'''Guardian Custodes''',{{Ref/Reuse|wf}} commonly known simply as '''Guardians''', are powerful [[Forerunner]] constructs built to enforce the [[Mantle]] within the [[ecumene]].{{Ref/Reuse|universe}} Custodes are part of a wider category of policing constructs known as [[Peacemaker]]s. Along with the [[Preceptor]]s, the Guardians were classified as tier-two Peacemakers that were largely used to enforce order among the Forerunners' lesser subject species rather than Forerunner-inhabited systems.{{Ref/Reuse|wf}}

Manufactured by the [[Minoris Assembler Vats]], the Guardians were controlled by [[ancilla]] and operated through their connection to the [[Domain]].{{Ref/Reuse|wf}} In [[2558#October|October 2558]], [[Cortana]] took control of the Guardians to enforce the will of her [[Created]].{{Ref/Reuse|genesis}}

==Description==
===Design and operation===
{{Quote|Whoa. They built them big, didn't they? Figure that's the Guardian?|Spartan [[Edward Buck]], upon first spotting a Guardian<ref name="unconfirmed">''Halo 5: Guardians'', campaign level,
 "[[Unconfirmed]]"</ref>}}
[[File:Halo 5 - Meridian Guardian.jpg|thumb|250px|left|A Guardian preparing to leave Meridian.]]
The body of the Guardian Custode is variable and ever-changing, shaping itself to awe, inspire, and maximize effectiveness of all defensive systems. Generally, Guardians have a segmented body and elaborate, phoenix-like wings consisting of multiple segments. They possess a head that is vertically roughly elliptical, topped with a broad, vaguely conical protrusion and a roughly humanoid face similar to that of the [[Promethean]] constructs. The appearance of the Guardians unnerved many [[Forerunner]]s, though all attempts to change their look were unsuccessful.{{Ref/Reuse|wf}} The Guardians are enormous constructs, measuring just over 1,412 meters (4,635 feet) in height,{{Ref/Reuse|universe}} with a mass of two hundred million metric tons.{{Ref/Reuse|wf}}

They are capable of concealing themselves underground,<ref name="thb">''[[The Hunt Begins]]''</ref> underwater,<ref name="BOS">''Halo 5: Guardians'', campaign level, "[[Battle of Sunaion (level)|Battle of Sunaion]]"</ref> and under lava, and are also capable of traveling through [[slipstream space]].{{Ref/Reuse|Guardians}} The wings of the Guardians, known as "focus wings", contain energy condensers which draw power from the surrounding quantum vacuum. They also contain effectors which magnify the Custode's [[electromagnetic pulse]].{{Ref/Reuse|wf}} Guardian shielding is capable of withstanding the attack from a [[human]] [[UNSC frigate|frigate]]'s [[Magnetic Accelerator Cannon]], as well as numerous [[missile]]s.<ref name="F349">"[[Rossbach's World (story)|Rossbach's World]]" – ''[[Halo: Fractures]]'', p. 349</ref> Guardians had the authority to plant [[assembler vats]] on the worlds they monitored, which would eventually grow and expand to staging areas and factories for the lesser [[Sentinel]]s and [[weapon-ship]]s that served them.{{Ref/Reuse|wf}}

The constructs have no crew and instead each Guardian is controlled by an [[ancilla]] who inhabits the Custode. These ancillas have limited personality and empathy, having grown strange and aloof. Service as a Guardian and deep synchronization with the [[Domain]] reshaped the minds of the ancillas into a form that was considered best suited to serve the [[Mantle of Responsibility]] and enforce the prime directives that had first been outlined when even the Forerunners were young. Guardians were connected to the Domain's [[overwatch network]], which allowed them to reflexively counter many threats to the [[ecumene]] long before they gained the attention of [[Warrior-Servant]] commanders.{{Ref/Reuse|wf}}

Guardians were closely attuned to the ecumene's legal authorities, with the Domain ensuring that the constructs were often available to assist or monitor their activities.  Through their connection to the Domain, the Guardians recorded the feats and struggles of those under their protection into the archives of the Domain. Occasionally, Guardians would take independent action to serve a greater purpose when the Domain resonated with these events.{{Ref/Reuse|wf}}

===Armaments===
[[File:Halo 5 - Guardian on Earth.jpg|thumb|250px|A Guardian emits an attenuation pulse.]]
{{Quote|Guardian's got a hell of a singing voice.|Edward Buck, as a Guardian prepares to fire its disruption generator<ref name="evacuation">''Halo 5: Guardians'', campaign level, "[[Evacuation]]"</ref>}}
The Guardian Custode's primary weapon is a single [[disruption generator]],{{Ref/Reuse|wf}} a devastating weapon capable of destroying infrastructure caught in its blast.{{Ref/Reuse|evacuation}} The Guardian is equipped with two [[attenuation pulse emitter]]s—a multi-vector electronic warfare weapon{{Ref/Reuse|wf}} that can instantaneously neutralize local power networks through a series of debilitating pulses,{{Ref/Reuse|universe}} capable of even disabling Forerunner systems.{{Ref/Reuse|wf}} However, while their weapon is thorough, the damage it causes is not irreparable and can be repaired with time, particularly by [[Huragok]].<ref>'''[[Halo: Bad Blood]]''', ''page 106''</ref>

