The grey dunes didn't end.
They just kept going. Rolling. Shifting. Like the entire world was made of ash and bone-sand and nothing else.
Ember's legs burned. Each step felt like lifting lead. The ichor from the scavenger had dried on his skin, cracking when he moved. It smelled like rot and copper and something chemical that made his eyes water.
"How far?"
His voice came out hoarse.
No one answered.
Wick was ahead, bow still drawn, scanning the dunes. Kaelen walked beside Ember, close enough to grab him if he fell but not close enough to be kind about it.
"Seriously. How far to wherever we're going?"
Kaelen glanced at him.
"The Spires. Another hour. Maybe less if you don't collapse."
"The Spires. Great. That sounds welcoming."
She didn't respond.
The mark on his wrist pulsed beneath the cloth. Still hot. Still wrong. The veins that had spread up his arm hadn't faded. Dark lines under his skin like infection.
He looked at his hand. The fingers twitched without him telling them to. Because something else was moving them.
"That's new. That's definitely new and definitely bad."
Behind them, far in the distance, came the sound.
**THOOM.**
The Reaper. Still following. Still patient.
Wick's shoulders tensed. He didn't look back.
"It's still there."
Ember's voice was flat.
"Of course it's still there. Why wouldn't it be."
Kaelen's hand went to her belt where the vials of salt were strapped.
"It's not getting closer. Just watching."
"Oh good. Being watched by a thirty-foot debt monster. That makes me feel so much better."
She almost smiled. Almost.
"You get used to it."
"Do you? Do you really?"
She didn't answer.
They walked.
***
The Spires appeared suddenly. One moment there was nothing but grey sand and black rocks. The next, they rose from the dunes like broken teeth.
They weren't buildings exactly. More like structures made of black stone and salt and something else that pulsed faintly with the same sickly light as the sky.
Around the base of the Spires, figures moved. People. Dozens of them.
Relief hit Ember so hard he almost fell.
"Other people. There are other people here. I'm not—"
"Don't."
Kaelen's voice was sharp.
"Don't what?"
"Don't think they're going to help you. The Spires are neutral ground. That's all."
"Neutral ground. Right. That's comforting."
They descended into a shallow valley. The Spires grew larger, taller. At their base, Ember could see makeshift camps. Tents made of grey cloth. Fires that burned without smoke. People in rags and armor and things that didn't fit either category.
Some were missing limbs. Arms ending in stumps wrapped in salt-crusted bandages. One man had no eyes, just empty sockets that wept black tears.
"Welcome to the Brine."
Ember's voice was quiet.
"This is what survival looks like."
Wick stopped at the edge of the camps and turned to face Ember.
"Listen carefully. When we get in there, you don't talk. You don't ask questions. You don't show your wrist."
"Don't show my wrist. Got it. Why?"
"Because people here notice things. And what you're carrying..." Wick gestured at Ember's wrapped arm. "That gets noticed fast."
"What happens if someone sees it?"
Wick's jaw tightened.
"Nothing good."
Kaelen unwrapped a new strip of cloth from her pack. Thicker than the first. Almost black.
"Give me your wrist."
Ember held it out. She wrapped the cloth tight, three layers, then tied it with something that looked like wire.
"Keep it covered. Don't let anyone touch it."
"Why would someone—"
"Just don't."
They entered the camps.
People stared. Not at Wick or Kaelen. At Ember.
At his clothes that were still mostly clean except for the dried ichor. At his skin that had no scars, no missing pieces. At the way he walked like someone who didn't know the rules yet.
"Fresh meat."
Someone whispered it loud enough for Ember to hear.
"I heard that. I definitely heard that."
Kaelen's hand went to his arm and pulled him forward.
"Don't stop. Don't look at them. Just walk."
They passed a group clustered around a fire. One of them was sharpening a blade. Another was eating something grey and writhing.
Ember's stomach turned.
"Is that—"
"Don't ask."
They reached the trading post. A structure built into the base of the largest Spire. Black stone walls. No door, just an opening that led into darkness.
Inside, the air was colder. Damp. It smelled like salt and old blood.
A figure sat behind a makeshift counter. Their skin was grey. Eyes milky white. Hands too long, too thin. It was hard to tell if they were old or something else entirely.
"Wick. Kaelen."
The voice was like gravel scraping stone.
"And something new."
The figure leaned forward, staring at Ember. Not at his face. At his wrapped wrist.
Wick stepped forward.
"We need shelter. Three nights."
"Do you."
The figure didn't look away from Ember.
"What's he carrying?"
"Nothing that concerns you."
"Everything in the Spires concerns me."
