Isaac was a boy adrift in the vast ocean of his own potential, searching for a self he hadn't yet met. Having just emerged from the gauntlet of high school, he had sat for the national exams and, to the surprise of absolutely no one, achieved a perfect score. The world was spread before him like an unrolled map; he could choose any university, any prestigious career. There were no limits to his future. Yet, despite the infinite horizons, he felt profoundly lost.
As a reward for his performance, he asked his parents for a trip to the rural heart of Mato Grosso do Sul. With a week remaining before university applications opened, he promised them he would return with a decision.
They didn't mind his indecision. They never really minded anything he did. No matter what path he chose, he knew he would never receive a "well done"—at least, not from them.
"It's beautiful here," he mused aloud, his eyes fixed on a majestic waterfall that tore through the emerald curtain of the rainforest.
"Beautiful, yes. But don't you go thinking about taking a dip," the expedition guide warned, watching him with a sidelong glance. "Beneath that drop lies a labyrinth of caves. There's a low-pressure current that acts like a vacuum, dragging swimmers under. Anyone brave—or stupid—enough to try has never come back."
"What a terrible way to go," a tourist remarked. A murmur of grim agreement rippled through the group. Isaac nodded along, the words chilling the air.
Despite the dark legend, the group decided to camp nearby to wake up to the view. They built a fire, shared stories, and laughed late into the night. But Isaac was a ghost at his own feast; his body sat by the flames, but his mind was leagues away.
My trip is almost over, and I still don't know, he thought, staring into the embers. I thought if I studied hard enough, I'd find something I loved.
He had come close to that feeling when teaching himself new languages. At seventeen, Isaac was already fluent in fourteen—a natural, effortless polyglot. But he couldn't see a career in it; to him, it was just a hobby. The sciences held no charm either. He would likely end up in some random degree, chasing a piece of paper he didn't want.
Am I going to be like my father? Leaving the house every morning with a hollow chest because I hate what I do?
He stepped away from the circle of light to relieve himself, seeking a moment of true silence. Once the laughter of the group had faded into a distant echo, he found a quiet spot. He finished with a resigned smile, coming to a cold conclusion: passion was a myth. He would choose the career with the highest paycheck. If he was destined to be unhappy, he might as well be rich.
Before he could turn back, a rustle in the brush turned his blood to ice.
Two glowing eyes, crimson and predatory, stared back from the darkness. Isaac was no fool. He knew exactly what he was looking at: a jaguar. The apex predator of the Americas, possessing the strongest bite in the world.
With a frozen calm, he raised his arms to appear larger—a desperate, classic tactic. He backed away inch by inch, never breaking eye contact, never turning his back. When he had put ten meters between himself and the beast, and the jaguar remained a statue in the shadows, he made a choice. He turned and ran.
Branches whipped his face like lashes as he bolted toward the thunder of the waterfall, certain he was heading back to camp. It was a fatal miscalculation. The forest floor vanished into slick, wet rock. Before he could find his footing, he was airborne, plunging into the frigid lake below. Driven by the primal thrill of the hunt, the jaguar leapt after him.
With no other choice, Isaac swam for the center of the lake. That was when he felt it—the pull. He fought desperately against the invisible hand of the current, but it was like fighting the earth itself.
In an instant, Isaac and the beast were swallowed by a throat of stone, dragged down into a swirling vortex of darkness and suffocation.
Isaac awoke to the metallic tang of blood in his mouth and the rhythmic, incessant drip-drip-drip of water hitting stone. When his eyes flickered open, he found the darkness was not absolute; the cavern walls exhaled a faint, bioluminescent blue glow, revealing massive stalactites hanging from the ceiling like the fangs of a stone giant. The air was heavy, thick with the scent of mildew and damp earth. Everything felt blurred, like the lingering fragments of a nightmare that refuses to dissolve upon waking.
"Right... I was hunted by a jaguar, fell into a whirlpool, and then..." He fumbled blindly across the cold ground, trying to orient himself. "How is this even possible? There's no running water here. How did I end up in this place?"
Determined to find an exit, Isaac began to explore the grotto. Every fiber of his being protested, sending waves of sharp pain through his limbs.
