'''Keyship''' is a classification of [[Slipstream space|superluminal]] [[Forerunner]] [[Forerunner starship|vessel]] in use both during and after the [[Forerunner-Flood war]]. Keyships are capable of activating strategically-placed [[slipspace portal]]s hidden across the [[Milky Way]], including those leading to and from [[Installation 00]].{{Ref/Book|Id=WF|HWF|Page=84-85}}{{Ref/Book|Id=Enc22P384&385|Enc22|Page=384-385}} Though many keyships once existed, the majority of the vessels were destroyed by the [[Librarian]] to prevent the Flood from reaching the Ark.{{Ref/Game|Id=Terminal4|H3|Terminal (Halo 3)|Terminal 4}} The most notable of the surviving vessels is {{Class|Supernal Spiral|keyship}} known as ''[[Anodyne Spirit]]''. Once the centerpiece of the [[Covenant]]'s holy city of [[High Charity]], ''Anodyne Spirit'' now rests on Installation 00 in the midst of [[Second Ark Conflict|a new conflict]].{{Ref/Reuse|Enc22P384&385}}

==Overview==
===Design details===
Despite multiple classes of keyship existing, their sole mission of preservation resulted in little change between them. Keyships have a fixed tetrahedral shape consisting of three relatively narrow struts extending from its massive, elongated prow. While each keyship incorporates a full suite of defensive countermeasures and powerful [[Energy shielding|shielding]], their primary defense lies in its combination of speed and agility.{{Ref/Reuse|Enc22P384&385}}

===Purpose===
Utilized by members of the [[Lifeworker]] [[rate]], keyships were built exclusively to facilitate the [[Librarian]]'s [[Conservation Measure]] and their crews were renowned for their devotion to the tenets of the [[Mantle of Responsibility]]. Their role in this endeavor cannot be overstated; keyships were used to transport specimens of sentient species from worlds across the [[Milky Way]] to [[Installation 00]] where they would be safe from the effects of the [[Halo Array]]. Then, once the array was [[Great Purification|activated]], the keyships would return to the same planets they had visited previously to reseed them with life.{{Ref/Reuse|Enc22P384&385}}{{Ref/Site|URL=https://www.halowaypoint.com/news/the-new-halo-encyclopedia-is-out-today|Site=Halo Waypoint|Page=The New Halo Encyclopedia is Out Today|D=11|M=03|Y=2023}}

[[File:HM SiegeAtVoi.jpg|250px|thumb|The keyship ''[[Anodyne Spirit]]'' is used to open [[Excession|a slipspace portal]] on [[Earth]].]]
In order to facilitate the rapid movement of the specimens, each keyship contains permission codes and interlocks necessary to control [[Slipspace portal|portal complexes]] buried on strategic [[planet|world]]s across the galaxy, including those that connect to extragalactic locations such as Installation 00.{{Ref/Reuse|Enc22P384&385}}

Upon reaching a planet targeted for indexing, a keyship's [[Forerunner]] crew would initiate a detailed cataloguing and sampling process to identify exemplary specimens. Then, these specimens would be retrieved and placed in stasis within the keyship's [[cylix]] repositories. Once its tasks were complete, the keyship would return to Installation 00 and wait until the activation of the Halo Array. Following the immensely destructive pulse, the keyship would visit the very same worlds it did previously, generally without the presence of a Forerunner crew. Under the protection and supervision of a single high-order [[ancilla]] and hosts of [[sentinel]]s, these worlds were reseeded with life. If needed, the keyship could also use onboard automated systems to clone and biofabricate healthy replacements to supplement its catalogued populations.{{Ref/Reuse|Enc22P384&385}}

==History==
===Forerunner-Flood war===
During the [[Forerunner-Flood war]], the Forerunners used its fleet of keyships to index countless species. A number of keyships were given to the Librarian, and combined with her ability to build [[slipspace portal]]s to Installation 00, the Librarian was able to transport herself back to Installation 00 if the situation required. The Librarian, however, would ultimately destroy her personal keyships to prevent them from falling into the hands of the Flood. Near the end of the war, keyships were part of an unknown strategy to hold off the Flood for nearly 79 years, although this advantage would be foiled by the massive computing power of the Flood.{{Ref/Game|H3|Terminal (Halo 3)|Terminal 5}}

