*While attempting to rescue SG-10 from a black hole on P3W-451, the Stargate begins to draw power from the black hole itself and cannot be shut down. As the intense gravity field begins warping the space/time continuum and threatens to swallow the entire facility, the Pentagon sends O'Neill's former comrade, Colonel Cromwell, to investigate. Cromwell is tormented by guilt for deserting O'Neill on an earlier mission. As time nearly stands still, Cromwell volunteers to stay behind with O'Neill to save Earth, but he is drawn through the wormhole before an explosion can break the connection and close the gate. *Source: Back of card
