A divine curse marked Arzael from birth, claiming his mother's life as his price. The imperial family rejected him, treating the cursed boy as nothing but filth to be despised and tormented. Hope was never an option. At fifteen, he was thrown into the Underworld's bottomless layers—a demon-infested hell where the damned rot eternally. Shattered and dying, Arzael experienced a moment of salvation: a mysterious system emerged from his anguish, converting his suffering into raw power. His pain fuels his strength. His blood accelerates his ascent. His torment propels his evolution. Arzael returns to the surface transformed. The cursed child no longer exists. He has become something infinitely more terrifying—a force of retribution for all who cast him down.
