The office didn't vanish from around her, so Mary had obviously decided to hang back. One of the golems was confused by the "smoke" display, swinging wildly at the sheets of light that surrounded it. Not so the second. It advanced on Sly, more slowly now, as though taking time to analyze her armor and find its weak spots. She tried to dodge to the left, but a sweeping arm blocked that move. She backed up again, felt the office wall behind her. No more retreat. No more options.
