'''Forerunner''' is the translated name for an ancient race of enlightened beings that were the creators and builders of the Halos, [[the Ark]], and the [[Shield World]], [[Onyx]], along with the artifacts that were found on the planets [[Reach]], [[Earth]], [[Sigma Octanus IV]], [[Harvest]], and [[Arcadia (Planet)|Arcadia]]. All that is known about the Forerunner has been gleaned from these various artifacts. The predecessors of the Forerunner are thought to be another alien race known as the [[Precursors]]. The alien faction known as the [[Covenant]] worshipped the Forerunners as gods, deriving much of their technology from Forerunner artifacts found throughout the galaxy.<ref>''[[Halo: The Flood]]'', From the experiences of [[John-117]], the Master Chief, the Covenant do not fully understand the Forerunner. This is evident when they mistranslated the Glyph "Reclaimer" as "Reclamation"</ref>

==Known History==
Next to nothing is known about the Forerunners, except that they were an advanced civilization, coming to power after the disappearance of another race, known to them as the [[Precursors]]. The Forerunners reached their peak before activating the [[Halo Array]] around 100,000 years ago, exactly as planned (as explained by [[343 Guilty Spark (Monitor)|343 Guilty Spark]] in [[Halo 2]]). <ref>''Halo 3 Limited Edition'' - [[Bestiarum]]</ref>

The Forerunners were highly technologically advanced during their reign; some speculated that the ancient faction had the ability to accelerate a species stage development (of course, this is only speculation). Being the ''only'' known race ever to achieve Tier 1 technology based on the [[Technological Achievement Tiers]] measurement, they were only superseded by the mysterious Precursors at Tier 0; evidence of which has been found on various planets. The fact that the Halos were scattered around the galaxy also hints at the possibility that the Forerunner empire covered most, if not all, of the galaxy. It has also been hinted at in the [[Terminals]] that the Forerunners received their "[[Mantle]]" from the coinciding "[[Precursors]]". 

Later in their history, a Forerunner survey team came into contact with an extra-galactic parasite known as the [[Flood]] on the planet [[G 617 g]] (details of this first contact are unavailable). After this first contact, the Forerunner realized the great danger that the Flood posed to the entire galaxy and attempted to contain them. The attempt to contain the Flood was a failure, primarily because in the beginning, they treated the Flood as a disease, attempting to contain it and quarantine it, instead of treating it as a severe threat and declaring an all out war on the Flood. They did not start war until it was far too late. <ref>[http://blog.ascendantjustice.com/halo-3/the-terminals/a-voice-from-the-tomb-i/]</ref>

When the Forerunners were unable to contain the Flood outbreak, war between the two factions broke loose. During the 300 years of conflict, the Forerunner studied the Flood in labs such as the gas mine located in the atmosphere of [[Threshold]], looking for some sort of weakness. Eventually they created the [[Halo]] Array, a weapon of last resort designed to starve the Flood to death by killing all sentient life with enough biomass to sustain them. <ref>''[[Halo: Combat Evolved]]'', 343 Guilty Spark</ref>

At first, the Forerunners were reluctant to use the Array. The [[Gravemind]] managed to convince a [[Contender-class Artificial Intelligence|Contender-class AI]], [[Mendicant Bias]], to unite with the Flood. Mendicant Bias soon led his massive fleet in an attack on the "Maginot Line", the final barrier between what the Forerunners could protect and what they had to let go. The Forerunner were given no choice but to activate the Halos, killing themselves and all life of sufficient biomass and cognitive ability in the Milky Way, with the exception of those species safely placed on [[the Ark]].

==Forerunner Technology==
Forerunner technology was highly cultivated and progressive. They managed to create solidified surfaces out of meticulous energy, construct a Halo-wide teleportation grid and create and utilize a plethora of other advanced gadgets. The [[Halo Rings]] themselves, the Micro-Dyson Mark II sphere, which is connected through a portal to the shield world [[Onyx]], and the Ark (Installation 00) are, above all others, the most significant pieces of Forerunner technology. The planet Onyx in particular demonstrates both their ability for engineering on a grand scale, and their near transcendent grasp of [[Slipspace]] technology. It is unknown how much of their technology is based on the technology of the Precursors. 

Covenant Luminaries (which are actually stolen Forerunner equipment designed to detect other Forerunner objects) can detect Humans, previously mislabeled as "Forerunner Artifacts", leading to the initial Human-Covenant contact which sparked a [[Human-Covenant war|seemingly endless war]].  Ironically, the Covenant worships the Forerunners but fight Humans, who may be Forerunner descendants based on the fact that they are detected by Luminaries.

