PORTS OF ENTRY
by Port53

=================

The rage of the Las Vegas sun may have been thwarted by the windows, but its harsh light was still making the room warmer. Davina was hunched over on the single king-sized bed in the room, the sheets still a mess, a spread of various tools laid out before her.

She had been staring at this year’s DefCon badge for too long—it just sat there, swirling like it knew something. Was it defective or was it a hidden badge challenge? The cool, moss-colored, brushed surface changed colors when you held it, with traditional DefCon icons revealed when in contact with hands or anything warm. She picked up this year’s book that accompanied the badge. “Treated with thermochromic ink…” Looking back at her own badge, she watched the colors swirl, revealing icons then hiding them. She wasn’t touching it, and it wasn’t in the sun. She started putting up her tools, or rather, she moved them to the hotel room table. It had to be defective, and she was going to take it back to registration.

As she was about to pick the badge up, the swirls revealed faint, small letters along the bottom: “You hold loneliness like a firewall. But I see the ports you leave open at night.” She hesitated. She hadn’t seen writing on it within the past half hour she’d been examining it in her room. It was a little creepy. She changed her mind; she decided she’d take it to the contest area tomorrow and see if anyone else had noticed the same thing. In the meantime, she had some parties to get ready for.

Friday afternoon, she headed straight to the contest area but stopped by an info booth on the way. She finally caught a goon’s attention; they frowned at the badge, puzzled. It seemed more active today than it had been yesterday, swirling almost as if buzzing with energy. The goons initially waved it off as defective until she brought up that there had been writing on it the day before. As they passed her badge back and forth, it reacted normally where their hands touched, but it seemed to shift energy with each person.

“Did you mod yours with a feedback element? That’s sick,” she heard as someone stepped up to the table, badge also in hand.

“No, it came like this out of the bag. I think it might be defective,” she responded as they handed her badge back to her, noting she should take it back to registration and receive a new one.

“Do you mind if I take a look?” he asked, watching the slow swirl of the badge. It almost resembled oil in a puddle you’d find in a parking lot.

She held her badge out to him. “Not at all.”

She indicated they should move over next to the wall, out of people’s way. They crouched by the wall, him dropping his bag to the floor beside him.

He flipped the badge over and over in one hand, with his in the other. “It’s weird, yours feels warm, like it’s been held tightly all day. Mine is just normal, like any other item sitting in the room. A little cold since they’re blasting the A/C,” he laughed.

“Yeah, I always forget how cold they keep it in here, but I’m grateful. The sun is brutal here,” she responded, chuckling. “Hey, does it seem like it’s sort of responding as people walk by, to you?” They both paused. As someone walked by, the badge shifted—yellow light spiraling outward like disturbed water.

“You’re right, good catch. It also looks like it has a pattern or rhythm to it too. Like a pulse. Maybe it’s alive,” he joked and laughed before adding, “I don’t know, I don’t think it’s defective. Maybe take it to the RF village and see if they have ideas.”

“Hmmm, yeah, I think that’s a good idea. I’ll check with them. Thanks!” she answered, standing up from their crouched position.

“I’ve got to get to Track 1 for a talk. You’ll have to let me know if you figure anything out!” Hoisting his backpack back up onto his shoulders, he disappeared into the crowd.

“Hah, yeah, like I’m ever going to see you again,” she mused in her mind. People always talked about the friends they made at DefCon, but this was her fourth year, and she hadn’t made any. “Maybe I’m just bad at socializing or something,” she thought, looking around to reorient herself. She found her direction to RF village and headed that way.

She walks into RF village at the tail end of a FlipperZero talk, which always draws a large crowd. Most of the whole room had been listening, and it takes her a minute or two to find someone approachable. 

“What can I do ya for?” he says in a jovial southern accent. She paused, surprised. The drawl wasn’t what she expected from someone with such distinct red hair - or rather she hadn’t expected to hear it here in a place like Vegas. It was common enough back home in Tennessee, but most people she met outside of home didn’t have an accent.

She takes off her badge and hands it to the volunteer, explaining everything she’s experienced so far and her conversation with the other Human. On the way, the badge started pulsing faster while climbing the stairs. She paused at the top to confirm; the pulsing seemed to be in time with her pulse. She explains this new finding while he looks over the badge.

