Yuna had drawn a diagram.
Not a rough sketch. A proper floor plan — corridor section, hazard markers, climber cluster positions, estimated patrol patterns. All from a starter kit notebook and one mechanical pencil.
In the center was a blank box labeled: GUARDIAN (UNKNOWN)
She tapped it.
"This is what we need to fill in."
"I'll handle that part," I said.
She gave me the look she had been developing specifically for sentences like that one.
"You'll handle it," she said. "By dying."
"By dying efficiently. There's a difference."
"There genuinely isn't."
The problem wasn't that the Guardian was strong.
Every Floor Guardian was strong. That was baked into the Tower's architecture — expected, standard, survivable with enough preparation and climbers who knew what they were walking into.
The problem was nobody knew how it killed.
Seven failed attempts. Seven groups who had walked into that corridor and come back at 34% capacity. The survivors had seen the aftermath — the dead, the retreat, the Guardian still standing — but not the mechanics. You don't study attack patterns while you're running. The dead couldn't report back. And nobody had thought to learn the fight from the inside before committing sixty lives to it.
"Seven attempts," I said. "No surviving accounts of the actual fight. Which means—"
"Everyone in this safe zone arrived after the last attempt failed," Yuna said, pencil moving. "Nobody here has seen it fight."
"Except in about twenty minutes."
She looked at the blank box.
"Several times," I added. "Possibly many."
She wrote something in the margin, angled away. I read it upside down — a skill the Tower had never needed to give me.
He is going to get himself killed.
Below that: That's fine. He'll come back.
Below that: I hate this.
She capped the pencil.
"When do we leave?" she said.
The Guardian's territory started at a wide corridor two hundred meters past a bend, where the stone opened up and the ceiling doubled in height.
It wasn't patrolling. It wasn't searching.
It was waiting — the way something waits when it has never needed to go looking because things always come to it eventually.
We arrived before sunrise.
Yuna stood at the territory marker with the notebook open and pencil ready. She had made me describe everything before each water death and everything I remembered coming back. Same for the cave-in. She was systematic about it in a way that I suspected was holding something else at bay. I hadn't commented on that. She hadn't either.
"Ready?" she said.
"No," I said. Honest answer.
I walked in anyway.
It was large.
That was all I managed before it was fast.
> Death #8 — Guardian (first contact) — Revived
> Cause: Unknown — impact, likely blunt
> Skills: None
> +10yrs — Total: 140 Years
> Notes: Contact duration before death: approximately 1 second. Visual: large. Speed: faster than the Warchief. Attack origin: unclear.
"Size?" Yuna asked.
"Big." I was sitting on the stone outside the marker running the inventory of being alive. "Fast. Didn't see the attack."
"Useful," she said, in the tone of someone for whom it was not yet useful.
"Give me a moment."
"Take two. Then go again."
I took two. Then I went again.
Death #9 gave me geometry.
I went in watching movement rather than size, tracking from the periphery, and got three full seconds before the attack connected. Stone limb — or stone-like, dense and grey, part of the creature rather than wielded — sweeping horizontal at chest height. Four meters of reach. Fast on initiation, clear deceleration on the recovery arc.
I lay on the cold stone afterward and ran the math. A notification ticked in — *Stone Resistance F, acquired* — and I filed it without stopping.
"Jump or duck?" Yuna asked when I came back.
"Jump. Duck gets your head taken off on the backswing."
She wrote: Jump. Do NOT duck. Underlined it twice.
"Anything else?"
"I think there's a follow-up. I didn't—"
"Go find out."
***
There was a follow-up attack.
I would like to formally note that I did not expect it.
> Death #10 — Guardian (jump tested, follow-up discovered) — Revived*
> Cause: Follow-up strike — overhead, fast
> Skills: None
> +10yrs — Total: 160 Years
> Notes: Sequence confirmed — sweep, then overhead follow-up. The overhead is faster than the sweep. Jumping the sweep puts you in the air directly for the follow-up, which he described as "sub-optimal." I've started writing down his exact words because the clinical detachment is either a coping mechanism or a personality trait and I cannot tell which.
Death #11 was the one that mattered.
I knew the sequence now — sweep, overhead follow-up, brief stillness before reset. What I didn't know was whether the stillness was long enough. Whether a climber who survived both attacks could do anything useful in that window before the next cycle.
