Installation 00

Installation 00, also known as the Ark and sometimes translated as Waypoint, is a Forerunner installation from which the entirety of the Halo Array can be activated. Installation 00 also functions as a potential safe haven from the Halo Array's strategic pulse, and as a facility to construct replacement Halos if necessary. The Ark is situated outside the galaxy, approximately 218 (262,144) light years from the galactic center.
