The glyph pulsed. A blinding surge.
Kaelen’s vision whited out. Sound died.
His mind screamed. Not pain, but *violation*.
Raw data slammed into his Primal cerebral cortex. No words. No images. Just a pure, undeniable *directive*.
*Designation: Primal. Core Subroutines Active. Locate and Retrieve: Core Fragment. Coordinates locked. Imperative: Absolute.*
His body seized. Muscles locked, then vibrated with an unnatural hum. A deep, resonant thrumming started in his sternum, spreading through bone and sinew. It was a low-frequency pressure, a silent roar echoing in his skull. His enhanced senses, usually a refined instrument of survival, became a crude antenna, straining, *reaching* for something far beyond the ravine.
His human intellect recoiled. *No.*
This was not instinct. This was programming. An override.
He was a strategist, not a puppet.
He fought it. He clamped down, trying to push the invasive data out. The hum intensified, a vibrating current running through his veins, making his teeth ache. The Primal form was responding, its very cells aligning with the new command. It was like trying to stop a tidal wave with a single hand.
The glow-moss. It hung heavy in his satchel, its bioluminescence a faint, familiar comfort against the alien invasion in his mind. He had risked his life for it. His tribe needed it. He had a mission. *His* mission.
But the Primal form didn't care for glow-moss. It cared for the *Core Fragment*. It yearned for it, a magnetic pull deep within his engineered biology. The coordinates flashed, not as a visual display, but as an innate *knowing* – a direction northwest, far beyond the familiar hunting grounds.
He stumbled back from the chasm wall, hands instinctively reaching to cover his ears, though the assault was internal. The glyph on the panel, no longer pulsing, now simply glowed with a dull, persistent light. It was an anchor, a transmitter. The command had been issued. It was now part of him.
*Absolute.* The final word of the directive resonated, a cold certainty.
Kaelen gasped for air, his twin hearts hammering against his ribs. He clawed at the ravine wall, scrambling away from the panel as if it were a predator. His powerful Primal legs felt foreign, twitching with the subconscious urge to run, to follow the invisible thread of the command.
He needed to think. He needed *silence*. But the hum persisted.
He scaled the rough-hewn path he’d descended, each handhold a small victory against the overwhelming impulse. The Razorback Lurker’s scent still clung to the air, a faint reminder of his earlier, tangible struggle. That fight, brutal as it was, now seemed simple, almost comforting. A clear objective. A clear enemy.
This was insidious. It was him against himself.
The climb was harder than it should have been. His focus fractured. Every tremor of rock, every rustle of dry vine, was filtered through the new, dominant directive. His eyes, usually sharp, kept darting northwest, seeking a path that wasn't there, trying to discern faint energy signatures that might guide him.
He reached the rim of the ravine, muscles burning. The sun, a pale, anemic orb in the Xylos Prime sky, cast long, distorted shadows across the desolate plains.
He stood panting, the glow-moss still clutched in his hand, a small, vibrant testament to his original purpose.
He had to get back to the tribe. He had to deliver the moss. That was his cover. That was his humanity.
The Primal mind, however, urged him northwest. The hum was now a persistent whisper, a low-frequency thought beneath all others. *Core Fragment. Retrieve.*
He forced himself to move, away from the ravine, back towards the distant plume of smoke that marked his tribe’s encampment. Each step was a conscious effort, a defiance.
The journey was a blur of internal struggle. He could feel his Primal form, the very essence of his engineered body, chafing under his human will. It was like trying to steer a wild beast while it had a single, overriding destination in its mind. His senses were simultaneously dulled and overstimulated. He registered potential threats, the movement of a Scavenger Flock high overhead, the rustle of a ground-crawler in the dry brush, but his reactions felt delayed, blunted by the internal conflict. He moved like a creature divided.
*What was this thing?* Kaelen’s human mind whirred, processing. A hidden protocol. A dormant subroutine. This planet wasn't just abandoned; it was *waiting*. And his Primal body was a key. A tool. A soldier.
