Day two of Floor 7 began like the previous day.

Seven bells, permit desk, and the clerk who no longer paused while writing Floor 7 in his log. Evidently, one day was sufficient to make it mundane. I was impressed by this professional attitude of his.

Rin greeted us ahead of us once again. Mira was thirty seconds behind me. As usual, we performed our routine check of shortbow, crossbow, and blades and then entered through the rune ring.

We were greeted by the entry chamber in the same manner, the same warmer ambient lighting, the same artificially crafted stone and three corridors. There was no change in any of this. There were no fresh marks in the entry chamber or any signs of movement at the entrance of the corridors.

"Left corridor mapped. Center corridor today."

"Agreed," I replied.

Rin had already turned towards the center corridor.

The center corridor was slightly longer than the left before its first split — there were around ninety feet of straight passage, equal height of ceilings, and the same kind of artificially crafted stone. My UI remained silent. There were no partial tags or HP bars flashing up at me.

When she reached the first branch, she crouched down.

Marks on the floor. Not on the wall but on the floor, just as carefully and geometrically constructed as the wall marks from the previous day, but a different design. While the previous day’s wall marks had been created through a repetitive linear design, these were radial in nature — an outer circle with evenly spaced lines radiating out from its center, similar to a compass rose without directionals.

"Different design," I commented.

"Same cutting implement," Rin replied. "Same depth, same quality of edge."

"Different purpose," Mira noted. She was examining the branch corridor that the marks were placed in front of — the left branch, not the right. "It’s marking something. A direction, a location, a boundary."

"A warning or a guide," I guessed.

"Depends on more information."

PATTERN RECOGNITION II

Environmental note: Marks on floor at first branch junction — center corridor. Radial design, center circle, evenly spaced lines. Cutting tool identical to previous day’s wall marks. Marks at branch entrance — specific to left branch. Purpose unknown: directional indicator / location identifier / boundary caution. Insufficient information to determine actual purpose.

Conclusion: Don’t enter the marked branch until function has been established. Map the unmarked branch first.

"The right branch," I suggested.

Neither of them disagreed.

Forty feet long and it ended in a room.

Not a corridor chamber but a proper room — roughly square, twenty feet wide and tall like the corridors. It had markings on three out of four walls, all radial and just like the marking on the floor at the junction, all at about chest-level and equally deep and spaced.

In the middle of the room there was a unit.

Crouching on the floor instead of standing like the first one in the corridor, it seemed to be doing something with its hands. Like before, the UI tag was still partially displayed. HP bar visible, no number. Strength estimation in cycle with no conclusion yet.

It did not bother looking at us as we came in.

We stopped at the entrance. Rin reached for her blade but didn’t draw it. Mira was holding her crossbow with a bolt in it but wasn’t aiming. I drew the shortbow — Drew — and held.

The unit continued doing what it was doing.

"It senses our presence," Rin murmured.

"Yes," said Mira.

It knew. We’d picked up the subtle change in posture back on day one when it was introduced with a weapon — it had done the same thing today, but this time there was more. There was a subtle shift in its shoulders, which told us that it knew that we were here and had filed the information away before returning to what it was doing.

What it was doing, we could see now that our eyes had adjusted to the lighting in the room — it was drawing on the ground. Not the radial pattern. Something new, a series of smaller marks arranged in a loose grid, each one individual, no two identical.

"Field data," Mira said. "Just like us."

We sat there and let that sink in for a moment.

The unit completed the mark that it had been cutting into the floor, paused for a second, and then it looked up at us, just like on day one. Same sustained stare, same lack of hostility or fear, same tilt of the head — only this time after thirty seconds, not forty.

Learning curve.

PATTERN RECOGNITION II

Environmental note: Floor 7 unit — second contact. Engaged in floor marking, grid pattern, individual marks. Behavior continued after party entry — unit aware of party’s presence, chose to keep marking rather than approach or retreat. Head tilt observed at 30 seconds, down from 40 seconds on day one. Learning curve confirmed — unit updating behavioral data between contacts.

Conclusion: Unit is intelligent, observant, and recording. Purpose unknown. Threat assessment: UNCLEAR — no threatening behaviors displayed across two contacts, behavior indicates active assessment rather than combat orientation.

