Ar Ciel

This is the planet that is used as the setting for all of Ar tonelico and its related works.

It seems to be mostly similar to Earth, though with various differences, the main one being that it has two moons instead of one. Said moons are called the Viola Moon and the Cello Moon.

However, 700 years ago, because of the Grathnode Inferia disaster, the surface was covered by the Sea of Death, and the sky was sealed off by the plasma sea called the Blastline, so now, the only inhabitable areas are the floating lands located near each one of the three Towers of Ar tonelico.

At the present, there are only three regions known in this planet, which are the places where each one of the three Towers were built:


 * [[Sol Ciel]
 * Metafalss
 * Sol Cluster
