The Distortion Field is a Sacon-built and engineered piece of technology. The Ascended was one of the main engineers in the project.
Breaking the Contract of Sangrae La, with the Distortion Field now in effect, does not carry much of a sentence. In the time of only the cloak of Gorok’s shields and Empirian vigilance, trespassing was usually met with execution, but that era was short-lived as the Distortion Field removed the need for such action. There are some Empirian officials that still enjoy imprisoning or slaying law-breakers, but the point of enforcement is now mainly to prevent Human contact rather than to punish Empirians who go to Earth.
