The gate did not open into darkness.

  It opened into memory.

  The trio stepped into a vast chamber carved not from stone, but from time itself. Shelves rose endlessly, stacked with books whose titles shifted when unobserved. Relics floated midair, suspended in gentle orbits—broken crowns, rusted blades, fragments of tablets etched with half-forgotten scripts.

  Some hummed softly.

  Others felt… aware.

  “This is…” Eryn whispered, glasses fogging slightly. “A research center?”

  “A record hall,” Yava corrected. “A graveyard. A library. Depends on what you’ve come to do.”

  Kael swallowed. “Why do I feel like something here is staring at me?”

  “Because it is,” Yava muttered.

  "This place is huge, I wonder if it serves great food." said Borgas to everyone as his stomach started to growl.

  The air itself felt heavy—not oppressive, but watchful. As if every step added a line to an invisible ledger.

  Footsteps echoed.

  Not rushed. Not hesitant.

  Everyone was vigilant.

  From between towering shelves emerged a small figure clad in simple archaeologist’s clothing—long coat, fitted boots, sleeves marked with ink stains and dust that never fully washed out. Her appearance was unassuming, almost mundane.

  Until she lifted her eyes.

  Golden. Old. Tired in a way that had nothing to do with age.

  The relics stilled.

  The books quieted.

  Yava inclined his head.

  “Greetings, Z,” he said calmly. “I’ve returned. And I brought my disciples this time.”

  The girl stopped a few steps away and studied them one by one.

  “…Disciples?” she echoed.

  A pause.

  Then a faint, humorless smile.

  “Welcome back, Yava,” Z said softly.

  “Are you ready to settle your debt?”

  Somewhere deep within the archive, a page turned itself.

  Z walked past Yava without ceremony, circling the trio like a curator inspecting damaged exhibits.

  Royal Road is the home of this novel. Visit there to read the original and support the author.

  Her gaze lingered on Kael first.

  “Physically capable,” she said. “Strategically reckless. You waste potential by charging problems that require patience.”

  Kael opened his mouth. Then closed it. “…Fair enough.”

  She turned to Eryn.

  “Logical. Analytical. Exceptionally observant.”

  A pause.

  “You neglect your body. One disruption, one blind spot, and your calculations collapse.”

  Eryn frowned. “That’s not—”

  “…Inaccurate?” Z finished. “No. It is.”

  Finally, Borgas.

  She stopped.

  Looked longer.

  “…You are troublesome,” Z said.

  Borgas stiffened. “S-sorry?”

  “You are pure,” she continued flatly. “Which makes you dangerous. You will choose to save others even when it costs you everything. You will not notice until it is too late.”

  Borgas scratched his head. “…Is that bad?”

  Z didn’t answer.

  Z reached into a recess between the shelves.

  She did not summon anything.

  She unwrapped it.

  A scroll with tube cover that could be opened.

  She opened it, revealing an ancient scroll bound by pale silver rods. The material was not paper, not silk—something in between, worn smooth by time rather than use.

  When Z unfurled it across the table, the air changed.

  Not brighter.

  Deeper.

  The Blue Moon Map revealed itself.

  Lines emerged—not inked, but remembered. Continents formed as echoes rather than shapes. Paths glowed faintly where existence had passed too often. Places of stress pulsed like old bruises on reality’s skin.

  “This does not show where things are,” Z said quietly.

  “It shows where the world has been touched.”

  Kael leaned closer. “That’s… unsettling.”

  “It should be,” she replied.

  Yava did not argue.

  He reached into his sleeve and produced a book.

  Black cover. No ornamentation. Yellow alphabets etched into the surface—not glowing, not decorative. Functional. Absolute.

  The Dimension Ledger.

  When he placed it atop the scroll, the reaction was immediate.

  The scroll shuddered.

  Lines flared outward like veins finding a pulse. Threads twisted and overlapped, converging where the ledger’s weight pressed into the fabric of the world.

  Eryn inhaled sharply. “Those distortions—”

  “—are debts,” Z finished.

  Yava wiped his brow.

  “…It accumulated faster than expected.”

  Z did not look at him.

  “You borrowed spatial energy,” she said.

  “Space always remembers.”

  Z extended three fingers.

  “First,” she said, “a village swallowed by a folding corridor. No exit. No entry. Just… lost.”

  A second finger.

  “A trade route warped into a spiral. Bandits have learned to farm travelers.”

  A third.

  “A curtain of space isolating a settlement. Time passes unevenly inside.”

  Kael whistled softly. “That’s bad.”

  “That’s urgent,” Z replied.

  She folded her hands behind her back.

  “You will choose.”

  Eryn was already scribbling furiously.

  “The data’s incomplete,” he muttered. “Probabilistic overlays, temporal noise—this map isn’t omniscient.”

  Kael pointed at a glowing mark. “Can it show artifacts? Weapons? Armor?”

  Z stared at him.

  “…It can,” she said slowly, “but that is not—”

  Borgas raised his hand.

  “Um… can it show food?”

  Everyone froze.

  Borgas flushed. “I mean—if someone’s hungry in those places—”

  Z looked at him for a long moment.

  Then, unexpectedly, she looked away.

  “…Yes,” she said. “It can.”

  Night did not exist here.

  But time moved.

  Yava placed his hand flat on the map.

  “We’ll start with the village,” he said. “People first. Always.”

  Z nodded once.

  “Expected,” she said. “That is why I called you.”

  She turned and began walking back into the archive.

  “Fix what you broke, Divine Merchant,” she added. “And perhaps I will forgive the interest.”

  The trio exchanged glances.

  Kael cracked his knuckles. “So… adventure?”

  Eryn adjusted his glasses. “Correction. Damage control.”

  Borgas smiled. “Helping people.”

  Yava added, "... and training."

  Yava followed Z into the depths of history.

  Behind them, the Blue Moon Map continued to glow.

  The world was waiting to be repaired.

  But first, they needed some rest and preparation and also... some dinners.

  "Any job can't be done properly when you are hungry"
