The '''''Supernal Spiral''-class keyship''' is the most common classification of [[Forerunner]] [[keyship]].{{Ref/Reuse|Enc22P384&385}} Vessels of this class were used during and after the [[Forerunner-Flood war]] to collect specimens from various [[planet]]s, safely transport them to [[Installation 00]], and then return to those same worlds to reseed them with life following the [[Great Purification|activation]] of the [[Halo Array]].{{Ref/Reuse|Legends}}{{Ref/Reuse|WF}}{{Ref/Reuse|Enc22P384&385}} As is implied by its classification, these ships can act as keys to activate [[slipspace portal]]s place in strategic locations throughout the [[Milky Way]].{{Ref/Reuse|TheStorm}}{{Ref/Reuse|Enc22P384&385}}

The most notable of the ''Supernal Spiral''-class keyships is ''[[Anodyne Spirit]]'', or "Forerunner Dreadnought" as it was known by the [[Covenant]]. Originally assisting with the [[Conservation Measure]], ''Anodyne Spirit'' crashed on the [[San'Shyuum]] homeworld of [[Janjur Qom]] where it became the focal point of their religion, ultimately kickstarting the formation of the Covenant and later becoming the centerpiece of their holy city of [[High Charity]].{{Ref/Reuse|Enc22P190&191}}{{Ref/Reuse|Enc22P384&385}}

==Design details==
===Hull and superstructure===
''Supernal Spiral''-class keyships are geometric and angular, having a tetrahedral shape consisting of a forward triangular prow with three similarly-shaped struts jutting out from its Primal Crux.{{Ref/Novel|Id=Sacrifice|HSoR|Detail=Adjunct - [[Sacrifice]]}}{{Ref/Reuse|Enc22P384&385}} Their hulls are gray and silver in color. While most [[Forerunner]] vessels crafted by the [[Builder]]s could reform themselves into different geometries, the form of the ''Supernal Spiral''-class keyship was fixed,{{Ref/Reuse|WF}}{{Ref/Reuse|Enc22P384&385}} maximizing strength and unity of purpose at the cost of flexibility. When resting on its landing struts, the ''Supernal Spiral''-class keyship has a height of 13,120 meters, a width of 12,441 meters, and a length of 10,774 meters.{{Ref/Reuse|WF}} Its total mass is 19 billion metric tons.{{Ref/Reuse|WF}}{{Ref/Reuse|Enc22P384&385}}

===Internal layout===
As would be expected given their massive size, the interior of ''Supernal Spiral''-class keyships consist of numerous rooms, many of which are docking bays and control rooms, including command chambers that are many stories high.{{Ref/Reuse|Sacrifice}}{{Ref/Comic|HU}} A series of [[Elevator|lift]]s allow access to many levels of the interior of the ship.{{Ref/Reuse|Sacrifice}} The three landing struts store the ship's [[cylix]] specimen receptacles within large, cavernous rooms.{{Ref/Reuse|WF}} A location of note within the vessel is the Adytum, where the [[slipspace flake]] used to open [[slipspace portal]]s is stored.{{Ref/Reuse|Sacrifice}}

===Armament and defense===
Despite their purpose of conservation, ''Supernal Spiral''-class keyships are equipped with powerful weapon systems including a single [[light mass fusillade cannon]] and three [[anti-ship artillery system]]s.{{Ref/Reuse|WF}}{{Ref/Reuse|Enc22P384&385}} As the [[San'Shyuum]] [[Reformists]] could not access these systems on ''[[Anodyne Spirit]]'', they modified the vessel with their own weapons, using the keyship's own energy systems to give the weapons extreme power.{{Ref/Reuse|hbc weapons}} However, these weapons were removed when the keyship was later decommissioned.{{Ref/Novel|HCH|Chapter=9}}

While the ''Supernal Spiral''-class keyship's primary defense is its speed and agility, they are fitted with an extensive suite of defensive countermeasures including a powerful [[energy shielding|prime dispersal field generator]].{{Ref/Reuse|Enc22P384&385}} They are even fitted with the ability to remotely detonate the ship to prevent its capture by the [[Flood]]. In [[2552]], ''Anodyne Spirit''{{'}}s shielding appeared impervious to even the heaviest of [[United Nations Space Command]] shipborne armaments, notably even [[Magnetic Accelerator Cannon]]s.{{Ref/Level|Id=TheStorm|H3|[[The Storm]]}}

===Crew and complement===
In the Forerunner era, ''Supernal Spiral''-class keyships were operated by a crew of one [[princeps|princep]], three [[navarch]]s, one [[archmedicus]], and 560 [[adjutant]]s. They also carried a complement of 100 [[Scutarii]], 1,224 [[Strato-Sentinel]]s, 48 {{Class|Strix|harrier}}s, and 890,000 [[Sentinel]]s and [[weapon-ship]]s.{{Ref/Reuse|WF}}

==History==
[[File:Keysip.png|300px|thumb|A group of ''Supernal Spiral''-class keyships on their way to reseed life in the galaxy.]]
===Forerunner-Flood war===
The ''Supernal Spiral''-class keyship was designed by naval architects [[Grasping-Steady-Firmament]] and [[Lightning-Weaving-Helix]], and was manufactured within the enormous production corridors of the [[Ingens Assembler Vats]]. During the [[Forerunner-Flood war]], the ''Supernal Spiral''-class keyship became the most established and prominently utilized class of keyship.{{Ref/Reuse|Enc22P384&385}}

They were an integral part of the [[Lifeworker]]s' [[Conservation Measure]], helping to preserve sentient life within the [[Milky Way]]. Before the firing of the [[Halo Array]], the Forerunners used these keyships to gather specimens of sentient species located throughout the galaxy, transporting them to [[Installation 00]] to protect them from the [[Flood]] and also the devastating effects of Halo.{{Ref/Reuse|Enc22P384&385}} After the seven ringworlds fired out their pulses, many ''Supernal Spiral''-class keyships, containing preserved specimens of each species, were sent to the planets from which the sentient species originated, releasing a population of the species on their planet of origin.{{Ref/Film|Id=Legends|HLeg|Episode=Origins}} Upon finishing their mission, the keyships returned to Installation 00.{{Ref/Reuse|WF}}{{Ref/Reuse|Enc22P384&385}}

[[File:HM WarOfWills.jpg|300px|left|thumb|The San'Shyuum fight for control of ''Anodyne Spirit''.]]
===Legacy===
After ''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]]ity, 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 [[Portal at Voi|Portal]] on [[Earth]] and travel to Installation 00 to activate the Halo Array. The ''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}} They dutifully remained within the keyship until the [[Second Ark Conflict]] in [[2559]] when a [[Banished]] raiding party [[Raid on Anodyne Spirit|infiltrated]] ''Anodyne Spirit'' in search of a slipspace flake.{{Ref/Reuse|Sacrifice}} Following this, the Covenant loyalists emerged from the keyship and began to wage war against those fighting for control of Installation 00.{{Ref/Reuse|DW}}{{Ref/Reuse|Enc22P384&385}}
