The underground world underneath the city. . . not literally, of course, it's a subway train, for travel. Day in and day out, people go about their daily schedules as quickly as they can. Some take cars, some take a cab, some even walk, but a majority of people you can count on using the underground train.
Due to its dense population in the daytime, most paranormal don't tend to make themselves known around this area, aside from the occasional misunderstood Visio Dei. No, the chaos in the subways ensue when the day turns into night. Although there are still people going about the subway, they are much smaller in numbers, and that's the time that H.A.V.E.N pays most attention to this location, as every location.
