Celestial Realm

The Celestial Realm is the homeland of the Goddess Clan.

History
According to the Lady of the Lake, the Celestial Realm was created along with the Goddess Clan by the Supreme Deity, after she was given birth by Chaos.

We know almost nothing of the Celestial Realm, except that it was essentially composed of "Sky Palaces" connected to the rest of Britannia by portals generally located in the altars of the Druids, or the Light of Grace.

Trivia

 * The Celestial Realm is likely based off the concept of Heaven from monotheistic religions and others such as the Elysium Fields from ancient Greek mythology.
