What is the bunker good for? Are they just going to live their little lives eating preserved food or will they have an army that controls the surrounding lands like a feudal lord? What's the long term plan here?
One thing we've learned during covid lockdowns is that most people aren't really able to live locked up in a bunker for too long. I imagine this is especially true for narcissistic people who are used to having their every whim catered to. So yeah, don't see what they're thinking there either to be honest.
