“Because that’s what works. How it works. Because we can, and no one else can. Because it is our legacy. Because if a malice, every malice, is not killed when it emerges, it just keeps growing. And growing. And getting stronger and smarter and harder to get at. And if there is ever one we can’t get, it will grow till the whole world is gray dust, and then it, too, will die. When I said you’d saved the world yesterday, Spark, I was not joking. That malice could have been the one.”

Fawn lay back, clutching her sheets to her breast, taking this in. It was a lot to take in. If she had not seen the malice up close—the rock-dust scent of its foul breath still seemed to linger in her nostrils—she was not sure she could have understood fully. I still don’t understand. But oh, I do believe.

“We just have to hope,” Dag sighed, “that we run out of malices before we run out of Lakewalkers.”

He held the sheath-pouch down on his thigh with his stump and pulled out the blue-hilted knife. He cradled it thoughtfully for a moment, then, with a look of concentration, touched it to his lips, closing his eyes. His face set in disturbed lines. He laid the knife down exactly between himself and Fawn, and drew back his hand.

“This brings us to yesterday.”

“I jabbed that knife into the malice’s thigh,” said Fawn, “but nothing happened.”

“No. Something happened, because this knife was not primed, and now it is.”

Fawn’s face screwed up. “Did it suck out the malice’s mortality, then? Or immortality? No, that makes no sense.”

“No. What I think”—he looked up from under wary brows—“mind you, I’m not sure yet, I need to talk with some folks—but what I think is, the malice had just stolen your baby’s ground, and the knife stole it back. Not soul, don’t you go imagining trapped souls again—just her mortality.” He added under his breath, “A death without a birth, very strange.”

Fawn’s lips moved, but no sound came out.

“So here we sit,” he went on. “The body of this knife belongs to me, because Kauneo willed me her bones. But by our rules, the priming in this knife, its mortality, belongs to you, because you are its next of kin. Because your unborn child, of course, could not will it herself. Here things get really…get even more mixed up, because usually no one is allowed to will and give their priming till they are adult enough to have their groundsense come in fully, about fourteen or fifteen, and older is stronger. And anyway, this was a farmer child. Yet no death but mine should have been able to prime this knife. This is a…this is a right mess, is what it is, actually.”
