Editing Sentinel manufacturing facility

{{Status|Canon}}

[[Installation 00|The Ark]]'s Sentinel factories are linked to the installation's Sentinel defense network. When war-chief [[Voridus]] of the [[Banished]] disabled the network, it could not produce Sentinels, resulting in the Flood clogging many of the manufacturing facilities with biomass. The Banished cleared one of the main manufacturing facilities, enabling them to call in a [[Retriever Sentinel]] in order to defeat a [[Proto-Gravemind]].

The Sentinel factories seen on [[Installation 05]] were massive, floating structures that hovered above the [[Halo Array|Halo ring]]'s surface in an attempt to keep them somewhat safe from the majority of ground-based [[Flood]] forms in the event of a major outbreak. These facilities were used during the Flood outbreak on Installation 05, and could be seen in the sky above the [[Quarantine zone (location)|quarantine zone]] around the installation's [[Library]]. One of these facilities was destroyed by the Flood during the [[Battle of the Quarantine Zone]].<ref>'''Halo 2''', campaign level ''[[Sacred Icon]]''</ref> Its wreckage was later traversed by [[Arbiter]] [[Thel 'Vadam]] on his way to the Library.<ref>'''Halo 2''', campaign level ''[[Quarantine Zone]]''</ref>

The [[shield world]] [[Onyx]] contained a massive Sentinel factory located underneath a volcanic caldera in its north pole,<ref>'''Halo: Ghosts of Onyx''', ''page 313''</ref> which produced the huge number of specialized [[Onyx Sentinel]]s that made up the artificial planet's superstructure. The facility was so large that the arc of the planet's curve could be seen in the distance.{{Ref/Reuse|goo315}} The Sentinels in this facility were constructed out of molten ore spewed from a massive machine, which cascaded into a hollow tower. From the bottom of this tower tumbled millions of Sentinel components, which then were ferried to another part of the factory by energy beams. As they traveled, they assembled themselves into the three-meter long "booms" of the Onyx Sentinels. The central chamber housed a pyramid-shaped structure described as being "five times the height of the [[Wikipedia:Great Pyramid of Giza|Great Pyramid of Giza]]", which was composed of the "eye" spheres of the Sentinels.{{Ref/Reuse|goo315}} Every six seconds a sphere from the apex of the pyramid ascended in a shaft of silver light. When the spheres emerged, they had been assembled into a complete [[Onyx Sentinel]].<ref name="goo316">'''Halo: Ghosts of Onyx''', ''page 316''</ref>

The facility was heavily defended, with clouds of Onyx Sentinels hovering over the construction plant.{{Ref/Reuse|goo316}} The factory produced a new Sentinel every six seconds, quickly making enough Sentinels to combat any known threat.{{Ref/Reuse|goo316}} The factory was accessible through the local [[teleportation grid]], and several [[teleporter]]s were located across the facility for rapid transportation.<ref>'''Halo: Ghosts of Onyx''', ''page 318''</ref> The manufacturing plant was later destroyed by [[SPARTAN-II program|SPARTAN-IIs]] and [[SPARTAN-III program|IIIs]] to halt the production of Sentinels on Onyx.<ref>'''Halo: Ghosts of Onyx''', ''page 324''</ref>

The [[shield world]] known as [[Trove]], discovered by the crew of the {{UNSCShip|Spirit of Fire}} in [[2531]], had [[Sentinel factory|several types]] of underground Sentinel factories, which created Sentinel [[Aggressor Sentinel|Aggressors]] and [[Protector Sentinel|Protectors]].<ref>'''[[Halo Wars]]'''</ref>

In ''[[Halo 2: Anniversary]]'', on the campaign level ''[[Quarantine Zone]]'', the [[terminal/Halo 2: Anniversary|terminal]] can be found in the first part of the wrecked Sentinel manufacturing facility.