I went in to test it.
The window existed. Barely. I died anyway — a third element I hadn't catalogued yet. Close-range strike inside the window, shorter reach than the sweep, faster than anything else it did.
I came back. Lay still. Ran the full sequence in order.
Sweep. Overhead. Close-range interrupt if you enter a certain radius. Then reset.
The interrupt had a tell. A weight shift, half a second, repositioning of the stone limb before it came across.
Half a second was enough.
The notification arrived while I was still processing.

I read the second skill description three times.
You have died to this entity.
Not studied. Not observed. Died to it, specifically. Like the Tower had a category for that. Like it had been prepared for this possibility before I arrived.
Like it had known I was coming.
I sat on the stone in the pre-dawn dark and thought about a system that had a skill built and waiting for dying to specific entities. That had constructed one for me in advance.
I filed that under think about later and stood up.
I had a briefing to run.
Dawn in the Tower wasn't light from outside. It was a slow brightening of the ceiling stones — the Tower's approximation of morning, arriving on its own schedule.
By the time it hit full brightness the safe zone was awake.
All sixty climbers. Every face carrying the Guardian countdown in their peripheral vision, doing what countdowns do to people.
Yuna had updated the diagram. The blank box wasn't blank anymore — annotated with the full attack sequence, timings approximated from my reported death durations, recovery window marked with an arrow and in neat letters: THIS IS WHEN YOU HIT IT.
I found Joren near the entrance.
Same as Day 1. Broad, composed, the Flame Emperor's particular energy of someone who had never seriously entertained the possibility of losing. He was talking to five other climbers — all mid-rank, all with the specific alertness of people who had decided to be useful rather than afraid.
He stopped when I approached.
"The Survivor," he said. Not mocking. Identifying.
"I know how it fights," I said.
That got me the full attention of all six of them immediately.
I talked. Yuna held up the diagram. I walked through the full sequence — sweep, overhead, interrupt, recovery window, the half-second tell before the interrupt, the geometry of the jump. I explained what happened if you ducked and why the jump needed a sideways component to clear the follow-up's radius.
Joren listened with his arms crossed.
When I finished he looked at the diagram. At the annotated patterns. At the marked recovery window.
His arms uncrossed.
"You learned all of this," he said, "by dying to it."
"Eleven times total," Yuna said, without looking up. "Four specifically on the Guardian."
He was quiet for a moment. "The tell before the interrupt. You're certain?"
"Weight shifts left half a second before the right arm comes across. If you see the shift you have time."
He nodded once. Turned to the five behind him and started distributing the information in his own words, my details intact. He was good at this. He'd been leading before today. Today he was leading with better information than he'd ever had, and watching him work I felt something that wasn't quite pride but lived in the same neighborhood.
"You're smiling," Yuna said quietly.
"I'm aware."
"You look slightly unhinged."
"That tracks," I said.
The Guardian was larger in full engagement than in a solo approach.
Not that it had grown. Context — sixty climbers at scale giving the height and reach something to measure against, the way a building looks taller when people are standing in front of it.
It waited in the center of the wide corridor with the patience of something that had done this seven times and seen no reason to adjust its approach.
The formation moved in.
The sweep came on the fourth second.
"*JUMP—*"
Some heard it in time.
Three climbers went down in the first pass.
Not down like I go down. The permanent kind. The kind the Tower doesn't send a notification for because there's nothing left to notify.
I felt the full weight of it — not grief, grief needs time, but the immediate complete awareness of finality. Three people breathing ten seconds ago.
I filed it.
The recovery window was open.
Joren hit it clean.
First real damage the Guardian had taken in seven attempts, judging by the way it moved afterward. Something reactive entering its motion — adjusting, recalculating.
Then it changed its pattern.
Not a reset. A modification — sweep shortened, follow-up coming earlier, interrupt switching arms. A counter. Not random.
Adaptive.
I hadn't told them about this because I hadn't known. Four deaths of data, none involving survival long enough to trigger the adaptation.
I did the only thing that resolved it fast.
I walked straight at it.
***
The new attack connected.
Twelve seconds. Cold stone. Back up, still in the corridor, fight still running six meters ahead.
"NEW PATTERN — SHORTENED SWEEP, EARLY FOLLOW-UP, INTERRUPT SWITCHES TO LEFT ARM—"
Joren's head turned. Adjustment made. The call moving back through the formation.
