Forum talk:Why only the seven Halo Rings?

True, but I just read the page here on Halopedia all about the Halo Array. Evidently there were two different arrays (two sets of rings). The Ark was built with the second array, which contained only 6 rings. The twelve I talked about earlier were the first and biggest installations. When Mendicant Bias attacked the Capitol, the twelve original rings were there (including the one Mendicant Bias brought with him). During the battle, the Forerunners managed to destroy one, seven were recalled to the Ark, only one made it through, becoming the seventh installation. Another was destroyed by a third Ring attempting to go into the portal at the same time, presumably the third Ring was destroyed or heavily damaged as well. The status of the other eight Halo Rings is currently unknown. Seeing as the Mendicant Bias did not have an installation with him when he broke the Maginot Line, it can be assumed the other installations fell back into Forerunner hands, were destroyed ir severely damaged.
