- Description from Novelupdates

Thousands of years ago, humankind left the Old World. We enter a new age where science and magic are no longer opposing concepts.

With these new opportunities came danger in the form of the Dark Races and the ones that named themselves Gods.

However, if there was one thing humans were good at was their ability to destroy. Humankind fought and carved a bloody path into the new world.

Cain’s luck had never been good, but his destiny changed forever once he decided to harden his heart and face the world without fear or hesitation.
