Fantasy

Humanity collapsed in a single night.
    When the sky darkened and a perpetual night arrived, even the strongest monsters turned feral, tearing through cities until nothing was left but ruin.
    Dying alone in the ruined world, Ryn Eden Arctis finally understood the truth.
    Years ago, he was given a strange skillbook—one the church labeled taboo, one no one dared to touch. But the world had taken it away from him.
    However, he knew that—whatever was inside it, had to be powerful enough for him to stop this calamity.
    His final regret echoed through the silent wasteland:
    “If I had learned that damn book, we’d still be alive.”
    With his dying breath, he wished for only one thing:
    To go back in time and claim that forbidden power, no matter what.
    A single star answered.
    Ryn opens his eyes ten years earlier, on the day he received his first skill.
    WHAT TO EXPECT:
    - Korean Regressor Fantasy, if you like that genre this might be the one for you. Think (Trash of the Count's Family, Swordmaster's Youngest Son, FFF-Class Trash Hero)
    - Romance subplot is prevalent. This is not a harem novel!
    - MC is NOT naive, and will NOT be afraid to make morally gray choices! Readers advised!
