The Reincarnated Author
Godfrey Milton, a successful Author who managed to make it as a New York times best seller, self accomplished and single bachelor. He feels a certain accomplishment in his life but as of late, he's hit a block. A writer's Block.
He struggles to force his way out of it but fails miserably. Until he found a certain book. His very first book "Shadows of Self". The only book he had never completed.
Feeling a bit nostalgic Godfrey decides to read Shadows of Self for old times sake, he falls asleep and suddenly wakes up in the abyss. His soul had been ripped from his body and thrown into the very book he had written.
The book that had no ending.
Fortunately he was blessed with a system, the same system that gave him a single mission. To find a conclusive end to the plot.
Godfrey reincarnates into the body of the support side character, Frey Greystone. Now with the help of the system, he must find a way to end the story in a way that either pleases the system or pleases himself.
Or so he thought, but the system had other plans for him, other worlds he must save, timelines to restore, worlds to build. But Frey years for his freedom more than anything. Would he get back his freedom or become the God Of Stories?
