box. It was a shattered ruin. Once the fact was clear, she composed herself and lay there, breathing hard and thinking. She had no means to construct another key. At best, finding the rare tools and parts would take months, and during the interval the invaders would be cutting loose from the dead hulk that clutched their conquering battle globe in a metallic rigor mortis. She gave herself six weeks to accomplish this stalemate in space. Within that time she must know whether the prime movers were still intact, and whether she could safely enter the pile room herself, set the movers in motion, and draw the moderator columns. If it were unsafe, she must secure the unwitting assistance of her Scythian enemies. Still prone, she found the first-aid kit and taped her chest expertly.
