{{Quote|The scale and brilliance of the Didact's strategic plan now appears more like the tomb of all hope—certainly of all my hopes.

'''Requiem''', formally designated by its [[Forerunner]] creators as '''Shield World 0001''',{{Ref/Reuse|DK H4TEVG}} was a Forerunner [[shield world]] located in the [[Epoloch system]].{{Ref/Reuse|DK H4TEVG}} It once served as the central base of operations for the [[Promethean]]s, an elite class of [[Warrior-Servant]]s, for thousands of years until the end of the [[Forerunner-Flood war]].

==History==
===Ancient history===
[[File:HTMCC-H4 Terminals RequiemWarRoom.png|thumb|left|250px|The [[Didact]] and the [[Librarian]] in Requiem's war room.]]
Built as the template for the [[Ur-Didact|Didact]]'s [[shield world]] [[Star-hopping|defensive strategy]], Requiem was constructed long before the [[human-Forerunner wars]] to serve as a fortress world for the [[Warrior-Servant]]s' Promethean class. As with the shield worlds which would follow, Requiem's true capabilities were kept as secret as possible from the other [[rate]]s; although its components were constructed by the [[Builder]]s, the process was compartmentalized in a way that only the Prometheans would be fully informed of its ultimate configuration.{{Ref/Novel|Sil|Page=278-279}}

Requiem was a central hub for all Forerunner forces and war efforts for thousands of years, from the conflict with [[prehistoric human civilization|ancient humanity]] to the end of the [[Forerunner-Flood war]].{{Ref/Reuse|h4guide}} Upon his recovery from the clutches of the [[Gravemind]] near the end of the conflict with the Flood, the now mentally unstable [[Ur-Didact]] returned and reassumed control of Requiem. In his vision, Requiem was to serve as a core of a new era of prosperity and power to the Forerunners through the defeat of the Flood and the subjugation of all their enemies. To this end, the Didact used the [[Composer]] to convert his loyal Warrior-Servants into powerful robotic [[Promethean Knight|Knights]]. Despite his grand plans, relatively few of his Warriors joined him: in addition to the Didact's flagship, ''[[Mantle's Approach]]'', only one [[Fortress-class vessel]], several [[Forerunner dreadnought|dreadnoughts]] and scrapped Builder vessels were present at Requiem during the endgame of the war.{{Ref/Novel|Sil|Page=281}}

After the Ur-Didact used the Composer to enslave [[Omega Halo]]'s human population to use them to create more of his Knight constructs, the [[Librarian]] imprisoned the Didact in a [[Cryptum]] in the core of the shield world to stop him.{{Ref/Game|Id=h4terminals|H4|Detail=''[[Terminal (Halo 4)|Terminals]]''}} The Librarian [[Mind transfer|uploaded]] a [[Librarian's Rest|personality impression]] of herself within Requiem's systems,{{Ref/Level|Id=Reclaimer|H4|[[Reclaimer (level)|Reclaimer]]}} placing the [[Janus Key]] in the possession of this imprint.<ref name="Key">''Spartan Ops:'' ''[[S1/Key|S1E9 Key]]''</ref> The Librarian then departed Requiem and sealed the shield world off for the next 100,000 years.

===Rediscovery===
{{Main|Battle of Requiem|Requiem Campaign}}
[[File:H4 SongOfRequiem.png|thumb|left|250px|Jul 'Mdama's ''[[Song of Retribution]]'' first arriving at Requiem.]]
In [[2554]], [[Jul 'Mdama]] and his [[Jul 'Mdama's Covenant|Covenant]] discovered Requiem, using coordinates provided by Forerunner symbols. Over the next three years, his Covenant tried to enter the planet, without success.

