PhantomRealms

There was once a black wizard, known as the King of Monsters. He was the leader of the Calamities, and creator of Ouroboros the World-Eater. After the Second Holy War, his soul was split into pieces. Every fragment but one was destroyed. The remaining fragment, known as the Seed of Chaos, was caged inside the Celestial Realm and guarded by the Elder Dragon Amaru. On the day that the stars aligned, however, two things happened at the same time: the death of a truly emotionless child on Earth and the fate-changing spell of a black wizard who was well versed in the magic of Fate. 
These two events lead to the disappearance of the Seed and the emergence of a black slime that would either lead the world to ruin, as was its purpose, or create a new age filled with the knowledge of Earth.
