The corridor ended in a door.
Just iron. Old, heavy, the surface pitted with rust and something darker that had dried in streaks down the lower half. No handle on it. Just a flat panel set into the stone beside it, same pale glow as the registration screen, and when I got close enough it lit up by itself like it had been waiting.
FLOOR 1 — TUTORIAL STAGE INITIATED
CURRENT LEVEL: 1
HP: 340/400
I stared at that for a second.
340 out of 400. So I had a health pool now, apparently, a number assigned to how alive I was, and the knife had taken sixty points of it. That's what three years of being the support meant in this place — my base HP was higher than a pure fighter would've had at level one, all those hours absorbing hits so the real fighters didn't have to, converted into a number by whatever system ran this Tower.
Sixty points gone from a knife Den held.
I pushed the door open before I could think about that too long.
The smell hit me first. Wet earth and something underneath it, something that had been rotting for long enough that the rot had become just part of the air, background noise for the nose. The corridor opened up into a cavern — wide, genuinely wide, the kind of space that reminded you how small you were — with walls slick from moisture and a ceiling lost somewhere in the dark above. Bioluminescent moss grew in patches across the stone, pale green, throwing just enough light to see shapes by without ever quite letting you see them properly. Stalactites hung overhead. The floor was uneven, pitted with puddles that reflected the moss-light in shaking smears.
And the sounds.
Skittering. Low and fast and coming from more than one direction at once, overlapping, the kind of sound that made the back of your neck do something involuntary.
I stood in the entrance and listened and tried to assess. No weapon. No boots — the stone was cold and slightly wet under my feet. No pack, nothing. Just me and the quill-shaped stalactite shard I'd picked up in the corridor, about the length of my forearm, one end naturally sharp.
I'd gone into dungeons with an S-ranked party and full equipment and still come close to dying twice.
I had a rock.
Okay.
A shape moved in the dark to my left and my body moved before my brain did — I stepped right, fast, and the thing landed where I'd been standing with a sound like a wet slap. It skittered, reorienting, and in the fraction of a second it took to find me again I got my first proper look at it.
About the size of a large dog. Eight legs, each one ending in a hooked claw that clicked against the stone. Pale, almost translucent — I could see the dim outline of something moving inside its body, some dark fluid shifting as it moved. No eyes. Just a face that was mostly mouth, hinged wrong, opening sideways instead of up and down, and when it found me by smell or vibration or whatever it used the mouth opened wide and it made this sound — short, sharp, wet, like a scream produced by something that had never learned what screaming was for — and launched itself again.
I swung.
The shard connected with the side of its body and the impact went all the way up my arm and into my shoulder and it was nothing like hitting something should feel, more like hitting a sack packed tight with wet sand, this horrible giving resistance that absorbed the blow without the thing actually going down. It tumbled sideways, hit the ground, righted itself with those eight legs in about a second.
Faster than I expected.
It launched again and I swung again and this time I caught it mid-air, which was luck more than skill, and the impact was better — something crunched in whatever passed for its midsection and dark fluid started leaking from the crack. It hit the ground and this time getting up was slower, two of the legs on its right side dragging.
I went to it.
Swung twice more.
After the second hit it went still.
I stood there breathing hard, looking at it, feeling the adrenaline in my hands and the soreness already building in my shoulder from the impacts. My heart was going way too fast and my feet were cold and there was a moment, brief, where I just — registered it. This is real. I'm in a monster dungeon with no equipment and I just killed something with a rock and that was the easy one.
The notification appeared in my peripheral:
CAVE SCUTTLER (COMMON) DEFEATED.
EXP GAINED: +45
LEVEL 1 (245/500 EXP TO NEXT LEVEL)
And then underneath it, after a second:
MONSTER CORE AVAILABLE — CONSUME FOR STAT BONUS?
I looked at the dead Scuttler.
Thought about it.
My stomach made a sound that answered for me — this long low groan that I'd been trying to ignore for the last however long it had been since I'd eaten, which was before the dungeon run, which was at least fifteen hours ago, possibly more. I'd been unconscious on that altar for some amount of time I didn't know and I'd been walking this corridor and now I was here and my body had run its fuel down to nothing and it was letting me know.
I crouched beside the Scuttler.
Found the core by feel more than sight — a small dense mass near the center of the body, darker than the surrounding tissue, about the size of a walnut. The texture when I pulled it free was — I'm not going to describe the texture. I just ate it. Chewed twice, swallowed, moved on.
