The Hollow Planes, opposite to its name, is actually filled with wildlife and nature of all-sorts. It is where magic users reside.
The Hollow Planes appears as a nature/wild life-filled dimension. There are several structures that take the form of floating islands or even entire palaces.
A mysterious dimension that is filled with mana. Often, the mana overflows different dimensions, causing rifts in between worlds, resulting in people seeing mysterious islands/beings/places such as Mu or Atlantis or Lemuria or even Avalon. Powerful enough magic users can access this dimension through a ritual, though only a few have succeeded, the rest have perished. In most cases, magic users are invited into the dimension by its ruler. Due to unwanted intruders entering the realm at random times, the ruler has sealed off a deal with a legion of Eldritch creatures who will guard the place as long as he is alive, while also providing the creatures with their needs.
