Adam’s Cave – Late Morning
The sun was already high, its golden light filtering through the canopy in thick, slanted shafts that painted the jungle floor in dappled patterns of emerald and gold. Adam stirred slowly, his body heavy with the kind of profound, bone-deep satisfaction that came only from a night of vigorous exertion. He reached out instinctively, his hand searching for the familiar warmth of Eve’s body beside him—the soft curve of her hip, the silk of her hair, the gentle rhythm of her breath.
His fingers found only empty moss. The absence jolted him. His crimson eyes snapped open, scanning the area in front of the cave mouth where they had fallen asleep beneath the stars. The fur cloaks were rumpled, the remnants of their lovemaking still evident in the disheveled bedding. But Eve was gone.
“Eve!” he called out, his voice rough with sleep and rising panic.
The jungle answered with only the distant calls of birds and the rustle of leaves in the morning breeze. Adam sat up sharply, his heart beginning to hammer against his ribs. His mind raced through possibilities—apes returning for revenge, a predator that had slipped past their defenses, the T-Rex reneging on their truce. The visions of violence cascaded through his consciousness, each more gruesome than the last. He saw her broken body at the bottom of a ravine. He saw her torn apart by raptor claws. He saw—
Then he noticed it. Her clothes were gone. The deerskin bra and fur loincloth that had been piled haphazardly next to his own garments the night before had vanished. Adam’s racing mind began to slow, logic reasserting itself over primal fear. If she had been taken, her clothes would still be here. She would not have had the opportunity to dress herself. The fact that she had taken the time to don her garments suggested awareness, intention, and autonomy.
He rose to his feet, his bare soles pressing into the cool moss as he scanned the ground. His enhanced eyesight picked out the faint impressions in the soft earth—bare footprints, delicate and light, leading away from the cave and into the underbrush. They were subtle, barely visible to anyone without his acute perception, but they were there. She had walked away on her own two feet. But why? Where would she go alone?
A soft scuffling sound drew his attention. Toothy emerged from the cave’s interior, his massive frame filling the entrance. The sabertooth’s amber eyes were bright and alert, his movements fluid and powerful. Behind him, the smaller pets emerged—Nutty’s russet tail twitching, Squeaky’s striped body scurrying over the rocks, Tiny’s whiskered nose twitching as he investigated the empty bedding.
Adam’s gaze returned to the tiger, and he noticed something remarkable. The wounds that had plagued Toothy since his battle with the giant ape—the deep gashes and torn flesh—had all but vanished. His coat was sleek and full, his muscles rippling beneath the golden-striped fur with renewed vigor. The animal moved without the slightest trace of pain or stiffness.
“You’re looking well, my friend,” Adam murmured, crouching down to examine the tiger more closely. “Rested. I think my blood really does have healing powers.”
Toothy stretched languidly, his spine arching, his claws extending and retracting in a display of pure feline contentment. He opened his massive jaws in a yawning roar, a sound that rumbled through the clearing like distant thunder. The gesture was one of vitality—a demonstration of his returned strength. He padded forward and nudged Adam’s hand with his broad, wet nose, demanding attention.
Adam obliged, his fingers sinking into the thick fur behind the tiger’s ears, scratching rhythmically. Toothy’s purring intensified, a deep, resonant vibration that Adam could feel in his own chest.
The smaller pets chittered anxiously, their high-pitched voices filled with concern. Nutty scampered up Adam’s leg and perched on his shoulder, his tiny claws gripping the muscles as he looked toward the jungle. Squeaky and Tiny followed, their bodies trembling with nervous energy as they searched for the familiar scent of their mistress.
“Come along, little ones,” Adam said, his voice grave. “Your mother is out on her own. We must see to her.”
He gathered his fur loincloth from where it lay crumpled on the moss, tying the leather cords around his waist with practiced efficiency. His expression hardened as he turned toward the trail of footprints leading into the dense foliage. A flicker of irritation sparked in his chest, growing steadily as he began to follow the tracks.
Why would she do something so reckless?
