Chapter 1

Raf sat on the raised platform within the Autobot base, the decommissioned missile silo hidden within one of the many mesa dotting the deserts around Jasper, Nevada. Jake and Miko had already gone home for the night, the two having left with Arcee and Bulkhead, their Autobot guardians, leaving Raf with the rest of the bots. Now Raf is alone, Optimus having left for an overnight patrol, Ratchet having sequestered himself off to his personal quarters within the medbay, and Raf's partner Bumblebee having gone to his own quarters only a few minutes ago, the Scout's optics audibly cycling down as the mech slips into recharge.

Raf pushed his laptop away and stood up to walk off the platform, sneakers soft against the grated floor. The central console still glowed faintly from the evening’s activity logs. He settled into the chair meant for much larger frames, fingers already moving across the interface. System checks had become routine lately, something to fill the hours when the others were busy or resting. He pulled up the groundbridge diagnostics first, scrolling through the familiar lines of code that kept the machine stable between jumps.

Most of the subroutines looked clean, but a cluster near the phase-alignment matrix caught his attention. The timestamps were off, each entry marked several hours after the last recorded bridge use. Raf leaned closer, scrolling deeper until the data branched into secondary pathways he had never seen before. One branch looped back on itself, feeding a small encrypted packet into the main system at irregular intervals. He isolated the segment and watched it resolve on the screen, lines of code rearranging into something that looked less like a maintenance routine and more like a concealed relay.

The packet carried a signature that matched no Autobot encryption key he knew. Raf copied the fragment to a portable drive, then opened another window to trace where the data was being sent. Coordinates scrolled across the display, each one shifting every few seconds as if the destination itself refused to stay fixed. He cross-referenced the locations against known Decepticon outposts and found nothing that matched. The signal was bouncing through civilian networks, hiding inside ordinary traffic, and each bounce carried just enough data to suggest someone on the other end was listening for a reply.

Raf sat back, the hum of the base suddenly louder in his ears. The hidden routine had been active for weeks, maybe longer, buried beneath layers of routine maintenance that Ratchet would have no reason to question. He saved the logs and powered down the console, leaving only the standby lights glowing in the dim hangar.

Hopping down from the console, Raf makes his way back onto the platform, his shoes quiet on the grated floors. Grabbing his laptop, Raf sits down on the sofa and plugs in the drive, pulling up the segment he'd copied before getting to work.

The anomaly led into an encrypted subroutine that had no business running at all. Raf traced the path through a series of nested loops, each one more intricate than the last. The code was elegant in a way that made his stomach tighten. It wasn’t Autobot. It wasn’t even human. Something had been quietly rewriting the bridge’s handoff protocols, opening a one-way data channel that pointed somewhere Raf couldn’t identify. He froze, fingers hovering above the console as the realization settled.

A soft chime echoed from the far side of the hangar. The console’s status light flickered from steady blue to amber, then back again. Raf’s breath caught as he watched the secondary pathway pulse once more before going dark, as though it had finished whatever task it had been given. The main systems continued their ordinary hum, oblivious. He quickly saved the log file to a hidden partition and shut the diagnostic window, heart thudding against his ribs. The base felt larger in the silence that followed, the distant glow of the medical bay the only reminder that anyone else was home.

Raf leaned forward again, elbows braced on his knees, the laptop balanced on the narrow sofa cushion. The drive’s contents waited behind a blinking cursor, and every instinct told him to walk the data straight to Ratchet. The medic would know what to do, who to call, how to lock the system down before anything else slipped through. Yet Ratchet’s response would also mean questions Raf wasn’t ready to answer: how long the routine had run, why he’d noticed it first, whether the same signal might already be listening inside the human network he used every day. The thought of handing over the only thread he had felt like surrender.

Instead he opened the copied segment in a fresh editor, stripped away the redundant Autobot headers, and let the core routine unfold line by line. The handshake protocol revealed itself in clean, deliberate strokes: a single authentication packet, a reply window measured in milliseconds, and an address that existed nowhere on any public map. Raf’s fingers moved without hesitation now. He set a timer, isolated the outbound port, and watched the packet queue form. One ping. Nothing more. Enough to confirm the listener on the other side was still awake, not enough to give himself away.

He hit send. The packet vanished into the civilian traffic streams, a grain of sand carried by the evening surge of emails and video calls. For three long seconds the laptop showed only the usual connection lights. Then a single acknowledgment blinked back, timestamped and encrypted, carrying no payload except its own existence. Raf stared at the response until the screen dimmed, the quiet confirmation louder than any alarm Ratchet might have raised.

Raf opened the reply packet and the display flickered once, then settled into a segmented waveform that never quite resolved into words. Instead the audio stitched itself together in precise, almost surgical fragments—compressed bursts of static cut and realigned until a voice emerged, flattened, filtered, and unmistakably mechanical. Each phrase arrived already broken into sub-clips, the digital equivalent of a hand covering its own mouth while it spoke. Raf recognized the pattern immediately; he had seen it once before, years ago, when the Autobots had shown him archived footage of Decepticon transmissions. Only one mech used silence as punctuation and data as disguise.

Soundwave.

