Editing Site Z

{{Status|Canon}}
'''Site Z''' is an [[Office of Naval Intelligence]] research facility located on the [[Human colonies|frontier world]] of [[Nysa]]. It is one of many [[United Nations Space Command]] (UNSC) military facilities located on the world, originally built and hidden early in the [[Human-Covenant War]] for use as a secretive fallback point for the UNSC. The site is located several kilometres from the [[Avery J. Johnson Academy of Military Science]], in the [[Hesychius Mountains]].{{Ref/Novel|Id=ET11|ET|Chapter=11}}

==Overview==
Site Z is one of many ONI facilities present on Nysa, with the Avery Johnson [[Spartan]] academy itself built atop another critical [[ONI Section Three]] site. As of the [[2560]]s, the ONI facilities beneath the Avery Johnson academy remain unmapped, with the base's Commander [[Laurette Agryna]] suspecting that they connect to outlying sites like Site Z - a security issue that would ultimately prove fatal during the [[Banished]] invasion of the planet in early 2560.{{Ref/Novel|Id=BFTA1|Halo: Battle for the Academy - Part 1}}{{Ref/Novel|Id=BFTA2|Halo: Battle for the Academy - Part 2}} The base's secrecy was such that even Admiral [[Serin Osman]], the [[Commander-in-Chief of the Office of Naval Intelligence]] (CINCONI), was unaware of its existence.{{Ref/Reuse|ET11}}

The base itself is, externally, rather simple and unassuming: it consists of several modest grey two-floor buildings encircling a single bare [[landing pad]] like a wreath. However, this presence belies an extensive underground presence at the site, with at least three underground floors - the third of which the busiest and containing a beltway corridor that connects the surface buildings together. This floor also contains a secure meeting room named ''Eudoxus'' (named after the [[Wikipedia:Eudoxus of Cnidus|Greek mathematician]]), a roughly {{Convert|5|m|ft}}-wide hexagonal room filled with data displays and requiring a hand scan to open. The centre of the room has a table which can be raised or lowered into, and under, the floor; during military briefings this means that a valuable item (such as a [[personal computer]] can be kept out of reach of meeting attendees while still allowing an [[artificial intelligence]] construct to communicate. The room is capable of projecting an [[energy barrier]] in the centre; this can be used to contain an explosive blast.{{Ref/Reuse|ET11}}

The base is usually lightly-staffed, with security provided by the [[SPARTAN-IV program|SPARTAN-IVs]] of the nearby Avery Johnson academy.{{Ref/Reuse|ET11}}

==History==
Site Z was presumably constructed alongside the rest of the ONI presence on Nysa during the early stages of the [[Human-Covenant War]]. At the time, Nysa was kept a secret despite its status as a potentially-ideal civilian colony in order to keep it useful as a fallback point for the UNSC in the war effort. This usage transitioned into the [[Post-Covenant War conflicts|post-war years]], with the site (and world) remaining operation into the [[Created uprising]]. On [[2559#November|November 19, 2559]], Site Z was the location of an important strategic meeting conducted between the UNSC and [[Swords of Sanghelios]]. Both organisations had independently converged on the knowledge of the [[Order of Restoration]] and their plan to acquire the [[Lithos]], a [[Forerunner]] artefact that would allow them to control the [[Domain]] after [[Cortana]] and the [[Created]] (the then-current custodians of the Domain)'s defeat. During the visit, Spartan Commander Agrnya was evidently uncomfortable with admitting [[Sangheili]] into the base due to her own distrust, and as such personally escorted the Swords party: Shipmasters [[Rtas 'Vadum]] and [[Mahkee 'Chava]], [[Vul 'Soran]], and [[Tul 'Juran]], with Admiral [[Jilan al-Cygni]] into the ''Eudoxus'' meeting chamber. Spartans were posted at guards at every intersection inside the base.{{Ref/Reuse|ET11}}

The meeting itself involved the aforementioned alongside Captain [[Abigail Cole]] and Admirals Osman, and [[Terrence Hood]], with the focus involving the extraction of critical information from the AI [[Black-Box]]. Black-Box had been sequestered with Hood and Osman on a [[Rossbach's World|remote world]] for the previous year, and so the meeting served to help bring admirals Osman and Hood up to speed while also giving the UNSC and Swords a chance to discuss how to proceed. This concluded with the deployment of Cole's {{Class|Valiant|super-heavy cruiser}} {{UNSCShip|Victory of Samothrace}} and 'Vadum's {{Pattern|Kerel|assault carrier}} ''[[Shadow of Intent]]'' to [[Venezia]], where they would ultimately [[Battle of Venezia|engage in combat]] with War Chief [[Severan]] and the [[Vanguard of Zaladon]].{{Ref/Reuse|ET11}}

In [[2560#March|March 2560]], Nysa was [[Battle of Nysa|attacked and occupied]] by the [[Banished]], with a particular focus on the Avery Johnson Academy. While the status of Site Z during the invasion is unknown, its proximity to the academy means it was likely similarly-attacked and destroyed. It is unknown whether Site Z is one of the academy's several outlying facilities that were able to enact the [[Cole Protocol]] during the invasion.{{Ref/Reuse|BFTA2}}
