I wonder if this is part of a cyclical history and this is how we ended up with kings/nobility in the first place? Like we’ve been in this situation before where the Earth’s climate goes to shit and the only people with the resources to make it through the Dark Ages are this class of wealthy individuals who were also the cause of the Dark Ages, but were able to build bunkers/castles to make it through their obscene wealth that they had accumulated.

So at some point in a few hundred years, we’ll have these kingdoms carved out, all centered on these new tech billionaires and other families that were able to carve out their own fiefdoms. I’d love to see a “fantasy” series that starts out as sort of typical Fantasy, with maybe medieval technology, but then gradually over time it’s revealed that they’re survivors of a post-apocalypse (though I’m sure it’s been around for decades, I know Gene Wolfe’s Book of the New Sun series kind of fits in that realm, along with Dungeon Crawl Classics for an RPG). The “Great Families” will be revealed to be the Musks, Gates’, Bezos’, Zuckerburgs, Ballmers, Ellisons, Pages, and whoever else has been building their own bunkers in secret.
