Slave Shield

A slave shield is a technology used by the Ur-Quan Kzer-Za on planets inhabited by a race which chose to be a fallow slave after having been defeated, per the Path of Now and Forever doctrine.. Its purpose is to shield the planet from communication with the outside, and prevent anything from entering or leaving the planet's atmosphere. Powerful hyperwave broadcasters are still able to penetrate the shield however, and with sufficiently sophisticated technology it is possible to break a slave shield. A slave shield gives a reddish glow to a planet, when seen from the outside.