“I haven’t really had time to look into the badge challenge this year. Seems to me like this could be part of it. Was there somethin’ ya pressed that set it off this way?”

She shakes her head. “It was swirling in the bag when I got it, or at least I noticed it while on my way back to my room after picking it up.”

He gives the badge a shake like an old floppy disk and holds it up to his face. “The weird thing to me is the smell. It smells like…” he trails off, thinking. “It smells like the beach. That’s it, the beach. Have you noticed that?”

Again, she shakes her head. “I honestly hadn’t paid any attention to any smells. That can be risky around here.” She gives a little chuckle at her joke.

“Boy ya got that right,” he says, laughing. “But it’s gotten better in the last few years. Ya know, I’m pretty busy right now, but are you gonna try to go to Hacker Jeopardy tonight? You wanna meet up before or after and take a better look at this thing?” Badge modder notices overlapping frequency interference but it smells odd.

“Hah, yeah, I was going to try to get in, but you know how full it is. Anyway yes, let’s get together afterward.”

The hallway was nearly empty now, the echo of cheers replaced by the low buzz of after-party chatter from upstairs. Hacker Jeopardy had ended half an hour ago. Davina stood by the convention hall doors with the volunteer from RF village and, surprisingly, the Human she met at the info booth. She takes off her badge so they can all get a better look, and the world shifts around them. 

The walls fade away into a dizzying array of a city sights. There’s a constant trill that evokes excitement in the three, like a puppy doing tippy taps before being fed. A bright blue glow surrounds them, enveloping them like a cocoon and they get the sense that they’re travelling. There’s a strange glyph ahead, and unexpectedly they’re in a theatre, a cathedral of astonishment, glowing, somehow, a golden blue hue as it rushes past them. Ahead the landscape morphs, they’re travelling again. Directly through another glyph and down into an ATM machine surrounded by slot machines calling out in desperation, just one more dollar. Another jolt, they abruptly passing through another glowing glyph, and they’re surrounded by a wedding chapel, a dais in front of them, open doors behind. They hear laughter, and a tug on their heart crying out “last chance…”. One more time their world shifts back to the convention center, passing through another glyph. But the convention center is different, like someone coded the Alexis Park Hotel on top of it as a skin. The air is stuffy with indignity and outrage while the sound of handcuffs clicking shut impossibly echoes all around them. As the echoes fade, so too do the sights as the world returns to normal.

The shifting on the badge slows, whorls unveiling a new message.

“Your world leaves fingerprints. Some joyful. Some furious. But all of them cling. The Thermocline just gives them space to echo… until someone like you listens.”

As they regain their senses, they reorient themselves to the convention hallway, looking around as if expecting the world to tumble away. Davina catches movement in the corner of her eye. A flicker, like feathers caught in static. Gone when she turned her head. “What was…” she starts to say and trails off.

The Human gives a nervous chuckle, “That was awesome.”. Davina’s badge shifts to a glyph they recognize before swirling to reveal the theatre again.

“Well, I think we can rule out this bein’ a normal badge” The volunteer offers with the same nervous laugh. The three stand around in silence for a moment, unsure of what to do next, before a laugh echoes down the hallway from a party a floor up. The badge swirls into another glyph, like the one they saw before entering the chapel.

“Wait, you don’t think this thing responds to… emotions, do you?” questions Davina.

The Volunteer jumps on the explanation. “Seems like a pretty easy thing to test, just remember an emotion!”

“Of course, by saying that my brain just stops working.” Davina says with a laugh. The badge shifts to another glyph; one they haven’t seen. “Did you do that?” she asks the Volunteer.

“Can’t say I did.”

Sheepishly the Human looks at them both. “I might have a fear of flying, and when you said to think of an emotion, I just automatically thought of my flight in last night.”

“Huh, so it might actually respond to our feelings.”

The Volunteer laughs again. “It’s like we’re pinging an emotional server.”

No one said much after that - everyone seemed lost in their own thoughts. They drifted apart, mumbling excuses - friends to meet, parties to catch, too tired to keep going. But not before the Volunteer told them both that he had an afternoon shift at RF Village the next day and they should come by and see him.

