Lord of the Mysteries: From Amon's Avatar to the Old One

This fanfiction features multiple heroines, diverges from canon, grants the protagonist overpowered abilities in the first volume, and returns to a low-sequence path in the second volume to align closely with the original storyline. Klein is portrayed as a friendly ally, and the narrative follows the Fate pathway. Readers comfortable with these premises are welcome to proceed. "Monocle? Hold on—what if I'm actually Kidd! Pointed soft hat? No panic, maybe it's a wizard fanfic! Wait... what does 'Come join the All-Mon referendum' mean? I'm done for—I'm completely surrounded by Amon!" Lister is reincarnated as a split avatar of Amon. He sets out to upend the fates of everyone around him, striving to become the true light in the coming apocalypse and reshape the ending into the future he envisions. "You ask who I am? Since you've asked so earnestly, I'll graciously tell you: I am the Key of Light, the embodiment of endless chaos and destiny incarnate... Oh, and by the way, old man, I just happened to devour your Source Material. You don't mind, do you?"
