Nolan figured she must know what she was talking about. She at least knew more than he did. So it would be well worth his while to do what she said if he ever wanted to get out of this alive. He crossed the river, an ice bridge forming under his feet without him having to do much conscious thinking in order to get it there.<br/><br/>He wondered if she could hear the same humming noise that he could. It sounded like technology. Machinery. The sort of things they had in the library where Nolan had lived for so long. He didn't exactly know just what it was, but he knew that every once in a while, he'd cross a wire or two in one of the machines, and something would spark and things would start moving. That hum reminded him of that, though it was far louder and seemed to be rattling his very bones.<br/><br/>Finally, he reached the twinkling thing that Lina was talking about. He wasn't really sure what to do, but he figured that a mirror wouldn't be too resilient.<br/><br/>Hoping that it wouldn't trigger anything too unpleasant or dangerous, he thickened his ice dagger and sharpened it to a fine point. It was hard to see the twinkling clearly, almost as if it disappeared when he tried to look directly at it. And yet, after a moment he got the spot down, took a deep breath, and plunged the point into the wall.