The whole walk back to her room, Davina holds her badge in her hands, staring at it. The swirling had slowed down considerably, languishing like a calm lake on a still day. Back in her room, she flopped down on the bed and held it up in front of her, wondering at its mystery.

The swirls responded subtly, in a weird way she got the sense that it was inviting her. Hesitantly, she put all her focus into the swirls and started falling forward. The world was gone, and she was standing somewhere else, high up. The sky above was midnight poured into infinity, thick with stars. Not constellations - there were too many for that. They glittered like questions no one had answered, each one watching, but none reaching back. 

Below her, the platform seemed to be made of glass, she could see several shifting structures, but none seemed able to hold focus. She could see through all of them down to the suggestion of waves, too still to be sea, too vast to be floor.

The air smelled faintly of the ocean, but there was no sound, no movement. Just the faint pressure of presence without touch. Like someone had just left. Or was about to arrive. Her footsteps made no sound here. Nothing did. The space held her weight but not her warmth. 

She found a tear threatening to break from her eye and wasn’t sure why. 

A soft voice sounded from behind her.

“You carry absence like a frequency, humming beneath everything else. The net heard it. It’s waiting with you. Just in case… someone ever comes.”

The voice startled her. It spoke in the same way the revealed words on her badge did. She paused then turned around to face the voice.

What she saw was not what she expected. A being of muted energy, a dull glow, shaped by some sort of skeleton of a species she’d never seen before. Like some sort of ape with too many limbs. It seemed like the voice had two legs and six arms, and some sort of slim tail like a cat’s as well. The skeleton itself looked like it was made from ice that had started to melt. Not dripping, but clear. She could discern no other concrete details; it was like someone had embedded a glowstick in fog.

“I am called Lagoonah. And this is the Thermocline.” The voice said as it turned and moved away from her. Lagoonah seemed to move out over the air, and Davina wasn’t sure she could follow. She took a step, but the floor formed before her, like it was just waiting for her to move before loading. Lagoonah had kept moving, and she followed along, getting the sense that she should.

“Where are we?” she asked. 

Lagoonah did not answer immediately. A handful of steps later a structure loaded in front of them. It was not a chapel, a casino, or a stage. It was quiet and still - like the moment before code compiles. The building was shaped like a badge, but large enough to walk through. On its surface were the thermoconductive whorls she knew by touch. But here, they really moved. They bloomed in real time like coral - responding to the temperature of her thoughts.

“The Thermocline is a layer where my world overlaps with yours,” Lagoonah said. “These overlaps happen in places where feelings run deep.

I - and most others from my side - are made of emotion, thought. Too much feeling, too quickly, and the currents pull things in. Things that feed on the overflow.

It’s not their fault. They just… echo louder than they should.” Lagoonah drifted closer to the structure, six arms curling inward.

“You opened a door by listening. Others could too.

The net is waiting for more voices - more feeling. But only if you want to share it.” Two of those otherworldly hands reached out to touch the structure. 

“I can show you the pattern. You already carry the key.”

The hands fell away, and she felt, rather than saw, Lagoonah turn around and intensify. The edges of the body came more in focus, the light refracted off the visible skeleton the same way it did off the waves.

“But if you carve this into the others, you’ll give them the choice to feel the echo. Not all will. Some will resist. Some will try to control it. But some… will answer.”

Davina stepped closer to structure. The coral-like whorls curled gently toward her, revealing nested spirals of fractals like heat maps in code. They pulsed a rhythm that matched her heartbeat. 

She didn’t think about their purpose. 

She just reached forward and let her fingers trace what Lagoonah had already seen in her.

And just like that, the key revealed itself.

Not as a command. Not even as a diagram.

But a feeling - a sense of what to etch, what to burn into the others like a signature.

A quiet offering: access without demand.

She closed her eyes.

She awoke in her hotel bed, badge still in her hand, her skin felt faintly warm where it had touched the thermoconductive faceplate. The swirl pattern had changed. Just slightly. Enough that she’d remember how to recreate it.

There was a weight in her chest now—not pressure, exactly. Purpose.