As part of the Conservation Measure, Forerunner Lifeworkers gathered DNA and living specimens of the sentient species located throughout the galaxy, protecting them from the devastation of Halo by transporting them to Installation 00 within these keyships. After the ringworlds fired out their pulses, the keyships were sent to the planets from which the sentient species originated, releasing a population of the species on their planet of origin.{{Ref/Film|HLeg|Episode=Origins}} After reseeding the galaxy with life anew, the keyships returned to Installation 00.{{Ref/Reuse|Enc22P384&385}}

===Legacy===
Centuries after the keyship ''[[Anodyne Spirit]]'' returned to Installation 00, a fragment of the imprisoned [[Mendicant Bias]] managed to infiltrate the vessel and attempt to use it to return to [[Earth]] where it planned to atone for its sins by assisting [[human|humanity]], the [[Reclaimer]]s. However, the [[Contender-class artificial intelligence|Contender-class ancilla]] failed in its task, ultimately crashing on the San'Shyuum homeworld of [[Janjur Qom]].{{Ref/Reuse|Enc22P384&385}} In the following millennia, the San'Shyuum formed [[Covenant religion|a religion]] around derelict vessel and other remnants of the Forerunners on their world. Eventually, [[War of Wills|a war]] was fought between [[Reformists|two]] [[Stoics|sects]] of the religion resulting in one of the sects boarding ''Anodyne Spirit'' and fleeing Janjur Qom.{{Ref/Book|Id=Enc22P190&191|Enc22|Page=190-191}}{{Ref/Reuse|Enc22P384&385}} After some time, the San'Shyuum encountered the [[Sangheili]]. Their differences in beliefs regarding the Forerunners led to [[War of Beginnings|another war]] that ended in a stalemate largely the result of the keyship's extreme power and resilience in battle compared to the Sangheili vessels.{{Ref/Reuse|Enc22P190&191}} Following this war, the [[Covenant]] was formed and ''Anodyne Spirit'' was decommissioned, becoming the centerpiece of [[High Charity]], the fledgling empire's capital.{{Ref/Reuse|Enc22P384&385}} There, it would power the massive [[space station]] up until the [[Great Schism]] in [[2552#November|November 2552]] when the [[Prophet of Truth]] appropriated the keyship to activate the [[Excession|Portal]] on [[Earth]] and travel to Installation 00 to activate the Halo Array. ''Anodyne Spirit'' was left in a region of the installation known as [[Mahsko]] with a detachment of [[Dhas Bhasvod's Covenant|Covenant forces]] led by [[Prelate]] [[Dhas Bhasvod]] assigned to guard it.{{Ref/Reuse|Sacrifice}}{{Ref/Novel|Id=DW|HDW}}

In [[2557#July|July 2557]], while on [[Triniel]] to get an [[upgrade seed]] for the ''[[Ace of Spades]]'', the crew visited a [[Builder]] facility where [[Rion Forge]] was drawn to the [[design seed]] for a keyship in a seed-building lab. Rion, who had a deep appreciation for starships, found it extraordinary to witness the plans for a vessel from an ancient alien race. [[343 Guilty Spark]] identified the design seed as belonging to a keyship for Rion before moving on to crafting the ''Ace of Spades'' upgrade seed using the lab's systems.{{Ref/Novel|HRen|Chapter=28}}

After their arrival to [[Installation 00]] on [[2558]], [[Colony]], two [[Mgalekgolo]] bond brothers that serve in the [[Banished]], began focusing much of their attention on the activities near the resting place of the keyships, without informing the other Banished leaders.{{Ref/Site|URL=https://www.halowaypoint.com/en-us/news/leggo-my-lekgolo|Site=Halo Waypoint|Page=Canon Fodder - Leggo my Lekgolo|D=30|M=06|Y=2021}}

In [[2559]], ''Anodyne Spirit'' found itself at the center of a conflict once again when a [[Banished]] raiding party [[Raid on Anodyne Spirit|infiltrated]] the keyship in search of a slipspace flake. While within the vessel, the Banished encountered Dhas Bhasvod's force and a bloody skirmish ensued.{{Ref/Novel|Id=Sacrifice|HSoR|Section=Adjunct|Detail=[[Sacrifice]]}} Following this, the Covenant loyalists emerged from the keyship and began to battle those fighting for control of Installation 00.{{Ref/Reuse|DW}}{{Ref/Reuse|Enc22P384&385}}