The figure stood. Taller than Ember expected. Taller than Wick.
"Let me see."
"No."
Kaelen's voice was flat.
"I wasn't asking the girl."
The figure moved around the counter. Slow. Deliberate. Stopped in front of Ember.
"Show me your wrist."
"I don't—"
"Show me."
Something in the voice made Ember's skin crawl. Not a request or a demand. A certainty.
"No. I'm not—"
The figure grabbed Ember's arm. Fast. Too fast for him to react.
Ember tried to pull back. The grip was iron.
"Let go—"
The figure unwrapped the cloth. One layer. Two. Three.
The violet light spilled out. Bright. Pulsing.
The figure froze.
Stared at the mark and the veins spreading up Ember's arm.
Then laughed. Quiet. Wrong.
"You let it drink."
"I don't know what—"
"You fed it something. And it liked it."
The figure let go and stepped back.
"How many?"
"How many what?"
"How many have you killed?"
Ember's throat closed.
"I didn't—it wasn't—"
"One. He's only killed one."
Kaelen's voice cut through, sharp.
The figure tilted its head, still staring at Ember.
"One. And it's already spreading. Already hungry."
The figure looked at Wick.
"You brought me something interesting."
"We brought you nothing. We need shelter. That's all."
"Shelter." The figure smiled. Too many teeth. "Of course. Three nights. I can do that."
"What's the price?"
"Nothing. Shelter is free."
Wick's hand went to his bow.
"Nothing is free."
"You're right."
The figure walked back behind the counter and sat down.
"Shelter is free. But leaving..." The figure gestured at Ember. "That costs something."
"What are you talking about?"
Ember's voice cracked.
"There's a nest. Two hours west. Scavengers. Twenty, maybe thirty of them. My hunters won't touch it. Too many losses."
The figure leaned forward.
"But you. You could handle it. Couldn't you."
"I'm not—I can't—"
"You already did. You killed one. Fed your mark. Felt it work."
"That was different. That was—"
"That was survival. And this?" The figure gestured at the camps outside. "This is the same thing."
"I'm not clearing a nest for you. I'm not like some—"
"Then you can leave. Right now. Walk back into the dunes. See how long you last without shelter. Without water. Without protection from the hunters out there who'd love to get their hands on someone like you."
Ember's fists clenched.
"You can't—"
"I can. And I am."
The figure sat back.
"Three nights. Then you clear the nest. Or you leave. Your choice."
"That's not a choice. That's extortion."
"That's how things work here."
Silence.
Ember looked at Wick, then at Kaelen. Waiting for them to say something. Anything.
They said nothing.
"This is insane. I'm not—I can't do this. I don't even know what I'm doing. I don't know how the mark works. I don't—"
"You'll figure it out."
The figure pointed to a doorway in the back.
"Your shelter. Don't leave the Spires after dark."
Ember didn't move.
"And if I refuse?"
"Then I'll tell the hunters outside that you're carrying something valuable. Something that works. And they'll make you an offer. One you'll like even less than mine."
The figure's smile widened.
"At least I'm letting you keep your limbs."
Ember's hands shook. His breath came short.
"I don't have a choice. Do I."
"No one does."
Ember turned and walked toward the doorway. Each step felt like lead.
Wick and Kaelen followed.
Behind them, the figure called out.
"Tomorrow night. Don't be late."
The shelter was small and cold. A room carved into the Spire. No light. No warmth. Just stone and darkness.
Ember sat down with his back against the wall, staring at his wrist.
The cloth was back on, but he could still see the glow beneath it. Pulsing. Hungry.
"Tomorrow night. I have to use it again tomorrow night."
His voice was quiet.
Kaelen leaned against the doorway.
"Yes."
"And if I don't?"
She didn't answer.
Didn't need to.
Wick sat in the corner, cleaning his bow, not looking at Ember.
"You could run."
Ember looked up.
"What?"
"You could run. Right now. Out the back. Into the dunes. Take your chances."
"Would I make it?"
"No."
"Then why suggest it?"
Wick finally looked at him.
"Because at least you'd die free."
Silence.
Ember looked at his wrist again. At the veins. At the wrongness spreading.
"I'm trapped. Aren't I. There's no way out of this."
Kaelen's voice was quiet.
"There never was."
Outside, beyond the Spires, beyond the camps, came the sound.
**THOOM.**
The Reaper. Still watching.
Still waiting.
Ember closed his eyes.
Tomorrow night. He'd have to use the mark again. Feed it again. Let it drink.
And the cost...
He looked at his arm. At the dark veins. At the fingers that twitched on their own.
The cost was already spreading.
