The world inverted. One moment, Z-69 stood on solid ground inside the Faceless Trading Shop, the next, gravity released him and the pink Miracle Door swallowed him whole. He fell. There was no wind, no sound, and no sense of distance—only a cold older than recycled air, one that seemed to have forgotten warmth before humanity learned how to create it. The violet crystal in his chest flared. Its light reached perhaps three inches before surrendering. This was not black. Black was still a color. This was its absence.
Lumina tried to scream, but sound did not function here. Instead, her terror struck through their bond as raw animal panic, and her claws pierced his collar before sinking into the corpse-pale skin beneath it. Don't let go. Don't let go. Don't let go— Z-69 could not answer. He could only feel her fear beside his own unnatural calm, the calm of someone who had already died and found the condition less permanent than advertised. Then the fall ended. The void spat them out.
A surface materialized beneath Z-69's feet with the lazy indifference of a host who had stopped caring about first impressions centuries ago. He landed hard, one hand striking ground that felt like wood and looked like solidified shadow. The impact rattled through his bones, and the crystal inside his chest answered with a slow pulse that spread through his ribs like distant thunder. Thrum. Thrum. Steady. Unhurried. A rhythm that had survived three hundred years of apocalypse without needing a living heart.
Lumina clung to his shoulder. Her claws remained buried in his shirt. Z-69… where are we? He did not answer immediately. His eyes adjusted to the space—or tried to. Darkness moved in layers, suggesting depth where no architecture should have existed, with no visible ceiling, no walls, and no boundary separating the floor beneath him from the void around it. Only endlessness.
Shelves rose from that darkness like the spines of sleeping giants, row upon row stretching beyond the violet glow beneath glass cases, sealed crates, wooden chests, weapon racks, metal sarcophagi, and boxes marked in languages his eyes rejected before his mind could translate them. Tell me you see this.
"I see it." See what?
"Everything." The answer was useless because he understood nothing, not the architecture that was not architecture, not the shelves that appeared infinite, and not the way ancient relics rested beside future weapons as if chronology had been dismissed as a minor administrative inconvenience. Nothing belonged together. Ancient beside modern. Magic beside machinery. Civilizations forced into one collection by someone who either did not respect time or had survived long enough to become bored with it.
Lumina stared into the dark. It looks like someone exploded a museum.
"More than that." Z-69 rose carefully.
"It looks like someone exploded several museums, then reconstructed them during a fever dream." A tiny sound escaped her. Under better circumstances, it might have been laughter. He studied the nearest shelves. A cracked wooden chest bound in black iron breathed with a rhythm too deep to be human, while beside it a rifle longer than anything used on Level Ten rested on a display rack with its barrel glowing faint blue. The scope pulsed once. Then turned toward him.
No visible mechanism should have allowed the movement, yet the weapon looked past his skin, past the violet crystal, and into something deeper. The rifle blinked. Z-69 looked away first. Those things are watching me. Lumina pressed herself tight against his neck. Her heartbeat was rapid, tiny, and unmistakably alive. Z-69 let his gaze pass across the shelves. He could feel awareness without bodies pressing against his skin.
Some were hungry, some curious, and a few possessed the patience of things that had waited longer than recorded history.
"Not exactly watching," he said. Then what are they doing?
"Evaluating." Evaluating what? The crystal pulsed.
"Compatibility." The word settled between them like a stone dropped into still water. Then a voice arrived.
"Welcome back to my humble little establishment." It carried no echo or direction. No footsteps announced its owner. The Faceless Merchant simply stood three meters away. He had not approached, reality had merely decided to include him. Black suit. Black gloves. White mask. Painted smile. Hands resting casually in his pockets.
"Ah," the merchant said, tilting his blank face.
"I see you have found the Outerworld Armory." He spread both arms toward the endless shelves.
"This is where I keep my rare and one-of-a-kind weapons. My personal collection. My magnum opus. I thought you might appreciate the atmosphere." Z-69 looked around. Shelves stretched into darkness, weapons breathed, relics watched, and crates whispered in languages without mouths.
"It looks like the armory of someone with a severe hoarding disorder." The Faceless Merchant laughed, a real laugh this time, warm enough to sound human and polished enough to make the humanity suspicious.
"Hoarding disorder. That is new. Most visitors use words such as terrifying, eldritch, or why, God, why?"
"I am not most visitors."
"No." The painted smile faced him.
"You truly are not." The merchant stepped forward without making a sound, as though the shadow-floor had agreed not to acknowledge his weight.
"This is not hoarding. It is curation. Preservation. The art of keeping what matters after the world forgets why it should." He stopped beside a shelf rising several stories into the dark. A weapon rested across it that made even Z-69 pause. A great sword stretched three meters across the shelf, its blade nearly as thick as Z-69's thigh and covered in burn marks and gouges left by battles against creatures capable of generating their own fire.
