Dismissing the ruined sash from her mind, Hart surveyed the chamber, It was large, a vast womb in the belly of the earth. The ceiling was hidden, even from her eyes, in darkness and haze. Lights mounted on the exposed girders of the structure cast sharply defined cones of light onto the floor. Hart stood on the highest level, a platform with twin ramps leading down in opposite directions. She could just barely discern other platforms hugging the walls at various levels below her. The chamber formed a great bowl, each level spiraling toward the crowded floor of this carefully guarded sanctum.
