The platform extends further in this direction, and eventually you reach a long set of stairs. It points straight down, makes you a bit dizzy if you stare all the way to the bottom. Keeping your eyes low, you reach the terminus of the stairwell, which opens to the left onto the ground floor. The stairs take you a bit beyond the atrium you were looking down into. You step into the part of the station that stretches all the way through the city block to the other street. It's full of shops: clothing, food, electronics, a post office, a grocery store. For a moment, before you drift into the long corridor, you glance back at the big ornate door that exits to the east. You glimpse a sharp shock of orange poking up through the crowd.
