At the closing days of the Flood-Forerunner War, we know that the Didact, specifically Bornstellar-Makes-Eternal-Lasting, initiated the Halo Arrays from the Lesser Ark, Installation 00… decimating all life in the Milky Way Galaxy.
Upon the wake of the Installation’s destruction, the remaining Forerunners, reseeded all sentient life, and prosecuted the Contender-class Ancilla, 032 Mendicant Bias… who was found guilty, scattered into fragments and imprisoned beneath the sands of Installation 00, with only his own atonement to consolidate him… After performing their final tasks, the Forerunner decided to never interfere with the Milky Way Galaxy ever again… and went on a Great Journey… to which was to be a reflection of their sins to the Mantle. The specified location however was unknown and remains a mystery…
Known Forerunner Exiles are:
- The Iso-Didact, Bornstellar-Makes-Eternal-Lasting.
- The Lifeshaper, Chant-To-Green.
The location has been speculated by the Halo fanbase for a while… and a recurring factor is the Magellanic Clouds… And so upon this discovery, I did some research into what these might be… in short, they are satellite galaxies which orbit the Milky Way… two known clouds exist, a Greater and a Lesser… Path Kethona and Pax Kethona (Placeholder name) respectively.
Now this smaller galaxy… is of unknown characteristics so perhaps this location could be a possibility?
The Greater Magellanic Cloud, Path Kethona, was said to be the ‘origin’ of the Flood Legion, and also were they may have retreated too, during the Human-Forerunner War… it would seem more suitable as it already had, Forerunner inhabitants. Yet, it was also made into a hazardous environment due to Master Builder Faber pre-maturely firing Omega Halo , to test the effects on Precursor technology and local sentient life.
My theory is the Forerunners after reseeding and dealing with the traitorous ancilla, could have moved their Capital to Pax Kethona to live…
This theory comes from the fact that the Capital, is just way to large to be hidden… it has never been discovered by Covenant, or Human Empires? How could something that large… be hidden for so long? It was never destroyed by the Flood, just overrun… and so once the Installations fired, they would have destroyed the Flood presence upon the Capital allowing it to relocate and be re-colonized by the remaining Forerunner.