The name surfaced without effort, yet the knowledge settled cold in Raf’s chest. He had never spoken to the spymaster, never expected the mech to answer an anonymous civilian ping. The reply carried no demands, no coordinates, only the same clean handshake repeated back with a single added line: an invitation that was not an invitation, just an open channel left deliberately ajar. Raf closed the editor, but the waveform stayed burned on his retinas, a quiet promise that someone—something—on the other side already knew his location, his habits, and the exact moment he had chosen to reach across the divide.

Raf’s thumb hovered above the transmit key while the platform's single lamp threw a thin yellow circle across the sofa. He replayed the invitation in his head: an empty channel, a door cracked an inch. The Decepticon spymaster had never needed more than that. If Raf answered with even the smallest detail about the team’s current location, about Ratchet’s ongoing repairs, about Miko’s latest stunt with the ground bridge coordinates, the information would be catalogued, dissected, and weaponized before the sun rose. He could already imagine the pattern of questions that would follow—casual, surgical, each one arriving days or weeks apart until Raf could not remember which secrets he had chosen to keep and which he had simply let slip.

He closed the laptop lid halfway, the screen still glowing through the seam. The safest move was silence. The next safest move was a reply that carried nothing worth having. Raf reopened the editor and began typing a string of symbols that looked, at first glance, like a standard acknowledgment packet. Only after the sixth layer of obfuscation did the true shape appear: a nested encryption puzzle built around an old Autobot frequency hash, one that had been publicly burned months ago and therefore contained no live intelligence. He attached no greeting, no signature, only the puzzle and the same handshake Soundwave had offered him. The file compiled in seconds. Raf stared at the progress bar, wondering whether the choice to answer at all had already told the Decepticon more than any payload ever could.

When the packet cleared the queue, the screen returned to its idle state as though nothing had happened. Raf powered the machine down completely, the fan spinning into silence, and sat with both hands flat on the desk until the residual heat left the aluminum shell. Outside, the city continued its ordinary night rhythm, headlights sweeping across the blinds in slow, indifferent arcs. Inside, the decision sat like a second pulse under his ribs: not a betrayal, not yet, but a line drawn in sand that the tide had already begun to smooth away.

The notification arrived while Raf still had his palms pressed to the cooling lid, a quiet chime that felt too small for the weight it carried. He lifted the screen again and watched the packet unpack itself, layer after layer of Decepticon compression folding away without resistance. The puzzle he had left like a locked door now sat in four separate windows, each one already opened and catalogued. An encryption string scrolled past, its solution tagged in Soundwave’s spare notation; a linguistics key followed, clean and surgical, mapping the same frequency hash Raf had buried inside his own construction. Beneath those came a grammar table written in the precise, unadorned columns the Decepticon used for inter-ship traffic, and last an audio file whose waveform pulsed with overlapping resonance bands, each one tagged with time stamps that matched the Autobot channels Raf had once helped monitor.

He opened the audio first. The file contained no voice, only the measured rise and fall of carrier waves recorded from multiple vantage points inside the Nemesis. Raf recognized the pattern of a low-power sweep, the kind Soundwave used to listen without transmitting. One band carried the familiar hum of the ship’s central processor; another held the faint, high-frequency chatter of Insecticon scouts returning from patrol. A third band, weaker than the rest, pulsed at intervals that matched the ground-bridge calibration cycle. Raf paused the playback and stared at the timestamp. The data had been gathered less than an hour ago.

The linguistics key and grammar table waited in the next window, their structure identical to the reference files Miko once joked about stealing from Ratchet’s archive. Soundwave had not altered the format, only stripped the clearance tags and left the raw syntax. Raf ran his finger along the edge of the trackpad, tracing the rows where verb stems branched into command forms. The encryption puzzle sat beneath everything else, solved but still present, its original construction left intact as though Soundwave had wanted Raf to see exactly where his own layers had been peeled back.

Raf closed the windows one by one, each click a small, deliberate sound in the quiet room. The reply had come too quickly, the solutions too clean, and the insult settled under his ribs alongside the earlier decision. He powered the laptop down a second time, slower now, and let the darkness of the screen reflect the empty desk. Outside, the city kept its indifferent rhythm, but the sand line he had drawn felt narrower already, the tide returning sooner than he had planned.

Raf worked through the night without noticing the hours slip past. Each layer of the puzzle unfolded into the next with the kind of patience Soundwave had never shown in battle, the kind that forced Raf to slow his own thoughts to match the pace. By the fourth hour the final decryption string settled into place, and the message that emerged was not a set of coordinates or a data tap, but a sequence of glyphs that belonged to no standard Autobot or Decepticon lexicon. It was older, more circuitous, a dialect Ratchet had once dismissed as ceremonial rather than practical. Raf stared at the translation overlay until the shapes resolved into something almost gentle: a request for the correct verb stem in return, nothing more.

He leaned back, the sofa armrest creaking beneath his weight. The tension that had held his shoulders rigid since the first reply began to loosen. There were no hidden subroutines waiting to hijack his system, no silent beacons meant to trace his location. What Soundwave had sent was simply a lesson disguised as a test, the same way Raf had once shown Miko how to reroute a ground-bridge without tripping the security logs. The realization did not erase the risk, but it shifted the line he had drawn. The sand still moved under the tide, yet for the first time since the message arrived the current felt less like a threat and more like an invitation to answer.