Guardians are also armed with six [[converging beam cannon]] emitters,{{Ref/Reuse|wf}} weapons commonly found on Forerunner [[warship]]s that emit tendrils of energy that track enemy vessels and create a path for antimatter streams to pursue.<ref>''Halo: Warfleet'', p. 80</ref> While six of these beam cannons were more than adequate to defeat the [[fleet]]s of primitive [[capital ship]]s, they were of little use when the Guardians faced Forerunner warships infested and captured by the Flood.{{Ref/Reuse|wf}} However, the energy produced when multiple Guardians concentrate the beams of these weapons together is sufficient to destroy a planet in mere seconds by cracking open its mantle and exposing its core, as seen in the annihilation of [[Doisac]].{{Ref/Game|Halo Infinite}}

The Guardians were classified as tier-two [[Peacemaker]]s, specifically purposed for security, protection, and enforcement roles within the [[Ecumene]]. However, the Guardian Custodes were first used as tenders and recorders of the [[Precursor]] legacy, though this purpose has long since faded out of living memory. While efficient protectors and enforcers, Guardians also served as immaculate record keepers,
adding the history of those under their protection to the [[Domain]]'s archives.{{Ref/Reuse|wf}}

The [[Mantle of Responsibility]], the philosophical system adhered to by the [[Forerunner]]s, was based around the belief that the most technologically developed species was charged with the stewardship of life throughout the [[Milky Way]] galaxy. As such, the Forerunners considered themselves the Mantle's upholders. However, as part of the Mantle's "code", competition and conflict was allowed as long as it did not threaten galactic biodiversity. As such entities proved to be a threat to the Forerunners' hold of the Mantle, the Guardians were designed to police the so-called "lesser" [[planet]]ary systems and enforce the Mantle's edicts on non-compliant or overly aggressive species. Guardians were utilized throughout Forerunner history to suppress rebellions or were deployed in advance as an imposing threat of force. However, they ultimately proved useless against the parasitic [[Flood]].{{Ref/Reuse|universe}}

Guardians were designed with multiple roles and functions, though their primary purpose was the monitoring and subjugation of all local power networks on subject worlds. If deemed necessary, Guardians could instantaneously neutralize these power networks through a series of debilitating pulses that incrementally increased in power.{{Ref/Reuse|universe}} A single Guardian was often enough to effectively police an entire planetary system,{{Ref/Reuse|genesis}} though the deployment of multiple Guardians at one location allowed the constructs to strategically coordinate their strike, rendering all but the most sophisticated foes completely ineffective. This method of control was largely unchallenged by other species in the galaxy.{{Ref/Reuse|universe}}

==History==
===Tools of the Mantle===
The Guardians were developed and created by the [[Forerunner]]s to enforce the [[Mantle of Responsibility]] by keeping "lesser" systems in line. The constructs were first deployed many millennia prior to the [[Forerunner-Flood war]],{{Ref/Reuse|universe}} created by the Forerunners before the time of the [[ecumene]] as tenders and recorders of the [[Precursor]]'s legacy. However, this purpose has long since passed out of living memory.{{Ref/Reuse|wf}}

Throughout Forerunner history, Guardians quelled rebellions and neutralized threats. During the Forerunners' war with the [[Flood]], Guardians were used in an attempt to combat the Flood but proved useless against the biological parasite.{{Ref/Reuse|universe}} While the Guardians' weapons proved devastating against the [[fleet]]s of "lesser" species, they were no match against the Forerunner [[warship]]s captured by the Flood.{{Ref/Reuse|wf}} As the Flood brought on the fall of the ecumene and the near-extinction of the Forerunners themselves, the Forerunners buried the remaining Guardians on isolated shelter worlds. With [[Great Purification|the firing]] of the [[Halo Array]] in [[97,445 BCE]], the Guardians were left behind when the remaining Forerunners left the galaxy; the constructs would remain dormant on their shelter worlds until called upon to serve the Mantle once again.{{Ref/Reuse|universe}}

