Marcus

This story is something that has been in my mind for a very long time. What if Imagination was something you could control. In this story, Marcus, the main character is specifically put in charge of the Realm of Imagination where he has created beings along with many other creatures that other humans have made in their minds. However, Marcus does something terribly wrong. He creates a being with the same abilities as him. He wanted an apprentice, but that apprentice went rogue and destroyed the earth along with a devastating amount of humans.
