Mistborn #01 The Final Empire

“Leave that metal and its partner alone for the moment. They’re a bit more complicated than the others.”
    “What . . .?” Vin asked, tracing the lines of blue light with her eyes. They pointed at random objects. Doors, windows—a couple even pointed at Kelsier.
    “We’ll get to it,” he promised. “Extinguish that one and try one of the last two.”
    Vin extinguished the strange metal and ignored its companion, picking one of the last metals. Immediately, she felt a strange vibration. Vin paused. The pulses didn’t make a sound that she could hear, yet she could feel them washing across her. They seemed to be coming from Kelsier. She looked at him, frowning.
    “That’s probably bronze,” Kelsier said. “The internal mental Pulling metal. It lets you sense when someone is using Allomancy nearby. Seekers, like my brother, use it. Generally it’s not that useful—unless you happen to be a Steel Inquisitor searching for skaa Mistings.”
    Vin paled. “Inquisitors can use Allomancy?”
    Kelsier nodded. “They’re all Seekers—I’m not sure if that’s because Seekers are chosen to become Inquisitors, or if the process of becoming an Inquisitor grants the power. Either way, since their main duties are to find half-breed children and noblemen who use Allomancy improperly, it’s a useful skill for them to have. Unfortunately, ‘useful’ for them means ‘rather annoying’ for us.”
    Vin began to nod, then froze. The pulsing had stopped.
    “What happened?” she asked.
    “I started burning copper,” Kelsier said, “the companion to bronze. When you burn copper, it hides your use of powers from other Allomancers. You can try burning it now, if you want, though you won’t sense much.”
    Vin did so. The only change was a feeling of slight vibration within her.
    “Copper is a vital metal to learn,” Kelsier said. “It will hide you from Inquisitors. We probably don’t have anything to worry about tonight—the Inquisitors would assume us to be regular noble Mistborn, out for training. However, if you’re ever in a skaa guise and need to burn metals, make sure you turn on your copper first.”
    Vin nodded appreciatively.
    “In fact,” Kelsier said, “many Mistborn keep their copper on all the time. It burns slowly, and it makes you invisible to other Allomancers. It hides you from bronze, and it also prevents others from manipulating your emotions.”
    Vin perked up.
    “I thought that might interest you,” Kelsier said. “Anyone burning copper is immune to emotional Allomancy. In addition, copper’s influence occurs in a bubble around you. This cloud—called a coppercloud—hides anyone inside of it from the senses of a Seeker, though it won’t make them immune to emotional Allomancy, like it will you.”
    “Clubs,” Vin said. “That’s what a Smoker does.”
    Kelsier nodded. “If one of our people is noticed by a Seeker, they can run back to the lair and disappear. They can also practice their abilities without fear of being discovered. Allomantic pulses coming from a shop in a skaa sector of town would be a quick giveaway to a passing Inquisitor.”
    “But, you can burn copper,” Vin said. “Why were you so worried about finding a Smoker for the crew?”
    “I can burn copper, true,” Kelsier said. “And so can you. We can use all of the powers, but we can’t be everywhere. A successful crewleader needs to know how to divide labor, especially on a job as big as this one. Standard practice has a coppercloud going at all times in the lair. Clubs doesn’t do it all himself—several of those apprentices are Smokers too. When you hire a man like Clubs, it’s understood that he’ll provide you with a base of operations and a team of Smokers competent enough to keep you hidden at all times.”
    Vin nodded. However, she was more interested in copper’s ability to protect her emotions. She would need to locate enough of it to keep it burning all the time.
    They started walking again, and Kelsier gave her more time to get used to burning tin. Vin’s mind, however, began to wander. Something didn’t feel . . . right to her. Why was Kelsier telling her all of these things? It seemed like he was giving away his secrets too easily.
    Except one , she thought suspiciously. The metal with the blue lines. He hasn’t gone back to it yet. Perhaps that was the thing he was going to keep from her, the power he would hold in reserve to maintain control over her.
    It must be strong.
