By the time the Custodian finished smiling, Aros had already decided.
The rest was counting.
Ten paces. The Custodian with the humming sword stood ten paces away, smiling at a girl who was pretending to pray. Eleven masked Custodians still on the platform. Four more at the eastern gate, two at the western. A thousand people on their knees between them, and every one of those people believed they had just seen a miracle.
Behind the arcade, an alley. Behind the alley, the fish market. Behind the fish market, the docks.
He didn't look at the alley. Looking at an exit was the surest way to tell a man where you meant to go.
"Stand up, child," the Custodian said. His voice was soft, almost kind. "The Light wishes to see you."
Gemma didn't move. Good girl. Aros felt her shaking against his arm, a fine tremor like a plucked string.
The fishwife kneeling between them and the Custodian lifted her head, confused, looking from the sword to the girl and back. Somewhere near the platform, a priest was still chanting, unaware that the ceremony had already ended.
Aros had seen what those blades did. He couldn't have said where anymore. There were years he'd stopped thinking about, and some of them he couldn't have found again if he tried. His body remembered, though: a shield splitting like wet paper, and a man on the other side of it who hadn't had time to look surprised.
You didn't fight a blessed blade in a crowded square with a fisherman's knife.
So Aros did the only thing a thousand frightened believers would understand.
He pointed across the square, at the far arcade, at nothing at all, and screamed.
"Heretic! There! The fire was for him!"
Every head in Calad turned, and the bodies followed the heads. The kneeling crowd lurched upright in one great wave of wool and salt and panic, shouting, shoving, a woman shrieking that she'd seen him too, a man swearing he'd seen the devil's face. The miracle became a stampede in the space of a breath.
Aros was already moving.
He pulled Gemma up and into the current of bodies, keeping her low, keeping her small, using the crowd the way a swimmer uses a rip tide. Somebody's elbow caught him in the ribs. Somebody's basket burst and silver fish spilled across the stones. He didn't look back.
"Aros..."
"Run now. Talk later."
The alley swallowed them.
It was narrow and wet and smelled of tar and old rope, and the noise of the square fell away behind them as if a door had closed. Gemma ran beside him without being told, small boots slapping the puddles, her hood fallen back now and her white hair loose. He hated that hair. He'd tried dyeing it once with walnut husks. The dye had washed out in the first rain, and she'd laughed at him for a week.
They took the first left, then a stair, then a passage between two warehouses so tight that Aros had to turn his shoulders to fit. He'd learned Calad's back streets before they arrived, the way he learned every town: the low walls, the drains, the doors nobody bothered to lock.
"Will he follow?" Gemma gasped.
"Yes."
"How does he..."
"I don't know. Breathe through your nose."
The passage opened onto the fish market. At this hour it should have been empty, the stalls shuttered, the gutting tables scrubbed for the day of purification. Instead, the sound of the bells had driven the few workers inside, and the market was a maze of hanging nets and stacked barrels, lit by grey light coming in off the sea.
And standing in the middle of it, between them and the docks, were two Custodians.
They hadn't come from the square. They must have been posted here, guarding the harbor road, the way the Priesthood guarded every road on a day like this. Ivory robes. Bone masks. Long maces hanging at their belts, the heads shaped like small suns.
They turned at the same moment, with the same smooth economy, like two halves of the same body.
"Halt," said the one on the left. "In the name of the Light."
Aros let go of Gemma's hand.
"Behind the barrels," he said quietly. "Close your eyes."
She didn't close her eyes. She never did.
The Custodians came at him together, and the way they moved told him what he needed. They were strong and well drilled, and they were used to crowds, to people who fell down and begged. Their carved masks covered half their vision. Nobody had ever made them pay for that.
Aros went left and low, into the blind side of the first mask.
The mace whistled through the air where his head had been. His knife came up under the jaw, where the mask's leather strap met the throat, and went in to the hilt. He felt the man's weight change, the sudden heaviness of a body that has stopped holding itself up. He turned with it, using the dying Custodian as a shield, and the second mace struck the first man's back with a sound like a dropped sack of grain.
He pulled the knife free. The second Custodian was already raising the mace again, faster than Aros expected, and for a fraction of a heartbeat he felt the old cold clarity slip. Too old. Too slow. The thought arrived with the mace.
He didn't block. He stepped inside the swing, so close he could smell the incense in the man's robes, and drove the knife into the gap beneath the mask, the place where a carved bone face pretended to have a mouth.
The blade went in. It didn't come out. It had caught on something, bone or carved ivory, and the Custodian fell backward with Aros's knife still wedged in the mask.
Two men. Perhaps four seconds.
The market was quiet again, except for the drip of water from the nets and Aros's own breathing, which was louder than he liked. His hands were steady. They were always steady. That was the part that frightened people, when they saw it. It had frightened him too, once.
He put his boot on the dead man's chest and pulled at the knife. It didn't move.
"Aros." Gemma's voice, behind the barrels. Very small. "He's coming."
He didn't ask who. He could hear it too: footsteps on the stairs behind them, unhurried, and under the footsteps a faint hum.
There was no time to free the knife. There was no time to reach the docks, either: the market floor was open stone from here to the water, forty paces of it, and a man with a sword like that would not need more than a glance.
Aros grabbed Gemma by the wrist and pulled her down behind a wall of stacked barrels, under a fishing net hung to dry, into a gap that smelled of brine and rotten bait. He pressed his back to the wood. She folded herself against his side.
The footsteps reached the bottom of the stairs.
