Force field

A force field, sometimes energy field, seemed to be a very broad, general term for any type of field, most commonly artificial, in which matter or energy was manipulated through some type of force.

Artificial force fields tended to be projected from a single device, and thus normally had a certain radius over which their effect gradually weakened to negligible. Energy from most force fields could also be concentrated into a plane, a "skin" around an object, a beam, or even a single point, though this often required more advanced technology. Force fields could be disrupted through outside interference occasionally, such as with the use of a power gem.