The Guardian located on [[Sanghelios]] beneath the [[Csurdon Sea]] would later be found by the native Sangheili dive-hunters and fishing skiffs before the species even became space-faring. Nearby [[elder]]s built fortresses to observe and protect the Guardian's location, which they deemed sacred. The [[city]] of [[Sunaion]] was built over the Guardian's location in the sea as a temple to worship the construct and its creators. The [[Covenant]] later explored the Guardian for many years in an effort to learn of the construct's nature, but their attempts proved fruitless.<ref>[https://www.halowaypoint.com/en-us/universe/locations/sunaion '''Halo Waypoint''': ''Sunaion'']</ref>

At some point after the [[shield world]] of [[Sarcophagus]] was colonized, the [[Office of Naval Intelligence]] set up [[Project GOLIATH]] to study the Custodes, with [[Lucy-B091]] having some level of involvement with the project.<ref name="LoO">'''[[Halo: Legacy of Onyx]]''', ''pg. 435'' {{C|Kindle ebook edition}}</ref>

{{Main|Created conflict}}
[[File:HW2-Anders meets a Guardian.png|thumb|250px|left|A Guardian capturing Installation 09.]]
In [[2558]], [[Cortana]], who had been restored within the [[Domain]] and come to believe that the [[Created]] — human [[artificial intelligence]]s — were the true inheritors of the [[Mantle of Responsibility]], intended to use the Guardians to enforce the Mantle among all the galaxy's species. She thus began to activate the Guardians across the galaxy and summon them to the nexus of her power at [[Genesis]].<ref name="h5g">''Halo 5: Guardians''</ref> Sometime after Dr. [[Catherine Halsey]] was rescued from [[Onyx]], she discovered a signal that was being bounced around several locations across the known galaxy. One of the sources of the signal caused violent seismic activity on an unknown human colony, leaving only the symbol of the Guardians. Later, in 2558, Halsey helped the [[Office of Naval Intelligence]] access her data archive, leading to ONI hiding the presence of the Guardians from humanity.<ref>''[[Hunt the Signal]]''</ref>

In October later that year, [[Guardian emergences|Guardians emerged]] on at least twelve [[human colonies]], including [[Meridian]], [[Conrad's Point]], [[Ursa IV]], and [[Laika III]], as well as other worlds inhabited by species of the former [[Covenant]].{{Ref/Reuse|h5g}} These colonies suffered greatly from the devastation caused by the constructs' activation.<ref name="Osiris">'''Halo 5: Guardians''', campaign level, ''[[Osiris]]''</ref> When [[Blue Team]] boarded a Guardian on Meridian, the UNSC held Blue Team's leader, [[John-117]], responsible for the attacks. [[Fireteam Osiris]], led by [[Jameson Locke]], was assigned to hunt him down.{{Ref/Reuse|thb}} Later, Fireteam Osiris was tasked with retrieving a [[Constructor]] in a Forerunner structure on [[Sanghelios]] in order to activate a Guardian that had been buried under the nearby [[Csurdon Sea]].<ref name="EL">'''Halo 5: Guardians''', campaign level, ''[[Enemy Lines]]''</ref> Soon, all of the Guardians that had been awoken would soon be called to Genesis, and then be dispersed throughout human space, to serve the reclaimed [[Mantle of Responsibility]] once again. Guardians subsequently participated in the [[Subjugation of Earth]]{{Ref/Reuse|Guardians}} and one was sent back to Sanghelios when the population refused to surrender as per Cortana's demands. The Guardian's EMP blacked out the entire planet and the next morning, [[Arbiter]] [[Thel 'Vadam]] received word of the Guardian deploying Prometheans to pacify entire cities that actively resisted the Guardian.<ref name="BB">'''[[Halo: Bad Blood]]''', ''Chapter 1''</ref>

During the [[Battle of Cassidy III]], a Guardian was summoned to the planet by the AI [[Leonidas]]. The Guardian began destroying [[Hole in the Wall]] while [[Quick to Adjust]] repaired the EMP damage to the colony's escape craft, allowing them to escape. Through Leonidas, the mayor agreed to surrender and accept the Created's subjugation, though Leonidas refused to let [[Alpha-Nine]] leave in their [[Condor]]. After [[Kojo Agu]] destroyed the tablet holding Leonidas, the Guardian attacked the retreating ship and managed to knock out its power with the Guardian's attenuation pulse weapon. However, in doing so, the Guardian drained a tremendous amount of its own energy, giving Quick to Adjust the time it needed to repair the Condor so they could escape.<ref>'''[[Halo: Bad Blood]]''', ''Chapters 15-20''</ref>

A Guardian activated on the [[shield world]] of [[Sarcophagus]] during the [[Second Onyx conflict]]. The shield world's inhabitants managed to destroy the Guardian with the help of [[Prone to Drift]] and returned Sarcophagus to its [[slipspace bubble]] to protect themselves from further incursions by the Created.<ref>'''[[Halo: Legacy of Onyx]]'''</ref>