[[Engineers]] are the only known Forerunner creation to be both non-robotic and to join the Covenant.

Forerunners have the technology to reproduce entire individuals from encoded DNA/RNA/silicon samples in data streams. This was mentioned in the [[Bestiarum]]: "''DNA/RNA/Silicon samples are encoded in this data stream. Reproduction of individuals for analysis is prohibited by this facility.''"

The Forerunner seem to be genetically identical to the humans, which can be corroborated by the Iris Server-05 message about the humans providing "answers" to the Forerunner's own "mysteries", and Mendicant Bias's own declaration in [[Halo: Contact Harvest]]. This also explains why the Prophets ordered the [[Covenant]] to exterminate humanity; knowing that they are the Forerunner's descendants.

===Weaponry===
[[Image:Forerunner AI.jpg|thumb|right|300px|A [[Sentinel]] and a [[Monitor]], Both are Forerunner creations with specific tasks.]]
Forerunner constructs and sentries use a broad variety of weapons, typically high-energy powered beams. These weapons proved to be very effective when battling the [[Flood]], burning them to the point that they cannot be revived by their [[Infection Forms|compatriots]]. The Forerunners installed and constructed these intricate beam weapons inside their paradigm Arrays, allowing them to build an army of machines to battle the Flood without sending any Forerunner into real battle. Forerunners made active use of plasma weaponry as well, as shown by the Covenant, whose weapons and technology are solely based off of Forerunner artifacts.

The [[Sentinels]] wield orange-colored directed energy beams, used primarily for fighting the Flood. [[Sentinel Majors]] however, have a more powerful and accurate version of the beam, which sports superior energy output, at the cost of overheating issues. These more advanced energy beams are colored blue. All varieties of these [[Sentinel Beams]] can be wielded by certain Covenant and Human infantry.

Meanwhile, [[Enforcers]] are equipped with multiple packs of small grenades, or mortar-like explosives launched over the top of their shield as well as a pair of [[Pulse Beam|Pulse Beams]], which fire clusters of smaller red projectiles or bolts of energy at an extremely fast rate, used mainly against infantry at close range. These mammoth constructs also seem to be able to lift vehicles using some sort of magnetic or anti-gravity grapple, before crushing even tank-sized objects between their massive 'arms'. The [[Constructors|Constructors']] repair beam can also be considered a weapon, but with minimal damage output.

The [[Onyx Sentinel|Sentinels of Onyx]] had significantly more powerful weaponry. They were described to be a sphere surrounded by three floating "booms", or small pieces of armor that had powerful energy shields that would suddenly "pop" into place in order to deflect objects moving at high velocities.<ref>''Halo: Ghost of Onyx''</ref> Their shields are not activated by slow-moving objects, such as rocks, which [[Team Saber]] used to destroy one of the Sentinels. Their energy weapons, described as a single golden beam that, although charged slowly, could melt straight through the armor of the Spartan-IIIs. The Onyx Sentinels also have the ability to combine energies, for different purposes, such as stronger combat abilities, or excavation purposes. Their powers are exponentially increased by this combination, and enough of them were able to combine to easily destroy two Covenant destroyers. However, the second Covenant Destroyer was caught off guard after a slipstream space jump, and the first one had its energy shields down.

The Forerunners also constructed [[Automated Turret|Automated Turrets]] that fire blue beams similar to those of sentinel majors. These turrets themselves resemble stripped-down sentinels, and hover in mid-air, tracking enemy targets, but are otherwise immobile.

In [[Halo 3]], it seemed that even the [[Monitors]] had the ability to defend themselves against the Flood using a focused beam similar to the Sentinel's beam, but much more powerful. [[343 Guilty Spark (Monitor)|343 Guilty Spark]] showed this ability in [[Floodgate]] and ''[[Halo (Halo 3 Level)|Halo]]''<ref>''Halo'' (''Halo 3'' Level)</ref>. The weapon was capable of draining the shields of a Spartan-II in one blast and mortally wounding Sergeant Major Avery Johnson. It is also quite odd and puzzling as to why [[2401 Penitent Tangent]] didn't use this ability against the [[Gravemind]] in ''[[Halo 2]]''. It is assumed that the Gravemind is likely to have damaged [[2401 Penitent Tangent]] when he captured the Monitor, disabling its beam weaponry. It could simply be that it was not equipped with one. Although, it is possible the Monitor attacked the Gravemind every chance he got, explaining his red "eye". With the Gravemind's size and power, it was probably never injured.

