Curious, Vin tested the lines with her mind, trying to discover their secret. She focused on a particularly small and innocent-looking one, and found that she could feel it individually if she concentrated. She almost felt like she could touch it. She reached out with her mind and gave it a slight tug.
The line shook, and something immediately flew out of the darkness toward her. Vin yelped, trying to jump away, but the object—a rusty nail—shot directly toward her.
Suddenly, something grabbed the nail, ripping it away and throwing it back out into the darkness.
Vin came up from her roll in a tense crouch, mistcloak fluttering around her. She scanned the darkness, then glanced at Kelsier, who was chuckling softly.
