The sudden split up and the realization that they had all been small minded left many confused. They had no idea how they had missed so much. But they had never experienced more. They had only been limited because of their own minds and the state of the world.
It wasn't that everyone wanted space because they could not think well enough unless they were alone. It was more so that they weren't sure how to handle this.
Being told that you had always known the world to be complete and suddenly being told it wasn't, were very different things.
The changes that this could bring on top of the massive amount of growth already, were staggering. If the next generation could be born with a lot of open and free paths, it could mean that all races were more equal.
Creation is hard, cheer me up!
