The Plane

The Plane, simply known as Earth (or equivalents in other languages) by locals, is a universe completely separate from the Expanse, the universe that both Tsinko and the Five Worlds exist in. It is notable for being a single, continuous plane that sits stationary within its universe. Magic in the Plane works differently from the Expanse in that while magic is known, and widely accepted, it is nonetheless exclusive to a specific group of people known as Tamers, which are those who have the capability of taming and controlling ghosts (typically poltergeists or phantoms).

Celestial Objects
Celestial objects, such as the moon, sun and stars, are not actually objects. They are merely things that exist in the sky, and no matter how far or fast you travel, you will never reach them. They are not, however, projections. They have no source, and are thus not projections. They are, as mentioned before, simply things that exist in the sky.
