The Ashfen Rift entrance was not what Haruki had expected.
He wasn't sure what he had expected exactly - something dramatic, probably. Something that announced itself. A crack in the earth with visible danger radiating from it, or a gate with warning signs, or at minimum something that looked like it deserved the weight that people put behind the word dungeon.
What it actually was: a stone archway.
Old. Very old - older than the fort nearby, older than the road leading to it, older than anything else in the visible landscape. The stone was a different color from the local geology, darker and finer-grained, and it had been carved once with markings that time had worn to suggestions. It stood in the earth like it had grown there, slightly crooked, framing a darkness that was not the darkness of a cave or a tunnel but something with more intention to it.
The darkness didn't go anywhere visible.
It simply was, contained within the archway's frame, a rectangle of black that the morning light declined to enter.
Haruki stood at the back of the party's formation - porter position, correct distance behind the combat line, carrying frame settled and balanced - and looked at it.
"Sol," he said quietly.
"I see it," Sol said.
"The stonework."
"Yes."
"It's the same as the ruins in the Grey."
A pause.
Not a processing pause. A considered one.
"The geological composition is consistent," Sol said carefully. "The carving technique - what remains of it - matches the boundary civilization markers you documented in the Grey." Another pause. "I would prefer not to speculate beyond that until I have more data."
"But."
"But I am noting it," Sol said. "I am noting it very carefully."
"Rax," Haruki said.
"Yeah," Rax said.
Just that. No volume. No enthusiasm.
Which was, in its own way, louder than anything Rax had said at full volume since they'd met.
"You feel it too," Haruki said.
"Something's in there," Rax said. "Not on the surface floors. Deep. I can't read it clearly - it's like trying to hear something through water. But it's there."
"What kind of something."
"Don't know yet." A pause. "Old. Whatever it is, it's very old."
Haruki looked at the archway.
Maren raised her hand - the signal he'd been shown that morning during the ten-minute formation briefing that she ran with the efficiency of someone who had done it many times and saw no reason to make it longer than necessary.
Forward. Stay tight. Watch the line.
They walked into the dark.
The dark lasted approximately four seconds.
On the other side of the archway the dungeon opened into something that the word cave didn't quite cover - a space with the dimensions of a cathedral, ceiling lost in shadow above, floor stretching wide and level in a way that natural cave formations didn't achieve. The walls had the same dark stone as the archway, and they glowed, faintly, with a blue-white luminescence that came from within the rock itself rather than from any external source.
It was enough light to see by. Comfortably enough, which felt deliberate.
"Mana crystallization in the stone," Sol said, back to his reporting voice - the comfortable familiar one. "Standard dungeon luminescence. The mana density here is significantly higher than the surface but within normal parameters for a floor one classification."
"Feels different from the Grey," Haruki said.
"Completely different mana type. The Grey was cancellation - Order and Chaos negating each other. This is—" Sol paused. "This is something else. Neither Order nor Chaos exactly. Something older than the classification system."
"You keep saying old."
"Because the data keeps saying old," Sol said. "I'm reporting accurately."
The party spread into their formation - Cas at the front, shield up as a matter of habit rather than immediate necessity. Maren and Fen flanking, mid-range. Sable at the edge of the formation where the shadows were deepest, which seemed to be where she was most comfortable. Haruki at the rear, behind the line, where he could see all of them and the space behind without being in anyone's way.
Wick fell into position beside Haruki with the ease of someone who had done this many times, one-handed carrying frame and all.
Floor one was large and mostly flat and full of slimes.
Slimes, it turned out, were exactly what they sounded like.
Roughly spherical. Translucent, with a faint blue tint that matched the dungeon's luminescence. About the size of a large melon. They moved slowly across the floor in the unhurried way of something that had no natural predators and had therefore never developed urgency as a survival trait.
They made a sound when they moved. A small wet shifting sound. The sound of something that was entirely comfortable being what it was.
Haruki watched Cas dispatch three of them in the time it took him to finish that thought. One strike each, clean, the shield coming down and the sword coming across, and the slimes dissolved into a puddle of translucent liquid that immediately began to solidify at the center into a small blue crystal.
"Monster core," Sol noted. "Condensed mana. Two to three copper each at the guild desk. The liquid residue is also collectible - it has alchemical applications, low grade, but Fen appears to be bottling it."
Fen was indeed bottling it, with the focused efficiency of someone who had learned that the things other people ignored were often the things that added up.
Haruki watched and filed everything away.
The formation moved through floor one at a steady pace. Not rushed. Not slow. The pace of experienced people doing a job they knew well, recovering their rhythm after a disruption.