[[File:Planet 1.jpg|thumb|250px|The {{UNSCShip|Forward Unto Dawn}} entering Requiem via an access portal.]]
On [[2557#July|July 21, 2557]], the severed aft section of the {{Class|Charon|light frigate}} {{UNSCShip|Forward Unto Dawn}}, containing [[John-117]] and [[Cortana]], drifted near Requiem and were forcibly pulled inside an automated entrance portal on its surface, along with a number of ships from a [[Covenant remnants|Covenant remnant]] [[Covenant Fleet|fleet]] and later, the {{Class|Infinity|supercarrier}} {{UNSCShip|Infinity}}.<ref>''[[Halo 4 E3 2012 Stage Demo]]''</ref> Inside, they encountered hostile [[Promethean]] forces that occupied the structure, and unwittingly released the Didact.<ref name="waypoint">[http://halo.xbox.com/en-us/games/overview/halo4 ''Halo Waypoint'': ''Halo 4'']</ref> The humans battled their way through the world, destroying its [[Gravity well|gravity well generator]] so the ''Infinity'' could escape. The ''Infinity'' escaped from the shield world, and despite the best efforts of the [[John-117|Master Chief]] and [[Cortana]], the Didact escaped as well to go after the [[Composer]], chased by the two in a [[Lich]]. Six months later, the ''Infinity'' returned to Requiem in order to establish research facilities to study the installation, facing both the local Prometheans and Jul's Covenant forces which still occupied the structure.{{Ref/Reuse|departure}}

===Destruction===

[[File:Requiem destruction.png|thumb|250px|UNSC ''Infinity'' fleeing the flare emitted immediately after Requiem's collision with Epoloch.]]
In February [[2558]] Jul 'Mdama, believing to have obtained the [[Janus Key|artifact]] they sought, implemented a local [[Flood]] [[containment protocol]],<ref name="CatalogContainment">[https://forums.halowaypoint.com/yaf_postsm2994218_Catalog-Interaction.aspx#post2994218 ''Halo Waypoint'': ''Catalog Interaction'' (post 2994218)]</ref> placing Requiem on a collision course with its parent star, Epoloch, in effect setting Requiem to [[self-destruct]]. With the ''Infinity'' anchored to the planet via a slipspace conduit generated by a [[Requiem slipspace artifacts|Forerunner artifact]] on board, Fireteams [[Fireteam Majestic|Majestic]] and [[Fireteam Crimson|Crimson]] were sent to deactivate two artifacts on Requiem that kept the ship anchored, while [[Henry Glassman]] deactivated the third one aboard the ''Infinity''. After many complications, both fireteams reached their objective and the ''Infinity'' was able to flee the planet,{{Ref/Reuse|Exodus}} seconds before Requiem was consumed by the sun, which went [[supernova]] immediately afterward due to a total failure of local plasma shell maintenance systems as well as Requiem's containment measures.{{Ref/Reuse|CatalogContainment}}

==Description==
===Structure===
[[File:Halo4-Cortana-RequiemCore.jpg|thumb|300px|[[Cortana]] observing the core of Requiem.]]
The most resilient shield installation built by the Forerunners, Requiem consisted of multiple concentric planetary shells enclosed within one another, sealed inside an enormous outer shell.{{Ref/Reuse|h4guide}} The outermost surface was an armored covering enveloping the second shell, which was oriented like that of a planet and housed the world's primary terrestrial environment. [[Core of Requiem|Requiem's core]] was located below this planetary surface, and had a surface reverse to that of the terrestrial exterior, similar to a miniaturized [[Dyson sphere|Dyson shell]].

Requiem's outer surface was a thick metallic shell lacking a terraformed surface and covered in patterns and layers of machinery and overlapping armor plating hundreds of kilometers thick; the first 50 kilometers were to feature weapon emplacements by the thousands, but these plans were never realized due to the Didact's exile.{{Ref/Novel|Sil|Page=282}} The surface was also covered in a number of lights; some of these formations took on geometric patterns, such as circular orientations or arrays of lines. Amongst its complement of luminous formations were two enormous symbols; the Eld, (which represents the [[Mantle]]), as well as the [[Reclaimer]] glyph. Unlike some shield worlds constructed later on, Requiem did evidently not possess shielding against the effects of the Halo Array; the Didact was only protected by the [[slipspace bubble]] generated by his [[Cryptum]].<ref name="Bulletin924">[https://blogs.halowaypoint.com/en-us/blogs/headlines/posts/the-halo-bulletin-9-24-14 ''Halo Waypoint'' - ''The Halo Bulletin: 9.24.14'']</ref>

