I used to be the greatest Earth Mage in my world. The head of the entire Order of Architects. But the older you get, the more you come to realize that at some point, you need to retire, so that you can have the chance to enjoy a peaceful life and to cede your place to the young, some of whom have already turned two thousand years old . . .So that's what I did.

And I hope their deaths were final. But mine was not!

I was a Hunter, and I honored the Code. For my services to humanity and for leading a "proper" life, I was to be rewarded. A new life after death, and a new world to give me some well-deserved rest. But something went wrong. Once again, I must fight. The Monsters that face me here are far more terrifying than those of my past life. They are cleverer, crueler, more unpredictable. And their name is.
