Earth (OU)

Earth is a planet, and a completely unique one at that. It is only one of two planets in the OU to suffer from the same temporal dysfunction - whenever it is destroyed, a new version of the planet appears to take its place. The Chronicler explains this as being because, at the time of the multiverse's creation relative to Earth's time, the human race had created so much fiction that sixty billion unique versions of Earth took their place in the multiverse at the same time, occupying the same space. Destroy one, and it is replaced by the next from the assortment. Humanity collectively describes this day as "the day the world went mad". The other planet which shares this distinction is Tybion, though the reason why is unknown.

Because of this, Earth has been destroyed several times in large-scale conflicts or terrorist attacks, only to be replaced by more Earths one at a time, each with a unique history. Recently though it has been left mostly ignored by hostile forces, with attention instead being turned to the planets involved in the Uterio War.
