The world: Presumably in a post-apocalyptic future, Dwellers live in Pods – interconnected domes which make up their cities among vast wastelands. Each Dweller has a Smarteye, a device which allows people to “fraction” and visit virtual-reality worlds known as Realms where they can do whatever they want with just a thought. The Pods are to protect citizens from the Aether – a mysterious thing, presumably natural weather element that is constantly in the sky and can bring storms. What is the Aether and how did it get there? Who knows.
