Maybe we should be building our citadels underground.

I remember digging a giant deep hole with some friends out on the farm growing up.

I haven't done much digging but it doesn't take much effort to understand that it'd be rewarding. I used to watch videos of primitive homes being built in jungles to relax

Maybe we can start a town like Coober Pedy

I wonder if they would've dug underground if the folks living there weren't also mining. Probably not. I haven't heard of other deserts with underground homes.
