Imagine a world where the sun has vanished, swallowed by an angry sky. Humanity's reign ended not with a whimper, but a bang, transforming the world into a nightmare realm ruled by frenzied beasts. In this desolate landscape, we find Ryn Eden Arctis, drawing his final breath, a horrifying truth piercing his mind. Froyers' *Forbidden Constellation's Blade* unveils a world teetering on the brink. Years ago, a forbidden skillbook, deemed heretical and dangerous, fell into Ryn's hands. He rejected it then, but now, amidst the apocalypse, he understands its potential. It was the key, the power he foolishly dismissed, that could have saved them all. With his last ounce of strength, Ryn wishes for a second chance. An ancient, celestial being hears his desperate plea. Ryn awakens a decade in the past, reborn on the day he first received his skills. Haunted by the memories of a ruined future, he's determined to embrace the forbidden power, regardless of the sacrifices required. Fans of Korean-style regressor fantasies like *Trash of the Count's Family* and *Swordmaster's Youngest Son* will find themselves captivated by this tale of second chances and morally gray choices. Expect a compelling journey with a strong romance subplot, but without the trappings of a harem. Ryn is no saint; he's a survivor willing to walk the line between good and evil. Can he alter the course of destiny, or is the apocalypse an unavoidable fate? Read *Forbidden Constellation's Blade* and prepare to be enthralled.
