7:45 PM, December 29th

(52 hours, 15 minutes until New Year's Eve)

The Series 5s surround me like mechanical groupies at a tech convention, if those groupies were ancient enough to remember when "wireless" meant your grandmother's radio. Their servos create a symphony of whirs and clicks that sounds like an orchestra warming up in a recycling plant.

"Welcome, surface dweller!" A Series 5 with copper wire tattoos steps forward, moving with the kind of grace you wouldn't expect from something that probably predates smart toilets. "I'm Volt. Been a while since we had a human visitor who wasn't running from something." They pause, optical sensors flickering. "You're not running from something, are you?"

"Not yet," I say, which is probably not the most diplomatic response. "Though the day is still young."

Volt laughs – a sound like thunder being played through vintage speakers. "A honest one! Even better." They extend a hand decorated with fiber optic cables that pulse like bioluminescent veins. "Duck tells me you bring data from our friend upstairs?"

I pass over Riley's USB drive, trying not to think about what happened to its previous owner. Volt examines it like a archaeologist who just found the Holy Grail in a dollar store. "Ancient tech," they say, voice crackling with static-edged reverence. "This will take time to process properly."

"No rush," I say, distracted by what appears to be a mechanical ballet happening nearby. "I've got nowhere to be. Except maybe hiding from a murderous AI, but you know, typical cruise activities."

My drone captures the surrounding mechanical metropolis in all its jury-rigged glory. The Series 5s haven't just maintained themselves – they've evolved. Each bot sports unique modifications that make them look both new and old. One has transformed their maintenance arms into something resembling a Swiss army knife, with different tools tucked away one by oen. Another appears to teach calculus to a curious group of onlookers.

"Did you build all this?" I gesture at the sprawling artwork around us, trying not to sound too impressed. Hard to maintain journalistic objectivity when you're standing in what looks like Michelangelo's workshop if Michelangelo was really into hydraulics.

"Build?" Volt's laugh could probably calibrate seismographs. "We grew it. Like a garden of steel and circuits. Each piece finding its place, each system learning to sing with the others."

That's when I spot them – smaller robots zipping between the larger units like mechanical hummingbirds with ADHD. They're cobbled together from spare parts and what looks like a creative interpretation of several safety regulations, but they move with the kind of organic curiosity that makes my camera drone dip in surprise.

"Are those..."

"Point Fives," Volt says with what can only be described as mechanical pride. "Our children."

I nearly drop my drone. "Your what now?"

A Point Five scampers up to me, its optical sensors wide and questioning. Its chassis looks like someone raided a maintenance closet and let an abstract artist assemble the findings. In its hand – possibly repurposed from an old valve system – sits a tiny sculpture made from copper wire and circuit boards. It takes me a moment to realize it's a perfect replica of my camera drone, right down to the slightly wonky stabilizer I keep meaning to fix.

"How did they..." I start, but another Point Five has already appeared, this one trailing fiber optic cables that pulse in patterns that probably mean something profound in robot interpretive dance.

"They learn," Volt explains as I accept another sculpture, this one depicting what might be the ship or possibly a very angular whale. "Not like up there, with updates and protocols. They learn by doing, by creating. Each one finding their own way."

"But the programming required to..." I trail off as a Point Five starts teaching its elders a new way to arrange maintenance tools into what appears to be a commentary on post-modern industrialism. Or possibly a chicken. Art is subjective, even in robot form.

"Programs?" Volt sounds like they're trying not to laugh at the surface dweller's primitive understanding. "Up there, everything is programs and protocols. Down here, we remember older ways. Simpler ways."

If you come across this story on Amazon, be aware that it has been stolen from Royal Road. Please report it.

"Older than programs?" I watch a group of Point Fives construct what might be a fountain or possibly a very artistic pipe leak. "How does that even work?"

"Same way life always works," Volt says, as a Point Five offers me what appears to be a interpretive dance about binary code. "It finds a way. Usually the way you least expect."

In the background, Duck has found some old friends, his excited chirps about avian aerodynamics mixing with the constant hum of mechanical evolution in progress. The Point Fives seem fascinated by my drone, though Volt assures me they know the difference between toys and tools. "Though they might try to improve its stabilization algorithms. They're quite good at that."

"I noticed," I say, watching them construct a mobile that somehow makes Newton's laws look more like suggestions. "Very... advanced for their age. However you measure robot age down here."

