It was another four kills until I could map something worth mentioning.

The second one appeared at the next corner—same outline, same oddness in their shape, same lack of a user interface label. I looked at it for ten seconds before they started to move. It had the same assessment period as the first one. Same critical decision before making contact.

The third and fourth came in pairs—the first time seeing paired movement on Floor 6. It was completely different from the pairings on Floor 5. The voidwalkers on Floor 5 had acted in sync, in close proximity, with one acting as the distraction and the other as the flank. These ones moved separately, like they had awareness of each other but were independent. Parallel movements, distinct aggro target points.

Mira went for the left, I for the right, and we realized that the neck/shoulder junction was always a reliable kill point for all units. That was another observation.

The fifth one dropped from above. I realized it the moment **Combat Instinct I** activated—that readjustment at the base of your skull that you learn to take as a second opinion was worth paying attention to. My eyes had been trained on the path ahead. It came out of nowhere, from the blackness in the ceiling area. Combat Instinct had me running even as I recognized the sound. I rolled to the left. It landed right where I had been standing.

Mira’s bolt caught it as it was regaining its balance. I drew, held, and released. Then I got up and scanned the ceiling. No visual signs. No marker. No proximity sensors.

"The enemy uses vertical combat space," I explained.

"I noticed that too," Mira replied. She had already been staring upward. "Floor 5 didn’t go vertical."

"Not any floor below Floor 5."

**PATTERN RECOGNITION II**

**NEW DATA ON BEHAVIOR [UNCLASSIFIED]**

**Unit 5**

**ENGAGEMENT METHOD:** Vertical dive / ambush

**PRE-ENGAGEMENT PHASE:** No existence — no assessment stage

**CONCLUSION:** Protocol is not uniform across all units; variable engagement structure is established.

**RECOMMENDED:** Ceiling recognition for engagement protocol.

A variable engagement structure. It made Floor 6 fundamentally different from the other floors. The first five floors had been predictable. The Voidwalkers were consistent in their movement patterns and the Sentinels were consistent. Even the patrols on Floor 4 followed specific routes that were almost mechanical. All I needed to do was understand the pattern, use it to my advantage, and gather experience points.

That didn’t apply on Floor 6.

I took out the notational technique I’d been developing since the second kill and put it to work. There would be no automatic populating of the Wiki for me—I’d need to create all the data manually, one by one.

**FLOOR 6 UNITS**

**SELF-GENERATED FIELD DATA — [UNCLASSIFIED]**

**Unit classification:** Under review — provisional name **SHADE** until further notice

**Physical description:** Humanlike body shape / exaggerated physical attributes / lacks UI indicator / lacks HP bar

**Confirmed critical strike area:** Neck/shoulder connection (applies to Units 1–4)

**Unit 5 deviation:** Attack from above / lack of evaluation stage / ambush tactic

**Aggro characteristics:** Inconsistent — Units 1–4 exhibit evaluation phase / Unit 5 did not

**Pairing tendencies:** Units 3–4 use matching attack pattern / targets independently selected / does not coordinate

**EXP earned on kill:** None — applies to all five units

**System recognition:** None — does not classify creature / lacks death animation / does not dissipate

I reviewed the available data. A zero EXP return on five kills was the detail that stood out the most. Every other floor had awarded EXP on verified kills—even the most mundane Floor 1 mob had contributed something. The system would identify kills and pay appropriately. This was as core to the game’s mechanics as the dungeon entrance runes or the guild checkpoints.

But this floor wasn’t distributing EXP.

"The zero EXP is a reaction to your interaction with the system," I said. "Not a lack. An active response."

Mira analyzed the situation quietly. I saw the look in her eyes before she turned back to me.

"You think it’s gated."

"It might be. Everything under this floor has been a straight reward architecture, but everything above is hiding the rest behind tags, markers, and formations. Why would EXP be any different?"

"If it is gated," she answered slowly, "there must be a trigger condition."

"Yeah."

"Which would mean there’s something on this floor we haven’t discovered yet."

"Yeah."

There was a beat of silence.

"Maybe a boss structure," I suggested. "Gates EXP release upon guardian kill."

I remembered the guardian on the fifth floor—the one that required synchronized attacks before granting entry to Floor 6. Typical guardian setup for the floors below. But what if the floor above used the same principle, only concealed? All the EXP from these kills could be stored and released at once.

**PATTERN RECOGNITION II**

**Tested Hypothesis: EXP gating protocol**

**Test Data:** No visible reward from five verified kills / System silence / Information lockdown across floor

**Conclusions:** Inconclusive — Recommend further exploration

**Alert:** If hypothesis holds, guardian-type entity exists on sixth floor with considerable EXP reward upon kill.

Timing couldn’t have been better.

We descended further into the floor and I continued mapping as we went. The layout of Floor 6 was the most intricate yet. Meandering corridors, junctions, and forks that seemed deliberately complicated. While Floor 4 was a grid and Floor 5 a structured branching system, Floor 6 felt organic—like something that had grown rather than been built.

**Pattern Recognition II** kept hinting at geometry in the system. There was no randomness in the branches. Everything seemed oriented around a consistent center, like a spider’s web rather than a simple labyrinth.

Three more Shades showed up in the next passage. I had started calling them Shades without reservation—it was far more efficient than typing ’UNCLASSIFIED’ every time. Standard two on the ground, and one from above. Mira had already adjusted her positioning after Unit 5. Her bolt disrupted the vertical one before it could fully commit, and I finished it mid-air.

**Combat Instinct I** was being used more frequently with each engagement. The timing optimization was finally clicking in a way it never had on Floor 5. Floor 5 had been learned pattern recognition. Floor 6 demanded something more reactive.

Eight kills. Still no EXP.

The running tally stayed in the back of my mind like a debt.

We resurfaced four hours later. As we entered through the checkpoint, the clerk glanced up, noted our ranks and the time spent below, then jotted something down without comment. She had processed me this way forty times now.

"Any reports?" she asked.

"Different architecture," I responded. "Building a new data set."

She scribbled something else. "No EXP claims to file?"

"No."

That earned a brief pause in her writing. Zero EXP from both a B-rank and an Unclassified after four hours on Floor 6 was unusual enough to register, even for her. Still, she asked no follow-up questions. Professional.

Once outside, Mira fell into step beside me without a word. Dusk was settling over Ashveil. The market area was winding down, the Broken Crown two streets away, and the bench beside the canal stood deserted.

"Eight Shades," I said. "Zero EXP. Variable engagement protocols. Vertical ability confirmed. Likely geometric, central-point layout."

"And no wiki data to check anything against," Mira pointed out.

"And no wiki data."

Silence stretched across half a street.

"We are writing one of the first Floor 6 field reports."

"Yeah."

"It will have some value when other B-ranks try their luck on it."

I hadn’t considered that angle before. The wiki had always been a source of pre-existing information. Creating something myself felt strange.

"Now we need to focus on our task," I announced. "We should discover what is located in the heart of this network."

"The guardian?"

"In case our theory proves correct."

"I am sure about that," Mira stated. No pride, just cold calculation.

I didn’t object.

Eight killed monsters without a single trace of experience on the scoreboard. Somewhere in this organic, curved floor structure, something waited. The system had shared nothing about it.

And I could hardly wait to find it.
