Editing Containment shield

{{Status|Canon}}

During the [[Battle of Installation 05]], the containment shield kept [[United Nations Space Command|UNSC]] and [[Covenant]] forces stationed on Delta Halo from reaching the [[Activation Index|Index]]. In order to gain access to the Library and retrieve the Index, the [[Hierarchs]] of the Covenant dispatched [[Arbiter]] [[Thel 'Vadam]]ee to lower the shield. The Arbiter fought his way through the [[Aggressor Sentinel|Sentinel]] defenders to the enormous chamber containing the controls for the barrier. After destroying the Sentinel [[Enforcer]] guarding the chamber, the Arbiter retracted four [[piston]]-like [[plug lock]]s which unlocked the main control panel, allowing him to lower the shield. This caused the entire two-tiered control platform to move to the other side of a large chasm in the middle of the Sentinel Wall in a manner similar to an [[anti-gravity gondola]].{{Ref/Reuse|h2}}

The deactivation of the shield allowed access to the Quarantine Zone by the Covenant and the UNSC, which also gave the Flood hundreds of new hosts. The Flood was released onto the rest of [[Installation 05]]. As a result of this, the {{UNSCShip|In Amber Clad}} was taken over by the Flood and flown into the Covenant holy city of [[High Charity]].{{Ref/Reuse|h2}}

In [[2552#December|December 2552]], three days after the [[Human-Covenant War]] ended, [[monitor]] [[000 Tragic Solitude]] had a containment shield set up around the ruins of [[High Charity]] to contain the [[Flood]] that had survived the detonation of the city's reactors and the firing of [[Installation 08]]. As an additional security measure, Tragic Solitude had the Sentinels raze the perimeter and modify the refugia to ensure that no sentient life survived nearby, in order to deprive the Flood of any host bodies in proximity to their prison. Tragic Solitude also kept a battalion of Sentinels on patrol in the vicinity of the containment shield, not only to guard against the Flood, but to guard against future invaders who might try to breach the shield and thus release the Flood.<ref>'''[[Halo Wars 2]]''' ''[[Phoenix Logs]]'' - ''Idle Hands II''</ref>

During the [[Second Ark Conflict]] in [[2559#June|June 2559]], [[Atriox]], the leader of the [[Banished]], ordered [[Jiralhanae]] brothers [[Pavium]] and [[Voridus]] to salvage anything useful from the shipwrecks near High Charity, but to only scout the shell and leave it alone, well-aware of the danger posed by any surviving Flood. However, like many of the Banished, Voridus brushed off the Flood as another Covenant lie and didn't heed Atriox's warnings. Instead, Voridus deactivated the Ark's Sentinel defense network using a terminal near High Charity and burned a hole in the containment shield with a [[Barukaza Workshop Scarab]]. When Voridus' troops entered the wreckage, they were swarmed by Flood [[infection form]]s which attacked the Banished and escaped onto the Ark through the breach in the containment shield created by Voridus, unimpeded by the Ark's Sentinels due to Voridus deactivating them.<ref>'''[[Halo Wars 2: Awakening the Nightmare]]''', campaign level ''[[What Could Go Wrong?]]''</ref>

 

Voridus eventually managed to reactivate the Sentinel defense network<ref>'''[[Halo Wars 2: Awakening the Nightmare]]''', campaign level ''[[The Archive]]''</ref> and the Banished, with the help of the Sentinels, slew a [[Proto-Gravemind]] that the Flood formed before it could become a full-fledged [[Gravemind]]. With the Sentinel defense network reactivated, thousands of Sentinels began a cleansing operation, supported by the Banished. The Sentinels and the Banished were able to contain the Flood outbreak<ref>'''[[Halo Wars 2: Awakening the Nightmare]]''', campaign level ''[[Manifestation]]''</ref> and scour them from High Charity's ruins.{{Ref/Novel|SoR|Detail=''[[Sacrifice]]''}}
