[@Ti] I like your attitude!

That's honestly what at least some of the inspiration comes from, just in this case, the sea of clouds isn't really a sea, it's just clouds, and the idea is that the technology will advance drastically over time, especially as they discover ruins of the old world and bring up 'ancient' technology. So while they just start out in power armor... who knows where they'd be by the end. I mean by the end... who is to say they're even facing the same threats.
