Peace gave her strength.
Koloss died around her, and scarlet blood—too bright to be human—stained the air. There were ten thousand in this army—far too many for her to kill. However, she didn't need to slaughter every koloss in the army.
She just had to make them afraid.
Because, despite what she'd once assumed, koloss could feel fear. She saw it building in the creatures around her, hidden beneath frustration and rage. A koloss attacked her, and she dodged to the side, moving with pewter's enhanced speed. She slammed a sword into its back as she moved, and spun, noticing a massive creature pushing its way through the army toward her.
Perfect, she thought. It was big—perhaps the biggest one she had ever seen. It had to be almost thirteen feet tall. Heart failure should have killed it long ago, and its skin was ripped half free, hanging in wide flaps.
It bellowed, the sound echoing across the oddly quiet battlefield. Vin smiled, then burned duralumin. Immediately, the pewter already burning inside of her exploded to give her a massive, instantaneous burst of strength. Duralumin, when used with another metal, amplified that second metal and made it burn out in a single burst, giving up all of its power at once.
Vin burned steel, then Pushed outward in all directions. Her duralumin-enhanced Push crashed like a wave into the swords of the creatures running at her. Weapons ripped free, koloss were thrown backward, and massive bodies scattered like mere flakes of ash beneath the bloodred sun. Duralumin-enhanced pewter kept her from being crushed as she did this.
Her pewter and steel both disappeared, burned away in single flash of power. She pulled out a small vial of liquid—an alcohol so1lution with metal flakes—and downed it in a single gulp, restoring her metals. Then, she burned pewter and leaped over fallen, disoriented koloss toward the massive creature she had seen earlier. A smaller koloss tried to stop her, but she caught its arm by the wrist, then twisted, breaking the joint. She took the creature's sword, ducking beneath another koloss's attack, and spun, felling three different koloss in one sweep by cutting at their knees.
As she completed her spin, she rammed her sword into the earth point-first. As expected, the large, thirteen-foot-tall beast attacked a second later, swinging a sword that was so large that it made the air roar. Vin planted her sword just in time, for—even with pewter—she never would have been able to parry this enormous creature's weapon. That weapon, however, slammed into the blade of her sword, which was stabilized by the earth below. The metal quivered beneath her hands, but she held against the blow.
Fingers still stinging from the shock of such a powerful block, Vin let go of the sword and jumped. She didn't Push—she didn't need to—but landed on the cross guard of her sword and leaped off it. The koloss showed that same, characteristic surprise as it saw her leap thirteen feet into the air, leg drawn back, tasseled mist-cloak flapping.
She kicked the koloss directly in the side of the head. The skull cracked. Koloss were inhumanly tough, but her flared pewter was enough. The creature's beady eyes rolled back in its head, and it collapsed. Vin Pushed slightly on the sword, keeping herself up long enough so that when she fell, she landed directly on the felled koloss's chest.
The koloss around her froze. Even in the midst of the blood fury, they were shocked to see her drop such an enormous beast with only a kick. Perhaps their minds were too slow to process what they had just seen. Or, perhaps in addition to fear, they really could feel a measure of wariness. Vin didn't know enough about them to tell. She did understand that in a regular koloss army, what she'd just done would have earned her the obedience of every creature that had watched her.
Unfortunately, this army was being controlled by an external force. Vin stood up straight, could see Elend's small, desperate army in the distance. Under Elend's guidance, they held. The fighting humans would have an effect on the koloss similar to Vin's mysterious strength—the creatures wouldn't understand how such a small force could hold against them. They wouldn't see the attrition, or the dire situation of Elend's group; they would simply see a smaller, inferior army standing and fighting.
Vin turned to resume combat. The koloss approached her with more trepidation, but they still came. That was the oddity about koloss. They never retreated. They felt fear, they just couldn't act on it. It did, however, weaken them. She could see it in the way they approached her, the way they looked. They were close to breaking.
And so, she burned brass and Pushed on the emotions of one of the smaller creatures. At first, it resisted. She shoved harder. And, finally, something broke within the creature and he became hers. The one who had been controlling him was too far away, and was focused on too many koloss at once. This creature—its mind confused because of the frenzy, emotions in a turmoil because of its shock, fear, and frustration—came completely under Vin's mental control.
Immediately, she ordered the creature to attack his companions. He was cut down a moment later, but not before he killed two other koloss. As Vin fought, she snatched up another koloss, then another. She struck randomly, fighting with her sword to keep the koloss distracted as 1she plucked members from their group and turned them. Soon, the area around her was in chaos, and she had a small line of koloss fighting for her. Every time one fell, she replaced it with two more.
As she fought, she spared a glanced for Elend's group again, and was relieved to find a large segment of koloss fighting alongside the group of humans. Elend himself moved among them, no longer fighting, focused on snatching koloss after koloss to his side. It had been a gamble for Elend to come to this city on his own, one she wasn't sure she approved of. For the moment, she was just glad she'd managed to catch up in time.
