The Book of Another World

Many people believe that our universe and world are unique, but the truth is otherwise. On a cosmic scale, worlds are made up of many different dimensions. Beyond the dimension we call reality, countless other worlds exist.

Every world has entirely different rules and structures. Walls of space and time separate them, preventing worlds governed by different laws and dimensions from intersecting.

However, through a wondrous magic known as summoning, people can summon creatures from other dimensions into the real world.

Those with such power and knowledge are called summoners.

The Book of Otherworlds is the vessel that records the knowledge of summoning.

Be careful as you face what you are about to see, for it may lead you into a world beyond your imagination.
