Rin was ahead of us at the Undercroft entryway.

Not by much — she was there waiting for us when we rounded the corner and saw a grey sky; she was there standing back against the wall by the checkpoint booth, two short hilts of blades showing on each shoulder, eyeing us like she did yesterday out in the corridor. Relationship status seven. No change since last night.

She made the marks on our manifest with no comment whatsoever, as usual. Party size three, lead class B, secondary class B, unclassified third. Three checkmarks, a gesture, and off we went.

No one said a word during our descent.

As always, the geometry of Floor 6 greeted us the same old way — wide corridor, high ceiling with no illumination, no proximity markers, no dungeon populace. The silent silence, not because there was nothing to hear, but because you knew there should have been something to hear. I’ve been down here often enough that my brain no longer registered the abnormal as abnormal.

Rin absorbed it all with a glance.

"We combine the maps and the center chamber will be four junctions along the left branch at the third main fork," I stated, careful to keep my tone down. "We have been doing the right branch attack run. The data on your maps matches at two junctions — both are confirmed identical."

"Understood," Rin replied.

"Shade engagement protocol — standard attack sequence, give me and Mira our range window before engaging. Vertical descent and your lead interception, we’ll adjust fire. Parallel pair formation, take the closest one, we’ll engage the further one in order."

Rin looked at me. "That was worked out before I got here."

"Last night."

There was something in her face. Not quite approval, not quite disapproval, both adjacent to each other. "All right then."

Mira’s crossbow was at the perfect position of not yet raised. Rin’s two blades were still sheathed and she moved in the fluid motion of one who knew that raising weapons too soon would cost more than they saved. My arrow was drawn but not yet launched.

We moved forward.

The first Shade appeared after the second turn in the corridor — the standard procedure of approach, assessment stage, and the usual decision-making process of the patient prior to engaging. I took the shot from the range position before it could complete its assessment phase. I drew. I held. I released. Junction shot, clean kill.

Rin watched me shoot without making any comments.

"Clean shot," she told me.

"The junction shot always hits."

"I know. The other shots aren’t so clean," she commented plainly, not using any derogatory terms about herself. "The neck junction is easier to hit with a bow than with a sword."

"And what is your objective when engaged in close combat?"

"A throat when I am able to get into that position; ribs when I cannot. Both shots are not as clean as your shots; they take some time to take the enemy down."

I stored that information. There was something to be considered regarding the time taken by my ranged shots to neutralize the target as opposed to the close combat shots.

They formed up parallel to each other, as we had talked about, coming into the formation from the left branch at a junction between them, two different targets, both operating independently.

Rin moved left, and I followed with my right.

The bolt from Mira nailed the right side in the upper body area, and I drew. I held. I released. Junction shot, clean kill. To the left, I got to see Rin close the distance with her target, all in three quick steps.

She was fast. More than her STR-primary profile would suggest, in fact; she was using her AGI-secondary more effectively than the numbers indicated. She closed the gap in her step sequence, before the Shade completed its assessment stage, and then took it in the throat with the first strike, missing the spot but not the intent due to its unusual dimensions. She rotated it with the momentum of her attack and got the second stab in through the junction point.

More messy than my shot. That much, at least, had been true. The Shade had fallen in less than four seconds and she hadn’t even gotten hit.

"Throat targeting doesn’t translate on these," I pointed out.

"I understand now." She stood tall. Not a trace of frustration. "The dimensions aren’t the same. The junction is vulnerable if you can get the rotations started from below."

"Update it in the field data."

SELF-GENERATED FIELD DATA UPDATE — SHADE CLOSE RANGE

Melee engagement details: humanoid throat targeting technique unreliable — dimensional discrepancy

New close-range tactic: rotate target by shoulder pressure / junction exposure from below

Time-to-kill: slower than ranged junction shot / reliable once rotated

Source of data: Rin — B-rank melee, Strength 71

Mira had been watching Rin operate with the same concentrated interest she brought to anything worth studying. "You were able to adjust during combat," she observed.

"The first target tells you what the second one needs," Rin observed. "If you’re listening."

"Indeed," Mira responded, almost confirming Rin’s observation before it was made.

The interaction of these two people was very intriguing to observe. They were not showing any kind of warmth towards one another — both of them seemed to lack the capacity for doing so, as far as Mira went, and obviously Rin did too — but there was something about their interaction, as well, an exchange of understanding that occurred whenever they communicated.

RIN — STATUS

Relationship / Kai: 11

Relationship / Mira: 9

Corruption meter: 4/100

Mood: Focused / Engaged

Note: Combat dynamic established — organic establishment process continuing

Four points above Kai, five points above Mira. Combat did that; it established relationships quickly because combat was harder to fake than conversation. Combat was about what you really were, what your decision-making processes were, how your mind worked in real-time under pressure. Rin saw me put two good shots together in sequence, and I saw her make adjustments during combat.

And still no change on the corruption meter. Four.

We ventured further.

The third junction would be where the floor began revealing itself to us in terms of the geometry of its web. These passages were not any more expansive than the first two we had seen, but they seemed less like an effort to misdirect and more like an attempt to funnel us toward something.

Pattern Recognition II was continuing without incident.

PATTERN RECOGNITION II

Corridor geometry analysis — junction 3 and beyond

Directional bias: verified, gradient increase

Funneling structure: in effect — passive directional guidance toward center point

Note: The design of the sixth-floor plan is not simply obfuscating; it is also leading somewhere. There is some sort of force emanating from the center point and forming the geometry surrounding it.

