When W J and H drilled through the surface of Mars and discovered a colony of humanlike creatures everything changed. Although the newfound race was unaware of the findings the flow-on effect was undeniable. Within weeks our own crust was penetrated and another similar group was unearthed. Once a reliable communication system had been establish the truth was openly revealed: Planet Earth was actually an artificial shield. The surface had only been created to protect the colony from invading forces. The people of Neptune started the trend after an attack from the close rivals of Uranus. They created a freezing, seemingly impenetrable fortification to protect their colony. Earth later followed suit; they developed a fort on which protecting citizens could provide added defence. This security later proved counterproductive. The Martians discovered the hole in their protective crust and considered it an attack. Their response resulted in the complete destruction of Earth.