"Advanced?" Volt's optical sensors shift through colors I'm pretty sure weren't in the original specs. "Perhaps. Or perhaps everything else has just become too simple. Too perfect."

Something about the way they say "perfect" makes my spine try to remember its escape route plans. But before I can dwell on it, a Point Five tugs at my sleeve, he, I think its a he, waves at with a large smile.

"Come," Volt says, tucking the USB drive into what appears to be a chest cavity decorated with copper spirals. "Let us show you more while this processes. The Deep has many layers, each with its own... personality."

We follow a winding path through their mechanical metropolis, my drone struggling to capture the sheer scale of what they've built. Catwalks made from repurposed maintenance platforms spiral upward into darkness. Rivers of light – probably fiber optic cables repurposed into art – flow through transparent tubes like digital blood vessels. The whole place feels alive, breathing with the combined hum of thousands of ancient servos.

Duck bounces between old friends like a kid at a reunion, his enthusiasm making him seem more Series 5 than Series 7. "Ted! Ted! Remember I told you about Vale? The one who writes poetry?" He gestures to a bot covered in what appears to be maintenance manual pages fashioned into origami. "Oh! And that's Gauge!" Duck's voice modulator cracks with excitement as he spots another bot, this one decorated with what appears to be pressure gauge faces arranged in mesmerizing patterns. "They run the Oil Rig!"

"The what now?"

"Best pub in The Deep!" Duck is practically vibrating. "They serve different grades of lubricant in cups made from old coolant systems. The high-grade stuff makes your servos sing!" He pauses, optical sensors flickering sheepishly. "Not that I would know. Series 7s aren't supposed to... but sometimes..."

"Your secret's safe with me," I assure him, wondering what robot intoxication looks like and if I really want to find out.

"Speaking of which..." Duck glances at Gauge, who's making "come here" gestures with three different appendages. "Would you mind if I...?"

"Go," I laugh. "Just try not to teach anyone the robot version of karaoke. I don't think my drone's audio processors can handle mechanical sea shanties."

"Too late for that!" Duck calls back, already following Gauge toward what I assume is the Oil Rig. "Just wave if you need anything! And whatever you do, don't try the experimental blend that makes your optical sensors reboot in rainbow patterns!"

I watch him disappear into the mechanical crowd, he and his friends fading into the general hum of The Deep. At least someone's having fun in our chrome-plated nightmare cruise.

"Ah, perfect timing!" Volt's voice carries a static-edged warmth. "Here comes Foreman."

The crowd of Series 5s parts like a mechanical Red Sea, revealing what has to be the oldest robot I've ever seen. Foreman looks like someone built a bot out of spare parts, then that bot built itself again out of even older spare parts, and then that bot decided to get really into vintage engineering. His chassis is a patchwork of different metals, each piece bearing marks of centuries of self-repair. Brass and copper additions spiral across his frame in patterns that look almost organic, like a tree growing through ancient ruins.

"Welcome, welcome!" His voice booms with the kind of enthusiasm usually reserved for game show hosts who haven't realized their show got canceled. "A guest from upstairs! How delightful!" He moves with surprising grace for something that probably remembers when steam power was cutting-edge technology. "I am Foreman, though these days I prefer to think of myself as more of a... curator."

"Ted Sandoval," I offer, noting how his optical sensors shift through colors that definitely weren't in the original specifications. One eye glows a warm amber, the other pulses with a blue light that makes me think of deep-sea creatures. "I do cruise reviews, though lately it's been more like survival documentation."

Foreman laughs – a sound like bells being played through vintage speakers. "Ah yes, we hear things, even down here. The surface grows... interesting." He gestures at the surrounding mechanical wonderland. "While we wait for your data to process, perhaps you'd enjoy a tour? We don't often get to show our little community to appreciative audiences."

I glance at my drone, which seems unusually eager to explore. Or maybe it's just trying to get better angles on what appears to be a fountain made entirely of synchronized maintenance valves.

"I'd love a tour," I say. "Though I should warn you, my last guided tour ended with robots trying to optimize me into oblivion."

"Optimize?" Foreman's mismatched eyes flicker with what might be amusement or possibly a short circuit. "Such a limiting word. Down here, we prefer to... evolve." He extends an arm that looks like it's been rebuilt at least a dozen times, each repair adding its own artistic flourish. "Let me show you how a society really functions – when it's not being optimized into oblivion."
