Most people believe that fictional characters are just drawings on paper, graphics on screens, etc. That is mostly true, but there is a part of the fictional beings that no human knows. In a distant dimension, exists a place where all imagination becomes reality.
   This dimension did not always exist. When ancient peoples told stories, made drawings, and other things, those ideas did not have a place to go to for realization. But many many years later, sometime in the 1800s, something occurred which is known as the Great Creativity Boom. It is when Cartoons and comics and fiction series and so on and so forth became popular and mass produced. Many people started using their imaginations, and started creating the countless stories, shows, movies, and games we have today. Gradually this stream of imagination became bigger and bigger. The amount or energy being given off by the creators was so great that it began to mix, and culminate, and blend into a physical, yet imperceptible, essence. The ideas became so numerous that the huge ball of energy exploded in a "Big Bang" fashion. This caused a disturbance in the cosmos. If the ideas continued to get larger, they would engulf the Earth and cause it to implode. And the humans would never know it was coming. Fortunately, life had already begun in this little Imagination Dimension. These beings were some of the leading figures of early cartoons. One of them being Mickey Mouse. He transformed in Wizard Mickey and gathered up all of the magic he possibly could. Which was a lot since he was in the fictional dimension. And with one flick of his wand he sent the cluster of ideas hurdling into outer space, where it could continue to grow without harming anyone, or anything. Mickey and his friends, celebrated their birth into reality, and began to mold it into a home. They called it Imageariah (ee-mah-gear-ee-ah).
   Now, this dimension is divided into two sub-dimensions which are like hemispheres divided by an ocean of space. There is a western hemisphere and an eastern hemisphere. The founding fathers of Imageariah did this to honor the diversity of fiction in western cultures apart from those of eastern cultures. The Western Hemisphere is known as Carstrewsa. The Eastern Hemisphere called Easternimangako.
   Mickey Mouse became close friends with another Imagearian named Doraemon. They researched the fictional world by returning to Earth and finding as many sources of information that they could find and take them back to Imageariah. During their visit, Mickey Mouse stumbled upon the house of Walt Disney. He learned that this man was his creator from the research he had done. Curiosity overtook the poor mouse, distracting him from his tasks. Mickey Mouse revealed himself to Walt Disney. Of course Disney was frightened at first. But his imagination was already wild from all of the works he had done. He quickly found the humor in the situation. He found the real Mickey Mouse to be fascinating. They talked. Walt Disney told Mickey Mouse stories of his creation. And Mickey Mouse explained the story of Imageariah. They talked for hours on end. Then Walt Disney decided to help Mickey dig for information about fictional characters all over the world. They even searched for new ones who had been created after the Great Creativity Boom. With Walt's help the operation went very smoothly, as he was able to contact other artists from around the world whom he had met throughout his life. Mickey Mouse was so grateful to Walt Disney that Mickey Mouse used his magic to create a special ring that would allow Walt Disney to visit, and leave Imagearah as he wished. Walt Disney helped to construct Imagearah and came back with many new ideas in his head that he passed down to his family, friends, and colleagues.
   Now Imagearah's Sub-dimensions, Carstrewsa and Easternimangako crossover every once in a while. Mickey Mouse and Doraemon came planned this so that they would have a chance to reunite and discuss things that are happening throughout the whole dimension. When this happens the story realms (area of the sub-dimensions where groups of characters from one franchise reside. Kind of like a country) overlap and new stories play out. These are largely influenced by the recent rise in fanfiction stories/crossovers. The entire dimension of Imagearah is shaped by the imaginations of human beings.
   And this dimension will exist eternally, even after humans are gone. Perhaps the same thing will happen to the Imagearians, and a whole new dimension will be created. But for now, Imagearah is the realm where all of your dreams come true.