He had been designed for territorial dominance. This command felt like an extension of that, but elevated. A higher-order territorial imperative. Not just to *hold* ground, but to *claim* something foundational to Xylos Prime itself.
If this command was absolute, could he even fight it? What would happen if he ignored it? Would his body malfunction? Would his Primal form rebel outright, taking over, forcing him to comply? The thought sent a chill down his spine. His carefully constructed mimicry, his hidden intellect, all of it could unravel in an instant if his body betrayed him.
He reached the scrublands bordering the tribe's territory. Familiar landmarks emerged from the gloom: the crooked spine-tree, the weathered rock formation shaped like a gaping maw. The scent of woodsmoke and roasting game drifted on the wind. Home. Or at least, his current imitation of it.
The hum within him did not lessen. If anything, it seemed to intensify as he drew closer to the perceived safety of the tribe, as if the Primal programming recognized an obstacle to its objective.
He moved cautiously, slipping through the perimeter, just as he always did, maintaining his Primal persona. Head down. Sniffing the air. A low growl vibrating in his chest, a sound that now held a double meaning.
A young Primal, barely out of its pup-stage, darted across his path, chasing a scuttling ground-beetle. Kaelen almost snarled, an uncontrolled flash of aggression rising from the depths of his overridden mind. He caught himself, forcing the surge back down, instead letting out a guttural rumble of warning. The pup yelped and scrambled away.
*Control. You must control this.*
He made his way to his den, a shallow depression beneath an overhang, hidden by thick, thorny bushes. He carefully placed the glow-moss inside, its faint light casting an eerie pallor on the rough-hewn walls. He had completed his task. Now he needed to report.
He emerged from his den, heading towards the central gathering fire. Elders clustered there, their hides scarred, their eyes keen. The Alpha, Krall, would be there, his immense form dominating the space.
As he approached, a younger scout, Jorn, intercepted him. Jorn, whose scent-glands often betrayed his aggressive curiosity.
"The moss," Jorn grunted, his eyes narrowing, catching the lingering scent of the ravine and the Lurker. "Did you find it?"
Kaelen nodded, a deep, rumbling sound escaping his throat. "Secured."
Jorn’s gaze lingered on him. "You reek of fear. And something else. Strange."
Kaelen tensed. Had Jorn sensed the internal struggle? The alien hum?
"Lurker," Kaelen rumbled, forcing a primal disdain into his voice. "Weak. But messy." He subtly shifted his weight, his stance a silent challenge. *Back off, pup.*
Jorn seemed to accept the explanation, though a flicker of suspicion remained in his dark eyes. "Give the moss to the Healer. Then report to Krall."
Kaelen nodded again, a slow, deliberate movement. The Core Fragment hummed. *Northwest.*
He headed towards the Healer’s den, a crude shelter built into the base of a massive, petrified tree. The Healer, an ancient, wizened female Primal named Lyra, meticulously sorted herbs and poultices. Her senses were legendary, almost preternatural.
He approached cautiously, offering the satchel of glow-moss. Lyra’s clawed hand reached out, her fingers brushing his.
Her eyes, ancient and clouded with age, fixed on his. They were the color of stagnant pond water, but they seemed to pierce through his very being.
"You carry a heavy shadow, young one," Lyra rasped, her voice like dry leaves skittering across rock. Her nostrils flared, drawing in his scent. "A song of discord. A call that is not our own."
Kaelen froze. His hearts hammered. She knew. Or she sensed it.
He kept his expression blank, a carefully cultivated mask of primal indifference. "The ravine is deep. And old." He tried to deflect.
Lyra’s gaze did not waver. She took the moss, her touch lingering on the satchel. "The chasm holds ancient things. Things that stir in their slumber." She paused, her voice dropping to a whisper. "And sometimes, they awaken echoes in those who listen too closely."
She pulled her hand away, her fingers twitching. "Go. Report to Krall. But remember this, Kaelen. A borrowed song can lead one astray. Or betray the singer."
