The series is set in the near future, where aliens known collectively as Votans have come to Earth seeking a new home after their solar system was destroyed. However, when they reached Earth, they discovered despite a prolonged negotiation with the government on Earth, they were not welcome. Rather than turn away, they began a war with the humans as they are determined to make Earth their new home. During the war, the Votans dropped terraformers on the planet and transformed the surface; scorching the earth, opening chasms in the ground and covering the surface of the planet in dust and debris. After decades of war, a ceasefire is declared when both sides realise they must focus on survival on this new almost alien planet.