I held the draw. The unit regarded the shortbow. It regarded me. It regarded the shortbow once more.

Then it raised one hand, palm extended, using the exact posture which means stop or hold or don’t worry about me in almost all cultures who use the gesture.

"It just—" Rin began.

"Yes," I agreed.

"That’s a communication gesture," Mira observed. Flatly filing it away. "Universal. It understands the gesture or evolved it independently."

"Either of these answers is relevant," I stated.

The unit performed the gesture for five seconds before bringing its hand back down to continue with its marking process. It did not turn to face us again. It was leaving the decision up to us — leave or stay — it had no time for our questions.

I eased the tension off of the string. Kept the arrow. Did not fully lower the bow.

We stood in the doorway and watched it mark for four minutes.

It made eleven additional marks, one after the other, in the grid. Each mark took approximately fifteen seconds and each was unique. After the eleventh mark, it sat on its haunches and stared at the grid for several moments, then turned back towards us once more.

After that, it straightened itself up and stood to full height — reaching above the tallest person among us and seeming even larger due to its long limbs. Then, it moved across the room to stand near the far wall.

Offering us access to the markings.

"It wants us to see," Rin stated.

"Or it’s indifferent as to whether we see," Mira stated. "Its actions cannot be taken as intentional."

"We’ve established it isn’t impeding our progress," I stated.

I made my way across the room. Rin remained at the entrance, while Mira moved to my left, still holding the crossbow oriented toward the unit on the opposite wall.

I crouched down over the markings on the floor and examined them.

Close up, the markings revealed themselves to be more intricate than they had been from the distance of the room’s entrance — there was a distinct structure to each of the markings themselves, their consistency indicating a skilled and practiced hand, ones that could only come about as a result of fine motor skill honed over time. 𝑓𝓇𝘦ℯ𝘸𝘦𝑏𝓃𝑜𝘷ℯ𝑙.𝑐𝑜𝓂

There was meaning here. I just lacked the key to unlocking it.

I got up and went back to the doorway. The unit against the far wall stayed in place.

"Surface," I said.

"We only have two hours remaining in our permit," Rin told me.

"I know that." I studied the back of the unit. The grid marks on the floor. The radial marks on three walls. "That’s enough for us today."

Rin studied the unit. Then looked at me. Nodded once.

Then she led us back to the central passageway where we resurfaced through the rune ring.

---

The canal bench. Mira was ready with her notes as soon as we were seated.

"It was communicating with us through body language," said Rin, and she said it the same as anything else — straightforwardly, directly, past surprise and on to explanation.

"Confirmed cross-cultural gesture," said Mira. "Palm out, stop or wait. Correctly used."

"It’s been studying us," I said. "First day, it studied us, then retreated. Second day, it allowed us entry to the room, did what it came to do, and left us the marks."

"It’s creating a picture of us the same way that we’re creating a picture of it," said Mira.

"Field data," I said. "Just like us."

The water flowed beside us. To the east, a cart was being wheeled across the bridge.

"Gating hypothesis," said Rin. "If the EXP is behind a guardian kill, the guardian on this floor will not be a Shade encounter."

"No," I said. "It won’t be."

"And that alters the entire approach architecture," said Mira.

"And everything else too," I said.

I opened the wiki. The Floor 7 entry had been automatically updated based on our field data.

WIKI — POST-CANON ENTRY 005

Subject: Floor 7 unit — classification pending

Designation: UNKNOWN

Status: INSUFFICIENT DATA — field documentation ongoing / contact frequency increasing

Contact frequency increasing.

It had been identified by the wiki even before I had registered it consciously. Day one — contact, withdrawal. Day two — contact, communication, access provided.

It was escalating. In engagement, not aggression.

I didn’t know whether or not it needed something from this escalation yet.

"Tomorrow," Rin said.

"Tomorrow," I said.

Mira closed her notes. The wiki page filled part of my UI screen, richer than the one from yesterday but not complete — that was how things worked on Floor 7, more information than when we had begun but never enough to make a pattern clear.

The unit had given us access to its records.

I found myself wondering what it had made of ours.