Yuna, somehow positioned at the formation's edge, was writing.
I didn't have time to appreciate this properly.
The Guardian's health bar had never shown this much damage across seven attempts. Climbers were hitting the recovery windows — coordinated now, Joren's voice and mine running call-and-response through the fight as the pattern evolved and I died for each new variation and came back with the update.
Death #13. Death #14.
Twelve seconds each time. Cold stone. Back up shouting.
Two more went down in the adaptive phase — the arm switch catching people who had learned the old pattern too well. I felt each one the same way I'd felt the first three. Filed them. Kept calling.
Then the tell came.
Weight shift, left side. The interrupt winding up.
"WEIGHT SHIFT — RECOVERY OPENING IN THREE—"
Joren was already moving.
The Flame Emperor hit the window with everything an S-rank class had been building since Day 1. The fire was a different quality than anything I'd seen from him — deeper, sustained, the kind of output saved for things that actually mattered.
The Guardian's health bar hit zero.
It fell.
The silence after something like that has a specific texture.
Not peaceful. Not triumphant. The silence of sixty people processing simultaneously — what happened, what it cost, what they're still holding onto.
Then the announcement came.
> [FLOOR 1 GUARDIAN — DEFEATED]
>
> First Clear Bonus — All Surviving Climbers:
> +1 Rank to all base stats

Seven.
I stood in the corridor and looked at the number.
34% historical survival rate. 12% today. Fifty-three people walking to Floor 2 who wouldn't have without the data. Every available metric called it a victory.
The math was correct.
I found I didn't much care about the math.
Across the corridor the family cluster was intact. My eyes found them before I'd consciously directed them there. The girl with the wide eyes spotted me from twenty meters and waved with the uncomplicated joy of someone who didn't yet understand what the number seven costs.
I raised a hand back.
Yuna appeared at my shoulder.
"Seven," I said.
"I know," she said.
"We saved fifty-three."
"I know that too."
We stood with it for a moment. Neither of us said which number was heavier. We both knew. And knowing was enough — to just stand there and let it be both things at once, the victory and the weight of it, without trying to resolve them into something cleaner than they actually were.
Joren stopped in front of me on his way past.
He looked at me for a moment. Then he nodded — once, the same motion as during the briefing but different in a way that didn't need words.
He kept walking.
I watched him go.
He makes others capable.
I didn't know why the thought arrived in exactly those words. It stayed anyway.
I was moving toward the Floor 2 corridor when the notification came.
Not gold. Not white.
Red.
I stopped walking.
> [ALERT — TOWER ADMINISTRATIVE NOTICE]
>
> Climber #4471
>
> Your revival ability has been flagged for formal review.
>
> An inquiry has been opened by:

Not a god. Not an entity with a redacted ID signing off as A Friend.
The Tower itself.
The Tower had administrative offices. An Architect. A formal review process. And it had looked at what I was doing and decided the correct response was an inquiry into whether I was allowed to keep doing it.
The gods watching me was one thing. Gods watched because something was entertaining — because I was an anomaly, a number that didn't fit the spreadsheet. Novelties got watched. That was manageable.
The Tower didn't do entertainment.
The Tower did rules.
And I was apparently breaking one.
I thought about Guardian's Echo. Ready in the Tower's system before I'd died to the Guardian four times. A skill that implied the Tower had been tracking me closely enough to anticipate it.
Like it had known before the gods had.
What does a Tower do with a climber who breaks its rules?
Fifty-three people flowed past me toward Floor 2. I stood in the corridor and thought about the seven who weren't among them, and the hundred floors above me, and the word review, and what it meant that the Tower had a word for what I was doing.
The word wasn't impossible.
It was irregular.
Irregular could be reviewed.
Irregular could be corrected.
Yuna stopped beside me. She read my expression. She didn't ask — she just waited, which was the thing about Yuna that I kept not finding the right words for.
I looked up at the ceiling. Featureless stone, same as always. Somewhere beyond it, something with an Architect's Office and a metric for what counted as a rule.
Then I looked at the corridor ahead. Open. Floor 2 entrance lit in the same dim Tower-glow as everything else.
Fifty-three people moving through it.
One more to go.
I started walking.
