The Underbowl announced itself before the stairway ended.

  The sound built with each step downward, the compressed roar of a crowd with something to watch gaining detail and direction until it was no longer a sound but a presence, something felt as much as heard. The air changed too, warmer and closer, the smell of stone and lamp oil giving way to something more human, the smell of many people in an enclosed space sharing a concentrated experience.

  Then the stairway ended and the Underbowl opened up.

  It was enormous.

  Not in the way the Undercourse was enormous, not the spread-out enormous of a market that had grown into available space. This was intentional enormous, designed enormous, a space that had been excavated specifically to be this size for this purpose. The ceiling was high enough that the lamps suspended from it were small points of warm light at a distance, and the stone walls curved inward slightly at the top in the manner of something that had been built by people who understood acoustics and had applied that understanding.

  The arena was at the center and it was lowered.

  Not a stage, not a raised platform. A pit, roughly circular, its floor perhaps four meters below the level of the surrounding space, its walls stone and old and marked by evidence of the things that had happened against them over what appeared to be a considerable amount of time. The floor of the pit was clean in the way that things are cleaned regularly by people who have a professional relationship with the cleaning. Around the pit's edge, tiered viewing cut into the surrounding stone like steps for a god's amphitheater, and every tier was occupied.

  The crowd had the same mixed quality as the rest of the Undercourse — the Greyward's residents shoulder to shoulder with people whose equipment announced different origins — except here the mixing was more complete, the shared attention of the arena erasing the distinctions that mattered everywhere else. Everyone was watching the pit. Everyone was watching it with the specific quality of investment that came from having something at stake on the outcome.

  In the pit, two figures. One of them was still upright. The other was making progress toward being upright again from a position that suggested the progress would take a while.

  "Ladies and gentlemen of the Underbowl," said a voice.

  It was a good voice. The kind of voice that filled a space without effort, that found the acoustics of a room and worked with them rather than against them, that had been trained or naturally gifted into the specific register of a voice that a crowd listened to without deciding to.

  Aris knew that voice.

  He found the source of it at the far edge of the pit, on a platform that elevated the speaker enough to be seen from every tier. A man in a deep blue coat, broad-shouldered, somewhere in his forties, with the particular presence of someone who occupied public space as a professional matter. His hair was dark with grey at the temples and he held himself with the ease of someone who had been in front of crowds long enough to have stopped being aware of them as crowds and simply experienced them as the natural condition of being.

  "Our champion remains uncontested," the voice said, carrying to every tier without apparent effort. "The floor belongs, as it has for six consecutive months, to—"

  "That's," Aris said.

  "Yes," Kai said, moving through the crowd with his hand on Aris's shoulder, navigating toward the lower tiers.

  "That's Corven Ash," Aris said.

  "Yes," Kai said.

  "Corven Ash who does the morning announcements from the Guild Headquarters steps," Aris said. "Corven Ash who reads the dungeon conditions and the weather forecast and the merchant advisories every morning. That Corven Ash."

  "That Corven Ash," Kai confirmed.

  "He's been doing that since I was ten," Aris said. "He's—everyone knows who he is. He's a public institution."

  "He's also very good at his other job," Kai said.

  "His other job being," Aris said, looking at the man on the platform, who was now describing the merits of the fallen fighter with the warmth of someone who respected the craft regardless of the outcome.

  "This," Kai said simply.

  They pushed further through the crowd, Kai navigating by some internal map of the space, finding the gaps between people with the ease of practice. Colette moved behind Aris, her folded cape pressed to her side, her free hand occasionally redirecting people who were about to step backward into her with the light efficient touch of someone who had learned to move through difficult rooms.

  "How do we find one person in this," she said, looking at the tiers, at the crowd, at the hundreds of faces all oriented toward the pit.

  "We don't," Kai said. "We ask."

  He was already moving toward the edge of the pit, toward the platform where Corven Ash was delivering his verdict on the concluded fight with the rhetorical generosity of a man who understood that the losing side of any contest deserved dignity in the telling.

  "Kai," Aris said. "What are you—"

  A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

  Kai reached the platform's edge.

  "Ash," he said.

  Corven Ash looked down from his elevation with the measured attention of a man who was not accustomed to being interrupted mid-sentence and had developed a comprehensive policy about it. His eyes found Kai and ran the assessment that experienced people ran on unknown quantities.

  "One moment," he said to Kai, with the courtesy of someone who meant it. Then, to the crowd: "We'll take a brief pause before the next bout. Refresh your glasses, settle your wagers, and do not go anywhere because what's coming next will be worth every second of your patience."

  The crowd's response to this suggested they believed him.

  Ash stepped to the platform's edge and looked down at Kai with the focused attention of a man who had granted an interruption and expected it to justify itself.

  "Spell tracker," Kai said, at the volume of a conversation rather than an announcement. "Someone bought one from the Undercourse stock about twenty minutes ago and came down here. I need to find them."

  Ash looked at him for a moment.

  Then he looked at the group behind him. At Aris, at Elysse, at Colette with her cape folded over her arm, each of them receiving a second of the same measured assessment.

