The Athos belt is a vast asteroid field comprising over 2 million asteroids, each with a diameter larger than 1 kilometer, orbiting Astra Nova in a little over 4 years. This region is notably abundant in Actium, and scientists speculate that the Athos belt originated from a colossal collision between Anemo/Ventus and a massive rocky element, forming an extensive debris field.
