13.8 billion years later.
There was this one unique universe that had only had one planet and the rest of the universe was fill with countless of bright stars. The planet that was in the center of this universe was colassal; it was brimming with life, with different races existing that were scatter around the whole planet. But the only problem was that there was very little water, since 90% of the planet was land and 10% was water. The races had to fight for water not only with each other, but creature that kept appearing and destroying everything. Most creature were mostly undead so they didn't need any food, water or any need to rest.
There were three main races that inhabits the place, the White-eyed Demons, the Colossals , and the Humanoids. There were other races but they were the minority, this three races were the rulers of the planet. The white-eyed Demons are a race with a hierarchy; the white-eyes demons are on top, the rulers, next are the princes of Hell, which are yellow-eyed demons that are generals and commanders, plus there is also the Knights of Hell, demons that are appointed as guards for the white-eyed demons. Finally there is the black-eyed demons that are in the bottom, the commoners and soldiers, etc.
The Colossal race was a race of gaints that were 304.8 meters tall, had a special inherit ability that allowed them to become unseen from the world. To have their physical bodies leave to a special plane of existence that can't be seen by ordinary means. They are small in number that they have become legends and barely few know that they are out there hiding in another plane of existence. Now the humanoid race is a special race in the sense that it is made up of different species that have a humanoid figure, there is discrimination between them beacuse there are mix-bloods that actually in the top, the superior of the humanoid race, the nobles; while the other with no mix-blood are mostly the commoners but there are groups that are equal with the mix-blood humanoids.
Even with all of the fighting going on between each race for water, the Humanoids and White-eyed Demons race civilization were more advance than other races in the planet, not primative but not technological advance either, it's mostly around the middle ages. While the Colossal race just sleeps and hides on mountains ranges or underground. There othere minority of races lives across the planet in the wildlife in small villages and close to the big cities of Humanoids and White-eyed Demons races.
