Black Chair

At first glance, it appears to be an ordinary chair. It comprises simple, inexpensive wood. However, there is something special about this chair. When combined with the homicidal A.I (Trinity) and an impossible object, it allows the users (The Marshalls) to see into the lives of people. Through these glimpses, the Marshalls must determine the right moment to intervene and change events before the promised doomsday arrives.