The question circled in his mind like a vulture over carrion. True, the jungle was safer now. The ape tribe had been decimated, their stronghold reduced to a charnel house. The raptors had entered into an uneasy truce. The T-Rex owed them a debt of blood and healing. But there were still countless dangers—quick predators that moved in silence, venomous serpents coiled in the underbrush, territorial beasts that had no quarrel with the dinosaurs but would gladly make a meal of a lone human female.
What could that fool woman be thinking, going off on her own like this? And then there was the matter he had not yet shared with her. The memory of that single drop of milk on her nipple, the sweet and nutty taste on his tongue—it was proof. She was carrying his child. His heir. A new life that would one day walk this savage world.
She didn’t know yet. He had chosen to let her sleep, to keep the revelation for a moment when they could share it together in peace. But now that knowledge weighed on him like a stone. Eve was out there, wandering alone, completely unaware that she was responsible for another life besides her own. If anything happened to her now...
Adam’s jaw tightened. He would tell her the moment he found her. And perhaps then she would be less inclined toward such stupidity.
He pushed through the underbrush, his long strides eating up the distance. Toothy moved silently beside him, a golden shadow in the dappled light. The smaller pets kept pace, darting through the low branches and fallen logs that lined their path. They traveled for miles, the jungle growing denser and darker as they moved away from familiar territory.
Adam’s irritation simmered, but beneath it, something else began to stir. He recognized this part of the jungle—or rather, he recognized its proximity to somewhere significant. The terrain was unfamiliar, yes, but it stirred something deep in his memory. A sense of déjà vu, of latent recollection.
This area was not far from where he had first awakened. He estimated the distance—perhaps a few miles to the north, near the base of the towering mountains whose white-capped peaks were visible above the canopy on clear days. That region also bordered the territory where the mammoth herds typically grazed during the warmer seasons. Had Eve somehow connected the dots? Was she investigating the reason for their unusual migration?
The thought gave him pause. If she was tracking the mammoths, it meant she was thinking strategically—trying to understand what had driven them from their normal grounds. It was the kind of analytical thinking he had been trying to teach her. But it didn’t explain why she would go alone, without waking him, without telling him her plan.
After what felt like hours of tracking, the jungle suddenly opened into a small clearing. The sunlight here was brighter, unobstructed by the thick canopy that had shadowed their journey. Wildflowers dotted the edges of the grassy expanse—purple and yellow blooms that swayed gently in the breeze.
And there, standing in the center of the clearing, was Eve. She was dressed in her deerskin bra and loincloth, her golden hair catching the sunlight like a halo. Her posture was rigid, her gaze fixed on a small patch of grass near her bare feet. Her expression was strange—vacant, almost trancelike, as if she were seeing something far beyond the physical world before her.
Toothy did not hesitate. The massive tiger bounded forward, his powerful legs propelling him across the clearing in three fluid leaps. He reared up, his front paws landing on Eve’s shoulders as his long, rough tongue swept across her face in an enthusiastic greeting.
Eve yelped, stumbling backward in surprise. Then she laughed—a bright, genuine sound that echoed through the clearing—as she wrapped her arms around the tiger’s thick neck.
“Toothy!” she exclaimed, burying her face in his fur. “You’re better! I’m so happy!”
The tiger rumbled with pleasure, nuzzling against her. Nutty, Squeaky, and Tiny arrived moments later, their small bodies skittering up Eve’s legs with practiced ease. They settled on her shoulders and arms, their tiny voices filling the air with excited chatters and squeaks. Eve laughed again, petting each of them in turn, though Toothy’s disappointed huff made it clear he felt neglected in favor of his smaller companions.
Then Eve’s gaze lifted, finding Adam standing at the edge of the clearing. His arms were crossed over his chest, his expression hard. He made no effort to conceal his annoyance, letting his disapproval radiate from him like heat from a forge. His crimson eyes bore into hers, unblinking and severe.
Eve’s smile faltered. Her hands stilled on the pets. She took in his posture, his furrowed brow, the tight line of his jaw. “What’s that look for, my love?” she asked, her voice carrying a note of uncertainty.
Adam huffed, a sharp exhalation through his nose. “Do you really have to ask?” He stepped forward, closing the distance between them. “You went out on your own. Without telling me. Without waking me. Even if the apes are gone, the jungle is still dangerous. You shouldn’t be so reckless, Eve.”
