Some are invisible, some are made of energy, some are pulled up from the earth. Many powers allow users to generate Force-fields. They may be nearly any shape or size and may be created from nearly any item including Air Currents. Many Magic users create force-fields to protect themselves from incoming attack. Force-fields are not impenetrable usually requiring an energy drain or extreme weight to be broken. Some users may be able to throw shields away from themselves or to catch things with them. Other users may be able to mold them into any shape.