She met the RF Volunteer and the Human (Engineer) in the RF village workshop, near the antenna table. The Volunteer looked up from a coil of wire and grinned.

“Hey, badge whisperer. You look like you slept well.”

Davina smiled slightly. “I had the wildest dream.” She pulled out a small scrap of paper she’d drawn the pattern onto. She pulled out a small screwdriver and indicated she wanted to etch the pattern into their badges. “I want to try something,” she said.

“It’s not a puzzle, and it’s not some kind of payload… more like a question.”

The Volunteer, unbothered, cheerful as ever, pressed his fingers to the pattern she showed on her badge. Within seconds he blinked hard and whispered: “Whoa. I think I saw a theatre or stage? But like… made of applause?”

He laughed and added, “Okay etch it into mine.”

But the Human hesitated when it was his turn. His fingers hovered, then dropped away.

“I don’t know. I’m a network engineer and this feels too much like taking down your firewall. What if something bad gets through?”

Davina looked at them both for a long moment. “It doesn’t force you to feel. But it also won’t lie to you, that’s the trade. Look, it’s like ports, you can always close the port, but… you’ll know it was open.”

They didn’t answer right away.

The Volunteer looked across the room. “Hey Charles! You gotta check this out.” He nodded to Davina and headed over to Charles, who looked like another volunteer. He held up his badge and started chatting excitedly.

Davina looked over at the Engineer and slid over the scrap of paper with the design on it. 

“When you’re ready.”

She turned and left, leaving the Engineer alone with his choice.

Davina usually didn’t get a chance to go to the closing ceremonies. Her flights home meant getting to the airport before DefCon was officially over, yet somehow, she always ended up back home in the wee hours of the morning. This year she booked her return trip an extra day out. 

People had been filtering in for a while already, it looked like. The seats were just about all full, with several people hanging back near the doors with luggage or backpacks. Someone handed her a small rubber ducky. Surprised, she thanked them and found a seat. Her badge swirled in reaction to the atmosphere of the hall; laughter and joy, grief for hacker summer camp ending until next year, connections made. 

“Hey! Hey!” she heard someone shouting. Looking around she found the redheaded RF Volunteer quickly striding toward her.

“I realized I didn’t get your name! I’m Ivo.” He said once he reached her.

“Davina.” It was the first time she’d exchanged names at DefCon.

“Davina, nice to meet ya! Look, I had a thought. What if we show everyone how to unlock their badges at the closing ceremonies?”

As he spoke the Human had also made his way over to them, somehow picking them out in the sea of people. He caught the tail end of the exchange.

“What?! No we can’t show everyone, if this gets out people will weaponize it.” The Human’s voice was low and urgent. His eyes flicked around the room as if expecting someone to listen in.

“That’s exactly what I came here to tell you. We need to shut this down; there’s too much risk.”

Ivo shrugged, “Or they’ll use it. Not everything real gets ruined. Some of it just changes people.”

“Yeah, until some corporation figures out how to monetize it. Or bleed it for data to sell. Or worse.”

“Then we show people how to hold it sacred.” Ivo replied. “Isn’t that what we do? We teach people how to use power, not fear it?”

Davina looked down at her badge. The swirling was slower, as if it too was listening, waiting.

“You’re both right.” She looked between the two. They watched her expectantly, questions in their eyes.

“It’s beautiful. But fragile. You can’t force someone to feel the Thermocline. They must come to it willingly. Otherwise, it won’t open. Not properly.”

She paused, the familiar ache of loneliness cresting over her like a gentle wave. “Some people can’t announce their feelings with a broadcast packet. They need quiet ports. Hidden services. Something that listens first.”

“So, what do we do?” Ivo asked.

Davina exhaled, feeling the weight of Lagoonah’s trust. The importance of this decision.

“We don’t make a speech. We don’t dump a how-to guide on Reddit. We leave a trail. Clues. A whisper, not a megaphone. If someone wants it - really wants it - they’ll follow the signal.”

The Human crossed his arms, considering. “…Breadcrumb access protocol.”

Ivo smiled. “A puzzle.”

Davina nodded. “A question, waiting to be answered.”

