Vin nodded. The wealth of sensations was nearly overwhelming. She could hear creaks and scuffles in the darkness, and they made her want to jump in alarm, certain that someone was sneaking up behind her.
This is going to take some getting used to.
“Leave it burning,” Kelsier said, waving for her to walk beside him as he continued down the street. “You’ll want to accustom yourself to the enhanced senses. Just don’t flare it all the time. Not only would you run out of it very quickly, but perpetually flaring metals does . . . strange things to people.”
“Strange?” Vin asked.
“Metals—especially tin and pewter—stretch your body. Flaring the metals only pushes this stretching further. Stretch it too far for too long, and things start to break.”
Vin nodded uncomfortably. Kelsier fell quiet, and they continued to walk, letting Vin explore her new sensations and the detailed world that tin revealed. Before, her vision had been restricted to a tiny pocket within the night. Now, however, she saw an entire city enveloped by a blanket of shifting, swirling mist. She could make out keeps like small, dark mountains in the distance, and could see specks of light from windows, like pin-pricked holes in the night. And above . . . she saw lights in the sky.
She stopped, gazing up with wonder. They were faint, blurred to even her tin-enhanced eyes, but she could just barely make them out. Hundreds of them. Thousands of them. So small, like the dying embers of candles recently extinguished.
“Stars,” Kelsier said, strolling up beside her. “You can’t see them very often, even with tin. It must be a particularly clear night. People used to be able to look up and see them every night—that was before the mists came, before the Ashmounts erupted ash and smoke into the sky.”
Vin glanced at him. “How do you know?”
Kelsier smiled. “The Lord Ruler has tried very hard to crush memories of those days, but still some remain.” He turned, not really having answered her question, and continued to walk. Vin joined him. Suddenly, with tin, the mists around her didn’t seem so ominous. She was beginning to see how Kelsier could walk about at night with such confidence.
“All right,” Kelsier eventually said. “Let’s try another metal.”
Vin nodded, leaving her tin on but picking another metal to burn as well. When she did so, a very strange thing happened—a multitude of faint blue lines sprung from her chest, streaking out into the spinning mists. She froze, gasping slightly and looking down at her chest. Most of the lines were thin, like translucent pieces of twine, though a couple were as thick as yarn.
Kelsier chuckled. “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. 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.
