Questions about the current reality

Alright, been a fan of the show for sometime really enjoying but I wanted to share some thoughts with folks I had after watching and then rewatching and starting season 2 ep 1

The world we’re seeing is post-something right? The centering of Kier is notable. He’s apparently iconoclastic, cult leader, settler or something? The town they all live in is named after him, and we don’t have a Kier, PE in our current reality. But, there is a Topeka of some kind because there’s a newspaper coming out of there.

Also, on the very first episode he asked Helly R what states she could name and she landed on Delaware? But couldn’t think of any others. I’m wondering if this is an effort to restore people from a big war or some sort of fallout from a previous time. Even the people at the party where Mark discovers his dead wife is alive, the people seem… off.

Anyone know where I’m coming from?