"This one has history," the merchant said, patting it with obvious affection.
"Its previous owner crossed three demon kingdoms to claim it. Lost an arm and an eye, but his swings were poetry." Z-69 gripped the hilt, yet the sword did not move, not a tremor, not a shiver, not the smallest acknowledgment that someone had tried. He tightened every available muscle and let the crystal supply more energy to his limbs. The weapon ignored him with the absolute certainty of a mountain.
After several seconds of feeding strength into an object that regarded him with geological indifference, he released it.
"I am not that monster."
"No," the merchant agreed.
"That is not an insult. His swings were poetry, but poetry often demands a willingness to lose things." His mask tilted toward Z-69.
"You have already lost enough for several lifetimes." Z-69 looked at him.
"What does that mean?"
"Everything and nothing. Come. I have other options—something better suited to your current configuration." The merchant hopped. One moment he stood beside the great sword. The next, he waited before a glass display containing a spear with a black iron shaft and a tip filled with captured starlight.
"This one suits your appetite," he said.
"Once driven into a target, it drains nearby biological energy and pumps it into the wielder's heart—or core, should the customer no longer possess the first." He paused.
"You are always hungry, after all." Z-69 stared at the spear. The Hunger inside him responded before thought could interfere. The weapon resonated with that endless demand strongly enough to make the crystal tighten inside his chest.
"How much?"
"Normal price: one soul." The merchant raised one finger. The tale has been illicitly lifted; should you spot it on Amazon, report the violation.
"Discount price: half a soul." Z-69 considered it.
"A bit expensive."
"Indeed. However, it does not necessarily need to be your soul, provided the substitute is valuable." Lumina's claws tightened. Absolutely not. Z-69 nodded.
"Next." The merchant seemed amused. Another hop brought them to a black whip coiled inside a glass cage, barely wider than Z-69's smallest finger and made from wet organic tissue that shifted despite remaining still. It breathed. Actually breathed. Z-69 reached toward the cage. The whip lunged through the glass as if the barrier were smoke, wrapped around his wrist, and tightened. Thousands of microscopic receptors pressed against his skin, tasting him. Cold. Slimy. Curious. He pulled back.
The weapon resisted for half a second before releasing him.
"No." The merchant tilted his mask.
"It is slimy," Z-69 explained. Lumina recoiled so far she nearly fell from his shoulder, her disgust striking through the bond before the words arrived. That thing was licking you. The merchant looked between them.
"Most customers scream or run. You two judge my inventory as though reviewing dishes on a menu." Z-69 flexed his wrist.
"The menu is part of the experience."
"Touché." Another hop. A silver gun appeared on a velvet-lined stand, shifting engravings flowing across a frame elegant enough to be beautiful and strange enough to be immediately untrustworthy.
"This weapon fires exceptionally well," the merchant said as he picked it up.
"Each bullet can detonate twenty separate times. Not twenty bullets—one bullet, twenty explosions. Excellent for chain-reaction devastation." He turned it in his hands.
"But—" A seam opened along the barrel. Then a mouth emerged. The vertical slit filled with metal teeth before opening wide.
"FUCKING HELL! DO NOT PAT ME LIKE A DAMN DOG, YOU MASKED IDIOT!" The voice was metallic, furious, and carried the exhaustion of a sentient object that had endured too many owners.
"I HAVE TOLD YOU A THOUSAND TIMES—HOLD THE HANDLE, NOT MY HANDS! IF YOU WANT TO ADMIRE ME, DO IT FROM A DISTANCE LIKE A CIVILIZED WEAPON APPRECIATOR!" Lumina launched from Z-69's shoulder like a blue comet and crashed into a nearby shelf. Do not buy that one. Do not. Z-69, if you buy that one, I will bite your ears off. Z-69 nodded slowly.
"Agreed." The gun's mouth twisted with enough mechanical contempt to suggest it had practiced the expression.
"Oh, very mature. A talking weapon. How novel—""Moving on," Z-69 said. The merchant chuckled and returned the gun to its stand. It continued cursing until the darkness swallowed its voice.
"You are remarkably selective," he observed.
"Most customers want power regardless of its form. You want appropriate power."
"We want survival," Z-69 replied.
"Power that fights its wielder is not power. It is a liability."
"Hm." The merchant studied him.
"Given your condition, I expected desperation to override preference."
"Desperation kills faster than enemies." Then Z-69 stopped. A vibration passed through him, light, gentle, almost imperceptible, yet strong enough to lock his body before conscious thought could identify it. He felt it inside the crystal and along bones where three centuries had carved pathways for a frequency he no longer remembered learning. The Thunderlight within him trembled. Not warning. Recognition.
