In a world consumed by despair, Alaric, a derided Essence Sage, helplessly watches as the Demon Lord annihilates his homeland of Eryndor, leaving him the last survivor amid a battlefield of fallen heroes. With no options left, he activates his long-dismissed class skills, Essence Extraction and Essence Infusion, harvesting the fragments of power and memories from fallen soldiers. In his final moments, Alaric creates a forbidden hybrid skill—Essence Regression, sacrificing his soul and the collected essences to send himself twenty years into the past. Awakening in his younger self, armed with the haunting memories of failure and the echoes of warriors’ lives, he vows to master his class, unite the scattered powers of the past, and alter the fate of his doomed nation.