The fool woman had the audacity to look indignant. Her chin lifted, her hands moving to rest on her hips in a gesture of defiance. “So am I under your charge now? I can’t do anything without consulting you first?”
Adam took another step forward, looming over her. His shadow fell across her body, his height and bulk suddenly very apparent in the bright midday sun. His eyes, usually so soft when he looked at her, were hard as flint.
“Yes,” he said, his voice low and stern. “That’s exactly the case. Our lives are tied together now. Or did you forget that my life is forfeit if anything were to happen to you?”
The fight left Eve’s posture almost instantly. Her shoulders slumped, her gaze dropping to the ground between them. The defiance melted away, replaced by something softer—contrition, perhaps, or understanding.
“Look,” she said quietly. “I’m sorry, Adam. I just ... I had a strange inclination when I woke, and I had to follow it. I would’ve told you, but you’ve been pushing yourself so hard lately ... I didn’t want to wake you.”
Adam’s irritation began to cool, though it did not vanish entirely. He took a breath, steadying himself, forcing his temper back under control.
“What inclination?” he asked, his voice still edged with residual frustration. “What was so pressing that you felt the urge to leave the safety of my protection?”
Eve met his gaze. The vacancy was gone from her eyes now, replaced by something intense and searching. “I just ... I started thinking about what we talked about last night,” she said. “About how we might investigate where we came from. How we got here.”
She gestured to the patch of grass she had been staring at when they arrived. It was unremarkable—a small area of slightly lighter green, bordered by wildflowers. But there was something about it, something in the way Eve looked at it, that made Adam’s breath catch in his throat.
“You were right,” Eve continued. “I was able to remember where I first woke. It’s strange. I never felt the need to return here until we started talking about it.”
Adam looked down at the patch of grass, his mind racing. He felt a sudden, profound sense of dislocation—as if the ground beneath his feet had shifted, revealing something ancient and unknowable. The déjà vu he had experienced during his journey crystallized into certainty.
“You mean...” he breathed.
Eve nodded. “Yes. This is where I first came into consciousness. My first memories of being alive started right here.”
She took a deep breath, her blue eyes glistening with an emotion Adam could not quite name. A sad smile tugged at the corners of her lips.
“Although,” she added softly. “I don’t think I was truly living ... until we met a few moons later.”
Adam crouched low, his knees pressing into the soft earth as he examined the patch of grass Eve had indicated. At first glance, it appeared unremarkable—a roughly circular area perhaps six feet in diameter, the blades slightly lighter in hue than the surrounding vegetation. But as he lowered his palm to the soil, he felt it. Something was wrong.
He ran his hand over the grass, his enhanced senses reaching beyond the visible surface. The texture of the blades was subtly off—too uniform, too perfectly spaced. The soil beneath his fingertips lacked the rich, loamy density of the surrounding jungle earth. It was as if someone had concocted a mixture to approximate the appearance of fertile ground without truly understanding its composition. The best word he could find for it was artifice.
Adam pressed deeper, his fingers sinking into the dirt. The temperature was wrong, too—several degrees cooler than the earth should have been under the midday sun. There was no trace of the complex ecosystem of insects, roots, and decomposing matter that permeated every other square inch of the jungle. This ground was sterile. An imitation.
Eve crouched beside him, her blue eyes searching his face with desperate curiosity. “Well? Can you see anything?”
Adam kept his focus on the anomaly, his brow furrowing as he murmured, “Yes. There’s ... there’s something wrong with the ground here.”
He felt along the edges of the patch, noting how the normal jungle earth transitioned abruptly into the strange, artificial soil. It was like a seam where two incompatible realities had been stitched together. When his hand returned to the center of the circle, that same uneasy sensation washed over him—a profound sense of incorrectness that made his skin prickle.
“The earth and grass around this spot are normal,” Adam said, his voice low and troubled. “But here ... it’s different. This isn’t natural. It’s an imitation of the jungle that isn’t really the jungle.”
Eve leaned forward, her expression a complex mixture of fascination and dread. “So you feel it, too. When I found this spot, I felt like there was something wrong. That it was different from the rest of the jungle. That it didn’t belong.”