His head turned toward the farthest corner of the armory, past weapons that watched, relics that whispered, the breathing chest, and the distant gun still muttering insults into a darkness that seemed content to listen. There. An ancient display case waited beneath cracked sealing talismans, its clouded glass concealing whatever lay inside while a single fracture split the center in the exact shape of a lightning bolt. Z-69? What are you looking at? He was already walking.
Each step carried him forward with the inevitability of water flowing downhill while the merchant fell silent and even the darkness seemed to lean closer, attentive to a reunion older than Z-69's conscious memory. The crystal pulsed harder. Thrum. Thrum. THRUM. The glass case opened—not because Z-69 touched it, but because whatever waited inside had already made its choice.
Inside lay a short blade, neither long enough to be a sword nor short enough to be a dagger, roughly the length of his forearm and built for precision rather than brute force. Black and purple coexisted across the blade without mixing. Lightning patterns lay frozen inside the metal—not engraved, but imprisoned. Waiting. Old leather wrapped the hilt, a deep burn scar marked one side as the work of fire, plasma, or something hotter than either, and along the spine ran an inscription worn almost beyond recognition.
The language was older than his understanding. Yet the remaining characters felt familiar. Not intellectually. Not through memory. Through his body. Through the same instinct that knew how to survive falling, starvation, and lightning. Z-69 reached for it. Wait— His fingers closed around the grip. The world shifted. Violet radiance erupted from the crystal and flooded the armory, forcing back the eternal darkness. For one brilliant and terrible moment, Z-69 saw the true scale of the collection. Infinite shelves.
Infinite weapons. Infinite things watching. The short blade screamed without sound—recognition, reunion, and the violent relief of something that had waited too long finally finding the hand it remembered. The blade trembled as violet light raced across its surface. Frozen lightning began moving within the metal, and thunder rolled through the armory—not heard, but felt. A pressure wave struck Lumina and sent her tumbling several rows away.
The Faceless Merchant folded his arms with the resignation of someone watching an old prediction fulfill itself.
"Everyone chooses the wrong weapon during the first three attempts," he said conversationally.
"The confident ones grab the great sword and break their spines. The clever ones negotiate for the spear and discover the price is worse than death. The brave ones reach for the whip and—""I know how to use it." Z-69's voice emerged rough, scraped across something dormant, and when the weapon pulsed, fractured images forced themselves through the sealed dark of his memory. A battlefield beneath a sky torn open by thunder. Rain falling as fire.
His hand holding this blade while violet light moved through it in clean, economical strokes. No wasted motion. No hesitation. No mercy for rot. The memory faded. The knowledge remained.
"I know how to use it," he repeated.
"Good." The merchant clasped his hands.
"Then we should discuss the price." Z-69 had known this was coming.
"How much?"
"Normally, your entire fortune, plus one arm and one leg." A pause.
"Literally." Z-69 stared at him.
"The weapon is priceless," the merchant continued.
"Its worth exceeds the wealth of small nations, and under normal circumstances acquiring it would require a sacrifice large enough to make you regret being born."
"Not reasonable."
"No. Hence the special offer." He pointed toward Z-69's forehead.
"I will take one memory shard." Z-69's fingers tightened around the hilt.
"Which memory?"
"I choose." The merchant's voice carried neither cruelty nor malice. That almost made it worse.
"Do not worry. I will not take anything important. Perhaps you will never notice. Perhaps you will merely feel mildly confused." Lumina scrambled back toward them, fur dusty and eyes blazing. Mildly confused? He just woke up. His memory is already a cracked bowl, and every piece matters because so few remain. You cannot simply—"My dear," the merchant said calmly, "commerce does not care about cracked bowls. Commerce cares about value." His mask turned toward Z-69.
"One memory shard from a collection as depleted as his is a small price."
"It does not matter," Z-69 said. Everyone went still. He stared at the weapon and at the lightning patterns moving with the rhythm of his crystal.
"I have almost nothing left to lose. Most of my memories are already gone." Lumina looked at him as though the sentence had struck her harder than any weapon in the armory could have managed.
"What is one more piece of absence?" Z-69—"It is fine." It is not fine.
"It is what it is." The painted smile seemed to brighten.
"Transaction accepted." A gloved hand touched Z-69's forehead. The contact was gentle, warm, and wrongly intimate as the merchant's fingers pressed, then reached into the hollow place where memories should have lived. Something pulled inside Z-69's skull. A tug at first. Then a hook. The crystal in his chest skipped one pulse. Thrum. Silence. Thrum. Then something vanished.
Purple light drifted from Z-69's forehead and condensed into a bead-sized orb, beautiful and fragile in the way stolen things often became once separated from the person who had owned them. A memory made visible. The armory tilted. His knees buckled, but Lumina caught him with blue light before he hit the floor. Did you forget something? Her voice was high and panicked. Z-69 blinked until the room stabilized. The Faceless Merchant stood before him, holding the orb between two fingers.
