The Alicorn Kingdom is a wondrous and mysterious realm; true to its name, every single resident living here is an alicorn.
It exists within an isolated dimension, completely disconnected from other worlds. Only occasionally do spacetime rifts temporarily link it to other realms, and it is through these rifts that the alicorns learn of the existence of other worlds.
To put it simply, the relationship between Equestria and the Alicorn Kingdom is much like the relationship between Asgard and Earth in the Marvel movies, except the two worlds are entirely separate.
