Rigel Black and the Echoes of Eternity

Rigel Black, a name whispered with both reverence and disdain, finds himself marooned in a parallel echo of the Wizarding World, one where the Potter era is a forgotten myth and magic has twisted into something ancient and feral. At 80 years old, his 'cheat' is not raw power, but an unparalleled mastery of temporal manipulation, allowing him to subtly rewrite moments, perceive future echoes, and rewind personal failures. Yet, this fractured reality is collapsing, devoured by a parasitic entity feeding on ley lines. Rigel’s core conflict ignites when he realizes this world's decay mirrors a hidden blight in his own timeline, a blight his temporal powers cannot directly touch. He must navigate a decaying Hogwarts, form alliances with wizened, forgotten figures, and confront the unsettling truth that saving this world might damn his own.