  Then he turned back to his crowd.

  "A brief inquiry for our audience," he said, and his voice filled the Underbowl again with the ease of breathing. "A spell tracker changed hands in the market above us not long ago. The new owner is somewhere in this room. If that person would be willing to make themselves known, there are parties interested in a conversation about the item."

  The crowd shifted.

  Not all of it. The shift moved through it the way a wind moves through a field, people looking at each other and then looking toward the source of the looking, the collective attention redistributing itself from the empty pit to the question that had just been placed in the room.

  Then someone stood.

  He stood in the way of people who have been standing in rooms their whole lives and have never questioned their right to occupy the space they stand in, which is a specific quality of standing that announces itself before the person is fully upright. From the third tier, center section. He rose to his full height and it was considerable, and he moved from his tier to the main floor with the unhurried deliberateness of someone who had decided where he was going and expected the path to clear accordingly.

  It did.

  He was tall, somewhere past fifty with the bearing of someone who had not allowed fifty to be a negotiation. Long grey hair, worn loose, catching the Underbowl's warm lamp light in the way of someone who had long ago accepted that their appearance communicated things and had made their peace with the communication. A black coat of arms, deep and well-made, the cut of something commissioned rather than purchased, with a house crest at the breast that Aris couldn't read from this distance.

  Colette could.

  He watched her recognize it. The specific stillness of recognition, the intake of something that wasn't breath, the recalibration happening behind her eyes in the second before her expression settled into the composed neutrality of someone who had put something away.

  "House Drent," she said, quietly, to herself as much as to anyone.

  The man reached the floor of the Underbowl and walked toward them, and as he came closer his eyes found Colette with the same quality of recognition moving through them.

  He stopped a few feet away.

  He looked at her with the expression of a man who had seen something unexpected and found it interesting.

  "Colette Aurel," he said. His voice had the register of someone accustomed to rooms where voices carried weight. "I had not anticipated finding an Aurel in the Underbowl."

  He said it with the courtesy of a gentleman, the particular courtesy that had been trained rather than felt, the kind that maintained its surface without committing to anything underneath.

  "Lord Drent," Colette said, with the same currency. "The surprise is mutual."

  "I come here occasionally," he said, with a slight inclination of his head toward the pit. "For the entertainment. It has a quality that the surface doesn't offer." He looked at her with the assessing quality of someone who had been in enough council chambers to read situations quickly. "The spell tracker. That's what you're here for."

  "It is," Colette said.

  "May I ask why."

  "A medical matter," Colette said. "Someone in my care requires it."

  Drent looked at her for a moment. Something moved through his expression that wasn't quite a smile and wasn't quite not.

  "Someone in your care," he said. "Still maintaining the captain's register, I see. Even after—" He paused, with the timing of someone who knew exactly when to pause. "Well. Recent events."

  The words landed with the precision of something that had been aimed.

  Colette said nothing. Her expression maintained itself with the thoroughness of three years of council chambers and formal guild functions, but Aris, standing beside her, saw what it cost.

  "I lost good people in that expedition," Drent continued, in the tone of someone offering sympathy and doing something else simultaneously. "Wanderers who had worked with your guild, who had trained in Aurel facilities. A terrible outcome. Truly." He looked at her. "One wonders what kind of captain sends fifty-three of her best into a Floor 46 descent and stays home."

  "Seventeen gold," Elysse said.

  Everyone looked at her.

  She was standing slightly forward from where she had been, her grey eyes on Drent with the direct quality they had for everything, the composed attention of someone who had assessed the situation and decided that a particular thread of it needed cutting.

  "That's what you paid for the tracker," she said. "How much do you want for it."

  Drent looked at her with the recalibrated attention of someone whose conversation had been redirected by an unexpected participant. His eyes moved across her armor, her bearing, the white hair, the quality of her even at diminished capacity.

  "You're one of hers," he said. "Aurelian Compact."

  "How much," Elysse said.

  He reached into his coat. The spell tracker came out in his hand, and up close it was exactly what it had looked like in the Veilmarket case, the gold casing and the dark needle and the sigil geometry worked into its surface with the precision of something made by someone who understood both its function and its craft.

  He held it in his palm and looked at it with the expression of someone considering something.

  "I intended it as a gift," he said. "For my party's navigator. A useful tool for deep floor work." He turned it in his hand. "I suppose I could acquire another through the Veilmarket." He looked at Aris. "I'd want seventeen gold for it. Given what I paid and the inconvenience."

  "Seventeen," Aris said.

  He said it with the specific expression of someone for whom seventeen and twenty occupied the same category of number, which was the category of numbers that bore no relationship to anything in his actual life.

  "That's—" he started.

  "Too much," Kai said flatly.

  Drent looked at Kai with the expression of someone who had noticed him and was deciding what category to place him in.

  "Too much," Drent said.

  "Considerably," Kai said.

  Drent looked at the tracker in his hand. Looked at the group. His expression moved through something private and arrived at the expression of a man who had just been presented with an entertaining idea.

  "What a shame," he said. "I suppose—"

  "What a wonderful problem," said Corven Ash.
