The Sorcerer Epoch

Sorcery: the art of manipulating the elements of the world to produce unnatural effects such as splitting the sea and overturning mountains. After 5000 years of wars against alien races such as Gods, Demons, Cosmic Beasts, and so on, Sorcerers have been able to carve all but a tiny spot in the universe. However, their survival is not all but certain. In the Sorcerer World, August, a 20-year-old man from Earth reincarnates in the body of a rogue Apprentice Sorcerer with a system that grants him the ability to extract 4 different innate affinities. Will he be able to herald the golden age of Sorcerers?
