As all people know, there are three parts of an existence. The three parts are the body, heart, and soul. First is the body, which acts as a vessel for the heart and soul. It gives a person a physical appearance and form. It acts as a medium for the heart's feelings to be expressed to the world.
Second is the heart. It is one of the most key elements in being a complete being. Many have tried to explain what a heart is made of, though they have all failed. It seems, though, that the heart, like everything else, is made up of both light and darkness. It holds many of a person's emotions, both good and bad. It is said that hearts all the source of all power, and indeed, it does seem that a lot of influence is based on the heart. Hearts that yield to the darkness are turned into Heartless, though I will explain that later.
And lastly is the soul. It gives the body life and gives it the will to live and drives it to survive. If the soul separates from the body, the body gives away to death. However, if the heart is taken away and the person, be they evil or good, has a strong heart or will, continues as a Nobody. Like the Heartless, I will explain the Nobodies later in the chapter.
Now, Heartless are beings made of darkness. They are made when a person yields to the darkness. They have only one purpose, and that is to gain even more hearts. They seek out the hearts of worlds and, finally, Kingdom Hearts. Kingdom Hearts is the heart of all worlds, and contains an immeasurable amount of power and wisdom. Many wicked characters seek out Kingdom Hearts for their own purposes.
However, there is another type of enemy. They are called Nobodies, for they do not even exist. They are creatures without hearts, so they cannot feel any emotion. But there is one type of Nobody that is very dangerous. They are born when a person with a very strong heart and will become a Heartless. The resulting Nobody looks like a human, with a few minor alterations. What makes them special is that they can remember what is like having emotions, and thus can act like they have emotions. They too are looking for Kingdom Hearts, although for a different purpose. They want Kingdom Hearts to become "whole" again. They had formed a group called Organization XIII, but a boy named Sora defeated them…
Now as I have told you there are three parts to a being. But unbeknownst by some, there is actually a forth factor: memories. It is very special to the heart, for if the memories of a person collapse, so does the heart. Memories are eternal, and while they can be concealed or forgotten, they can never truly fade away. They are the thing supports a Nobody's fragile existence, and without it they would fade into Nothingness.
But what if a person willingly gives up his heart and his memory? Would they still survive, or would they be pulled into the endless abyss of Nothingness? This can be answered in this story of a boy who gave up on hope, but yet still lived on, a person, who gave up happiness and hope, only to be filled up by emptiness, a person, who questions everything he believes in. This is the story of Cannox, the Tormentor Obliterator.