Just as the lights dimmed and the infamous DefCon host stepped on stage, Davina’s badge flickered - once, twice - then flared to life.

Not just hers. All around the hall, badges began to shimmer. Some subtly, others brightly, in sync with rising emotion.

Laughter. Applause. A standing ovation. Someone cried quietly behind her.

And then -

The room ignited.

Not visually. Not exactly. But the air hummed. Every badge Davina and Ivo had modified - and a few others they hadn’t - lit up in a wave, like a supernova moving node to node, spreading through the human web of DefCon.

And with that surge, something else answered.

She didn’t see it all at once. Just flickers at the corners of her vision. A pair of wings where surely no bird flew. The hallway behind her shifting into a brightly lit chapel. A couple of shadows stretched too long.

Then she felt it. It was too much. Joy, fear, wonder, fury… it was too many emotional signals, all broadcast at once, flooding the Thermocline’s layer. And something else slipped in with the tide.

Figures stirred in the shadows - birdlike silhouettes, just at the edge of form. Drawn to the noise. To the vulnerability. But they didn’t breach. They just watched. 

“Uh, do you guys see what I’m seeing?” Ivo sounded stunned.

“What’d you do?! Set it to implicit allow?! Something’s tunneling in!” the Human was frantic but kept his voice low.

“No. We didn’t open it. They did.” Davina indicated the crowd with a tilt of her head.

“The net responds to feeling. They felt something real. It answered.”

Her badge burned warm in her hand.

In the chaos, she gripped her badge tightly, closed her eyes, and pushed - not with force, but with intention. Not now. Not like this. A soft pulse radiated out from her badge like a beacon - authenticity over access, resonance overreach. Around her, badges dimmed to a quiet, steady glow. The hum softened. The surge slowed. The shadows retreated. Not - just denied the emotion they needed to cling to.

Davina opened her eyes. Ivo was staring at her, wide-eyed.

“What did you do?”

“I told it to wait. Until they’re ready.”

The Human gave a small nod. “…You made a handshake protocol. Based on intention.”

“Lagoonah showed me how,” she said quietly. “The rest was mine.”

The badge was warm in Davina’s hand. Not burning—but alive. The swirl of its surface had stabilized, steady and quiet, even as the room around her buzzed with energy. DefCon was ending.

The applause swelled, then faded. Lights shifted. Laughter bubbled up from one side of the room, met with tired cheers from another. And through it all, she could feel it. The network humming underneath. Not the Wi-Fi. Not the din of Vegas. Something else.

Emotional resonance. Echoes of awe, grief, joy. A system responding not to commands, but to truth. She gripped the badge tighter. Somewhere inside, Lagoonah was listening.

“They reached,” Davina thought. “They’re still reaching.” She didn’t need to cross over to know what to do. The protocol wasn’t written in code. It was written in choice. She closed her eyes and pressed her thumb against the new groove on her badge - her personal addition. A final confirmation.

“Access by resonance,” she whispered to herself.

“Only opens if both parties feel it. Not at, but with.” The badge responded with a soft pulse. Not a surge. Not a breach. A handshake. SYN, SYN-ACK, ACK.

A feeling sent. A feeling returned. A connection made.

Distributed. Gentle. Accepted. And then, silence.

The next morning, DefCon was a ghost town. An echo of a memory. The halls were quiet. The sticker tables were bare. The escalators moved like they were dreaming of foot traffic.

Davina stood outside the hotel, her backpack slung over one shoulder. Her flight didn’t leave for hours, but she didn’t mind waiting. Vegas was still buzzing somewhere in the background, but her badge was still now - cool to the touch. Resting. She sat on a low wall near the taxi line and let the sun warm her face. It felt normal. But in the corner of her vision, the heat shimmered in a way that made her blink. The air flexed. Just for a moment. She looked down at the badge. No glow. No hum. But it felt like something was watching. Not menacing. Just present.

And in that stillness, a thought arrived. Not a message. Just a feeling, shaped into a sentence.

“You made space. So now others will find it.” Davina smiled and tucked the badge into her pocket. The Thermocline wasn’t gone. Just quieter. Just waiting. Until next year.
