Guardian Custode
Overview
Role:	Enforcement of the Mantle and the policing of star systems
Height:	1,412.75 meters (4,635 feet)

031 Exuberant Witness: "A single Guardian can effectively police a solar system. This show of force is unsettling."

Olympia Vale: "I'm sorry, 'police'? 'Show of force'?!"

031 Exuberant Witness: "Indeed. Guardians are how the Forerunners enforced peace on the lower systems."

— 031 Exuberant Witness and Olympia Vale, after Cortana called several Guardians to Genesis

Guardian Custodes, commonly known simply as Guardians, are enormous Forerunner constructs built to enforce the Mantle within the Forerunners' ecumene. Custodes are part of a wider category of policing constructs known as Peacemakers. Unlike the most powerful types of Peacemakers, the Guardians, along with the Preceptors, were largely used to enforce order among the Forerunners' lesser subject species rather than Forerunner-inhabited systems.

Description

"Whoa. They built them big, didn't they? Figure that's the Guardian?"

— Spartan Edward Buck, upon first spotting a Guardian

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 Guardians are enormous constructs, measuring just over 1,412 meters (4,635 feet) in height.

They are capable of concealing themselves underground, underwater, and under lava, and can produce powerful shockwaves capable of demolishing buildings and destroying aircraft. They are also capable of travel through Slipspace and produce powerful electromagnetic pulses. For defense Guardians are capable of generating energy blasts from their wingtips. Guardian shielding is capable of withstanding the attack from a UNSC frigate's Magnetic Accelerator Cannon.

Roles

A Guardian emitting an electromagnetic pulse over Earth.

The Mantle of Responsibility, the philosophical system adhered to by the Forerunner ecumene, 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" planetary 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.

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. A single Guardian was often enough to effectively police an entire planetary system, 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.

History

Tools of the Forerunners

The Guardians were developed and created by the Forerunners to enforce the Mantle by keeping "lesser" systems in line. The constructs were first created thousands of years prior to the Forerunner-Flood war. 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. As the Flood brought on the fall of the Forerunner ecumene and the near-extinction of the Forerunners themselves, the Forerunners buried the remaining Guardians on isolated shelter worlds. With 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.

Millennia later, many of these worlds would be settled by other species, including humanity and the Sangheili. 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 elders built fortresses to observe and protect the Guardian's location, which they deemed sacred. The city of Sunaion was later 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.

"She calls the Guardians to serve her!"

— The Warden Eternal, referring to Cortana

A Guardian preparing to leave Meridian.

In 2558, Cortana, who had been restored within the Domain and come to believe that the Created — human artificial intelligences — 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. 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.

In October later that year, 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. These colonies suffered greatly from the devastation caused by the constructs' activation. 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. 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. 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.

In early April of 2559, a Guardian intercepted and captured Installation 04C en route to the Soell system from Installation 00. On the surface of the Halo the Guardian confronted Professor Ellen Anders, who had gained control of the ring during the UNSC Spirit of Fire crew's war against the Banished on the Ark.

• A Forerunner construct called "the Guardian" was originally set to appear as an enemy in a Halo 3 campaign level that later became a multiplayer level Guardian. It was stated that the player would have been able to rip out the Guardian's eye beam and use it as a weapon in the campaign level. According to Art of Halo 3, "The Guardian evokes memories of Compilers (from one of Bungie's previous games, Marathon) and the robes of a High Court Judge - which is fitting because, as anyone who has encountered them can tell you, their judgments are swift and final, and their logic utterly alien." While they were not seen in the final game, their design was later used in Origins for two Forerunner constructs seen escorting a Keyship to the Portal at Voi.
• An early version of the Halo 5: Guardians incarnation of the Guardians was first seen in the Halo Xbox One announcement trailer and later in the bookend cinematics of Halo 2: Anniversary, with the final design revealed in promotional artwork. 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."
