The Class C Gate in Sector 3 had been open for six days without a clearing team, which meant the mana pressure inside had been building for six days, and the creatures within had had six days to organize themselves into whatever defensive formations their instincts produced. The Association had posted a minimum party requirement of three B-rank Hunters and a recommended composition of five. The last team to attempt it, a quad of B-rankers with a C-rank support, had retreated with two injuries and a broken mana-shielding array.
Liu Yun walked into it alone at seven AM on a Tuesday.
He had a coffee. He had his short blade, still the same one, worn, familiar, and useful in the way of tools that are maintained rather than upgraded, and he had his army.
The Gate deposited him in a labyrinth.
Greek Mythology stratum. He could tell from the architecture immediately. The walls were marble, impossibly white against the constant amber-dark that all Underworld spaces shared, carved with bas-relief scenes of hunts and battles and the particular divine drama that ancient Greece had made its primary export. The corridors were wide enough for five people abreast and tall enough to accommodate something much larger than a person, which was probably the point.
The first thing that found him was a Chimera.
A true Chimera, not a Gate variant or a partial reconstruction, but the full mythological configuration: a lion's body, a goat's head protruding from the spine, a serpent for a tail, all of it the size of a medium truck and moving with the absolute conviction of a creature that had never encountered anything it couldn't kill. Its fire breath lit the marble corridor in orange and white, and the decorative relief panels on the walls cracked under the thermal stress.
Liu Yun watched it charge from forty meters and said:"Fenris."
The Fenrir Shadow erupted from the floor and the corridor was suddenly full. Fenris, even at sixty percent scale, occupied the entire width of the passage, its void-maw opening to receive the Chimera's fire and simply absorbing it. Void and fire, and void won. The Chimera hit Fenris at full charge and Fenris didn't move. The Chimera made a sound that no living thing should be able to make, and then Fenris closed its jaws and the sound stopped.
[CHIMERA DEFEATED - SHADOW EXTRACTION AVAILABLE]
Liu Yun extracted it without approaching, extending the ability at range, a refinement he had developed over the past three weeks. The Chimera's shadow joined the Register.
[SHADOW EXTRACTED: CHIMERA - MYTHOLOGY CLASS: GREEK - SHADOW-68]
He moved deeper into the labyrinth.
The Greek stratum was rich. In three hours he encountered and defeated, through Fenris and his organized shadow formations, two Minotaur variants, a Hydra cluster with nine heads, each a separate B-rank-equivalent threat, all reforming when severed until he had Fenris apply void-fire to the stumps simultaneously, a troupe of Harpy Screechers whose sonic attacks shattered marble in a ten-meter radius and proved entirely ineffective against shadow soldiers, and thirty-seven standard warrior undead of the Greek variety that fell before Shadow Crawlers in under two minutes.
Then he found the main chamber.
It was a throne room. Circular, enormous, its ceiling lost in amber-dark, its marble floor cracked from the weight of centuries. On the throne, a stone construction twelve feet tall, sat an Underworld Deity Fragment, the partial manifestation of a chthonic god, reduced to dungeon scale, its divine energy distributed to create and populate the entire labyrinth.
Its form was vaguely human and specifically terrible: twelve feet seated, draped in darkness that moved like fabric but was not, its face a smooth ivory mask with no features except two horizontal slits where eyes should be. Its aura, in Void Sight, was deep red edged with gold, the red of an Underworld creature, the gold of something that remembered what it had been before the Gates reduced it to a dungeon boss.
It looked at him.
"Shadow-born human," it said. Its voice came from everywhere in the room simultaneously. "You carry the dead with you. I can feel them."
"Forty-four of your dungeon's creatures are among them," Liu Yun said. "You felt them leave."
"Yes." The Deity Fragment's mask turned slightly, as if reading something in the air around him. "You are not what the gates normally produce. You are something older than the Hunter classification system."
"I'm going to extract you," Liu Yun said. "I'd prefer to do it without destroying the dungeon. Cooperating would be faster."
The Deity Fragment was silent for a moment.
"You genuinely believe you can extract a deity fragment," it said. Not a question.
"I extracted a Fenrir Echo. You're less than that."
Another silence. Then the Fragment laughed, a sound like a temple collapsing slowly, inevitable and almost musical.
"Extract me then, Shadow-born. But know that what you add to your Register is not merely a soldier. Some things, when they join the shadows, remember what they were."
It allowed the extraction.
The Fragment's shadow entered the Register, and the system generated a notification unlike any he had seen:
[EXTRAORDINARY SHADOW EXTRACTED: DEITY FRAGMENT - GREEK CHTHONIC - UNIT DESIGNATION: HERALD][NOTE: This unit has retained partial divine cognition. It is capable of communication, counsel, and independent strategic assessment. It is LOYAL but not silent.]
The dungeon dissolved around him, without its central source, the labyrinth lost coherence, the marble walls going translucent, then transparent, then gone, depositing him back at the Gate entrance with every core fragment the dungeon had generated.
The core yield alone was worth more than his last four months combined.
He sat on the grass outside the Gate entry point and allowed Herald, the Deity Fragment, to manifest partially in his shadow. It appeared as a face in the shadow-surface, ivory-masked, regarding him from two dimensions.
"What are you?" it asked.
"I'm still figuring that out," Liu Yun said.
"Then we have that in common," Herald said, and withdrew.
