Engines were stopped as they sought a defense against the energy drain which absorbed all forms of energy whether mechanically or biologically produced. Power levels were down twelve percent and steadily decreased. As far as power levels were concerned, everything acted backwards; reverse thrust lurched the ship forward and vice versa, but the drain continued. Analysis of the zone indicated that it was not the source of the power drain. ()
