Null Box

Occasionly vital for preserving or safely containing a sample or woeful artefact, null boxes are portable statis field generators in the shape of small armoured boxes, although some go right up to the size of a large chest or sarcophagus. Inside a Statis Field, all time and motion halts and whatever is trapped inside is effectivly frozen and removed from any interaction with reality -- essentialy contained in a psychic dead zone. True relics of the Dark Age of Technology, most null boxes are extraordinary resilient and tough (almost supernaturally so, which may be the resuly of the time-control field within) and once active require no further power unless deactivated and turned on again. For obvious reasons the control mechanisms of most null boxes are often hidden and heavily encryted. Unless breached with enormous force or simply turned off by someone able to do so, a null box its contents can out-sit eternity if needs be.