[[File:H4-Req Map.png|thumb|300px|A holographic representation of Requiem.]]
The interior of the facility was unique relative to the other known shield worlds; rather than housing an artificial star at its center, surrounded by a habitable inner surface, the exterior shell housed additional layered shells, the outermost of which had an environment resembling a terrestrial planet. Another important feature was that immediately above the cloud layer of the protected second layer, the interior surface of the protective shell was visible. This was demonstrated by the sky being dominated by the machinery above it, with large, vertical structures reaching down to the surface below. Numerous small artificial stars provided illumination for Requiem's interior.{{Ref/Novel|Id=sil283|Sil|Page=283}}

The innermost miniature Dyson shell housed the core of Requiem, which was where the Didact's Cryptum was situated. The platform which housed the Cryptum was suspended in the very center of the sphere and was protected by a shield emitted by two adjacent pylons located on opposing sides on the surface of the inner sphere. Two enormous energy conduits perpendicular to one another ran between the pylons across the entire inner surface. The surface in the inner shell mostly consisted of rocky desert landscape dense with prominent arrangements of light indicating the presence of large-scale structures.

===Features===
[[File:Requiem.png|thumb|left|300px|A general view of Requiem.]]
A readily seen feature of this construct is that it harbored a number of large circular entrance portals, with iris-type opening mechanisms. When opened, a vibrant, blue-white light could be seen emanating from the interior. These portals featured the ability to generate artificial [[Gravity well (physics)|gravity well]], drawing in objects in the immediate vicinity if the presence of [[Reclaimer]] is detected. These gravity wells were powered by generator complexes situated somewhere on the inner planetary shell.{{Ref/Reuse|Reclaimer}}

The next known aspect of this facility is that it possessed fully active and functioning technology, unlike other Forerunner sites, which have largely been abandoned and dormant,<ref>[http://www.youtube.com/watch?v=JD429ZWcQ_w ''YouTube'': ''Halo Fest: Halo 4 Panel'']</ref> with the exception of [[Trevelyan|Shield World 006]]. Examples of such active technology included enormous spires suspended in the air without visible support and structures capable of shifting and reconfiguring themselves, extensive use of sophisticated [[hard light]] construction to create structural elements, or the Prometheans' various weapon and equipment caches found across the shield world.

Designed to wage continuous war for eons if necessary, Requiem was completely self-sustaining. It was orbited by seven captured planetoids, covered in ice, which could be strip-mined for resources, allowing its occupants to survive and carry out their campaigns potentially for millions of years. Like most Forerunner technology, Requiem drew its power from [[vacuum energy]], with pylons across the structure tapping into numerous nascent alternate universes and draining them of energy.{{Ref/Reuse|sil278}} Large regions of the terrestrial interior were kept dormant, with the landscape covered in mineral-rich ice, to be melted down to create more refuges for Forerunners and other species in the event of an extended campaign.{{Ref/Reuse|sil283}}

For travel between the layers and various locations, Requiem used [[Teleportation grid#Requiem|teleportation portals]] that could transport anyone who used them to different locations on the shield world. Due to her experience and expertise with Forerunner technology, the [[Artificial intelligence|AI]] [[Cortana]] was capable of controlling these portals. The Prometheans that occupied Requiem were capable of generating portals and translocating across the shield world.