In early April of 2559, a Guardian intercepted and captured [[Installation 09]] en route to the [[Soell system]] from [[Installation 00]]. On the surface of the Halo the Guardian confronted [[Ellen Anders|Professor Ellen Anders]], who had gained control of the ring during the {{UNSCShip|Spirit of Fire}} crew's [[Second Ark Conflict|war against the Banished]] on the Ark.<ref>''Halo Wars 2'', campaign level, "[[Last Stand (Halo Wars 2 level)|Last Stand]]"</ref>

A Guardian was sent to [[Reach]] in Early October 2559, to investigate a slipspace anomaly following the opening of the [[Menachite portal complex|Ark portal on Reach]] by the [[Keepers of the One Freedom]] and the Banished.<ref>''[[Halo: Shadows of Reach]]'', Epilogue</ref>

When [[Atriox]] refused to surrender on behalf of the [[Jiralhanae]], Cortana sent at least eight Guardians to [[Doisac]] where they completely destroyed the planet in an act of genocide.{{Ref/Reuse|Hi}}

==Production notes==
[[File:H3 Guardian Concept 4.jpg|thumb|125px|right|Near-final concept art for the [[Guardian Sentinel|Guardian]] in ''Halo 3''.]]
The idea of large Forerunner constructs known as "Guardians" dates back to the development of ''[[Halo 2]]''. This concept was further explored for ''[[Halo 3]]'', with many pieces of concept art created for their design. These [[Guardian Sentinel|Guardian]]s were to feature as enemies in the eponymous level ''[[Guardian Forest]]''.{{Ref/Site|Id=GDC|D=01|M=6|Y=2020|URL=https://www.gdcvault.com/browse/gdc-09/play/1284|Site=GDC Vault|Page=Building Your Airplane While Flying: Production at Bungie}}{{Ref/Site|Id=Powerpoint|D=01|M=6|Y=2020|URL=http://downloads.bungie.net/presentations/gdc_bungieproduction_march2009.pptx|Site=Bungie.net|Page=Building Your Airplane While Flying: Production at Bungie|Detail=Original presentation download}} Unfortunately, the level and the Guardian enemy had to be cut, with the environment being repurposed as the ''[[Guardian (map)|Guardian]]'' multiplayer map and the Guardian enemy model itself used on ''[[Epitaph]]'' in holographic form. The Guardian was intended to be similar in size to the similarly-cut [[Strato-Sentinel]]s.{{Ref/Site|Id=Vic1|D=01|M=6|Y=2020|URL=https://twitter.com/vicdeleon/status/1304910772313575424|Site=Twitter|Page=Vic DeLeon|Quote=Fwiw this is almost exactly what the Guardians looked like back when they were first imagined on Halo 2, only they were much larger, almost like the Strato-Sentinel.}} While not seen in the final game, the Guardian design was later used in ''[[Origins]]'' for two Forerunner constructs seen escorting a [[Keyship]] to the [[Portal at Voi]].{{Ref/Film|Id=OriginsI|HLeg|Detail=[[Origins]]}} Another hologram of this design of Guardian appears in ''[[Halo Infinite]]''.{{Ref/Site|Id=InsideApril|D=30|M=4|Y=2021|URL=https://www.halowaypoint.com/en-us/news/inside-infinite-april-2021|Site=Halo Waypoint|Page=Inside Infinite - April 2021}}

The Guardians' first major appearance in the ''Halo'' series was as a major plot element (and origin of the name for) ''[[Halo 5: Guardians]]''. In ''Halo 5'', these Guardian Custodes were vastly different in design, resembling birds moreso than the monolithic Sentinels. Early in the development of ''Halo 5: Guardians'', the Guardians were known internally as "Titans", and went through heavy design iteration.{{Ref/Site|D=01|M=6|Y=2020|URL=https://www.artstation.com/artwork/qAkxwR|Site=ArtStation|Page=TITAN}}{{Ref/Site|D=01|M=6|Y=2020|URL=http://www.axisanimation.com/features/halo-xbox-one/|Site=Axis Animation|Page=Halo Xbox One}} By mid-[[2013]], the bird design had become semi-final, and can be seen in the ''[[Halo Xbox One announcement trailer]]'' and ''[[Halo 2: Anniversary]]'' bookend cutscenes, though the final design in ''Halo 5: Guardians'' was changed radically. There was considerable speculation as to the nature of the constructs prior to the confirmation of them as the titular Guardians in ''Game Informer''{{'}}s June 2015 issue. When asked about the construct seen in the ''Halo 5: Guardians'' key art on Twitter, the game's Creative Director [[Josh Holmes]] alluded to the name by replying that ''"The answer is in plain sight."''<ref name="Josh Holmes">[https://twitter.com/JoshingtonState/status/592477020073828352 '''Twitter''': ''Josh Holmes'']</ref>
