The Archway is the field office of the Time Riders. It is in New York, looping around the same two days (Monday the 10th of September 2001 and Tuesday the 11th of September 2001) forever. The days are chosen because they are the day before the Twin Towers are destroyed, and the day it does, meaning that no one will remember them due to being preoccupied with the 9/11 attacks. The timeriders are there until The City Of Shadows, when they move to Victorian England with their new member Rashim.
