I am a work in progress...
Because humanity was screwed over by the covenant wouldn't they have a special place kind of like a bomb-shelter were the most important people and there select few would retreat to? Because I learned on the History channel *it does wonders* that during the Cold war in case of a nuclear attack the President and his select 30 individuals would go into a bomb shelter that is about an hour away from DC well wouldn't the humans of the future also hide there most important's? Where do you think they would hide em?
Note: Thsi has nothing at all to do with Halo and MC but more of the Time and the Technology