"Something small," Z-69 said. What was it? He searched the hollow in his mind. Nothing answered.
"Does not matter." It matters if you cannot remember what is missing.
"It may return." He looked at the blade. Its violet patterns had calmed, and its hum now matched the crystal inside his chest. The weapon no longer felt like a stranger. It felt like part of him.
"Or it will not. Either way, I have this." The merchant placed the memory inside a tiny glass jar, sealed it with the practiced efficiency of someone who had bottled pieces of people before, and slipped it into one of his endless pockets.
"Done. Transaction complete." He bowed.
"Take good care of that blade. It waited a very long time for you." Z-69 studied the weapon, then surprised himself by saying, "Thank you." The merchant seemed pleased.
"Oh. I nearly forgot." He produced a white card from empty air. It floated toward Z-69, who caught it between two fingers. Smooth cardstock. Expensive weight. A black smiling-mask logo.
"My business card. Crush it when you require my services, and I will come." The merchant paused.
"Send my regards to John. I miss him dearly." Then he stepped forward and kicked Z-69. No spell. No ceremony. Only a simple, disrespectful boot to the body. The Outerworld Armory vanished. The merchant disappeared, the endless shelves dissolved into darkness, and even the darkness gave way to neon. Z-69 hit wet concrete. Garbage shifted beneath him, releasing the familiar perfume of Level Ten: chemicals, rot, recycled air, and civilization pretending none of those things counted as atmosphere.
Lumina landed beside him in a blue heap. Neither moved for several seconds. Then her dazed voice reached him. Did we survive?
"Yes." Z-69 sat up and touched the empty ache in his head.
"Although it feels like being pickpocketed." Because you were pickpocketed.
"I prefer the term commerce." I prefer robbery with additional steps. He set her upright and looked at his hand. The short blade remained with him through the void, the kick, and the landing as though separation were no longer acceptable, its weight already familiar and its resonance synchronized with the crystal's pulse. Z-69 retrieved the business card from the garbage.
"Faceless Trading Shop," he read. The blade hummed.
"Good," he said quietly.
"I needed this." He stood. The alley stretched beneath buzzing signs and artificial rain as the usual sounds of Level Ten returned around them—arguments, machinery, gunfire, laughter, and the stubborn noise of a district refusing to admit it was dying. John waited at the far end. He leaned against the wall with his arms crossed, looking as though several hours of anxiety had fermented into something strong enough to strip paint.
"I disappear for three hours," he said as Z-69 approached.
"Three hours. I leave you alone for one supply run, come back, and find no note, no message, and no trail except several witnesses claiming a silver-haired lunatic scammed a casino before walking through a wall." He stopped. His eyes found the blade.
"What is that?" Z-69 raised it. Black-purple metal caught the neon and answered with thin violet lines.
"I do not remember every detail, but I believe I purchased it." Lumina climbed onto his shoulder, furious and exhausted. He traded a memory to the Faceless Merchant for it. The telepathic shout struck John like a physical blow. Confusion crossed John's face, then disbelief, then horror, and finally a pale fury so precise it looked rehearsed by three centuries of dealing with the same masked criminal.
"FACELESS MERCHANT?" Both metal hands dragged through his hair.
"What the hell? You sold a memory to that masked scam artist?" Z-69 studied him.
"You know him."
"Unfortunately!" John pointed at the weapon.
"The next time I see him, I will turn that mask into scrap."
"At least I have a blade now."
"A blade—" John's fingers clenched until metal creaked. Smoke escaped from somewhere inside his chest cavity.
"I swear, I may have to chain you inside the safehouse whenever I leave." Z-69's expression cooled.
"I do not like chains."
"Good. Then stop buying things with pieces of your mind." Lumina tugged at Z-69's collar with one paw. Fear still sat beneath her anger. Next time, you are not entering that shop alone.
"I will try." The answer was diplomatic, noncommittal, and equipped with the kind of hidden exit Z-69 suspected he had used long before losing his memories. Even as he spoke, Z-69 knew it was hollow. He looked down at the short blade. Violet light reflected in his eyes while the weapon hummed warmly against his palm, resonating with the crystal in his chest. Sooner or later, he would walk through that door again.
The merchant had recognized him, the blade had waited across centuries he could not remember, and something inside the hollow places of his mind was already pulling him back. He did not know what. He did not know why. But this was not over. Z-69 walked through the alley with John following behind, still cursing under his breath. Lumina clung to his shoulder with renewed determination, her tail wrapped around his neck like a leash she intended to enforce. Neon flickered above them.
Garbage shifted beneath their boots. Yet something had changed. Z-69 carried a blade now. A blade that knew him. A blade that had waited. Somewhere beyond space, sense, and every law Crimeria still pretended mattered, the Faceless Merchant smiled behind his mask. Already preparing the next transaction.
