The Debt Collector's Dungeon

The tollcrab did not attack. That was the first problem.

Min-jae had a procedure for threats: identify, assess, retreat to a desk. A threat that waited politely for instructions fell outside the procedure.

"Park," he said. "Stop screaming."

"I'm not screaming."

"You're doing a very quiet scream. It's in your throat. Stop it."

Park Ji-hoon, who lived in 704 and had once spent forty minutes apologizing to Min-jae for a dripping air conditioner, pressed his back against the stairwell wall. He was in a bathrobe. He held a rice cooker lid like a shield. Min-jae had not asked why.

"It knows your name," Park whispered. "Min-jae-ssi, why does a crab know your name?"

"Because my father was careless with a pen."

Below them, the cavern breathed. Water slapped against concrete pillars furred with luminous coral. Lantern-jellyfish drifted through the dark, each one a small pale lamp, lighting the flooded parking garage in slow, shifting blue. A painted sign on the nearest pillar read B-13 in faded yellow. Someone had once been very proud of that parking spot.

The tollcrab stood at the foot of the stairs, shell the size of a delivery van, one claw raised in what Min-jae was increasingly sure was a *please proceed* gesture. Gold script still crawled over its carapace.

He took out his Ledger Seal. The brass coin was warm in his palm, like something recently alive.

"I'm going to read your contract," he said to the crab.

*"Honored guarantor,"* the tollcrab said. Its voice came as words floating up from the shell, slow and careful, each one set down like a cup on a saucer. *"This is… permitted. Please. Read."*

"You're very cooperative for something level six."

*"I am… in arrears."*

"Ah," Min-jae said. "That's different."

He stepped down. Park made a noise like a kettle.

"Stay there."

"I want to stay there. I want to be *so* there."

The golden threads were easier to read up close. Min-jae let his eyes unfocus the way he did at four in the morning with a spreadsheet, until the lines resolved into text. The contract unrolled in the air beside the crab, pale script on a pale page.

[CONTRACT: PASSAGE & GUARDIANSHIP, Gate B-13]

[Debtor: Tollcrab (Lesser Debtor). Creditor: SEO MIN-JAE (as guarantor of SEO GIL-SANG).]

[Principal: 1 (one) Passage, to be furnished upon request of the Guarantor.]

[Guardian Duty: The Debtor shall hold the stairwell and the first crossing against all trespassers.]

[Payment of Guardian Duty: Applied to accrued interest.]

[Accrued interest: 61 Tolls. Principal outstanding: 1 Passage.]

Min-jae read it once. Then he read it again, slower, with a finger moving along the air as if it were paper.

"Hm."

"Hm what?" Park called. "Is *hm* good? Please say hm is good."

"Hm is clerical." Min-jae didn't look away. "Your crab has been working here for two years. Every day it guards the stairs, and every day that guarding gets credited to interest. Not principal. The principal, the actual thing it owes, hasn't moved at all."

*"I… did not know this,"* the tollcrab said.

"Nobody tells the debtor that. It's the oldest trick in lending." He felt something unpleasant and familiar settle in his chest: the professional disgust of a man who has seen the same fraud in four different industries. "You could guard these stairs for a thousand years and still owe one passage. The interest keeps eating your work."

*"Then I am… never free."*

"Not under this wording, no."

The crab lowered its claw. The clack it made this time was quieter, a till closing for the night. It was strange to feel sorry for something the size of a van with a shell full of knives.

Min-jae made himself keep reading. The sorrow was not billable.

"Here," he murmured. "Clause four. *Passage may be furnished by the Debtor or by any party the Debtor designates, with the Guarantor's consent.*" He straightened. "That's a hole."

"A good hole?" Park asked.

"A hole is a hole. It means the principal can be paid in a form other than what the lender expected. If I'm the one owed passage, and I *consent* to the crab leading us across the cavern, that counts as furnishing it."

*"I would… lead you,"* the tollcrab said at once. *"Gladly."*

"Wait. Don't agree to anything out loud yet." Min-jae held up a hand. "You've been robbed by wording for two years. Don't start by saying *gladly* to the next person who reads you a paragraph."

The crab went still. Then, slowly, its eyestalks bent toward him in what he could only describe as respect.

*"That is… kind."*

"It's hygiene."

He thought it through. Simply accepting the guidance would pay the principal, but it would also cancel the crab's reason to exist in this contract. If the Passage was paid, the guardian duty clause might collapse, and a collapsed guardian was a monster with no leash. Or the System might treat the tollcrab as released and unpaid interest as outstanding. The 61 Tolls were still there. Some other creditor sat at the other end of that thick strand running into the water.

He needed a deal that paid down the interest *and* the principal, and he needed it witnessed.

"Park."

"No."

"I haven't said anything."

"You have the voice. It's the voice you used when you needed me to sign for your packages. It's the voice of a man about to ask for a favor."

"Technically," Min-jae said, "it's the voice of a man about to call one in."

Park closed his eyes.

