This is only a fanfic, so it will differ slightly from the original.
Merlin, the most powerful wizard of legend, had reached a pivotal moment in his journey—he was on the verge of attaining godhood. However, during a battle with a divine being, something went terribly wrong. He was somehow trapped in a void of absolute emptiness. Within this void, his soul was shattered, leaving him incapable of escaping on his own. Tortured endlessly and unable to die, Merlin endured unimaginable suffering.
In his desperation, he made a fateful decision: to merge his soul with another and sacrifice himself in the process.
Meanwhile, in another world, a young boy lay confined to a hospital bed, his life consumed by despair. At the moment of his death, his soul was unexpectedly summoned by Merlin into the world of Harry Potter.
Through the merging of souls, the boy was reborn in the magical world—now carrying the legacy, talents, and unfathomable power of Merlin himself. Given a second chance at life, he began a new journey.
In a world where divine beings subtly manipulate events and struggle for control, our protagonist—unbound by fate—will attend Hogwarts. There, he will face not only Lord Voldemort but also the mighty forces of the divine.
