Famous writers throughout history find themselves being reincarnated by a mysterious, unseen entity known as the Alchemist.

Along the way, they must also rescue and recruit fellow authors trapped within the very stories they themselves had written. Although the writers take on new and powerful forms for this endeavor, some still maintain a semblance of who they once were, while others struggle to remember their pasts and the works they had penned. Despite there being no apparent end to their grand mission, they remain committed to the cause in hope of resolving the mystery behind their collective resurrection as well as questions that have haunted their former lives.
