This article is about the Forerunner term. For articles of the same name, see Reclaimer (disambiguation).
"Reclaimer" is a Forerunner term used to refer to a species (or a member of said species) chosen to be the inheritors of the Mantle, the stewardship over all life originally held by the Precursors. Following the activation of the Halo Array and the ensuing Reintroduction, this refers to humans, whom the Forerunners (more pointedly those allied with the Librarian) regarded as their rightful successors. In particular the term is applied to humans who carry the requisite Lifeworker-created geasa that allow them to activate Forerunner technology; indeed, a great deal of the Forerunners' abandoned technology may be activated only when used by a Reclaimer. For most of their history, however, the Forerunners considered themselves the rightful inheritors of the Mantle from the Precursors, who had originally intended to pass the Mantle down to humanity.
Generally speaking, the term "Reclaimer" refers to humans (as a species or as individuals) retaking stewardship of the Mantle. However, technically the term denotes humans who are capable of activating Forerunner technology. This is due to the presence of geas implanted by the Librarian, which give at least some humans an instinctive familiarity (often a feeling of déjà vu) when encountering Forerunner technology. For example, Spartan John-117 simply "knew" how to activate a holographic control panel on Halo Installation 04, despite it being the first piece of Forerunner technology he had ever encountered. This innate knowledge extends to Covenant technology as well, as Covenant technology is crudely reverse-engineered from Forerunner designs. In the same vein, Forerunner technology responds to human presence much as it would have done in the presence of its creators, though it will not do so for other species. Though it is unclear how commonly the geas may be found among humans, it is known that at least some are incapable of properly interfacing with Forerunner technology.
Along with implanting the geas necessary to utilize Forerunner relics, the Librarian planted "seeds" that led to some of humanity's most important technological achievements. Specifically, this genesong led to the creation of the SPARTAN programs and their MJOLNIR Powered Assault Armor, as well as Smart AI. These developments enabled humanity - primarily through the efforts of John-117 and Cortana - to defeat the Ur-Didact during his renewed campaign to compose humanity into Promethean Knights. Despite this tragedy, the Librarian originally hoped that the Didact would emerge from stasis after millennia of meditation to guide humanity; he was to give them the Janus Key, thereby providing the location of all Forerunner technology in the galaxy and securing the Reclaimers' ascendancy.
The status of Reclaimer was conferred upon humanity as an emergency directive on the authority of the remains of the New Council (namely the Librarian and the IsoDidact) during the events surrounding the firing of the Halo Array. This overrode the Builder-controlled Old Council's previous ruling from ten thousand years earlier which involved humanity's biological and technological regression as punishment for their part in the human-Forerunner wars. However, following the enactment of this punitive measure, the Librarian had been secretly modifying humanity's geas for thousands of years to prepare them to take on the role of Reclaimers — against the direct orders of the Council.
Strangely, 343 Guilty Spark, the monitor of Halo Installation 04, once insisted to John-117, "You are Forerunner." This is presumably metaphorical, as Mendicant Bias likewise claimed the Reclaimers as its makers, despite humanity being genetically and culturally distinct from the Forerunners. Alternately, this may be due to the onset of rampancy; Guilty Spark had previously treated the Master Chief as if the latter were the IsoDidact, responding to a question the IsoDidact had asked 100,000 years prior.
Failures to recognize Reclaimer status
As the UNSC Spirit of Fire was pulled inside of the Etran Harborage on February 23, 2531, the ship and her crew were scanned by the installation's decontamination network. In addition to detecting a high-order Flood infestation, the ancilla in charge of the network's cleansing rings failed to recognize the crew as Reclaimers. As the Spirit's crew and complement were regarded as an "unknown alien intrusion", they were forced to engage a bevy of Sentinels in addition to fighting the Flood on the surface of the ship.
During the Onyx Conflict in October-November 2552, the SPARTAN-III Ash-G099 failed to provide the appropriate counter-response to a Sentinel that was attempting to determine whether he was a Flood vector. This, combined with the Spartans of Gamma Company being inundated with neurology-altering mutagens, caused the Sentinel to catalog Ash as a "non-Reclaimer", as well as a member of a "aboriginal subspecies" of humanity.
Humans identified as Reclaimers
Given that all known bestowals of the "Reclaimer" title have occurred during military engagements, all individuals identified as such have been either military personnel or civilian advisers.
As understood by the Covenant
The Reclaimer glyph was one of the holiest icons in the Covenant religion, as well as the source of one of its greatest flaws. For millennia, the Covenant's leadership misinterpreted the "Reclaimer" glyph (which they read upside down) as "Reclamation". The Prophets misconstrued this as the Covenant's divine mandate to procure "holy" Forerunner technology from areas of space known as reliquaries; the Ages of Reclamation were designated as periods of significant Forerunner discoveries. While incorrectly understood by the Covenant as their quest for Forerunner relics, the Reclamation is an actual concept pertaining to the Reclaimers' process of reattaining the Mantle. Like the Forerunners, the Covenant (if only the Prophets) considered themselves the inheritors of the Mantle. However, because the Covenant's member species are not recognized as Reclaimers (being referred to as "intruders" and "meddlers" by 343 Guilty Spark), they require human captives to activate certain Forerunner technology, most notably the Halo rings, the Ark, and shield worlds. One notable exception is Jul 'Mdama, who gained the allegiance of the Promethean Knights on the shield world Requiem following the Didact's apparent demise; he was able able to set Requiem on a collision course with its star, though it seems he was given the Didact's override to accomplish this.
For many Ages, the Covenant used Luminaries (crude AIs based on Forerunner ancillas) to pinpoint concentrations of Forerunner artifacts. At the turn of 2524 - 2525, the Luminary aboard the vessel Minor Transgression led the ship's crew to the human colony world of Harvest. Ultimately, communications between the planet's government and the Covenant broke down, leading to the first major conflict between the two civilizations and the planet's eventual glassing. A trio of mid-level San'Shyuum ministers consulted the "Oracle" aboard the Forerunner Dreadnought on High Charity about the "Reclamation" glyphs encountered in such large numbers on Harvest; these San'Shyuum hoped to use the clout gained from this discovery to oust the current triumvirate of Hierarchs. The Oracle, which was actually the AI Mendicant Bias, informed the party that the luminations found on Harvest were actually the world's human population, and that the symbol the Covenant had long held to mean "Reclamation" actually meant "Reclaimer"; following this revelation, Mendicant Bias attempted to leave High Charity and make contact with its so-called "makers", though the ship was disabled and the AI quarantined before this could happen.
The schemers interpreted the Oracle's words to mean that humans were actually the living remnants of Forerunner civilization; this would directly contradict the Covenant's dogma regarding the Great Journey, which held that the Forerunners used an artifact known as Halo to transcend to godhood. Accordingly, the newly ordained Prophet of Truth declared a war of extermination upon humanity, secretly hoping that genocide would prevent humanity's relation to the Forerunners from coming to light. In the wake of commencing the Ninth Age of Reclamation, Truth also revealed that the Reclaimer glyph could help the Covenant scour the galaxy for any other human colonies.
