== History ==

=== Ancient History ===

Installation 04 was built by the Forerunners over 100,000 years before the [[Battle of Installation 04]] (It was 101,217 years old in [[2552]] A.D., but this is measured in "local time").

The Covenant discovered the location of Installation 04 after the Covenant [[Fleet of Particular Justice]] followed the single [[UNSC]] cruiser, the {{UNSCShip|Pillar of Autumn}}, which was fleeing from the [[Fall of Reach]] through slipspace. It is assumed that the Covenant knew about the Ring prior to the events of The [[Battle of Installation 04]], as the [[Prophets]] all have a holographic representation of them on their headdresses and [[Cortana]] stated previously that she used the coordinates received by the beam in ''[[Halo: The Fall of Reach]]''. Due to the Covenant's faster [[Slipspace]] capabilities they arrived before the ''Pillar of Autumn''.  

Only a handful of humans and Covenant survived the battle. 343 Guilty Spark floated through space until he was rescued by a group of Covenant near [[Threshold]]. Inspired by his words, they began a [[Heretic]] rebellion against the greater Covenant. Installation 04's destruction is seen as the first step in the chain of events that led to the [[Covenant Civil War]]. The Heretics were quelled by The Arbiter who silenced their leader, but the seeds of a rebellion were planted. The Monitor was then captured by the loyal Covenant and later defected to the humans' side until he was destroyed on the replacement Alpha Halo by [[Spartan-117]] with the help of Sergeant Johnson.

There is now a large field of debris where Installation 04 was, though a few large chunks of the ring remain. Some smaller pieces of the Installation 04 have landed on [[Basis]] and others have burnt up in Threshold's atmosphere upon entry. The remaining large chunks are molten and unlikely to be capable of supporting any kind of life and are thus likely free of Flood.

===Replacement===

Shortly after the destruction of the [[Halo]], the [[Ark]] began to automatically construct a new Halo to replace Installation 04. This exact copy of the first Halo ring was nearing completion only a few months after the first ring was destroyed, but was also subsequently destroyed when it was fired before it was ready by the [[Master Chief]] and [[Cortana (AI)|Cortana]].  343 Guilty Spark attempted to prevent this, but was finally destroyed by the Master Chief with the help of Sergeant Johnson in this new ring's [[Control Room]].

Circumstantial evidence from [[Bungie]] indicates that Alpha Halo may be located in the [[Soell|Iota Horologii]] System, only 50 Light years from Earth.{{verify source}}

== Speculation ==

It is unclear why the gas giant [[Threshold]] was specifically chosen to be the planet which Installation 04 orbited, but it is supposed that the large number of [[Forerunner]] machines already operational in Threshold (explicitly the network of Gas Mines), may have played a role in their decision. It could also be because it was the only planet in the system that had enough gravity to hold [[Halo]] in place.  

After the destruction of Installation 04, [[Spartan-117]] and [[Cortana]], who were responsible for the ring's destruction, fled the installation in a [[Longsword]]. Shortly afterward, they reunited with four other survivors on a [[D77-TC Pelican Dropship|Pelican]]. The survivors of the [[Battle of Installation 04]] were as follows:

* [[Master Chief Petty Officer]] [[John 117]]

* [[UNSC]] [[AI]] [[Cortana]]

* [[Sergeant Major]] [[Avery J. Johnson]]

* [[Corporal Locklear]]
