Earth (or the Earth) is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world, the Blue Planet, or by its Latin name, Terra. The majority of the Road to Hill Nothing story is set on Earth.The Earth itself, was once protected by the Earth Defense Force, untill the deadly virus was unleashed again, causing destruction across the entire globe, and finally lead to the destruction of the EDF shipyards. The entire planet was ravaged by a terrible weapon in 2040 called the G.K.D. (Global Killer Device), which almost lead to the extinction of the entire human race!
Eventually when Dark Origin was defeated, the old order was once again rebuilt and 10 years later Earth managed to recover and the terrible darkness slowly faded away.
The moon station of Outpost IV was located close to Earth.
