When the ''Pillar of Autumn''{{'}}s reactors went critical, 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 managed to enter slipspace before the ''Autumn''{{'}}s reactors overloaded and destroyed the ring. The surviving fragment of the Halo reentered normal space in the vicinity of a red giant star some distance away from the [[Orrichon system]] and was caught in the giant star's orbit.<ref name="wp shard">[https://www.halowaypoint.com/en-us/universe/locations/halo-ring-fragment '''Halo Waypoint - Universe''': ''Alpha Shard'']</ref> This fragment was home to a unique element apparently created by the heat of the ring's explosion and not found elsewhere in the universe. The element was later refined and used in a [[bioweapon]] unleashed in a [[terrorist]] attack on [[Sedra City]].<ref name="nf1">'''Halo: Nightfall''' - ''Chapter One''</ref> [[Mission to Alpha Shard|A joint classified mission]] was launched to Alpha Shard by an [[Locke's team|ONI team]] and members of the [[Sedran Colonial Guard]].

During the {{UNSCShip|Spirit of Fire}}'s [[Second Ark Conflict|battle]] with the [[Banished]] at the Ark in [[2559#March|March 2559]], Captain [[James Cutter]], Professor [[Ellen Anders]], and logistics AI [[Isabel]] formed a plan to deploy the second replacement for Alpha Halo, Installation 09, to the Soell system in an attempt to send a [[distress beacon|distress signal]] to [[Human colonies|human space]].<ref>'''[[Halo Wars 2]]''', campaign level ''[[Hold the Line]]''</ref> On the way to the original site of Installation 04 however, a Forerunner [[Guardian|Guardian construct]] controlled by Cortana's [[Created]] intercepted the ring.<ref>'''Halo Wars 2''', campaign level ''[[Last Stand (Halo Wars 2 level)|Last Stand]]''</ref>

Installation 04 also underwent a number of visual changes in ''[[Halo 2: Anniversary]]'', including the addition of blue lighting in the circular patterns on the ring's outer surface. Curiously, [[Installation 05]] in the same game uses a distinct model, which bears different surface patterning more closely modeled after that in [[Bungie]]'s games but is noticeably wider than either the Installation 04 model in ''Halo 2 Anniversary'' or the Halos in prior media. Furthermore, [[Blur Studio]] used Installation 05's model, rather than that of the original Installation 04, from ''Halo 2 Anniversary'' for [[Installation 09]] in ''[[Halo Wars 2]]''.<ref>'''Halo 2 Anniversary''', [[:File:H2A_-_DeltaHalo.jpg|''Delta Halo model'']]</ref><ref>'''Halo Wars 2''', [[:File:HW2 I04C.png|''Installation 09 model'']]</ref>
