As I've been developing my stories, one major point that has remained constant is the state of the major international powers. One such powerful nation, sahats, is an extremely advanced society. They have incredible medical abilities, and they are currently the most advanced nation when it comes to science. They use graphene and magnesium in place of other materials, and they use incredibly efficient production methods.
However, they tend to spend their time, just existing. they don't throw their military around, in fact, they don't really get involved at all in politics unless they have to.
They typically build their cities in the forests of the world, making their lives among the massive trees. They build their houses, stores, and everything else inside hollows in the tree, modifying them however they life without harming the trees.
Is a society like this possible? they aren't humans, so they might behave or think the same way, but I'm not sure if that helps. If it is possible, then how would it happen?
