The Underway

The Underway is a vast network of interconnected tunnels, subway railways, and municipal facilities hidden beneath the streets of New York City. Serving as a secretive passage for Sewer Samurai, it allows denizens of the sewers to move undetected throughout the city. Despite attempts by various factions to control sections of the Underway, its sheer size and complexity make it impossible to fully block off. Sewer Samurai navigate its labyrinthine paths, disappearing seemingly into thin air as they traverse its hidden routes to reach their destinations.
