Reborn into a House of Knights, I Secretly Revive the Magic That This World Abandoned

Not my enemies. Not the world. My own disciples. My own people. They drove a spear through my heart the moment I touched the threshold of true understanding. Three hundred years of research. Lifetimes of sacrifice. All buried in a single act of betrayal. But I didn't disappear. I woke up somewhere else. A different world. A different time. In this place, magic is treated like a forgotten relic. Knights dominate the land. The Church speaks of divine blessing as the only true power. And mages? They're dying out—weak, corrupted, barely worthy of the name.
