Mendicant Bias itself was based in a mobile structure featuring its core crystals and a large green eye, moving on legs of hard light.<ref>'''Halo: Primordium''', ''page 287-288''</ref> It was here that the humans were eventually gathered and thoroughly examined by Mendicant Bias before the final effort to cancel the ring's failsafe orbit.<ref>'''Halo: Primordium''', ''page 288''</ref>
 
;Rail transit system
A form of transport not observed on the other Halo installations, this form of conveyance consisted of high-speed cars hanging from a rail that floated in the air with no visible support.<ref>'''Halo: Primordium''', ''page 252''</ref> There were poles spaced at long intervals but the railing did not physically touch the pole, instead going through a wide circle on top of it.<ref>'''Halo: Primordium''', ''page 257''</ref> The cars were largely featureless on the inside and were capable of combining, reconfiguring and compartmentalizing their interiors to accommodate different passengers; after completing their journey Chakas and his human companions were shocked to learn that their car had been shared by [[Composer]]-processed Flood victims in a different compartment.<ref>'''Halo: Primordium''', ''pages 265''</ref> The wagons were equipped with an [[ancilla]] who could provide refreshment—water and a nutritional paste—at the occupants' request.<ref>'''Halo: Primordium''', ''pages 262-263''</ref>
 
;[[Anti-gravity gondola#Installation 07|Anti-gravity gondolas]]
Like many other Forerunner installations, Installation 07 featured a unique type of anti-gravity gondola or "boat". Unlike many other gondolas which follow linear paths, these vehicles could traverse rather long and complicated routes, including one from Lifeworker Central to Mendicant Bias' core.<ref>'''Halo: Primordium''', ''page 277''</ref>
 
;Human settlements
The home village of Vinnevra and Gamelpar was located near one of the ring's edge walls.<ref>'''Halo: Primordium''', ''page 39''</ref> It was a collection of huts situated on a flat plain of dry grass and dirt several hundred meters from the tree line.<ref>'''Halo: Primordium''', ''page 37''</ref>
 
There was also old Tudejsa city some distance inland from the village. The humans abandoned the settlement after the Forerunners began to abduct humans for experiments. The city reminded Chakas of [[Marontik]], though he noted it may have been older<ref>'''Halo: Primordium''', ''page 36''</ref> and more populous.<ref name="p84">'''Halo: Primordium''', ''pages 84-85''</ref> The city was lined by a large wall with mud and rock ramparts designed as a defense against raiders from other cities or roving bands. A single wooden gate on the western side allowed passage inside; the entrance tunnel was approximately 20 meters long.<ref>'''Halo: Primordium''', ''pages 82-83''</ref> Much like Marontik, the city was home to motley stone and mud buildings with wooden supports no more than tree stories tall and with no particular concern for aesthetics. Cobble or dirt streets and alleys crisscrossed between the buildings. By the time Chakas, Vinnevra and Gamelpar visited the city, it had been raided of any valuables long prior.<ref name="p84"/> Likewise, the city was almost entirely devoid of life, including mosquitoes or waterborne larvae.<ref>'''Halo: Primordium''', ''page 90''</ref> The city's market was home to one of the Lifeworkers' beacons, camouflaged by Forerunner technology.<ref name="beacon"/>
 
About a kilometer off the shores of the ocean crossed by Chakas and his compatriots there was a human city based on wooden platforms supported by stone pillars and only accessible via water.<ref name="p135">'''Halo: Primordium''', ''page 135''</ref><ref>'''Halo: Primordium''', ''page 139''</ref> A network of bridges, platforms, docks and other wooden structures crisscrossed between these pillars,<ref name="p135"/> becoming denser toward the settlement's center.<ref>'''Halo: Primordium''', ''page 142''</ref> The largest building had a layout the shape of a peaked pentagram and was home to a large hall with impressively intricate carvings in its [[door]].<ref>'''Halo: Primordium''', ''page 144''</ref> During the skirmishes on the ring, this city was the site of a battle between hundreds of Forerunners whose corpses would remain scattered across the area; no humans—alive or dead—were present at this point. The Forerunners had imprisoned a [[proto-Gravemind]] in an energy cage placed inside the hall of the central building.<ref>'''Halo: Primordium''', ''page 150-152''</ref>