Min-jae turned the Seal toward him. A golden thread ran between them, thin and slightly frayed, glowing a nervous yellow. He'd noticed it the moment the stairwell door slammed open behind him, and had been politely ignoring it, the way you ignore a bill you know the amount of.

[Debtor: PARK JI-HOON. Creditor: SEO MIN-JAE.]

[Obligation: One favor. Status: Unpaid.]

[Origin: Building security override, March. "I'll owe you one."]

"You said that," Min-jae said. "In March. When I let you into the building at 3 a.m. after you lost your key card and your dignity."

"I was *cold*."

"You said *I'll owe you one.* I wrote it down."

"You *wrote it down?*"

"I write everything down. It's a condition."

Park opened his eyes. His voice cracked. "What do you need? If it's holding the crab, I can't. I'm a pharmacist's assistant. My hands are for pill counting."

"I need a witness."

"That's all?"

"That's all. You stand there, you say *I witness*, and you do not scream." Min-jae looked at him over his glasses. "It's the easiest favor in the world."

"It doesn't feel like the easiest favor in the world. It feels like a trap in a nice hat."

"It's a trap with a clause that says it isn't."

Park laughed, a short unhappy bark. Then he sighed, and some of the fear went out of his shoulders, replaced by the tired dignity of a man who has always paid his bills late but never not at all.

"Fine. I owe you one. Do it."

Min-jae pressed the Seal toward the thread.

It was like pushing a coin into warm water. The brass rim wavered. A thin line of gold tightened between the two men, hummed once, and settled.

[Debt called in: PARK JI-HOON. Favor: Witness.]

[Debtor pays value in kind. Status: Active.]

Park's hand jerked. A faint gold line was etching itself across his palm. "Ow. Ow, it's *tingly*. Is it supposed to tingle?"

"Probably."

"*Probably?*"

"Hold still. This part is legal."

Min-jae drew a breath and spoke to the crab in the voice he used for client meetings, the one that made people straighten their ties.

"Tollcrab. I am Seo Min-jae, guarantor of Seo Gil-sang. I propose a new agreement, to be witnessed by Park Ji-hoon, with this Seal as notary. Do you wish to hear the terms?"

*"I… do."*

"Term one. You will guide the two of us across the flooded cavern of Gate B-13, by the safest route you know, to the far shore. This constitutes furnishing of the Passage under clause four, with my consent."

*"Yes."*

"Term two. In exchange, I, as creditor, will apply the value of that Passage not only to principal but to your accrued interest, at a rate of one Toll per step."

The crab's eyestalks shot upright. *"One… Toll per step?"*

"The route is, what, three hundred meters? That's roughly three hundred steps, depending on your leg count. Call it a fair weight." He kept his face blank, because his heart was doing something athletic. He had no idea whether the System would accept an invented exchange rate. But the System liked wording, and *at a rate of* was wording.

"Term three. The guardian duty is suspended for the duration of the crossing, and resumes afterward only as principal-bearing service. From now on, any day you guard this stair counts toward your principal first."

A long pause. The jellyfish drifted. A drip echoed against a pillar.

*"That,"* the tollcrab said, very softly, *"is not in the original."*

"No. It's a correction."

*"You are… allowed?"*

"I'm a Collector. I'm permitted to renegotiate debts I'm owed." He hoped that was true. "If this is wrong, I pay a fee. If it's right, you owe me less each day. I'd say that's a better arrangement than the one you've been working under."

The tollcrab stood motionless. Then, with great ceremony, it lowered its entire body until the edge of its shell scraped the concrete.

*"I accept."*

"Park."

"I witness!" Park blurted. "I witness! I witness the, the thing! The crab thing! Yes!"

"Thank you. That was nearly dignified."

Gold light flared from the Seal, sweeping across the air between the three of them. A page of pale script wrote itself out line by line, clean and tidy, in a handwriting Min-jae recognized as his own, which he found unsettling. Then it burned. Thin gold lines scorched across his palm, across Park's, across a glowing ring on the crab's claw.

[CONTRACT SEALED: Passage & Interest Reduction, Gate B-13.]

[Witness: Park Ji-hoon. Notary: Ledger Seal (basic).]

[Debtor: Tollcrab. Creditor: Seo Min-jae.]

[Skill acquired: Amend Terms (Lv. 1). Allows modification of an existing debt with the debtor's consent.]

[Insight +1. Leverage +1.]

Min-jae stared at the notification. *Amend Terms.* He hadn't planned that. He hoped the System hadn't either, because a system that handed out skills as a side effect of paperwork was a system with a loose accounting department.

He noted it in his head. *Free. Possibly not free.*

"That," Park said weakly, "was the most horrifying thing I've ever done, and I did a night shift during a flu outbreak."

"You did well."

"I feel like I signed my kidney away."

"You signed a witness line. Your kidney is unaffected." Min-jae paused. "Probably."

---

The crossing began slowly.

