The Maginot Line, or Jat-Krula as it was known to the Forerunners, was constructed over half a million years before the firing of the [[Halo Array]] as the ultimate defense for the inner systems of the [[ecumene]]. The Line installations, arranged in sets of four and numbering in the millions in total, were placed in strategic locations, particularly along the most efficient and well-known slipspace pathways, forming an enormous spherical territory surrounding the Orion complex. Any incoming enemy ship or [[Forerunner fleet|fleet]] would have to pass through the perimeter,{{Ref/Reuse|sil104}} where it would be trapped, seized or destroyed by the Line installations in range.<ref name="h4evg">'''[[Halo 4: The Essential Visual Guide]]''', ''page 221''</ref>  

 

As part of the Forerunners' efforts to contain and understand the [[Flood]], some Line installations were refitted to serve as [[Flood research facility|Flood research facilities]]. These installations employ machines known as [[Gatherer]]s, specialized for collecting specimens for analysis. Each Line installation also has its own [[monitor]] and a control center, as well as a sizable force of [[Sentinel Aggressor|Sentinels]].{{Ref/Reuse|blood1}}

During the [[Forerunner-Flood war]], Line installations were used as containment measures against [[Flood]]-controlled spacecraft, meant to prevent them from reaching the Forerunner core worlds.{{Ref/Reuse|wreckage}} However, in the later years of the war, even these measures began to fail and the Flood would occasionally slip past gaps created in some segments of the boundary.<ref>'''Halo: Silentium''', ''page 193''</ref> A number of Line installations remained active following the Forerunners' disappearance, and continued to intercept spacecraft of future civilizations that passed near them over the next hundred millennia.{{Ref/Reuse|blood1}}{{Ref/Reuse|wreckage}}

During the [[Human-Covenant War]] in the late [[2552]], the [[ONI]]-commissioned mining ship ''[[Long Time Coming]]'', as well as the [[Covenant assault carrier]] ''[[Clarity of Faith]]'' were shot down by [[Line Installation 1-4]]'s defenses while in Slipspace. Both of the ships crash-landed on a [[Unidentified moon (Sub-sector 35)|moon]] in [[Sub-sector 35]] on which the Line installation was located.{{Ref/Reuse|blood1}} Personnel were taken by Gatherers into the main facility of the installation, for study by the installation's Monitor, [[686 Ebullient Prism]].<ref>'''Halo: Blood Line''' ''[[Halo: Blood Line Issue 3|Issue 3]]''</ref> During the [[Battle of Line Installation 1-4]], the installation's control center was located and used by [[Team Black]] to shoot down an entire [[Covenant fleet]] in Slipspace.<ref>'''Halo: Blood Line''', ''[[Halo: Blood Line Issue 5|Issue 5]]''</ref>

[[Line Installation 9-12]] was discovered more recently, when a group of scavengers were stranded on its surface. Setting up a makeshift camp, the scavengers sought to uncover valuable artifacts from the surface of the world. However, they subsequently disappeared, leaving behind only their final transmissions, which included detailed environment scans of the Line installation. These scans were later appropriated as a [[Spartan Operations|Spartan]] [[War Games]] training environment designated ''[[Wreckage|War Games Map_Set/: 893-3]]'' aboard {{UNSCShip|Infinity}}.{{Ref/Reuse|h4evg}}

In ''[[Halo: Blood Line]]'', the main control center of [[Line Installation 1-4]] is modeled after the [[Relic (location)|relic]] on [[Harvest]]. While this may be an instance of the artist using existing visual reference material without fictional considerations, it may suggest that the Relic is in fact a Line installation.