She straightened slowly, her gaze drifting upward to the canopy above. When she spoke again, her voice had a strange, distant quality—as if she were addressing something far beyond the physical clearing.
“Maybe I don’t belong here, either,” she said softly. “If this is the spot where I first came into being ... perhaps I’m just as artificial as this ground.”
Adam shook his head sharply, rising to his feet. The philosophical implications of their origins would have to wait. They had more pressing concerns.
“Eve. We don’t have time for this right now.”
Eve looked up at him, surprised. “But you were so dead-set on finding out our origins yesterday. You said it was important.”
Adam took hold of her shoulders, his grip firm but gentle. “That was before I realized something.” His crimson eyes bore into hers, intense and urgent. “Eve, we have to go back to the cave. To familiar territory where it will be easier to keep you safe. You must know that you’re...”
He froze. His senses—those enhanced perceptions that had kept them alive through countless dangers—were screaming. His hearing picked up the rapid approach of something massive, moving through the underbrush with terrifying speed. His nose twitched as a scent flooded his nostrils, unlike anything he had ever encountered. It was acrid and chemical, laced with a pheromone-heavy musk that burned his sinuses.
The creature was large. At least as large as he was. Perhaps larger. And it was making sounds he had never heard before—a rapid, staccato clicking, like bone striking bone in an ancient, alien rhythm.
Eve felt it too. Her head snapped toward the treeline, her body tensing. “What ... what in the world is that?” Her voice trembled. “It’s unlike any creature I’ve ever known.”
Her nose wrinkled in disgust as the scent reached her. “The smell. It’s familiar, but ... so different. There’s something unnatural about it. Something horrible.”
Adam moved without conscious thought, positioning himself between Eve and the direction of the approaching sound. His muscles coiled, his fists clenching at his sides. He had faced giant apes, raptors, a T-Rex, and a prehistoric shark. But never—never—had he felt such a pure, undiluted sense of danger. Not even the apes had radiated this kind of raw, predatory malice.
Toothy growled, the sound low and rumbling in his chest. The fur along his spine rose in a stiff ridge, his ears flattening against his skull. The smaller pets—Squeaky and Tiny, still perched on Eve’s shoulders—squeaked in terror, their tiny bodies trembling violently. Nutty, the russet squirrel, clung to Eve’s arm, his beady eyes wide with primal fear.
And then it came. The creature exploded through the treeline with the force of a battering ram. It was an ant—but such an ant as should never have existed in nature. Its body was a nightmare of chitin and muscle, easily six feet in length and standing nearly four feet tall at the thorax. Its exoskeleton was a glossy, obsidian black, gleaming with an oily sheen that seemed to absorb the sunlight rather than reflect it. Six legs carried its bulk forward with horrifying speed, each limb ending in a hooked claw that gouged the earth as it moved.
Its head was a massive, triangular wedge of armored carapace, dominated by a pair of mandibles that could have crushed a human skull like an eggshell. The jaws clicked together in that terrible, rhythmic staccato—a sound of pure, mindless hunger. Above the mandibles, two enormous compound eyes glittered like pools of crude oil, each one composed of thousands of tiny facets that caught and fractured the light into a thousand fragmentary images. Two long, segmented antennae whipped through the air, tasting the scents of prey and predator alike.
But most terrifying of all was the stinger. A massive, barbed protuberance extended from the creature’s abdomen, gleaming with a wet, viscous fluid that dripped onto the grass below. The venom hissed softly where it struck the earth, leaving small patches of scorched vegetation in its wake.
The ant barreled straight through a young ironwood tree in its path, snapping the trunk like a dry twig. Splinters of wood exploded outward, raining down on the clearing as the monstrosity charged.
Adam and Eve moved on instinct. The ant’s mandibles snapped at the space where Adam’s torso had been a fraction of a second earlier. The crushing pincers latched onto a nearby boulder the size of a man’s head—and crushed it instantly. Stone fragments sprayed outward like shrapnel, pinging off the surrounding trees.
Toothy was a blur of golden fur and flashing fangs. The sabertooth launched himself at the creature’s flank, his massive saber teeth sinking deep into the hard chitin of the ant’s thorax. Dark, ichorous fluid spurted from the wound, but the ant barely seemed to register the injury.
