Replacement

The replacement Halo installation was built due to it's original being destroyed by Master Chief (John 117) being a replacement ring. Apparently it was first discovered aboard the Ark firstly by The Arbiter and John-117. It also so happens that this replacement structure was in an incomplete state in which it was first discovered originally to be completed in approximately a few day according to monitor 343 guilty spark. Interestingly the Halo installation was certainly similar to it's original through Control Room environment also possessing the exact same monitor as the original. However this particular installation was destroyed shortly after it's discovery and directly after the combat between 343 guilty spark and Master Chief along with the arbiter and Sergeant Johnson as a result of Cortana firing prematurely which in the process destroyed the Ark.
