Mount Celestia

In Dungeons & Dragons, the fantasy role-playing game, Mount Celestia or more fully, the Seven Mounting Heavens of Celestia, or even the Seven Heavens is a lawful good-aligned plane of existence. It is one of a number of alignment-based Outer Planes that form part of the standard Dungeons & Dragons (D&D) cosmology, used in the Planescape, Greyhawk and some editions of the Forgotten Realms campaign settings.
