It is a planet of almost infinite size, protected by a magical barrier. Countless stars revolve around it in parallel, following the same curved path. Each star has its own rotating magical barrier, with just one small weak point, so its light can only sweep across the surroundings like a flashlight. As a result, everywhere on the planet except its two poles has day and night cycles and temperature zones much like Earth's. For almost all living things, the difference from Earth is that the constellations visible in the night sky change every night. And although the edges of the light cast by the two parallel rings of stars are often as frigid as on Earth, there are no polar days or polar nights.
Aside from the fact that this world has magic, its greatest material difference from Earth is that magic cycles make it possible for matter to cycle through entropy. Besides the matter and energy that return underground as magic cycles across the continents, there are also spells that directly promote the cycles of magic or matter, such as restoration magic, elemental magic, and repair magic. This infinite world is home to a wide variety of living things. The human race may have low limits on its magical power and physical strength, but through intelligence and tools, it has carved out a place for itself.
