For as long as I can remember, there was nothing. I didn't mind mind, because it was all I had ever nothing. There was just me, surrounded by a dark void, thinking.

Before time existed, there was a being. It had no body, but was alive. When the Universe exploded into existence, it realised that it could move the individual atoms to create and destroy entore galaxies. This is the story of a god.

When god gets bored, he creates deities to amuse him. He makes a planet and fills it with life, including people, and give them a challenge. The deities have 10000 years to make the people as advanced as possible, or they die. Oh, and there's magic.
