Before its destruction, Alpha Halo orbited a large gas giant known as Threshold (Earth Survey Catalogue Number B1008-AG), anchored at the L1 Lagrange point between the planet and its largest moon, Basis. An extensive network of Forerunner gas mining and refinery stations was suspended in the atmosphere through a number of band
While Basis is by far its largest moon, eleven other satellites orbit Threshold. These satellites have not been extensively surveyed, though all but two appear to either house some sort of Forerunner installation or are entirely artificial. The function that these outposts served remains unknown, but most evidence indicates they provided maintenance for Alpha Halo.
A 500 light-second exclusion zone is currently maintained around Threshold, with both Sangheili and human warships patrolling the region as part of the post-war treaty between those species.
