The Undermarket had no entrance.
That was the point. You didn't walk into the Shadow Trade — you were found by it. Kael had spent three days asking questions in the lower districts of Aethermere, dropping hints in the right taverns, mentioning the right names. By the third night, a note appeared under his dormitory door.
The Grey Candle. Midnight. Come alone.
He didn't come alone.
"You owe me for this," Ren muttered, pulling his hood lower as they navigated the rain-slicked alleys of the merchant quarter. "If Torvin finds out we're sneaking into the black market, he'll bench us for a month."
"Torvin wants answers about the dungeon tampering. This is where the answers are."
"And if the Shadow Trade doesn't appreciate visitors?"
Kael glanced at him. "Then you hold the door while I Void Step us out."
Ren grinned despite himself. "Fine. But you're buying breakfast after."
The Grey Candle was a decaying tavern at the end of a dead-end alley. Its sign hung crooked, the candle painted on it faded to a grey smudge. Inside, the air was thick with smoke and the sour smell of cheap ale. A handful of patrons sat in corners, faces hidden behind hoods and scarves.
Kael's Void Sense pulsed the moment he crossed the threshold. Faint — barely a whisper — but unmistakable. Void energy. Not from a dungeon, not from a rift. From something here. Something in this building.
He followed the feeling to the back of the tavern, past the bar, through a door marked Staff Only. The corridor beyond was narrow and poorly lit, ending at a heavy iron door with no handle.
The note had said to knock twice. Kael did.
The door opened from inside. A woman stood in the doorway — tall, lean, with dark skin and silver-streaked hair pulled back tight. Her eyes were sharp, calculating. She wore no weapons, but Kael's Appraisal read her as Level 28. Far too high for a tavern keeper.
"You're early," she said. Her voice was low, accented. "And you brought a friend."
"He stays outside," Kael said.
"Kael—" Ren started.
"Stay here. If I'm not back in twenty minutes, get Torvin."
Ren's jaw tightened, but he nodded. Kael stepped through the door.
The room beyond was not what he expected.
He'd imagined a back-alley operation — crates of stolen goods, desperate sellers, whispered deals. Instead, he found a showroom. Polished stone floors, soft lighting from mana-crystal lamps, glass display cases arranged in neat rows. It looked like a high-end shop. The kind of place where the wealthy bought things they didn't want the Hunter Accord to know about.
The woman — she hadn't given her name — led him down the center aisle. The display cases held items Kael had never seen before. Skill books with covers that shimmered in unnatural colors. Potions that glowed faintly in their vials. Accessories with stats he couldn't read — his Appraisal returned blank on several of them, as if the items were shielded.
"You're Kael Ashford," the woman said without looking back. "The orphan with the Mythic class. Word travels fast in the lower districts."
"I'm flattered."
"Don't be. You're not the first Voidwalker to walk through that door."
Kael's step faltered. He recovered quickly, but his Probability Eye had already caught the spike — her statement had a 92% chance of being true. She wasn't lying.
She stopped at the last display case. Inside, resting on a bed of dark velvet, was a crystalline orb the size of a fist. It pulsed with a faint purple light — the same color as the energy that surrounded Kael when he used Void Step.
"Dungeon Modifier," the woman said. "Model Seven. Inserts into any dungeon core and increases boss level by one to three ranks. Discreet, efficient, untraceable by standard System detection."
Kael stared at the orb. His Void Sense was screaming now — the energy radiating from the modifier was identical to his own. The same frequency, the same signature, the same source.
"This is Void energy," he said quietly.
"Sharp." The woman leaned against the display case. "Most buyers don't know that. They just want harder dungeons for better loot. But you — you can feel it, can't you? Your class resonates with it."
"How many of these have you sold?"
"That's not a question buyers ask."
"I'm not a buyer." Kael met her eyes. "I'm the person whose class energy you're selling."
The woman studied him for a long moment. Then she smiled — not warmly. "Come with me."
She led him through a second door, down a flight of stairs, into a basement laboratory. The air here was cold, sterile, smelling of alchemical reagents and ozone. Workbenches lined the walls, covered in tools, vials, and half-assembled devices. In the center of the room stood a pedestal with a larger version of the modifier orb — twice the size, pulsing brighter.
Three people worked at the benches. They didn't look up when Kael entered. Their hands moved with practiced precision, assembling smaller modifiers from components Kael couldn't identify.
"We've been operating for two years," the woman said. "Started small — information brokering, f*******n skill books. The modifiers came later. A client provided the technology. We manufacture and distribute."
"A client," Kael repeated. "Who?"
"Anonymous. Pays in advance. Sends specifications. We build." She gestured at the workbenches. "The Void energy is the key. It's the only thing that can interface with dungeon cores without triggering System alarms. Regular mana gets detected. Void energy doesn't. It's like the System was designed to ignore it."
