Line Installation 1-4 (Earth-5875)

Line Installation 1-4 was a forerunner installation located in the moon LV-1201, deep within uncharted territory in the Orion Arm of the Milky Way galaxy.

History
Through history, multiple ships have been destroyed when passing near LV-1201.

In 2552, during the First Contact War, the ONI prowler UNSC Long Time Coming and the Covenant CAS-assault carrier Clarity of Faith were both gunned down by the defense systems of the installation while traveling in slipspace.

Their personnel were taken by the installation's Gatherer Sentinels and brought to the main facility of Line Installation 1-4 to be studied and dissected by the Monitor 686 Ebullient Prism. SPARTAN-II Black Team were able to escape and destroy the Monitor, as well as the stranded Covenant forces.
