| When the {{UNSCShip|Pillar of Autumn}}'s reactors detonated on [[2552#September|September 22, 2552]], Installation 04 attempted to activate a safety measure and make a slipspace jump. However, this self-preservation protocol was only partly successful, and only a small portion of the ring later designated Alpha Shard managed to enter slipspace before the ''Autumn''<nowiki>'</nowiki>s reactors overloaded and destroyed the ring. The surviving fragment of the Halo reentered normal space in the vicinity of [[Thotael system|Thotael]],{{Ref/Reuse|Enc22P345}} a red giant star some distance away from the [[Orrichon system]], and was caught in the star's orbit.{{Ref/Reuse|wp shard}} | | When the {{UNSCShip|Pillar of Autumn}}'s reactors went critical on [[2552#September|September 23, 2552]], Installation 04 attempted to activate a safety measure and make a slipspace jump.

| While most of Installation 04's debris either fell into [[Threshold]]'s or [[Basis]]' [[Gravity well (physics)|gravity wells]] or remained in the orbital debris field, at least 30% of the mass and curvature remained unaccounted for by the UNSC. In late [[2555]] the [[Office of Naval Intelligence]] took note of information recorded by an automated scout vehicle, [[Recon-14]], in an area designated Location 6201. Recon-14 had been deployed from the ''Pillar of Autumn'' before the ship's crash-landing on the Halo installation. The signal data from the drone was analyzed by multiple ONI specialists, among them ONI attaché for astrophysical phenomena [[Madeline Tress|Dr. Madeline Tress]]. She correctly concluded that the signal originated from the missing fragment of Installation 04, indicating that a part of the ring either generated or was enveloped in a significant slipspace event, one far exceeding the capabilities of either human or Covenant technology.{{Ref/Reuse|wp shard}} | | While most of the debris of Installation 04 either fell into [[Threshold]]'s or [[Basis]]' [[gravity well]]s or remained in the orbital debris field, at least 30% of the mass and curvature remained unaccounted for by the UNSC.

| Uniquely, the extreme heat of the ''Autumn''<nowiki>'</nowiki>s explosion, comparable to temperatures produced by a [[supernova]], caused the formation of an entirely new element known as [[Element 120.V]] in a small area of the fragment — one not found elsewhere in the known universe. This element was later illegally mined from the fragment and smuggled to [[Human colonies|human colonial space]], specifically the planet [[Sedra]]. It was discovered that the element caused catastrophic breakdown of DNA in certain humans but did not affect other species. The element was refined into a [[bioweapon]] which a [[Sangheili]] terrorist unleashed in [[Sedra City]], killing or hospitalizing many of the planet's citizens. A joint [[Locke's team|ONI]]-[[Sedran Colonial Guard]] team led by [[Randall Aiken|Colonel Randall Aiken]] and [[Jameson Locke|Lt. Commander Locke]] embarked on a [[Mission to Alpha Shard|mission]] to the Halo fragment in order to capture the smugglers who mined the element and destroy the deposits with a [[HAVOK]] nuclear warhead.{{Ref/Reuse|nf1}} However, the team became stranded on the shard, hunted by resident [[Lekgolo]] swarms that had commandeered and crashed their [[D81-LRT Condor]] dropship.{{Ref/Reuse|nf2}} Most of the group were killed during the mission and only two members—Lieutenant Commander Locke and [[Talitha Macer|Private Macer]]—made it off the shard aboard the smugglers' {{Class|Bactrian|freighter}} while Colonel Aiken sacrificed himself to manually detonate the HAVOK nuclear device, destroying the deposits.<ref name="nf3">'''Halo: Nightfall''', ''Chapter Three''</ref> | | Uniquely, the extreme heat of the ''Autumn''<nowiki>'</nowiki>s explosion, comparable to temperatures produced by a [[supernova]], caused the formation of an entirely new element in a small area of the fragment—one not found elsewhere in the universe.

| ==Description== | | ==Description== |
| Despite the extreme temperatures and radiation produced by its vicinity to the star the Halo shard has managed to sustain a habitable environment, although only when the terraformed side faces away from the star; the fragment's spin about itself produces a day-night cycle in which the terraformed side was in shadow for approximately sixteen hours, during which the temperatures remained high but survivable. However, when the habitable side rotated to face the star, not even the ring's systems could sustain livable temperatures or protect the occupants from the stellar radiation. Despite this, the UNSC took note of the ring's impressive redundant systems in functionalities including but not limited to those involved in maintaining gravitational field integrity, atmospheric composition, and even biodiversity levels.{{Ref/Reuse|wp shard}} While most of the shard's terrain was rocky and barren due to its extreme daytime temperatures, one particular area had managed to sustain a river and even simple moss-like vegetation. The vegetation was speculated to possibly not be a carbon-based lifeform which would explain its survival. While the river existed, it was shown to hold boiling water, even at nighttime when the shard was semi-habitable.{{Ref/Reuse|nf3}} | | Despite the extreme temperatures and radiation produced by its vicinity to the star, the Halo shard managed to sustain a habitable environment, although only when the terraformed side was facing away from the star; the fragment's spin about itself produced a day-night cycle in which the terraformed side was in shadow for approximately sixteen hours, during which the temperatures remained high but survivable.

| ==Production notes==
| |
| *In ''Halo: Nightfall'' Chapter One, [[Michael Horrigan]] states that Alpha Shard has a surface area of 96 km<sup>2</sup>. The depiction of the fragment clearly contradicts this: Installation 04's surface width alone is 318 kilometers and the fragment (based on its arc) appears to be at least several hundred kilometers long. This would result in a surface area of hundreds of thousands of square kilometers. However, this comment could simply refer to the size of the deposits themselves rather than the size of the shard.
| |
| *Though ''Nightfall'' does not clarify the issue, Alpha Shard appears to be the section of Installation 04 that is shown spinning into the other side of the ring at the end of ''[[Halo: Combat Evolved]]''.<ref>'''Halo: Combat Evolved''', campaign level ''[[The Maw]]''</ref> ''[[Halo 2: Anniversary]]'' revises the single large fragment into two smaller pieces,<ref>'''Halo 2: Anniversary''', campaign level ''[[The Heretic]]''</ref> either of which is a more likely candidate given the shard's apparent size.
