Adrian was originally an ordinary swordsmith in the City of Ashes, but he awakened the cursed Shadowborn bloodline on his twentieth birthday. He discovered that his birth was actually a "doomsday plan" jointly planned by the forces of light and darkness - by fusing the power of angels and demons, he created weapons that could tear apart the barriers of the world. In order to escape his fate, Adrian embarks on a journey to find the truth, but along the way he encounters a mysterious black-robed prophet, a demon lord disguised as a human, and a Holy See inquisitor who intends to purify the Shadowborn. As he gradually uncovers the true origin of the "Eternal Night Era", he must make a choice between destruction and redemption: to become the creator god of the new world, or to end all wars with his own death?
