Book of Otherworlds

Many people believe that our universe and world are unique, but this is not the case. In the macroscopic universe, the world is composed of many different dimensions. Outside of the real dimension, there are worlds in many other dimensions. Each world has completely different rules and structures. The worlds are separated by the wall of time and space, so that there will be no intersection between worlds in different dimensions under different laws. However, using a magical spell called summoning, people summon creatures from other dimensions into the real world. People with such power and knowledge are called summoners. The Book of Other Worlds is the carrier that records the knowledge of summoning. Please be careful with what you see next, as it may take you into a world beyond your imagination.