Kaelen dipped his head, a silent acknowledgment, trying to hide the tremor that ran through him. He turned, the hum now feeling like a roaring furnace in his core. Lyra’s words were a warning, a validation. The secret was already straining at the edges of his control.
He walked towards Krall, the Alpha’s massive form silhouetted against the central fire. The other Primal warriors sat or stood nearby, their eyes occasionally flicking towards him. He was being watched. He was *always* being watched.
He approached Krall, stopping a respectful distance away. Krall’s eyes, the color of obsidian, were fixed on the dancing flames. He did not immediately acknowledge Kaelen. This was a test of patience, a display of dominance.
Kaelen waited, fighting the urgent thrumming of the Core Fragment directive. His human mind raced, analyzing Lyra’s words, processing the implications of the command. This was more than a hidden protocol. It was a potential existential threat to his disguise, and perhaps to the tribe itself.
After a long moment, Krall slowly turned his head. His gaze was heavy, weighing. He grunted, a deep, rumbling sound that vibrated through the ground. "The moss?"
"Retrieved," Kaelen rumbled, maintaining eye contact, forcing his Primal pride to the surface. "Lurker dealt with. Deep in the canyon."
Krall’s gaze sharpened. "Deep? What did you find there?" His voice was a low growl, laced with a predatory edge.
Kaelen's entire Primal body went rigid. *This was it.* He had to choose his words with extreme care.
He couldn't lie about *nothing*. That would be suspicious. He also couldn't reveal the panel, the glyph, the command.
"Old stone," Kaelen rumbled, keeping his tone even, dismissive. "Strange markings. Faded. Dead." He made it sound like an unremarkable, ancient ruin, something of no threat or value. "The canyon holds only echoes now."
Krall’s eyes narrowed further, searching Kaelen's face, his posture, his scent. The Alpha was a master of reading his kind. Kaelen tried to project boredom, a primal dismissal of useless ancient things.
The hum of the Core Fragment intensified, a desperate, silent plea from his very cells. His body wanted to contradict him, to confess the truth of the activated glyph.
Krall held his gaze for a long, agonizing moment. Kaelen felt a bead of sweat trickle down his temple. The Alpha seemed to search for a falsehood, a weakness.
Then, Krall slowly turned back to the fire. His immense shoulders relaxed slightly. "Good," he grunted, the single word a dismissal. "You did well. Rest. There is hunting tomorrow."
Relief washed over Kaelen, so potent it almost buckled his knees. He bowed his head, a gesture of respect, and began to back away. He had survived the immediate interrogation. His cover remained intact.
But the Core Fragment hummed louder than ever. It was pulling him. Demanding.
He moved away from the fire, blending into the outer circle of Primal forms, his mind already plotting. He had to honor the moss delivery. He had to maintain his persona.
But he also had to understand the command. He had to find out what "Core Fragment" meant. What was this artifact, and why was his body being forced to retrieve it?
He cast a surreptitious glance towards the northwest, the direction the command indicated. A jagged peak, shrouded in perpetual mist, rose far in the distance. The Spine of the World, the tribe called it. A place of myth and danger.
The hum became a siren song, promising answers, promising a revelation about his own existence. He knew what he had to do.
He would follow the command. He would hunt the Core Fragment.
But first, he needed a reason to leave the tribe, a plausible explanation for a detour into the Spine of the World.
His gaze swept the encampment, searching for an opportunity, a weakness, a strategic advantage.
He saw it.
On the far side of the central fire, nestled among a pile of furs, lay Krall’s youngest pup, whining softly. Its leg was bent at an unnatural angle. Lyra, the Healer, knelt beside it, her brow furrowed in concern. Her hands glowed faintly with stored bioluminescent moss, but the pup’s whimpers did not cease.
They needed something more. Something rare. Something found only in the deepest, most dangerous parts of Xylos Prime. Something near the Spine of the World.
Kaelen’s human mind clicked. The perfect cover.
He watched the pup writhe, then looked up at the Spine of the World.
His path was clear. And deadly.
