Void's Heir [LitRPG, WEAK2OPMC]

The Sun is dead, and humanity's new light demands a sacrifice. When the Sun died, Soul Creatures crawled from the darkness. Salvation came in the form of the Soul Devouring Tree—a new light that hungers for more than just shadow. Its price? Every eighteen-year-old must enter the Realm Beyond and face brutal trials to earn their strength and their right to return. Most die. Lune should've been among them. Yet despite his cursed lack, he somehow survives. He awakens as the Heir of the Void—and pays a price not many would be willing to pay. His past? Gone. His present? Erased. His future? Stolen. The world itself forgets he ever existed. But Lune refuses to die in the silence of oblivion. He will not fade forgotten from the very world he's destined to protect. Against the system. Against the heavens. Against fate itself. Even if the gods stand in his way, Lune will carve his name into existence—and make damn sure no one can erase it again.
