The New Final Villain

When a novel author mysteriously finds himself transported into the universe he created, what should have been a dream turns into a living nightmare. In the body of a secondary villain doomed to an early death, he quickly realizes he is not as in control as he once thought. Fate, ever cruel, imposes an even darker challenge: not only must he survive, but he must also transform into the new final villain, leading the forces of darkness he himself conceived. The first twist comes in the form of a mysterious notification that flashes before his eyes: [NEW NOTIFICATION!] [New objective: Build a group of formidable villains.] [Time: 15 days] [Failure penalty: Death!] Before he can process the situation, another notification appears: [NEW NOTIFICATION!] [New objective: Gain worldwide notoriety as the most feared villain.] [Time: 30 days] [Failure penalty: Death!] Now forced to walk the path of villainy, the author must use his intimate knowledge of the world and characters to subvert the cruel fate he wrote. But can he manipulate the threads of the narrative in his favor, or is he destined to succumb to his own dark plot?