Haruki carried. Moved when the formation moved. Stopped when it stopped. Collected the cores that Wick passed back - Wick had developed a one-handed collection technique that was faster than it had any right to be, involving a specific wrist motion that Haruki watched twice and understood was something Wick had spent time developing privately - and packed them into the collection pouches in the carrying frame with the organization he'd set up that morning.
Left pouch: cores by size. Right pouch: liquid residue bottles. Center: party equipment overflow. Weight distributed for his center of gravity, not the frame's default.
"You reorganized the entire carrying system this morning," Rax observed.
"The default arrangement put too much weight high," Haruki said. "Stairs would have been a problem."
"There are stairs between floors," Sol confirmed. "You were correct."
"How did you know there would be stairs," Rax said.
"There are always stairs," Haruki said. "Every building has stairs. Why would a dungeon be different."
A pause.
"...That is," Sol said, "somehow both completely obvious and something I didn't think to model."
They found the first vein of ore on the eastern wall of floor one's third chamber.
Fen spotted it - the mage had a detection spell running at low level that manifested as a faint shimmer at the edge of his vision, and he raised his hand and the formation stopped and he pointed.
The ore was embedded in the wall in a natural seam, dark against the luminescent stone, catching the blue-white light in a way that was visibly different from the surrounding rock. Maren looked at it, looked at Haruki, and made the gesture she'd shown him that morning that meant your job now.
He unclipped the mining tool from the carrying frame - a short pick, balanced for one-handed use - and went to the wall.
Mining, it turned out, was less different from the rough metalwork his grandmother's friend had taught him than he would have expected. The principle was the same - read the material, find the grain, work with the structure rather than against it. Hit the right place with the right angle and the material cooperated. Hit it wrong and you worked twice as hard for half the result.
He worked the seam for eight minutes. Came away with a solid collection of ore chunks that Sol identified as mid-grade mana iron, worth considerably more than the slime cores.
Fen looked at the collection, looked at the wall, looked at Haruki.
"You left the seam intact," Fen said.
"It'll regenerate," Haruki said. "If you take the whole seam it has to rebuild from nothing. If you leave the structure it grows back faster."
Fen looked at him for a moment with the expression of someone who had just been told something that was obvious in retrospect and hadn't occurred to him before.
He wrote something in the small notebook he kept in his left breast pocket.
Haruki went back to his position in the formation.
Floor one took three hours.
By the end of it the collection pouches were satisfyingly heavy and the party had found a rhythm that was easier than the morning's start - the specific ease that comes from a group remembering how to be a group.
The stairs between floor one and floor two were stone, wide, carved with the same ancient markings as the archway outside. Haruki ran his hand along the wall as they descended, not quite touching the carved lines.
The same stonework.
The same civilization.
"Sol," he said, very quietly, too quiet for anyone in the party to hear.
"I know," Sol said.
"This dungeon was built by them."
"I believe so," Sol said. "Yes."
"The boundary civilization."
"The markings are consistent. The mana composition is consistent. The architectural principles-" Sol paused. "Yes. I believe this dungeon predates the current era of Aethermoor by several centuries at minimum. Whatever it was built for, it was not built as an adventurer's resource."
"What was it built for," Haruki said.
Silence.
Not the silence of Sol not knowing.
The silence of Sol knowing and choosing his words.
"I don't have enough data yet," Sol said finally. "I need the deeper floors."
"We're not going to the deeper floors."
"I know."
"We're going to floor two."
"I know, Haruki."
"Floor two has goblins."
"Yes."
"I'm going to carry bags on floor two."
"Yes."
A pause.
"Sol," Haruki said.
"Yes."
"Whatever is in the deep floors."
"Yes."
"It can wait."
Sol was quiet for a moment.
"...Of course," he said.
But Rax, who had been silent since the archway, said nothing at all.
And somehow that said everything.
Floor two opened ahead of them - wider than the first, the luminescence slightly warmer in color, the ceiling lower.
The goblins registered immediately. Small shapes at the edge of the light. Dark eyes catching the blue-white glow. A chittering sound that the dungeon's acoustics carried in ways that made it hard to locate precisely.
Maren raised her hand again.
The formation tightened.
Haruki settled the carrying frame, checked the pouches were secured, and watched the shadows where the goblins were and where they weren't, because his grandmother had told him once that you learn more from what's missing than from what's there.
Something in the deep floors, Rax had said.
Old, Sol had said.
Floor two's goblins began to move.
Haruki watched the formation do its work and carried what needed carrying and said nothing about the archway's stonework or the ore seam's grain or the thing that both systems had felt and neither had named yet.
One floor at a time.
That was the plan.
That had always been the plan.
To Be Continued....
