The EverRealm is a parallel world that is magical in nature, and contains medieval/fantasy elements as a part of its culture. It is the world in which Sofia the First and Elena of Avalor take place.
The EverRealm is a fairy tale-like realm. While similar to our planet Earth, its key characteristic is that magic constitutes a major role in the structure of the EverRealm's civilizations and wildlife. The source of all the magic in the EverRealm comes from the Mystic Isles. Most of the cultures of the EverRealm are kingdoms governed by a monarchy. In addition, some kingdoms occupy the same area (such as the Tri-Kingdom Area between Enchancia, Khaldoun and Wei-Ling) and have formed strong ties to the point that there, are social festivities for celebrating the kingdoms' relations.
One of the realm's earliest civilizations included Maru, whose people practiced some of the most powerful forms of magic in the EverRealm. They were also responsible for creating magical artifacts such as the Amulet of Avalor, the Scepter of Light, and the Codex Maru. One day, Maru vanished without a trace, and the Kingdom of Avalor rose in its place.
According to Admiral Hornpipe, there are seventeen seas.
Wildwing Valley - A forest valley that is a haven for enchanted beasts like flying horses.
The EverRealm is slated to have 140 kingdoms. However, according to Princess Hildegard, there are 138 kingdoms.
At the time of Hildegard's statement, the kingdoms of Hakalo and Merroway Cove were considered legends.
The EverRealm is moving at the same time as the real world, despite the medieval infrastructure.
The EverRealm is home to, or visited by, several of Disney characters, most strikingly Merlin and Flora, Fauna, and Merryweather, magic-users depicted in Sofia the First as inhabitants of the EverRealm, yet who were able to visit England in various time periods in the Disney classics. It is unclear if they are alternative versions, or if they had crossoed over from the EverRealm to Earth in the Disney feature films.
In the case of the Disney Princesses, most of the ones summoned by the Amulet were EverRealm denizens from different decades. However, only those from fictional settings are from the EverRealm; those who come from a specific real-life place (i.e. Tiana from New Orleans) are not. This is supported by Cinderella's statement that the Amulet can summon "all princesses that ever lived", and is not necessarily limited to those in the EverRealm. The statement that "all the Princesses from made-up kingdoms" are from the EverRealm does, however, clash with the Earth-date of 1840 being given in Frozen Fever despite Arendelle being an imaginary kingdom.
EverRealm is a nod to the phrase "Happily Ever After".
The close captions keep alternating the spelling between including and omitting the space between "EverRealm" and "Ever Realm".
