That is the Ark, I believe I read it on the Weekly Update but it should be the Ark. The Ark isnt supposed to be a protector of Earth, its simply the Doomsday device that activates all the Halos simultaneously and pretty much wipes out the Galaxy. See activating a Halo only destroys all thats in a certain radius (I forgot how large), but in case of a major outbreak, the Ark is used to pretty much destroy everything, so thats why the Humans were still alive and everything in your theory because the Forerunners only activated one ring.
