Mistborn #03 The Hero of Ages

were still concrete, still relevant, it would require great sacrifices of them.
    TenSoon stopped running; he was up to his wolfhound knees in deep black ash. The location looked vaguely familiar. He turned south, moving through a small rocky hollow—the stones now just dark lumps—looking for a place he had been over a year before. A place he'd visited after he had turned against Zane, his master, and left Luthadel to return to the Homeland.
    He scrambled up a few rocks, then rounded the side of a stone outcrop, knocking lumps of ash off with his passing. They broke apart as they fell, throwing more flakes into the air.
    And there it was. The hollow in rock, the place where he had stopped a year before. He remembered it, despite how the ash had transformed the landscape. The Blessing of Presence, serving him again. How would he get along without it?
    I would not be sentient without it, he thought, smiling grimly. It was the bestowing of a Blessing on a mistwraith that brought the creature to wakefulness and true life. Each kandra got one of the four: Presence, Potency, Stability, or Awareness. It didn't matter which one a kandra gained; any of the four would give him or her sentience, changing the mistwraith into a fully conscious kandra.
    In addition to sentience, each Blessing gave something else. A power. But there were stories of kandra who had gained more than one by taking them from others.
    TenSoon stuck a paw into the depression, digging out the ash, working to uncover the things he had hidden a year before. He found them quickly, rolling one—then the other—out onto the rock shelf in front of him. Two small, polished iron spikes. It took two spikes to form a single Blessing. TenSoon didn't know why this was. It was simply the way of things.
    TenSoon lay down, commanding the skin of his shoulder to part, and absorbed the spikes into his body. He moved them through muscles and ligaments—dissolving several organs, then re-forming them with the spikes piercing them.
    Immediately, he felt power wash through him. His body became stronger. It was more than the simple adding of muscles—he could do that by re-forming his body. No, this gave each muscle an extra innate strength, making them work much better, much more powerfully, than they would have otherwise.
    The Blessing of Potency. He'd stolen the two spikes from OreSeur's body. Without this Blessing, TenSoon would never have been able to follow Vin as he had during their year together. It more than doubled the power and endurance of each muscle. He couldn't regulate or change the level of that added strength—this was not Feruchemy or Allomancy, but something different. Hemalurgy.
    A person had died to create each spike. TenSoon tried not to think about that too much; just as he tried not to think about how he only had this Blessing because he had killed one of his own generation. The Lord Ruler had provided the spikes each century, giving the number requested, so that the kandra could craft a new generation.
    He now had four spikes, two Blessings, and was one of the most powerful kandra alive. His muscles strengthened, TenSoon jumped confidently from the top of the rock formation, falling some twenty feet to land safely on the ash-covered ground below. He took off, running far more quickly now. The Blessing of Potency resembled the power of an Allomancer burning pewter, but it was not the same. It would not keep TenSoon moving indefinitely, nor could he flare it for an extra burst of power. On the other hand, it required no metals to fuel it.
    He made his path eastward. The First Contract was very explicit. When Ruin returned, the kandra were to seek out the Father to serve him. Unfortunately, the Father was dead. The First Contract didn't take that possibility into consideration. So—unable to go to the Father—TenSoon did the next best thing. He went looking for Vin.

Originally, we assumed that a koloss was a combination of two people into one. That was wrong. Koloss are not the melding of two people, but five, as evidenced by the four spikes needed to make them. Not five bodies, of course, but five souls.
    Each pair of spikes grants what the kandra would call the Blessing of Potency. However, each spike also distorts the koloss body a little more, making it increasingly inhuman. Such is the cost of Hemalurgy.

    "NOBODY KNOWS PRECISELY how Inquisitors are made," Elend said from the front of the tent, addressing a small group, which included