The tollcrab went first, its legs clicking on the concrete shelf at the edge of the flooded garage, where the water was shallow enough to wade. Min-jae followed, then Park, who held the rice cooker lid over his head for reasons no one questioned.

The water was cold and tasted faintly of salt and pennies. The luminous coral turned slowly as they passed, as if watching. Lantern-jellyfish bobbed above them, and each one trailed its own thin gold strand away into the dark.

Min-jae counted debts without meaning to. It was a habit. The jellyfish owed to the coral. The coral owed to something in the water. Everything owed. The whole cavern was a net of faint yellow lines, and the weight of it made his head ache.

[Toll paid: 1. Toll paid: 2. Toll paid: 3.]

The notifications ticked past at the edge of his vision like a taxi meter.

"It's counting each step," Park said, wading beside him. "Is that normal?"

"I invented the rate eleven minutes ago. Define normal."

*"I have not been this light in two years,"* the tollcrab said ahead of them, almost shy. *"Each step is… less."*

"It's called amortization."

*"It is a beautiful word."*

"It's a boring word, but it's yours now."

Park laughed in spite of himself, then went quiet, watching a jellyfish drift past his shoulder. "Min-jae-ssi. Can I ask something? You don't have to answer."

"You may ask. I may decline to answer. That's standard."

"Your dad. Did he ever mention this?" Park waved a hand at the cave, the crab, the water. "Any of it?"

"My father mentioned many things." Min-jae kept his eyes on the crab's shell. "Horse races. A business partner named Mr. Oh who didn't exist. A cousin in Daegu who did exist but wished he hadn't. He never mentioned a flooded parking garage or a guarantor clause."

"I'm sorry."

"Don't be. I've been paying his debts for two years. I'm very good at it." He adjusted his glasses. "It just used to be in won."

*"Honored guarantor,"* the tollcrab said gently, *"he spoke of you."*

Min-jae's steps faltered.

"What?"

*"When he came. Before the gates were… open. He walked here, when this place was only a garage. He said… there was a boy who read every page."* Its eyestalks swung back, politely averted. *"He said you would not like it. And that you would do it anyway."*

The water rippled around Min-jae's shins. For a moment he forgot the cold.

"When did he come here?"

*"Before. Before the count."*

"Before the gate opened. That's impossible. The gate opened tonight."

*"The gate opened tonight,"* the crab agreed. *"The contract did not."*

Park glanced between them. "I feel like I should be quieter."

"You should be exactly as you are," Min-jae said, and found that his own voice had gone thin. He forced it flat again. "Crab. What else did he say?"

*"I… do not remember. The words are… under the interest."*

Of course they were.

He filed the information in the place where he kept things that would hurt later. There was a lot of room in there. He walked on.

---

They were two-thirds across when the water stopped.

It did not still gradually. It simply ceased, as if someone had pressed pause on the whole cavern. The ripples flattened. The coral stopped turning. The lantern-jellyfish hung in the air, then sank gently to the surface and lay there like dropped lamps.

The sound went last. The drip, the slap of water, the click of the crab's legs, all draining away until Min-jae could hear only his own pulse and Park's breath.

"Why did everything stop?" Park whispered.

*"The count,"* said the tollcrab. Its voice had changed. The careful hesitation was gone, and in its place was something close to dread. *"It is… looking."*

"Looking at what?"

*"At the guarantor."*

Min-jae lifted his head.

Ahead of them the far shore waited, a pale shelf of concrete with a rusted pillar and a door. Behind them the stairwell was a small bright rectangle. Between, the water lay flat and black as a pool of ink, and beneath its surface something moved.

It was very large. It did not so much move as *reorganize*, the darkness folding over itself as if the whole cavern floor were a single sleeping thing turning in its sleep.

His Ledger sight flared without his asking. Every thread in the cavern flickered, then bent, all of them drawing together, pointing down.

And one rose.

It came up out of the black water like a rope pulled from a well: gold, but not the thin pale gold of Park's favor or the tidy strand of the crab's toll. This was thick as a man's wrist, heavy with script, and the script was moving, whole paragraphs of it sliding along its length too fast to read.

It rose out of the water, hung in the air, and turned toward him.

"Min-jae-ssi," Park said, very small. "That one's coming at you."

"I see it."

"Can you, I don't know, stamp it?"

"I don't think it's a debt anyone owes *me*."

The thread whipped forward.

Min-jae tried to step back. His heel found nothing, and the cold water pulled at his shoes. The thread looped once around his left wrist, as light as a ribbon and as final as a handcuff. Gold lines burned into his skin, a bracelet of script he could not read.

[Debtor: SEO MIN-JAE.]

[Creditor: ———]

[Principal: ———]

[Guarantor of: SEO GIL-SANG.]

[Status: Due.]

The thread tightened. Min-jae felt the pull through his arm, through his shoulder, a slow patient drag toward the black water and the enormous thing waiting beneath it.

It was not hurrying.

It did not need to.

The creditor's fields were blank, as if the System itself could not bring itself to write the name.

And far below, in the dark, something very large turned over and opened an eye.
