He didn't sleep.
Just sat there through whatever passed for night in the Brine, pressing the same problem over and over until grey light crept through the cracks in the stone.
By then he knew three things.
They needed to leave before the trader found another use for him.
They needed to reach the Hollows before dark.
And he had one idea worth trying before they got there.
They left before the camp stirred.
"The Hollows are two days west," Wick said, scanning the dunes. "Maybe less if we push hard."
"What's in the Hollows?"
"People who don't ask questions. People who won't sell you to the first collector who offers coin."
"So it's safer."
"No. Just less organized."
Ember looked at his wrapped wrist. The mark pulsed steady beneath the cloth.
Two days. I have two days to figure out if this works or we walk into the Hollows with me spreading faster than I can count.
The dunes swallowed them quickly. Grey sand. Black rocks. That corpse-colored sky that never changed.
The mark pulsed the moment they cleared the Spires. Like it had been holding its breath inside the stone walls.
Hungry. Free. Awake.
"Yeah, yeah. I hear you."
Kaelen glanced at him.
"Talking to it now?"
"Seemed rude not to. It never shuts up anyway."
Something in her face shifted. Not warmth. Just less cold.
Ember kept his wrapped arm close and his mind working. Turning the same problem the way he used to turn numbers that wouldn't balance.
Column four. Still mostly empty.
What does the mark not expect? What does a collector never see coming?
Somewhere between the cold stone floor and this grey morning, it had found him.
A tithe. Not a feast.
Give it just enough to quiet the hunger. The smallest offering to keep the collector from breaking down the door and seizing everything at once.
Worth trying. Going to hurt like hell.
Wick walked ahead, scanning the horizon. His hand drifted to his wrist without thinking. That slow unconscious motion. Like touching something that used to be there and wasn't anymore.
Ember watched it a moment then looked away.
Everyone here carried something invisible.
An hour in, Wick stopped.
Raised his fist.
The sand ahead was moving. That familiar bulge. That slow terrible rising.
One scavenger.
Wick had an arrow nocked before Ember could breathe.
"Wait."
"It will attack."
"Maybe. Give me thirty seconds. I need to test something before we reach the Hollows."
Wick's jaw tightened. "Thirty seconds."
The scavenger broke the surface. White. Translucent. Its maw splitting open.
Ember unwrapped his wrist. Let the violet light bleed out.
The scavenger stopped. Head tilting.
Right. Here we go. Don't panic. Don't let it take over. Don't die.
He reached.
Not with everything. Just the edge. Like pressing one finger against something burning to test how much heat it held.
The mark lunged forward like a chain snapping taut.
*Feed. All. Now.*
"No. Just this much."
He pushed forward. Narrow. Controlled. Like cracking a door open the smallest amount and holding it there with everything he had.
The scavenger swayed. Skin flickered grey at the edges. Stumbled. Fell.
Not ash. Not dead. Just hollowed slightly.
Ember cut the connection.
The mark recoiled. Furious.
*Why. More. Finish it.*
"Because I said so."
He rewrapped his wrist. Hands shaking. The veins hadn't spread. He counted every dark line carefully.
Fourteen. Same as this morning.
Column four. First entry: A tithe. The smallest toll. Enough to quiet the collector without emptying the vessel.
"Holy sh*t. The stupid bloody thing actually worked."
Wick stared at him. "What did you just do?"
"Gave it just enough to keep it quiet. Let it drink shallow then cut it off."
Kaelen looked at the half-drained scavenger. Then at his arm.
"You controlled the measure."
"Balanced the toll. It wanted everything. I gave it the smallest offering I could hold."
Wick put an arrow through the scavenger. Clean. Black flame.
"We move. And you're going to explain exactly what you just did while we walk."
They walked fast. The Hollows were still a day and a half away and Wick wanted to cover ground before the heat peaked.
"The mark wants to drain things completely," Ember said, keeping pace beside Kaelen. "But what if I give it just enough to satisfy the hunger without letting it gorge?"
"Like rationing."
"Like making the smallest payment to keep the collector quiet."
She was silent for a moment.
"My brother tried something similar once. With his mark. Tried to use it in small amounts."
"Did it work?"
"For three days. Then the mark stopped listening to him entirely. Started taking what it wanted whether he willed it or not."
Ember looked at his wrapped wrist.
Three days. That's all he got.
"How long after that before he..."
"Four days. He walked into the dunes on the seventh night."
Seven days total. From trying to control it to losing himself completely.
"I'm sorry."
"Don't be. Just be careful. The mark will learn. And when it learns, it stops playing along."
By midday they'd encountered three more scavengers.
Ember tested the measure each time.
The first went clean. Controlled toll. Scavenger collapsed hollow but breathing.
The second fought. Its maw found his arm before he'd set himself. Pain flared hot.
Ember grabbed its head.
The mark surged. A flood behind a cracking dam.
*Let me. Let me. LET ME.*
"Not f*cking yet."
He hauled the connection back. Hard.
Hold it. Just the tithe. You've done this before.
He pushed forward. Controlled. The scavenger went grey. Slumped.
Still breathing.
He cut the connection.
The mark went silent.
Not defeated. Not worn down.
Watching.
The third scavenger had slipped away while he wasn't paying attention.
Smart creature.
He counted the veins. Fourteen. Same as before.
He was certain.
What he didn't notice was the fifteenth. Thin as a thread of hair. Growing from the very edge of where the others stopped. Moving so slowly it wouldn't show until morning.
The mark pulsed once. Slow. Settled.
Like something that had received exactly what it came for.
They stopped when the sky darkened. Still half a day from the Hollows.
Kaelen handed him food. He ate without tasting it.
"Three times today." Wick worked at his bow. "You held it three times."
"Twice clean. Once barely."
"More than anyone's managed."
"It's not winning. The weight is still there. I'm just pressing back harder."
"But it's not spreading."
"Today."
Tomorrow I'll either say the same thing or I won't be able to say anything at all.
"It knows what you're doing," Kaelen said. "The mark. It stopped fighting. It's letting you measure the toll."
Like a collector who'd found his debtor had discovered a delay and was now watching to see how long it would last.
"Why would it let me?"
"Because you're doing something it hasn't seen before."
"And when it figures out the shape of it?"
"Then we find out which one of you is better at reckoning."
He didn't sleep.
Sat in the grey dark listening.
The mark pulsed slow and patient.
Not hungry. Not pressing.
Just watching.
Column four had one entry. The tithe. The measured toll.
But that settled silence after the second scavenger bothered him.
It got something. Something I didn't account for.
He thought about the entity in his apartment. The way it had regarded him like he was a claim that had finally come due.
What if the debt wasn't his?
Debts can be moved. Passed on. Laid at another door.
What if I'm not the debtor?
What if I'm the ledger itself?
The most dangerous person in any reckoning isn't the one who wants the most.
It's the one who decides where the debt falls.
Outside:
**THOOM.**
Closer.
The mark pulsed back.
*Recognition. Soon.*
And underneath.
*Curiosity. Satisfaction.*
He counted the veins a third time in the dark.
Still fourteen.
Almost certain.
Almost.
Then he heard it.
Boots on sand. Multiple sets. Moving slow. Deliberate.
Wick was already on his feet. Bow drawn.
Ember looked toward the sound.
Three figures. No, four. Emerging from the grey dark.
Not scavengers.
Hunters.
And they were looking straight at him.
"Found you," one of them said. "The marked one from the Spires. The trader sends his regards."
