Mistborn #01 The Final Empire

The most powerful of the eight.
    As they walked through the quiet streets, Vin reached tentatively inside. She eyed Kelsier, then carefully burned that unknown metal. Again, the lines sprang up around her, pointing in seemingly random directions.
    The lines moved with her. One end of each thread stayed stuck to her chest, while the other end remained attached to a given place along the street. New lines appeared as she walked, and old ones faded, disappearing behind. The lines came in various widths, and some of them were brighter than others.
    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.
    “I should have known you’d try that,” he said.
    Vin flushed in embarrassment.
    “Come on,” he said, waving her over. “No harm done.”
    “The nail attacked me!” Did that metal bring objects to life? That would be an incredible power indeed.
    “Actually, you kind of attacked yourself,” Kelsier said.
    Vin stood carefully, then joined him as he began to walk down the street again.
    “I’ll explain what you did in a moment,” he promised. “First, there’s something you have to understand about Allomancy.”
    “Another rule?”
    “More a philosophy,” Kelsier said. “It has to do with consequences.”
    Vin frowned. “What do you mean?”
    “Every action we take has consequences, Vin,” Kelsier said. “I’ve found that in both Allomancy and life, the person who can best judge the consequences of their actions will be the most successful. Take burning pewter, for instance. What are its consequences?”
    Vin shrugged. “You get stronger.”
    “What happens if you’re carrying something heavy when your pewter runs out?”
    Vin paused. “I suppose you’d drop it.”
    “And, if it’s too heavy, you could hurt yourself seriously. Many a Misting Thug has shrugged off a dire wound while fighting, only to die from that same wound once their pewter ran out.”
    “I see,” Vin said quietly.
    “ Ha! ”
    Vin jumped in shock, throwing her hands up over her enhanced ears. “Ow!” she complained, glaring at Kelsier.
    He smiled. “Burning tin has consequences too. If someone produces a sudden light or sound, you can be blinded or stunned.”
    “But, what does that have to do with those last two metals?”
    “Iron and steel give you the ability to manipulate other metals around you,” Kelsier explained. “With iron, you can Pull a metal source toward yourself. With steel, you can Push one away. Ah, here we are.”
    Kelsier stopped, looking up ahead.
    Through the mist, Vin could see the massive city wall looming above them. “What are we doing here?”
    “We’re going to practice Ironpulling and Steelpushing,” Kelsier said. “But first, some basics.” He pulled something out of his belt—a clip, the smallest denomination of coin. He held it up before her, standing to the side. “Burn steel, the opposite of the metal you burned a few moments ago.”
    Vin nodded. Again, the blue lines sprang up around her. One of them pointed directly at the coin in Kelsier’s hand.
    “All right,” Kelsier said. “Push on it.”
    Vin reached toward the proper thread and Pushed slightly. The coin flipped out of Kelsier’s fingers, traveling directly away from Vin. She continued to focus on it, Pushing the coin through the air until it snapped against the wall of a nearby house.
    Vin was thrown violently backward in a sudden, jerking motion. Kelsier caught her and kept her from falling to the ground.
    Vin stumbled and righted herself. Across the street, the coin—now released from her control—plinked to the ground.
    “What happened?” Kelsier asked her.
    She shook her head. “I don’t know. I Pushed on the coin, and it flew away. But when it hit the wall, I was pushed away.”
    “Why?”
    Vin frowned thoughtfully. “I guess . . . I
