The Seven Heavens of Mount Celestia, are dedicated to goodness shaped by law and justice tempered with mercy. All aspects of Celestia are beautiful and perfect. As an outer plane, Celestia was spatially infinite and consisted of seven infinite layers (or sub-planes). The seven individual layers formed a colossal mountain that rose from an infinite sea of holy water on the bottommost layer, to the summit on the topmost layer.
The second layer, Mercuria was known as the Golden Heaven because a warm golden light suffused everywhere. This layer contained the armory for the noblest warriors who came here for their eternal rest. If necessary, Mercuria was the marshaling ground for the armies of the Heavens, as well as the gathering place for its troops. It is the location of the divine realms of Amaterasu, Torm, and Girru, as well as the main location of the mobile realm of Bahamut, and most notably, Diche, Goddess of sunlight, also tied to battle and war.
