The grey-skinned survivors were still in the camp when morning came.
Ember watched them from the shelter entrance. Four of them. Sitting apart from the others. The grey hadn't faded. Just sat there, spreading slowly from where he'd touched them. Like frost that forgot how to stop.
Because of me.
A trader crouched beside one of them. Prodding the grey skin with two fingers. Clinical. Detached. The grey man flinched.
The trader didn't notice. Or didn't care.
Just noted something in his head and moved on.
Already calculating the value.
Ember watched him go.
He hurt four people yesterday. And before the blood had dried, the system had already figured out how to profit from it.
"They're calling it mark-touch."
Wick appeared beside him. Voice low.
"What happens when a marked one drains someone but doesn't finish."
"Will they recover?"
"Don't know. Never seen anyone survive it before."
"Because no one ever pulled back before?"
"Because no one ever could."
Ember's stomach turned.
He sat in the corner and made himself think.
Not panic. Not spiral. Think.
The way he used to at the desk. Late nights. Numbers that wouldn't cooperate. The same process. Column one. Column two. What he had. What he owed.
Column one: Assets.
A mark that worked. Kaelen and Wick, for now. A shoulder wound healing faster than it should. Three nights of shelter, paid. One more night left.
Column two: Liabilities.
Four people with grey spreading across their skin. A camp full of hunters who knew exactly what he carried. A Reaper in the dunes following him since the beginning. A mark slowly replacing him, piece by piece, with something that wasn't him.
Column three: Options.
Stay. The trader would have another nest. Another job. Another reason to keep Ember useful until he wasn't anymore.
Leave. The dunes. The Reaper. The mark hungry and him alone.
Remove the mark. He didn't know if that was possible. And if it was, the cost was probably worse than the alternative.
He stared at the numbers.
Every column came up the same.
No way out that doesn't cost everything.
He'd known that feeling before. Different context. Same arithmetic.
Rent overdue. His sister's clinic bills. The landlord's office three blocks away. Six months of walking past it.
The math always catches up.
"You're doing the face."
Kaelen was watching him from across the shelter.
"What face?"
"Like you're adding something up and it keeps coming out wrong."
"It keeps coming out wrong."
"And?"
"The math is terrible."
She almost smiled. Almost.
"It always is here."
"Tell me about your brother."
Kaelen went very still.
"Why."
Not a question. A warning.
"Because I need to understand what I'm becoming. And you're the only one who's seen it happen to someone close."
She was quiet long enough that he thought she'd refuse.
"He was twelve when he got his mark. I was fifteen. Three weeks into the Brine."
She looked at her hands.
"Small mark. On his palm. He could sense scavengers before they rose. Feel them beneath the sand."
"That sounds useful."
"It was. For a while."
A pause.
"Then it started asking for more. Every time he used it, the mark would push. Not in words. Just hunger. And he'd fight it. Every single time. For weeks he fought it."
"But he couldn't keep fighting forever."
"The mark doesn't get tired. You do."
She stood. Walked to the entrance.
"One morning I woke up and he was sitting there. Just staring at his palm. I asked what was wrong."
She stopped.
"He said: I stopped fighting it last night. And it felt like coming home."
The words landed like something physical.
"Two days later he walked into the dunes."
Silence.
She didn't look at him when she finished. Just stared at the sand outside.
"I've never told anyone that before."
Ember looked at his wrapped wrist. At the glow bleeding through.
"I'm not going to stop fighting it."
Kaelen looked at him over her shoulder.
"That's what he said too."
She turned back to the entrance.
Not cruel. Just honest.
And honesty here was worse than cruelty.
Wick came back before dark. Dropped a pack. Sat without speaking.
Ember let the silence sit for a moment.
"You know too much."
Wick didn't look up.
"Three years in the Brine."
"No. More than that. You know how traders think. How hunters value marks. What happens to people who get drained. You don't learn that from observation."
Wick's jaw tightened.
"What are you asking."
"Which side you were on. Before."
The silence stretched long enough to answer.
"I did what I had to do to survive."
"So did I. Yesterday."
Wick finally looked at him.
"The four you touched. The grey ones. The trader's already planning to move them."
"Where?"
"Researchers. People who study marks. Apparently grey skin that keeps spreading is valuable data."
Ember's hands clenched.
He hurt four people. Before he'd stopped bleeding, the system had already categorized them. Packaged them. Found buyers.
"This whole place is designed to break people like me."
"Yes."
"Use us until we're empty. Then profit from what's left."
"Yes."
"And you helped them do that. Once."
"Yes."
"Why are you helping me now?"
A long pause.
His hand went to his wrist. Rubbing something there. A scar, maybe. Or the memory of one.
"Because I got tired of being useful to people who saw me as a tool."
Ember looked at him.
An ex-hunter with something cut out of his past. A girl whose brother the mark took. And himself. An accountant who lit one candle too many.
Not allies. Not a team.
Just three people with nowhere else to go.
***
Night.
The mark pulsed. Slower now. Like it had settled into a rhythm. Biding its time.
Ember stared at his reflection in the dark stone. Veins at his collarbone. Visible through his shirt.
He thought about the ledger.
Column one. Column two. Column three.
Then a fourth column he hadn't written yet.
What does the mark not expect?
It wanted to drain. To spread. To consume until there was nothing left that was his.
But in the nest he'd fed it poison. Rot. The wrong kind of essence. And the scavengers had choked on it.
What if the mark could be fed the wrong thing again? Not poison. Something subtler. Controlled portions. Calculated doses. Like managing debt repayments.
He looked at his wrapped wrist.
You've been running this since the beginning. The hunger. The spreading. The voice.
But you're not the only one who can calculate.
The mark pulsed.
*Hungry.*
"I know. So am I."
He closed his eyes.
Outside:
**THOOM.**
Closer. Definitely closer.
The mark pulsed back at it. That recognition. That connection.
But this time Ember didn't flinch.
He just added it to the ledger.
Column four: What I haven't tried yet.
