Mount Celestia

The Seven Heavens of Mount Celestia is an outer plane dominated by a massive mountain with seven plateaus at varying heights. The realm is the model of justice and order, though it is tempered by mercy and compassion. Here, the paladins and champions of good guard against incursions of evil into other upper planes. The various seven plateaus represent ascendingly sublime existences, and many souls strive to reach as high as possible - but few ever reach the top. In this plane, with its celestial guardians and host of Good champions, travelers can let their guards down and simply enjoy the sights.

For more information on this plane, such as the names of its seven layers, consult the 5th Edition Dungeon Master's Guide, page 59, and check out the Forgotten Realms wiki: here.

Pureheart

On the second layer of Mount Celestia, called Mercuria, lives the Deirid Eamon and his host of lawkeepers and guardians. Like the rest of this particular plateau, Eamon's palace is suffused with a soft golden eye that makes even common burlap appear to be woven of solid gold thread. From this palace, called Pureheart, Eamon holds court and answers the questions of those who come to seek his guidance.

The Muster

On the fifth level of Mount Celestia, known as Mertion, one can find the Deirid Múr, the Shieldbearer, and his massive host of paladins and solers. Múr lives in a fortified castle called simply The Muster, as outside this castle is where the hosts of Mount Celestia gather before departing to their duties on other planes. Between musters, Múr has been known to host glorious tournaments that draw contestants from as far away as Ysgard.
