Thirstfall - Memory of a Returnee-Chapter 84: Momentum

The lesser beasts know.

The second the Reef Stalker decloaks, the surrounding Shellcats and Gargolites scatter like roaches when the kitchen light flips on.

They don’t retreat out of cowardice—they retreat out of biological programming.

An apex predator doesn’t share its kill zone. Everything Rank F, E, and D within a fifty-foot radius vanishes into the chaos of the broader battle, leaving an eerie pocket of empty sand between us and the monster.

A private arena. How generous.

The Stalker doesn’t waste time. It pivots toward Boris, who’s still on the ground, struggling to push himself upright with one arm. Easy prey. Wounded. Slow.

I step into its path.

The beast’s claw comes in fast—a lateral swipe aimed squarely at my throat with the casual precision of something that has killed ten thousand times and stopped counting.

I bring Eventide up to deflect, but my timing is wrong. A fraction of a second too late. The parry catches the claw at a bad angle—torqued, sloppy, the kind of block that saves your neck but costs everything else.

The deflection holds. My throat stays intact.

The kinetic transfer doesn’t care about my throat. The sheer force behind the swipe launches me sideways through the air.

I feel my ribs flex past their design limit before I hit the sand, rolling twice, tasting blood and grit.

Even at Rank E, the gap between Shallow and Reef is a canyon.

I try to stand. My legs are answering, but they’re answering slowly—the kind of delayed response that means something inside is bruised badly enough to protest every command.

The Stalker shifts its milky, soulless shark eyes from Boris to me.

I’m bleeding. I’m slower. I’m the weaker target now. Fine...

It charges.

Get up, Dryden. Get up or die in this sand.

The killing machine launches itself at me, all two thousand pounds of chromatophore-scaled muscle landing squarely on my chest. The impact drives me into the ground so hard the sand craters around my body.

I ignite Eventide on pure reflex, jamming the shadow-blade between my face and its claws. The beast rakes down—once, twice, three times—each strike passing a hair’s width from my ears, the displaced air hot against my skin.

Its weight is crushing my lungs flat. The edges of my vision are going dark.

I hear the HUD screaming. I don’t need to check. I’ve heard that specific alarm for a decade. Critical OXI drain. The Stalker is eating my OXI alive.

Its bifurcated jaw unhinges, descending toward my face. Rows of serrated teeth fill my entire field of vision. The stench of brine and rotten meat floods my nostrils.

Not today.

I chamber my knee and activate [Pressure Step.]

The Ironwake Reefs scream. A violent jet of hyperpressurized steam erupts from my heel as I drive my boot upward into the softest tissue the beast has to offer—genitals.

Dead center. No mercy. Sympathy is for people with better options.

The sound the Stalker makes isn’t a roar. It’s a wheeze—a high-pitched, airless hiss, like every cubic inch of oxygen just left its body through a single point of agony.

It leaps backward off me instantly, its massive frame contorting in reflexive, primal pain.

I suck air into my flattened lungs and roll sideways, putting distance between us.

Heavy boots crunch in the sand beside me. Boris drops into position at my shoulder, still upright but barely. His left arm hangs at a grotesque angle, and the beast-hide armor on that side is shredded down to the skin—the impact dislocated his shoulder clean out of the socket.

"Need a hand?" I ask, forcing myself upright.

"Put it back for me, kid."

I glance at the Stalker. It’s recovering, shaking its massive head, chromatophores flickering between camouflage and fury.

I calculate the window.

Enough.

I grab Boris’s forearm with both hands, brace my foot against his ribcage, and pull.

CLACK.

The joint snaps back into its anatomical seat. Boris grunts—a single, controlled sound that tells me this isn’t the first time someone’s reset his bones in the middle of a fight.

But as his damaged armor shifts with the manipulation, my eyes catch something that makes my tactical brain stutter.

Boris’s class tattoo.

Every Diver’s class insignia is branded onto the left shoulder by Ocean’s Law upon awakening. It’s permanent. Immutable. Part of the system’s identification architecture.

Boris’s left shoulder—the one I just fixed—is bare.

Not bare as in hidden beneath armor. Bare as in the tattoo is gone.

Completely erased.

Only a faint, raised border remains on the skin, like the outline of something that was surgically removed—or forcibly overwritten.

I look at Boris, searching his face for an answer.

He catches my gaze instantly. Reads it. And does the one thing that tells me everything I need to know about the depth of that secret.

He pulls his torn cape over the shoulder, covering the blank skin completely.

"We have something more urgent right now, kid," he says, pointing his axe at the Stalker.

The beast is already coiled, muscles loaded, chromatophores shifting into full combat display.

He’s right. But I’m filing this under the same mental folder as the Echo Fragments and the Leviathan’s missing exit fee.

Things that shouldn’t be possible in a system that’s supposed to be absolute.

"Formation?" I ask.

"Momentum," Boris replies. A grin cracks through the pain on his face.

"Good call."

Momentum forcing. Simultaneous attacks from a coordinated pair, striking from opposite vectors to eliminate the target’s ability to defend both angles. The geometry is simple. The execution is not.

I haven’t run this formation since the trenches of the Deep, years before I hit Rank A. The nostalgia tastes like blood and adrenaline and something uncomfortably close to joy.

I break left. Boris breaks right.

The Stalker tracks me—the faster target, the one who just kicked it in the worst possible place. Its milky eyes lock onto my trajectory, muscles coiling for an intercept.

That’s the point.

I swing Eventide in an ascending arc, targeting the beast’s front legs. The shadow-blade screams through the air. The Stalker reads the attack and dodges—fluid, impossibly fast, exactly the way I remember these things moving.

But momentum formation is merciless. The dodge takes it directly into Boris’s line.

Boris is already committed.

His war axe descends in a brutal, overhead cleave powered by every pound of Rank-C muscle in his massive frame.

The blade catches the Stalker’s neck with the full weight of a man who has been killing things bigger than himself for longer than most people stay alive in Thirstfall.

The axe bites deep. The beast’s scream is guttural, primal—a sound that vibrates in the chest cavity and turns the blood acid. It thrashes violently, ripping free of the embedded blade, and leaps backward, trailing a thick arc of glowing blue blood across the sand.

Its chromatophores go haywire. Colors ripple across its skin in violent, unstable patterns—not camouflage.

Rage. Pure, biological fury pushed past the breaking point.

Then the Stalker tilts its massive, bifurcated jaw toward the starlit sky and releases a sound I have never heard a Reef Stalker make.

It isn’t a roar. It isn’t a hunting trill.

It’s a call.

A pulse of deep, crimson light erupts from the horizon behind us, shooting straight upward into the darkness. It hits the atmosphere and detonates silently, spreading outward in a shockwave of red light that washes across the entire sky from horizon to horizon.

The battlefield goes still.

Every monster on the field freezes for exactly one second. Then, as one, they resume fighting with doubled ferocity.

Boris lowers his axe. His grin is gone. The jovial bear, the laughing commander—all of it stripped away, replaced by something cold and ancient.

"Finally," he says, his voice barely above a whisper.

[Warning OXI Low]

[OXI: 87/1,600]

I look at him. "What was that?" I ask, worrying about my empty tank.

Boris doesn’t answer immediately. He watches the red light fade from the sky, his jaw set with the heavy resignation of a man who has seen this before and hoped he wouldn’t see it again.

"End of Phase One."
