When a mysterious time traveler threatens the fabric of reality, Batman finds himself catapulted from the familiar streets of Gotham into Victorian London. Teaming up with the legendary Sherlock Holmes, the Dark Knight embarks on a mind-bending adventure that spans centuries and realities. As the stakes escalate from a simple case of temporal displacement to a crisis that threatens the entire multiverse, Batman must confront alternate versions of himself, cosmic entities, and the very nature of existence. Along the way, Batman and Holmes are aided by Pennyworth and Watson, and together they assemble a team of inter-dimensional allies, including Wonder Woman, Superman, and multiple incarnations of Batman himself from across the multiverse. The journey takes our heroes from the fog-shrouded alleys of 19th-century London to the far reaches of space and time. They face off against a corrupted future Batman, the enigmatic entity known as Omega, and the chaotic forces of a collapsing multiverse. Each chapter unveils new mysteries, escalates the cosmic stakes, and challenges Batman's understanding of his role as a protector. As reality itself begins to unravel, Sherlock Holmes, Batman and their allies must rewrite the rules of the multiverse, establishing a new cosmic order that balances infinite possibilities with the need for stability.
