Comprising the nerve center of the Time Variance Authority, the Chronomonitors are housed in the Hall of Chronometry, an infinitely large space filled with desks and monitors each manned by a Chronomonitor. The Chronomonitors are each assigned a specific timeline to monitor and direct. When a signal event occurs within a timeline, the observing Chronomonitor calculates the importance and, if warranted, splits the timeline at that point to follow the various probable consequences of the event. Additionally, each time a universe is bifurcated a new Chronomonitor is created to supervise it.[1]
