Phantom Planet

Landscape of the Phantom Planet.

The Phantom Planet is an unnamed planet from which the Phantoms in the movie Final Fantasy: The Spirits Within originated.

Similar in nature to Earth, the planet had its own spirit and supported a variety of life forms. Unfortunately one of the prominent species of the planet became embroiled in a cataclysmic civil war that resulted in the destruction of the planet's environment and ultimately caused the destruction of the planet itself.

While the entire planet was destroyed, a fragment of the planet was flung across space; becoming a meteor that crash lands on Earth and starts the Phantom invasion that devastates the other planet's living population.
