This small safe can be programmed to send objects back in time to appear in the safe at an earlier point. A Time Safe is described as a permitted paradox under the Laws of Time. The Safe allows an operator to warn himself about an upcoming situation, but it also removes much of the operator's free will to deal with the situation.
