Mount Celestia

Mount Celestia is the where most gods reside. Its alignment is Lawful Good.

Description
When most people think of the upper planes, they think of Celestia. While Elysium is the plane of ultimate good, Celestia is the plane of all that is holy. There is no greater monument to goodness in the universe than the glory of Mount Celestia.

Celestia is often envisioned as having seven plateaus. In fact, it has only one plateau, wide as a continent at the base of the mountain, rising upwards ever so slightly and spiraling around the mountain seven times before reaching the top. Pilgrims to Celestia spend many years walking up the mountain, everyone else flies or uses portals.

At the bottom of the mountain lies the Silver Sea, an ocean of holy water that holds more life than the actual mountain. It's an effective deterrent against unholy fiends and undead, who find themselves waist-deep in deadly holy water the instant they step onto the plane.

At nearly every place in Celestia, enormous monuments of one kind or another can be seen in the distance. Structures of all kinds are adorned with sculpture and art, built of the white marble-like rock that the mountain is comprised of.

Celestia is home of the Angels, the universe's champions of good. Devas, planetars, and solars are the most well-known of the angels, but there are many other types, most of them bizarre and terrifying. The angels are immensely powerful but few in number. They prefer to act in secret, nudging events into motion in order to destroy evil wherever it rears its ugly head. Many adventuring parties never discover that they've been guided by an angel in secret.

The 7 layers of Celestia, from bottom to top, are: Lunia (the Silver Heaven), Mercuria (the Golden Heaven), Venya (the Pearly Heaven), Solania (the Crystal Heaven), Mertion (the Platinum Heaven), Jovar (the Glittering Heaven), and Chronias (the Illuminated Heaven). Lunia contains the Silver Sea and the base of the mountain.

Chronias, at the very top, is a beacon of light for the rest of the plane. Nobody knows what Chronias is like, because only the worthiest are permitted entry, and they never return. Anyone else who enters is forever destroyed, body and soul, which occasionally proves to be a useful way of permanently destroying fiends.

Celestia is the home plane of the golden dwarves and ghostwise halflings. It's uncommon for petitioners to be transformed into dwarves or halflings, but it does happen.