Through a crack between two barrels, Aros watched the Custodian walk into the market. He didn't hurry. He looked at the two bodies on the stones the way a man looks at a word written in a language he once studied. Then he lifted the sword.
The hum rose.
Aros felt it this time, not in his ears but in his teeth, in the old scar along his jaw. The blade turned slowly, sweeping the market. Its edge passed through a hanging net, and the ropes parted without a sound; an iron hook as big as a man's hand dropped to the stones in two pieces. The Custodian didn't even glance at it. The blade slowed as it passed the barrels.
It stopped.
"He hears me," Gemma whispered. Her lips barely moved. "Every time I breathe, he hears me."
"Then don't breathe."
"I can't hold it that long." Her hand found his sleeve and gripped it. "Let me try something."
He looked down at her. She wasn't looking at him. She was looking at her own hands, pale in the shadow, cupped together in her lap as if she were holding water.
"Gemma, no..."
"It listens back," she said. "In the square, when I closed the door, it listened. So I'm going to ask it to be quiet."
Before he could stop her, she closed her eyes.
At first nothing happened. Then the air between her palms changed. A thin pale line drew itself there, more the memory of light than light, in a circle no bigger than a coin. It trembled. It steadied. And then, so slowly that Aros could have mistaken it for his own eyes adjusting to the dark, the circle widened.
It passed through her wrists. Through her knees. Through his arm where she held it, cold as a ring of frost, and kept going until it surrounded them both, a faint pale band hanging in the air at the height of his heart.
And the world went silent.
The drip of the nets stopped, and the bells, and the hum of the sword, all at once. Aros could see water falling from the nets and gulls wheeling over the harbor with their beaks open, but he couldn't hear any of it. All he could hear was his own pulse.
On the other side of the barrels, the Custodian frowned.
The sword wavered. Its point drifted away from them, uncertain, a hound that has lost the scent in running water. It swung left. It swung right. It dipped, as if the blade itself were confused.
A second figure came running down the stairs: another Custodian, masked, breathless. His mouth moved. Inside the circle Aros couldn't hear the words, but he could read them easily enough. Brother Lukas.
So the man had a name.
Lukas didn't answer at once. He crouched beside the second body and studied the knife standing out of the mask. He touched the hilt with two fingers. Then he looked at the throat of the first man, at the narrow wound beneath the jaw, where leather met skin.
Aros watched his face change, and what came into it looked a lot like delight.
Lukas stood and looked around the market once more: the open floor, the stacked barrels, the single gate that led out to the harbor. The sword hung dead in his hand. Aros could almost watch him work it out. A man and a girl running from the square would make for the water, and from here there was only one way to the water. Lukas said something short to the other Custodian and pointed toward the harbor gate. The masked man ran. Lukas followed him, unhurried, the sword low at his side, to wait for them where they would have to pass.
They were gone.
Gemma made a small sound, and the ring broke.
Noise rushed back in all at once: water, gulls, bells, the slap of the sea against the pilings. Gemma sagged against him. When Aros turned her face toward the light, there was blood running from her nose, bright and sudden, dripping off her chin onto her cloak.
"It's nothing," she said, before he could ask. Her voice was thick. "It's just... it didn't want to stop. I had to make it stop."
He wiped her face with his sleeve, harder than he meant to. His hands were shaking now. They hadn't shaken during the fight.
"You did that," he said. "On purpose."
"I asked it." She looked up at him, and under the blood and the fear he saw something new in her face. She looked amazed. "Aros. It answered."
He didn't know what to say to that, so he said the only thing that mattered.
"Can you walk?"
She nodded.
They went under the market, not across it: down a ladder slick with weed, onto the narrow ledge beneath the pier where the fishermen tied the boats they didn't trust to the harbor master's ledger. Aros cut the rope on the first skiff that looked like it would float, set Gemma in the bow, and pushed off into the fog with an oar.
The harbor gate was closing. He could hear the chains. Somewhere above them, a horn was blowing three short notes, again and again, the signal to seal the port. But the fog was thick on the water, and a small boat with no lantern was nothing but a shadow among shadows, and the tide was going out.
He rowed. Calad slid backward into the grey: the towers, the saints on the parapets, the white smoke still rising from the square where a fisherman named Benat had told the Light it didn't belong to anyone.
Gemma sat hunched in the bow, pressing a rag to her nose. For a long time she didn't speak.
"There was a woman in his sword," she said finally. "She was crying. And when the fire reached for me, I heard someone say my name."
"I know."
"I want to know who she is."
"No."
"I'm going to find out anyway."
He kept rowing. He didn't argue. A year ago he'd found her sitting in the ash of what had been Seborn, holding a bent horseshoe against her chest, and she hadn't spoken a word for three weeks. He'd take stubborn. Stubborn was alive.
When they were nearly clear of the harbor, he looked back one last time.
At the very end of the longest pier, where the fog thinned, a tall figure stood alone. Pale hair. White robes. He wasn't shouting. He wasn't signaling the towers. He was holding something up to the grey light, turning it slowly in his fingers.
Aros's knife.
Then Lukas lowered it and lifted his other hand, the one with the sword, and touched the flat of the blade to his brow. A salute. The kind soldiers give to an enemy they recognize.
He didn't call the towers. He didn't wave for the archers on the harbor wall, who were close enough to hear him. Aros understood why, and he liked it less than any alarm. The man wanted to do this himself.
Aros turned back to the oars.
Ten years. He had spent ten years making the world believe the Kingslayer was dead. He'd buried his family name, changed his town, his trade, the way he walked into a room.
It had taken one girl and one cold morning to undo all of it.
