I was reading and someone made the point that building the Halo's would be quite costly so what if the Rings were already there or something like them and they were Forerunner military bases I think the Rings are to small to support a large civilian population. Forerunners added the landing bays and stuff on the outside of the ring as the Military Installations became larger. The forerunners encountered the flood and are pushed back like humanity is being pushed back now. The rings might have been in roughly the center of there Empire and the flood slowly enchroched on the rings. The Forerunners realized they probably will be wiped out so they needed to stop the flood. The Forerunners then built the the doomsday weapons on the 7 rings and when all tactical options have been depleted and the Flood were on the rings the Forerunners whos doom was within months mabye even weeks or days activated the the rings weapons wiping out all creatures largest enough to sustain the flood which would mean the Flood combat and the the carrier forms were destryoed. Through a loop hole or design the ranger flood were not destroyed. Or the installations were where they kept flood prisoners and also where the Forerunner last resort weapon was.