===Art and Architecture===
[[Image:Sacredicon1600.jpg|thumb|right|300px|The [[Library]], a classic example of Forerunner architecture.]]
Forerunner architecture is noted mainly for being large-scale and geometric in style, mostly triangular shaped when observed. The Forerunners had a habit of creating natural habitats, such as those of the Halo rings, which tend to be very elaborate, with numerous extrapolations of the basic design of a construct appearing to be purely decorative. That said, their distinctive beauty are not restricted to Halo Array network. The Aztec-esque stones of [[Cote D'Azur]], the arches and weathered inscriptions of Sigma Octanus IV, the intricate caverns and three-kilometer holographic dome beneath ONI's Reach complex, the ancient stepping-stones of the Grunt's homeworld, and the Forerunner City discovered in the depths of the human-inhabited [[Onyx]], all display the Forerunner's innovative architectures. Most Forerunner architecture is constructed with a special type of metal that resists deterioration, bullets, plasma bolts and fire, as evidenced by Forerunner structures standing in pristine condition 100,000-150,500 years after they were built. However their resistance to [[plasma]] fire is limited; in ''[[Halo: Ghosts of Onyx]]'' the [[Elites]] blasted a hole in a Forerunner wall with plasma weapons. In ''[[Halo 2]]'', [[Sgt. Avery Johnson]] destroyed the door to the control room of [[Installation 05 | Delta Halo]] with a [[Scarab]]. Other structures are constructed out of traditional materials, such as [[Onyx (material)|chalcedonic quartz]], which does not preserve nearly so well. These structures employ complex geometric shapes that appear to operate in dimensions higher than human understanding can comprehend.<ref>''[[Halo: Ghosts of Onyx]]''</ref> The Forerunners also decorated the interiors of their structures with a complex web of engraved straight lines and applied decorative touches and designs to nearly everything that they build, from structures to weapons. Even the Sentinel robotic drones possess small holographic Forerunner script around their "eyes".

Forerunner architecture distinguishes itself from Covenant structures in that they incorporate the use of angles, usually at extremely sharp degrees as the Forerunner buildings are usually triangular. Originally, the ideas and concepts on Forerunner structures and technology was that it would be sleek and curved to give it an advanced feel. However, [[Bungie]] wanted the structures to feel as if they could stand the test of time and redesigned them to be solid and monolithic. The smooth, near-organic design would later be adopted by the [[Covenant]] in their architecture, although they did not adopt the Forerunner tradition of decorating their structures with glyphs. In Halo Wars the Forerunner counting system is used to open and close portals on the last level.

===Forerunner Stellar Engineering===
{{Main|Stellar Engineering}}
While the Forerunners' architectural and technological prowess is legendary among the [[Covenant]] and [[UNSC]], their masterpieces also extended to the fields of stellar engineering. At least three Forerunner sites, the [[Shield World]]<ref>''[[Halo: Ghosts of Onyx]]''</ref> Onyx, the [[Installation 00|Ark]]<ref>''[[Halo 3]]'', ''[[The Ark (Level)|The Ark]]'' and ''[[Halo (Halo 3 Level)|Halo]]'' Levels</ref>, and the [[Micro Dyson Sphere]] that holds the Apex, made use of suns where none should exist. The Shield World existed permanently in [[Slipspace]], where solar systems outside of a Dyson Sphere cannot exist, and the Ark was located far outside of the galaxy where galactic material would have been insufficient to form the sun that illuminates the Ark.  The sun at the center of the Dyson Sphere where the Apex was housed was abnormally small, in order to accommodate the planet-sized Dyson Sphere. Whether these suns are artificially engineered or simply moved from another star system by the Forerunner is unknown: either would have been an enormous technological achievement. Another known Shield World is the planet discovered by the Spirit of Fire. This world had a outer crust like Onyx, but its inner Dyson sphere was accessed through a long narrow tunnel hidden under one of the planets oceans. Once through the tunnel, the Spirit of Fire had to pass through several "cleansing rings" in order to make it to the center of the planet. This Dyson sphere, unlike the Onyx Dyson sphere, was not separated in slipspace but was actually constructed on what appeared to be hollowed out inside of the planet. This sphere seemed to have had an artificially created sun like the one on the Ark.

The Ark is confirmed to be artificial, due to its unnatural "flower head" shape. It has been theorized to be an [[wikipedia:Alderson Disk|Alderson Disk]]. It is likewise unknown if these are the only stellar engineering achievements the Forerunners made; whether the systems that the [[The Halo Array|Halo Installations]] orbit are artificial or native to that region of space; whether other Shield Worlds exist; and how the construction or movement of such large stellar bodies was accomplished.