==Production notes==
{{Quote|Requiem needed to be impactful; it needed to take the player back to the epic mystery and nostalgia of exploring the first ''Halo'' video game a decade ago. Making weird and alien spaces is not terribly challenging. Keeping them from falling into abstraction or failing to be believable is. Keeping the player invested and finding those keys to keeping him or her immersed was our goal.|[[Kenneth Scott]]{{Ref/Art|AoH4|Page=22}}}}

Early concept art for ''Halo 4'' display a decidedly different concept for Requiem's entry portal than the final incarnation. Whereas in the game the entrance opens directly to the inner planetary shell underneath, several works of concept art depict the interior of the opening as a cavernous, structured space which appears to lack gravity.

Prior to ''[[Halo 4]]'', Requiem was known among fans as the ''Legendary Planet'', referring to the planet's first appearance in ''Halo 3's'' Legendary difficulty-exclusive ending. Requiem also appears in a small image in the ''[[Halo Encyclopedia (2009 edition)]]'', where it is shown to have a reddish-orange color on a small illuminated section.{{Ref/Book|H4EVG|Page=279}} The planet appears again in the [[Awakening|''Halo 4'' announcement trailer]], where the aft half of the ''Forward Unto Dawn'' is seen being pulled into a massive, iris-like opening on its surface.<ref>[[Awakening|''Halo 4'' Announcement Trailer]]</ref><ref>[http://www.gametrailers.com/video/e3-2011-halo-4/714846 ''GameTrailers'': ''E3 2011: Halo Returns Interview (Stream) HD'']</ref> The planet was finally identified as "Requiem" in the May 2012 issue of the ''GameInformer'' magazine.<ref name="gameinformer">''Game Informer'' ''(May 2012)'', ''page 44-45''</ref>

According to [[Brian Reed]], the lead writer of ''Spartan Ops'', Requiem is the largest Forerunner construct in history, though this is far from accurate:<ref>[http://youtu.be/A3KLtf8DzCU ''Youtube'' ''Halo 4: A Hero Awakens Behind the Scenes'']</ref> With a diameter of 10,787 kilometers,{{Ref/Reuse|DK H4TEVG}} Requiem is dwarfed by several Forerunner constructs, such as the [[Capital]] (~ 100,000&nbsp;km), [[Installation 00]] (127,530&nbsp;km), and especially [[Trevelyan|Shield World 006]] (~ 300,000,000&nbsp;km).

Requiem being pulled into its star was originally suggested as a joke by [[Frank O'Connor]] during a brainstorming session on the ending of the first season of ''[[Spartan Ops]]''.<ref name="Bulletin">[http://blogs.halowaypoint.com/Headlines/post/2013/02/27/The-Halo-Bulletin-22713.aspx ''Waypoint'': ''The Halo Bulletin: 02.27.13'']</ref>

==Trivia==
{{Linkbox|gallery=yes|gallerypage=Images of Requiem}}
*A [[Wikipedia:requiem|requiem]] is a Catholic mass dedicated to the souls of the deceased, often celebrated at funerals.
*"Requiem" comes from the Latin word requiem, which means rest (A reference to the [[Ur-Didact]]).
*Many [[Huragok]] know that Requiem is home to the Didact. However, they do not know its location as a security measure. {{Ref/Novel|TTW|Page=115}}
*An image of Requiem is used to advertise an in-universe film titled ''Dark Planetoid Rising'' on the {{UNSCShip|Pillar of Autumn}}'s [[bulletin board]] in ''[[Halo: Combat Evolved Anniversary]]''.
*Requiem is designated as "43121124" by the holographic terminal displaying the ''Dawn''{{'}}s predicted drift course.{{Ref/Level|Id=Dawn|H4|[[Dawn]]}}
*''[[Halo 4: The Essential Visual Guide]]'' and the shield world's in-game appearance in ''Halo 4'' seem to indicate that Requiem has only one entry portal, referred to as the "maw corridor" in the visual guide.{{Ref/Reuse|DK H4TEVG}} Despite this, the ''Halo 4'' terminals and ''Halo: Silentium'' portray Requiem as having a number of access corridors.{{Ref/Novel|Id=s281|Sil|Page=281}} It is possible that the other portals were sealed off with Requiem when the Didact was placed into stasis, likely as a safeguard against the Halos' activation.