It tasted like nothing. Almost aggressively like nothing, which was in its own way worse than if it had tasted bad.
MONSTER CORE CONSUMED.
+0.5 VIT
Half a stat point.
I stood up and looked at the cavern stretching out ahead of me, the green moss-light and the shadows and the sounds still coming from every direction, and I thought — half a point. Half. I killed that thing and ate part of it and got half a stat point and if that's the rate then I was going to need to eat a truly unreasonable number of monsters to matter.
But half was more than zero.
I found the next one by following the skittering.
There were eleven Scuttlers in the first section of the cavern.
I know the exact number because I counted, partly to stay focused and partly because somewhere around the fifth one I realized I was building something — not skill exactly, not yet, more like the raw material that skill gets made from. With the first one I'd just swung and hoped. By the third I'd noticed that they always cocked their body slightly to the left before launching, a tell so consistent it had to be hardwired, and I started using that. By the fifth I was moving before they jumped. By the eighth I wasn't scared of them anymore.
That worried me a little.
Getting comfortable got people killed. Lira had said that once, during a mission briefing, not to me specifically, to the group, but I'd been the one listening properly. The moment you stop being scared of something is the moment it catches you.
I stayed alert.
The last three Scuttlers came at me together — not coordinated, not intelligent, just three creatures in the same territory all alarmed at the same time — and that was harder, tracking all three, getting hit once across the ankle by a claw that tore skin and stung badly and left a thin line of blood across the top of my foot.
I killed all three.
Stood in the middle of them and assessed damage: ankle bleeding, not deep. Left palm raw from gripping the shard so hard for so long. Everything else okay.
I ate every core I could find.
First one: +0.5 VIT. Second: +0.5 VIT. Third: +0.3. Then +0.2. Then two at +0.1 each. The last three gave me a notification that just said INSUFFICIENT NUTRITIONAL VALUE, which I was choosing to interpret as the system's way of telling me I'd gotten everything these things had to offer.
My HP had climbed to 380. My stomach had stopped screaming, a little.
I found the door to the next section in the far wall.
I went through.
The second section was darker. The moss thinner, the patches further apart, the puddles bigger. And the sounds were different — no more skittering. Something heavier. Slower. Deliberate.
I stopped just inside the door and let my eyes adjust and waited.
Thirty seconds passed.
A minute.
There — movement. To the right. Low to the ground, but the wrong kind of low, not crouching-to-spring low, just — large, and close to the ground because that was its natural height. The shape resolved gradually as it moved toward a patch of moss-light: six legs, a body like a boulder with biology attached to it, a carapace that looked like overlapping plates of dark stone. Each leg came down with weight and deliberation, feeling out the ground before committing. It moved the way very old, very heavy things move, without urgency, because urgency implies something might stop it.
The head — if that was the right word for the flat armored plate at the front — had its mouth on the underside, circular, and when it opened to smell the air I could see the crushing teeth in rings, designed for grinding rather than cutting.
GREYBACK CRAWLER (UNCOMMON)
The system helpfully did not tell me how to fight it.
I looked at my shard.
I looked at the Crawler.
The Crawler found me with whatever sense it used and turned to face me fully. It didn't charge. It just — oriented. And then started walking toward me at exactly the pace required to close distance, not fast, just steady and completely committed, like it had decided this was happening and saw no reason to rush the outcome.
I threw the shard at it.
The shard bounced off the carapace and skittered away.
The Crawler didn't even slow.
I ran.
I ran to the wall, hands going up, finding holds in the rough stone, climbing. Got three feet up before I heard the Crawler's pace change — not faster, just more purposeful — and then one of its legs swept sideways like a scythe and caught me across the back and I came off the wall and hit the ground and the impact drove the air completely out of my lungs.
For three seconds I just lay there because there was nothing else to do, no air to breathe, body in full panic, the world reduced to the single urgent need to inhale.
The leg came down.
I rolled. The foot hit stone where my head had been and I felt the impact through the ground. Rolled again, got to my knees, forced myself upright even though my back was screaming and my lungs were still only half-functional.
The Crawler turned. Patient. Tracking.
Okay. Not the wall. Not direct hits on the carapace. Think.
The legs.
I'd fought enough high-defense dungeon monsters as support to know the principle — armor covers the main body but it has to bend somewhere, has to have joints, and joints mean gaps. I retrieved my shard from where it had fallen, got a better grip on it this time with both hands, and watched the Crawler come toward me and waited.
