The Eye of Atamoni is a result of the large, Lens-infused comet that collided with the planet some 1,000 years prior to the events of the story. As the sky enveloped with dust clouds that shielded the planet from the sun and plunged it into a devastating ice age, humans learned to use the power of Lens to construct a massive floating continent known as the Aethersphere, which hovered above the Er'ther Lands. The upper class of people who migrated to the Aethersphere eventually became known as the Aeth'er race, while the population left behind came to be known as the Er'ther race.