"Damn it, it feels like I'm three times heavier," he cursed, feeling an oppressive gravity crushing his shoulders. The pitch-black void beyond the blue glow was dense, concealing the treacherous terrain.
He moved slowly, leaning against the damp walls for support. After five minutes, a strange sound made him freeze: a wet, rhythmic gnashing. Creeping forward with extreme caution, he approached an opening in the rock. What he saw made his heart lurch into his throat. Beneath the pale blue light, a monstrous creature was gorging itself on the remains of the jaguar. It wasn't an animal that should exist; it possessed the build of a wolf, but with the raw muscle mass and sheer scale of a grizzly bear.
Terrified, Isaac retreated step by step until he felt he had reached a safe distance, then bolted in the opposite direction. His thoughts spun wildly: Is this a nightmare? Or did I die and end up in Hell? He decided not to dwell on the theories. His only priority was escaping before he became the next course.
The cavern floor was a labyrinth of jagged rocks and fissures. Isaac stumbled and fell repeatedly, his skin becoming a map of abrasions, until he spotted a faint white light emanating from a hole in the wall. It looked like sunlight—or so he desperately hoped. He clawed at the opening frantically, prying away stones and earth until he could squeeze his body through to the other side.
It wasn't an exit. The jagged cavern walls gave way to smooth, carved stone. Everywhere he looked—on the floor, against the walls—were stone coffins. To his despair, the light he had seen came from a narrow crack in the ceiling, at least fifteen meters high and utterly inaccessible.
"Great. At least I won't lack a proper burial."
The walls of the chamber were hard and far too steep; scaling them would require a strength his exhausted body simply didn't possess. The silence was suddenly shattered by a howl that made the very floor vibrate, followed by the heavy, thundering gallop of something approaching fast.
"The thing is coming! I need a plan, now!"
Desperate for any form of defense, he noticed one of the sarcophagi. It was partially ajar and, unlike the others, was encrusted with jewels and strange metals. Someone of great importance had been laid to rest here. He shoved the lid aside, discovering a spear of tarnished silver. Its ancient owner still gripped it with skeletal fingers—nothing remained but brittle bone and the tattered scraps of antique armor.
"Did I just stumble into the ruins of some ancient crypt? If I get out of this, I'll be famous, but still..." He felt a flicker of guilt at the thought of being a grave robber.
However, when he heard the monstrous wolf sniffing at the small opening he had left in the wall, Isaac tossed his moral quandaries aside. He offered a silent prayer of thanks to whoever the corpse had been and seized the spear.
Seconds later, the great wolf burst through the entrance, shattering the rock wall with its brute force. Up close, the beast was a vision of pure terror: fur as black as smoke, eyes like burning embers, and claws that looked forged from dark metal. A glowing red stone was embedded in its forehead. It's a demon, terror flooded Isaac's mind. There's no other way to describe it. How is this possible?
He backed into the far corner of the crypt and leveled the spear. He braced the butt of the weapon where the floor met the wall, using the very structure of the room to anchor the impact at a forty-five-degree angle.
Driven by hunger, the monster lunged. Isaac, despite the shearing terror in his chest, kept his hands steady. The beast, blinded by primal fury, didn't seem to notice the sharpened tip of the spear as it hurtled forward at full speed.
The impact felt like a car crash. The vibration shuddered through Isaac's arms. He had feared the weapon might be blunt or brittle with age, but the blade sank into the creature's throat like a hot knife through butter.
The wolf recoiled with a high-pitched yelp, but the damage was done; dark blood sprayed from its arteries. In a final, desperate burst of life, the beast tried to snap at him once more, but Isaac was ready. He redirected the spear, impaling the creature again—this time straight through the chest. After ten agonizing seconds, the giant slumped, its heavy breathing fading into nothingness.
Driven by a surge of pure adrenaline and trauma, Isaac let out a raw scream, raining blow after blow upon the carcass to ensure the nightmare wouldn't stand back up. When silence finally returned to the crypt, exhaustion claimed him. His knees buckled, and he collapsed onto the cold stone floor, unconscious.
