Diana collapses temple

As soon as they were moving, Diana wedged her shoulder against the wall of the temple.  She thrust her weight against the ancient stones, her battered muscles straining, feeling every aching spot where a bullet had struck.  She dug her feet into the slate floor, reaching for strength that seemed just out of her grasp.  What if she’d reached the limits of her might and she couldn’t protect them?  No.  She refused the thought.  She sucked in her breath and doubled her effort, grunting with the strain, the threads of her dress popping.
“I am never wearing anything without straps again,” she growled.
Something in the temple creaked.  Diana whispered a quick prayer to the goddesses, begging that they would seek Isis’s forgiveness on her behalf and pushed.  The stone beneath her palms shuddered.
“Now!” she shouted.
The temple collapsed with a thunderous roar, sending a huge plume of dust into the air.  She drove her legs forward, and the wide heap of stone groaned as it slid into place, blocking off the northwest corridor of the window wall-- the perfect barricade to keep the soldiers at bay as Alia and the others escaped.