Kael's mind raced. The dungeon tampering — Thornveil, Ember Rift, and probably dozens more — all done with these modifiers. All using the same energy as his class. And someone was providing that energy. Someone who understood Void mechanics better than anyone alive.
"I want to see the specifications," he said.
"You're not a client."
"I'm the only person in this building who can verify whether these things are safe. If they're unstable, if the Void energy bleeds into the dungeon core, people die. The Thornveil boss was two levels too high. The Ember Rift boss was one level above standard. Someone is testing the upper limits. How long before a modifier pushes a dungeon past its breaking point?"
The woman's smile faded. She looked at him — really looked — and for the first time, her expression showed something other than professional detachment.
"You know about the bleed," she said.
"I've seen the rifts. Artificial tears in the dungeon fabric. Someone is injecting Void energy through miniature portals and sealing them behind hidden walls. The modifiers aren't just changing boss levels — they're destabilizing the dungeons."
She was quiet for a moment. Then she reached into her coat and produced a folded piece of parchment. She handed it to Kael.
He unfolded it. It was a schematic — technical, detailed, written in a hand that was precise and clinical. At the top, a title: Project Nexus Gate — Phase 1: Dungeon Integration.
Below it, a list of specifications for the modifiers. Tolerance thresholds. Energy conversion rates. And at the bottom, a note in the same handwriting:
Test modifiers in D and C-rank dungeons. Monitor bleed rates. Phase 2 requires stable Void-dungeon interface. Proceed when bleed is below 0.3%.
Kael read it twice. His hands were steady, but his pulse was not.
"Phase 2," he said. "What's Phase 2?"
"I don't know. The client doesn't share the full picture. We're just the manufacturers." The woman took the schematic back. "But I'll tell you this — the orders have been increasing. Three months ago, we shipped ten modifiers a month. Now it's fifty. Whatever Phase 2 is, they're accelerating."
"Who else knows about this?"
"Our clients. A handful of guild leaders who buy modifiers for their own dungeon runs. The Hunter Accord suspects the Shadow Trade exists, but they don't know about the modifiers." She paused. "Until now. You know."
Kael met her gaze. Probability Eye calculated: chance she would try to silence him — 17%. Low, but not zero.
"I'm not here to shut you down," he said. "I'm here to find out who's behind this. The Void energy in these modifiers — it's the same as my class. Whoever is providing it knows things about the Void that nobody else does. I need to know who."
The woman studied him for another long moment. Then she reached into her coat again and produced a small card — black, featureless, with a single symbol embossed in silver: a broken circle.
"Take this to the Whispering Flask, three streets east. Ask for Maren. Tell her Selene sent you. She handles the supply chain — she might know where the Void energy comes from."
Kael took the card. It was cold to the touch, and his Void Sense pulsed once — the symbol was Void-touched.
"Why are you helping me?" he asked.
Selene — if that was her real name — turned back toward the stairs. "Because the last shipment of modifiers came back with a warning. The bleed rate is climbing. Whatever Phase 2 is, it's going to break something. And I don't want to be standing in the room when it does."
Kael found Ren waiting in the tavern, two empty mugs in front of him and a expression of poorly concealed anxiety.
"You were gone forty minutes," Ren said. "I was about two minutes from storming in."
"I found what we needed." Kael sat down across from him and lowered his voice. "The Shadow Trade is selling Dungeon Modifiers — items that use Void energy to change dungeon parameters. The same energy as my class."
Ren's eyes widened. "Someone is using your class energy to tamper with dungeons?"
"Not my energy specifically. But the same type. And someone is supplying it to them in bulk. There's a project — Nexus Gate. Phase 1 is dungeon integration. Phase 2 is unknown, but they're accelerating."
Ren leaned back. "This is bigger than we thought."
"It's bigger than anyone thought." Kael turned the black card over in his fingers. The broken circle symbol caught the lamplight. "We need to find out who's behind this. Before Phase 2 starts."
"Where do we go?"
"The Whispering Flask. Three streets east. Someone named Maren handles the supply chain."
Ren stood, dropping coins on the table for his drinks. "Then let's go."
"Not tonight." Kael pocketed the card. "It's almost dawn. We go tomorrow, when we're rested and I can keep Probability Eye active for longer. I want to know every angle before we walk into another room full of criminals."
Ren paused. "You think it's a trap?"
"I think the odds are 31% that Selene is setting us up, and 69% that she genuinely wants the bleed problem solved." He met Ren's eyes. "Either way, we go prepared."
They left the Grey Candle and walked back through the empty streets of Aethermere. The first light of dawn was creeping over the eastern walls, painting the stone in shades of gold and pink. Below the city, the Undermarket slept. But somewhere in its depths, someone was manufacturing tools that used the same power as Kael's class.
And somewhere else — someone was planning something worse.
The black card felt heavy in his pocket. The broken circle stared up at him like an unblinking eye.
Phase 2.
Whatever it was, he needed to find it before it found him.
