A man wakes up in the worst possible isekai scenario: not as a hero, not as a mage, but as a sewer rat beneath Waterdeep. Armed with human memory, gamer instincts, and a single, bizarre inventory slot that can hold one item of any size, Jim—now “Rat #1”—has to survive boots, cats, alchemical waste, and the brutal food chain of the undercity. As rival factions stir below—wererats consolidating power, nobles unaware of cracks in their foundations, and strange magical runoff in the tunnels—Jim is pulled into a growing sewer ecosystem of gangs, protection rackets, and whispered loyalties. He isn’t strong. He isn’t big. But he can listen, plan, and carry things no rat should be able to carry. In a city built on layers of stone and secrets, Rat #1 begins at the bottom—quietly, stubbornly, and very inconveniently rewriting who counts as prey.