Forming the geometry surrounding it. This was a new reading. I had assumed that the design of the web was one of deliberate confusion, a means of obscuring navigation. Now, Pattern Recognition II was detecting a pattern of activity in the structure of the floor itself.

No wiki data for comparison. Filed as high priority unknown.

Fourth Shade approached from above.

Rin acted ahead of me.

It wasn’t because her Combat Instinct was faster — I wasn’t sure if she had the ability, after all — but because her stance had been adjusted for a ceiling approach since the first junction. Her weight had been slightly forward, and her vision sweeping to include the overhead dark from the very beginning.

Drawing twin blades, she took out the approaching Shade as it descended — not delivering a killing blow, deflecting it, holding her blade horizontally as the Shade fell into the strike. The result was that the Shade impacted the wall opposite, rather than hitting the floor. Mira was ready to deliver an attack when it rebounded; the junction shot went off as soon as it registered impact.

Three-man coordination during a vertical descent. Time from arrival to destruction — less than two seconds.

"That’s our quickest vertical yet," Mira commented.

"Deflecting is more efficient than dodging," Rin noted.

"Can you teach that?" I asked.

She stared at me. "I can show you how to angle the blade. As for whether you can accomplish it while holding a bow, that’s another story."

"Agreed."

It was the fourth fork — the last one before entering the central room based on the fused map — and we stopped there.

The tunnel was different now.

In no way that I could ever have articulated precisely. Same rough-hewn stone construction, same tall ceilings, same lack of illumination sources which would have made the path too dark to navigate except that Floor 6 maintained its unique ambient conditions. It was the geometry that was altered somehow. The funneling pattern that Pattern Recognition II had detected reached its peak in this stretch — everything angled forward, the walls bending inward, the path tapering slightly and in a deliberate fashion.

Then there were the Shades.

Three of them. Positioning themselves at the mouth of the fork, a cluster arrangement never previously recorded — not two parallel arrangements, not sequential, some other formation. All three in their evaluation phase, all three staring back at us.

"That’s novel," I whispered.

"Triple cluster," Rin whispered. "This happens sometimes. Approach route from the south, two junctions back. It has a completely different formation to any encountered on the eastern entry point."

"What happened?"

"I got out of there," she answered bluntly. "Three assessment phases running concurrently means three simultaneous engagement decisions. Not all on the same schedule, but they make the decision at the same time. And if you aren’t ready for it when they engage, you have to deal with three separate threats."

I examined the formation. Three Shades, three running assessments. The pass had narrowed sufficiently to remove their standard range advantage; there was no room to keep distance or to allow Rin room to run between close-range enemies.

"Center," Rin whispered. "You two get the outer positions on either side of center. Once those assessment windows break open, the one in the center goes to me while the others break towards range."

Simple. This she had already considered. Probably as soon as she mentioned the formation.

"Agreed," Mira whispered.

"Agreed," I whispered.

Our formations were set. Rin at the front center position. Mira on her left at the maximum crossbow range. Myself on her right, arrow drawn.

The three assessments each lasted eight seconds, more time than any of the single Shades I had assessed thus far, as if their cluster formation extended the decision time period, calculating in unison prior to committing to an action.

Then they broke.

Center Shade assessed Rin. Left and right Shades assessed and approached independently — parallel approach, identical formation structure as the two-Shade cluster except tripled.

I drew. I held. I released. Right Shade, junction shot, clean kill before it even got halfway.

Left Shade was assessed and shot by Mira with a direct hit to its upper body. It faltered, her second bolt being loaded; she fired again and nailed the junction with her second shot.

Rin and the central Shade were in close proximity. She allowed it to initiate contact with her. This differed from how she handled the dual-Shade formation, being completely passive during approach. She used the commitment angle to rotate the Shade into position where her second blade attacked the junction.

Down.

Silence in corridor.

Total time of engagement: Three seconds.

EXP notification: Zero across all three Shades.

"Tab’s getting heavy," Rin noted, glancing at the spot where the center Shade had fallen.

"Yeah," I replied. "The payout in the center chamber is gonna be worth it."

Rin glanced down the hallway. Funneling was at its greatest here — everything funneling in front of her. The center chamber was closer now, and even without the map data, I knew it pulled in my direction.

"Tomorrow," she declared. "We spend today mapping the final junction and enter with refreshed energy."

Right. It was better to come fresh to a guardian-class entity with a triple Shade formation guarding it.

"Tomorrow," I echoed.

Mira made no reply; she was already writing notes on the triple Shade formation pattern. We came up forty minutes later and the clerk logged our return. Zero EXP gained. No questions asked about that either.

Back outside, Rin walked alongside us until we hit the street. Then, she turned off and went who knew where. No lingering chat. No pleasantries. Just a nod as she passed by.

"She’s integrating quickly," Mira said, after Rin had left us.

"Combat makes you integrate," I said.

"Yes, combat does," she agreed.

RIN — STATUS

Relationship / Kai: 19

Relationship / Mira: 17

Corruption meter: 4/100

Mood: Focused / Settled

Note: Combat trust established — organic establishment phase accelerating

Nineteen. Rising from seven in just one session. This meter was ticking over as it was supposed to — on the basis of skill, of shared risk, of tactical exchange. No mechanics working behind the scenes. No warning signals, no corruption approach, no created tension.

Just three players figuring out how to work together to win battles in an area the developers never meant for anyone to pass.
