Saevenia's universe has unstable physical laws which result in it being quite different to our own. It is roughly 500 billion years old, light travel is instantaneous, celestial bodies are more static, and magic is possible. The universe isn't moving further apart like our one is. One character says of our universe: "This one is stretching out and moving away from itself, resulting in a lot of... Well, space. It is violent and isn't aging well, how unfortunate for its lifeforms. The more intelligent among them should get out while they still can."
