William and his entire college cohort are transported to Aethel, a dying world teetering on the edge of destruction. While his classmates awaken to phenomenal magical abilities, William remains powerless—a forgotten outcast deemed worthless among a generation of heroes. Everything changes when William discovers his hidden advantage: an SSS-ranked portal skill granting him access to Aethel's distant past. By studying under ancient masters and reclaiming forgotten magic, he begins to surpass his classmates and unlock his potential as the savior Aethel desperately needs. Yet the perils of past and present threaten everything he's building. Where others merely read about the first mage, William steps back through time to learn from them directly. When his peers dream of dragons, William travels to ancient eras to claim legendary dragon eggs and raise them as companions. As others settle for common materials in their crafting, William harvests resources extinct in modern Aethel by journeying to their origin. The advantage is undeniably unfair—but William refuses to squander the power the universe has granted him.
