The Nobody opened the steel door and walked out into the chilly air of the dark world. From being atop the roof of one of the buildings, he could see the base along the never-ending horizon of buildings. Quite a distance away, Demyx could see the memory skyscraper, the end result of hearts returning to darkness, being used to create Kingdom Hearts.
He sometimes questioned how the darkness shaped itself into a vast modern city complete with random lit-up windows and even a vehicle or two. There were no residents within these buildings however. The area reeked of the stench of heartless, even though they did not reveal themselves to he or the rest of the Organization.
Demyx closed the door and sat in front of it. With the Memory Skyscraper and Kingdom Hearts side by side directly in his view, it was a beautiful place to play his music. He raised his hand out and summoned his guitar.
He began to play. Demyx knew a wide variety of music, but he would always end up stringing the same tune. It was one he had made up right after he joined the Organization.
He would pluck the strings softly, but with speed. He was going to call it "Desire for All that is Lost," but decided not to name it at all.
The Memory Skyscraper reacted to his remembrance of the tune. Demyx expected it. He decided to just sit back and watch the giant screens of the building while playing.
The "film" began with him coming into the existence he was in now within Dawn Valley. It was a good world with good people living in it. He was lonely even though he ended up being cared for by a kind family who clothed him and everything.
The mother and father had a son, who was getting quite interested into music and would ask Demyx (he had no name then) to play the guitar that was somehow linked to his very being. Being a traveling musician surely did have its benefits.
The boy eventually bought his own guitar and both of them played music, but Demyx would always play the same music. He once said in his past life as Myde that all of his music reflected his heart. Consequently, that same detail was kept; he later found out from Saix, who had come to recruit him, that he had no heart, thus explaining the emptiness of his feelings and music.
As a human, he wouldn't have approved of dreary music. Everything had to have emotion. This passion led to the present state of Myde's heart, somewhere within the dark city.
The music he played didn't have an end to it.

I decided to change his name.
I hated doing this. Demyx was hard as hell for me. I think this is too short.
