Human-Covenant War
During the Human-Covenant War in 2552, an Office of Naval Intelligence vessel, Long Time Coming, and a Covenant assault carrier, Clarity of Faith, crash-landed here after being disabled by the Line's weapon systems while in Slipspace. Some of their personnel were taken by Gatherers to Line Installation 1-4's main facility for study by 686 Ebullient Prism, the Monitor of the installation. They eventually managed to escape with the help of their compatriots and destroy the Monitor.
