The Ark Belt is a persistent field of debris surrounding the planet Earth. These are the remains of the Ark fleet that exploded in the Arkfall[1][2] event of 2030. While many of the alien ships crashed to Earth on that day and released their terraforming technology, others remained in orbit, creating a ring of broken ships that surrounds the planet. Occasionally, some of this debris will succumb to the Earth's gravitational pull and fall to the surface. The terminology for fallen arks from Earth's orbit has since been: Arkfalls.
