I wouldn't be surprised if the story had Halsey go through a sex change and use a civilian variant of the MJOLNIR armour to hide herself from ONI while working in an underground Halo. All the while the Elites are pillanging and making humans their pet slaves in colony planets one by one. With CerberONI making a contingency plan to indoctrinate the Brute youths through free education and healthcare all the way up to university [Welcome to the good life] to pass around propaganda at the Elites. Meanwhile Master Chief has been cloned several times, as a safe measure agaisnt atheism that is prevalent during this galactic scientific age. The second coming of Christ is announced as Cheif returns to Earth after the apocalytic events of Halo 4,5 and 6, but this time, his armour upgrades are beyond MJOLNIR, they turn into this MANTIS MECH VII, this variant is 3000 ft tall. [u]All must bow down to Master Jesus Cheif 117.[/u] In recognition of Halsey recent persecution she is seen in the same light as the Virgin Mary... turned man. Faith is finally restored. The Halo church gets busy and begins the new new testiment of greater great journey.