==Forerunner in Covenant Religions==
The [[Covenant]] venerate the Forerunners as gods and referred to them as the '''Ancients''', believing that the [[Halo Array]] elevated the Forerunner to godhood instead of killing them. As such, they have appropriated many Forerunner technologies and artifacts, and such searching led to the Covenant coming to Harvest in the first place, therefore beginning the Human-Covenant war. Also they dedicated a significant amount of time to the search for other "holy relics" such as the [[Halo Installations]], believing that they can follow the Forerunners into godhood. This is referred to as the "[[Great Journey]]" by the Covenant races. The [[Covenant]] believe that the Forerunner's ascension to godhood was finalized after the rings were fired.

==Known Forerunners==
*[[Librarian]]
*[[Didact]]
*[[Filial Devotion]]

==Trivia==
*The Forerunners seem to be similar to the Silver Race of Greek mythology. Similarly, the Forerunners are very similar to the Ancients in the Stargate series in that they both built technologically advanced rings as well as galactic scale weaponry, and are thought of as gods by aliens. They also went extinct thousands of years ago, and thought of humans as their children. They show some similarities (their highly advanced technology and the fact that they mysteriously vanished) to the [[Marathon (video game series)#The_Jjaro|Jjaro]], a race of aliens from a previous [[Bungie]] game,  ''[[Marathon (video game series)|Marathon]]'', the Eloh from the MMORPG ''[[Wikipedia:Tabula Rasa (video game)|Tabula Rasa]]'', the [[Wikipedia:Old Ones (Warhammer 40,000)|Old Ones]] from [[Wikipedia:Warhammer 40,000|Warhammer 40,000]], the Protheans in ''[[Wikipedia:Mass Effect|Mass Effect]]'', the [[Wikipedia:Precursor (Star Control)|Precursors]] of ''[[Wikipedia::Star Control | Star Control]]'', the [[w:c:starwars:Rakata|Rakata or Builders]] of ''[[Wikipedia:Star Wars|Star Wars]]'', the [[Wikipedia:Progenitors (Homeworld)|Progenitors]] of ''[[Wikipedia:Homeworld|Homeworld]]'', the Chozo and Alimbics of ''[[Wikipedia:Metroid|Metroid]]'', the [[Wikipedia:Ancients (Stargate)|Ancients]] of the ''[[Wikipedia:Stargate|Stargate]]'' television series, the Xel'Naga in ''Starcraft'', the [http://biosector01.com/wiki/index.php/Great_Beings Great Beings] of ''[http://biosector01.com/wiki/index.php/BIONICLE Bionicle]'', the Time Lords, of "Doctor Who", and most especially, the Krell of the film Forbidden Planet. The concept of a highly advanced extinct race leaving technological relics behind is not a new concept and has appeared in several other media such as books and films like Stanley Kubrick's 2001: A Space Odyssey. The Forerunner also bear a striking similarity to Larry Niven's Pak Protectors (''Ringworld'' Series), whom also built a Ring-like Station but disappeared, leaving the Ringworld to go off balance from its own sun.
*[[The Guardians]] are thought to be somehow related to Forerunners.
*The Forerunners were the main focus of the alternate reality game, ''[[Iris]]''.
*The holographic construct on [[Epitaph]] is said to be the Forerunner AI, Mendicant Bias.
*On the final level of [[Halo Wars]], 7 Forerunner numbers can be seen on the forcefield ground. When the forcefield is deactivated, the numbers go away.
*It was announced recently that a [[Forerunner Trilogy|trilogy of books]] based on the Forerunners culture and their war with the [[Flood]] will be written by [[Greg Bear]].
*In the last mission on ''[[Halo 3]]'' (''[[Halo (Halo 3 Level)|Halo]]'') in the cut scene before fighting the [[Monitor]], [[343 Guilty Spark (Monitor)|343 Guilty Spark]] says to the [[Master Chief]] "''You are the child of my makers. Inheritor of all they left behind. You are Forerunner.''" This has led to many fans concluding that Humanity and the Forerunner are one and the same, and various passages from the books support this. Another strong indicator is that Humans can activate and use Forerunner technology without dissecting and reverse engineering it. However the [[Terminals]] suggest that the "[[Librarian]]" was on the Earth with early modern humans 100,000 years ago. This is also made more obvious by the fact that a portal was built in East Africa to allow humans to reach [[the Ark]]. It is suggested that humans were considered to be special and we were decided to be the "inheritors of all they left behind".