When it was close enough I stepped inside the sweep of the next leg and drove the shard into the joint where it connected to the body.
It went in maybe an inch before stopping, not deep, but the Crawler lurched and made a sound — low, grating, more vibration than noise — and the leg retracted. I pulled the shard free and moved before the next leg could come around. Kept moving, kept circling, looking for the same joint on a different leg.
The second attempt I nearly got the timing wrong. The leg came down on my shoulder instead of my head only because I stumbled — genuinely stumbled, foot in a puddle — and the angle changed at the last second. The impact was still enough to send me sideways and I hit the ground knee-first on stone and something in the knee flared white.
I didn't stop.
Got up. Circled. Found the joint. Drove the shard in again.
The third time I got it right — the Crawler was slightly slower now, compensating for the two damaged joints, its movement patterns adjusting in a way that made the next joint easier to reach. I got the shard in deeper this time. Twisted it. The Crawler lurched badly, its whole right side dipping, and that was the opening.
I went for the underside.
The mouth-side.
Not to attack the mouth — just to get underneath the armor plating, where the body met the ground. Less protection there. Had to be. I got under it, flat on my back in a puddle which was — not ideal — and drove the shard upward into the softer underbelly repeatedly, fast, not elegant, just putting as much force as I could into a confined space.
The Crawler tried to roll onto me. I had just enough warning from the way the legs repositioned to scramble clear.
It took me twenty-three minutes to kill the Greyback Crawler.
I know because I counted, roughly, estimating from my breathing rhythm. Twenty-three minutes for one Uncommon mob with a rock and sore hands and a knee that was complaining loudly about its earlier meeting with the stone floor.
When it finally went still I stood over it and I couldn't tell if I was going to laugh or be sick.
GREYBACK CRAWLER (UNCOMMON) DEFEATED.
EXP GAINED: +120
LEVEL UP — LEVEL 2
STAT POINTS: +2 (AUTO-ASSIGNED — SURVIVAL PROTOCOL: +1 STR, +1 VIT)
The level-up felt like nothing. No dramatic rush of power, no sudden warmth. Just a slight clarity, a very subtle settling, like something had been slightly loose and was now slightly less loose. If I hadn't been told by the notification I might not have noticed at all.
I ate the core. This one was larger than the Scuttlers', denser, and it actually tasted like something — faint iron, something faintly sweet underneath it that I couldn't identify.
+1 VIT
That one I felt. A thread of warmth spreading outward from my chest, the edge of the knee pain pulling back half a degree, my vision sharpening slightly. Not fixed. Just — better, a fraction, enough to matter.
I looked around the section.
Two more Crawlers in the dark. At least.
I picked up my shard, checked the point — dulled somewhat but still usable — and went to find them.
The second Crawler I handled better. Figured out earlier which joints to target, spent less time getting hit, finished in fourteen minutes. Still ugly. Still painful. But fourteen minutes rather than twenty-three.
The third one nearly killed me.
It came from behind — I hadn't realized there was a third, thought I'd located all of them, made the assumption that nearly ended everything right there in Section 2. It hit me from the left side before I heard it coming, a leg-strike that caught me across the ribs and lifted me off the ground and threw me six feet into the wall. I hit shoulder-first, the bad shoulder, the one that had been complaining since the first Crawler, and something in the joint made a grinding sensation that wasn't quite a sound and was definitely not good.
I slid down the wall.
HP: 97/460
Ninety-seven.
I'd been at 380 coming into this section and I was at ninety-seven now, one hit from a thing I hadn't seen coming, and it was already turning toward me with that awful patient deliberateness.
My shoulder wasn't right. I could move it but something was grinding in the joint and lifting my arm above chest height sent a spike of pain up into my neck that made my eyes water.
I switched the shard to my left hand.
And fought the third Crawler left-handed, half-blind from the shoulder pain, with ninety-seven health points and nothing else.
It took thirty-one minutes. The worst thirty-one minutes of my life up to that particular moment, which was a bar that was going to keep getting reset, I was starting to understand. I got hit four more times, each one taking chunks of health I couldn't afford, and by the time it went down I was at forty-two HP and sitting in a puddle because my legs had just quietly decided they were done standing up for now.
Forty-two.
I sat there and ate the core — +1 VIT, some health restored — and watched my HP climb to a deeply unimpressive sixty-three and thought about the fact that I had no idea how many more sections this floor had.
None of the stories people told about the Tower ever mentioned a map.
I got up before my brain could do anything useful with that thought and found the door to Section 3.