It let out a pained screech—a sound like tearing metal—and shook its body with terrifying strength. Toothy was thrown clear, his massive form tumbling through the air before landing on all fours twenty feet away. The tiger bounded to his feet immediately, shaking his head, regarding the insect monster with newfound wariness.
Adam’s mind went blank as he tried to quantify the horror before him. He had catalogued dozens of species in this jungle, memorized their behaviors, their strengths, their weaknesses. But this creature defied every framework he had constructed. It was not a product of natural evolution. It was something else entirely—something that should not exist.
Eve’s face had gone pale, her blue eyes wide with pure, primal terror. “What is it?” she breathed.
The ant’s mandibles clicked rhythmically as it surveyed the prey before it. Its antennae twitched, sweeping the air, sampling the scents of fear and sweat and blood. Then its massive compound eyes focused—not on Adam, not on Toothy.
They focused on the small, trembling forms of the pets. Nutty, Squeaky, and Tiny bolted for the safety of the treeline, their tiny legs pumping furiously. But they were not quick enough.
The ant lunged. Its speed was impossible for something so large. One moment it was ten feet away; the next, its mandibles were snapping at the fleeing rodents.
“NO!” Eve screamed.
She threw herself forward, her hands snatching Squeaky and Tiny from the ground mere seconds before the ant’s jaws snapped shut. The chipmunk and mouse squealed in her grip, their tiny hearts hammering against her palms.
But Nutty was not so fortunate. The squirrel had darted left while the others went right. The ant’s head swiveled, tracking him with horrifying precision. One snap of those massive mandibles, and Nutty was caught.
The squirrel let out one terrified squeak—a sound that would haunt Eve’s dreams for years to come—and then he was gone. The ant tilted its head back, its throat working in a grotesque swallowing motion. A small bulge traveled down its gullet and vanished.
Eve screamed—a raw, guttural sound of grief and horror. She scrambled backward, clutching Squeaky and Tiny to her chest, tears streaming down her face. The ant’s attention snapped to her, its compound eyes glittering with insatiable hunger. It began to advance.
Adam was there in an instant. He slammed into the ant’s flank, his shoulder connecting with the hard chitin. The creature staggered, but did not fall. Adam seized its mandibles, attempting to topple it, but even his incredible strength was taxed against the beast. The ant was heavier than it looked, its exoskeleton dense and unyielding.
As he grappled with the creature, Adam felt a searing pain lance through his hands. The ant’s mandibles were slick with venom, and where the fluid touched his skin, it burned like acid. Blisters began to form immediately, the flesh reddening and bubbling under the chemical assault.
Toothy charged back into the fray, his powerful jaws clamping down on one of the ant’s antennae. He yanked hard, tearing the sensory appendage partially free. The ant screeched again, thrashing wildly.
Eve deposited Squeaky and Tiny into the hollow of a nearby tree, her hands shaking. Tears blurred her vision, but beneath the grief, something else was building—a cold, burning rage. She grabbed a fallen branch from the ground, its end jagged and splintered.
“No, Eve!” Adam roared as he struggled to hold back the snapping mandibles. “Stay back! It’s too dangerous!”
But her fury was too great to heed his warning. With a war cry that sounded more beast than woman, Eve charged. She raised the branch high and drove it with all her strength into the ant’s left eye.
The compound structure shattered under the impact, dark ichor spraying outward. The branch drove deep into the soft tissue beneath, piercing whatever passed for a brain inside the creature’s armored head.
The ant squealed—a high, piercing shriek of agony. Its body convulsed violently, thrashing in every direction. Its stinger lashed out blindly, striking Eve in the shoulder.
The blow sent her sprawling, her body tumbling across the clearing. She came to rest against the trunk of a fallen tree, gasping, clutching her wounded shoulder. The flesh around the sting was already turning an angry red, the venom beginning its work.
Adam roared with all his rage. He ignored the burning agony of the venom on his hands. He ignored the way his skin blistered and peeled. He threw himself at the wounded ant with everything he had.
His fists smashed into the creature’s head, again and again. The tough carapace cracked under the relentless assault. Adam grabbed the edges of the broken exoskeleton and pulled, tearing it open to reveal the soft, pulsing tissue beneath.
He drove his fist into the exposed flesh, feeling it give way under his knuckles. Dark fluid gushed over his hands, mixing with the venom to create a new, even more excruciating burn. But he did not stop. He could not stop.
The ant’s body twitched and spasmed, its legs kicking weakly. Even after being reduced to little more than a shattered husk, it continued to move—its mandibles still clicking in that awful, mindless rhythm.
Toothy delivered the final blow. The sabertooth lunged at the creature’s exposed neck, his massive fangs sinking deep into the soft tissue. With a powerful twist of his head, he tore through whatever remained of the ant’s vital structures. The clicking stopped. The legs fell still.
It was over. Adam stood over the ruined carcass, his chest heaving, his hands covered in burns and ichor. The venom had done its damage—his skin was raw and weeping, the pain excruciating. But his enhanced physiology was already beginning its work, the tissue slowly knitting itself back together. He turned, his heart pounding, and raced to Eve’s side.
Adam crossed the distance between the ant’s shattered carcass and Eve’s prone form in three desperate strides. She lay crumpled against the trunk of the fallen tree, her body trembling, her eyes clenched tight against the agony radiating from her wounded shoulder. The stinger had struck true, piercing the soft flesh where her neck met her collarbone, and the wound was already an angry, inflamed mess.
Dark, discolored veins spread outward from the puncture site like the roots of some poisonous plant, creeping toward her throat and down her arm. The skin around the wound had turned a sickly purplish-black, swollen tight and glistening with a thin, viscous fluid that wept from the open gash. The flesh was hot to the touch, radiating a feverish heat that spoke of the venom’s rapid progress through her system.
Eve’s breathing was shallow and ragged, each inhale a small, pained gasp. Her face, usually so vibrant and full of life, had gone pale as milk, her lips taking on a faint bluish tinge.
“Eve,” Adam choked out, his voice cracking. “Oh, my Eve.”
Panic clawed at his chest, cold and suffocating. He had seen her injured before—battered by apes, bruised by their training, scraped and cut by the jungle’s countless hazards. But this was different. This was wrong. The venom was spreading with terrifying speed, and her body, for all its unnatural resilience, was losing the fight.
He pressed his fingers to her neck, searching for a pulse. It was there—rapid and thready, fluttering against his touch like the wings of a dying bird. Her skin was clammy, slick with a cold sweat that had broken out across her brow.
Think, he commanded himself. Think, damn you.
Adam forced his terror down, shoving it into the locked compartments of his mind where he kept all things that could not be allowed to interfere with survival. His intellect seized control, racing through options, discarding impossibilities, grasping at solutions.
The venom was the primary threat. He needed to slow its progress, give her body time to fight the infection. To do that, he needed to draw out as much of the poison as possible before it reached her heart or brain.
His gaze swept the clearing, cataloguing resources. There—the patch of strange, artificial grass where Eve had first awakened. But that offered nothing. Beyond it, the treeline. He needed specific plants, specific remedies. His memory, that cursed perfect recall, would serve him now. He remembered the shadow-leaf Eve had used to numb wounds, its properties acting as a mild paralytic. He needed the opposite—something to stimulate, to purge.
The river. They were miles from the river. Too far. But there, growing in the shade of a massive fern—a cluster of broad, waxy leaves with jagged edges. Bitter-root. He had seen Eve use it once on a minor cut. It drew out infection. It might draw out venom.
Adam moved with desperate efficiency. He ripped the bitter-root plants from the earth, clutching them in his blistered hands. The ant’s venom had burned his palms severely—the flesh was raw and weeping, the pain a constant, throbbing accompaniment to his thoughts. But his enhanced physiology was already fighting back, new tissue forming beneath the damaged skin, the healing process visible to the naked eye.
He returned to Eve’s side and knelt, crushing the bitter-root leaves between his palms until they formed a fibrous, green pulp. Dark sap oozed from the crushed plant matter, bitter and pungent.
“Eve,” he said, his voice steady despite the fear roaring in his chest. “I need you to stay still. This will hurt.”
