The thin air of the mountains tightened Castian and Shen's chests as they slowly made their way toward the cave. The silence of the night, disturbed only by the sound of their boots crushing stones, seemed to conspire against them. The dark sky, heavy with thick clouds, concealed any sign of hope or light. That place emanated something malevolent, and Castian could feel the weight of that energy seeping into his bones.
The cave, a sinister opening between the rocks carved by time, seemed to breathe. It was a slow, disturbing breath, as if something immense and dormant was waiting inside, lurking. The chill that crept up Castian's spine was not just the cold of the mountains but the foreboding of what awaited them beyond the entrance.
"This is it," murmured Shen, his voice almost swallowed by the howling wind around them. There was a seriousness, a shadow of regret in his words that Castian could not ignore.
"The seal... and the entity imprisoned?" Castian asked, trying to keep his voice steady. But the nervousness was present, manifesting in the way he gripped his sword tighter than necessary.
Shen looked at him for a long moment before answering, as if weighing each word he was about to say.
"Yes," he finally said, his voice low, laden with ancient weight. "The seal is weakening, faster than we expected. And if we don't reinforce it... well, everything we've faced so far will seem like child's play."
The warning hung in the air like a veiled threat, amplifying the already suffocating tension. Castian swallowed hard and forced himself to take the first step into the cave.
The air changed as soon as they crossed the threshold. It wasn't just the humidity or the musty smell that seemed to cling to their clothes, but something deeper, more disturbing. The cave itself seemed alive. The walls, covered in damp moss, appeared to pulse slightly, a faint, intermittent glow emanating from the depths. The silence within was absolute, broken only by the sound of their footsteps and their heavy breathing.
"This place..." murmured Castian, trying to ignore the uncomfortable sensation of being watched. "Everything here feels wrong."
Shen raised the lantern he carried, revealing the uneven path ahead. Sharp rocks, bizarre formations of stalactites and stalagmites seemed to create distorted figures in the shadows. Everything within the cave contributed to the feeling of crossing the threshold into a world that should not exist.
"Stay alert," Shen warned, his voice heavy with concern. "This place is alive... and it does not like our presence."
Shen's words echoed through the cave, strangely reverberating against the walls. Castian looked at him, feeling a chill that had nothing to do with the cave's cold. The distrust in his chest grew with every step.
As they advanced, the cave's corridors became narrower, more oppressive. Castian tightened his grip on the sword more than he would care to admit, his eyes constantly scanning the shadows around. The muffled sound of something heavy being dragged across the ground, followed by a deep, threatening grunt, broke the silence.
"They're coming," murmured Shen, as if he had already anticipated the inevitable. He kept his gaze fixed ahead, without any hesitation.
Suddenly, from the shadows of the walls, more sentinels emerged. Grotesque creatures, even larger and more imposing than those they had faced before, emerged like hungry predators. Their eyes gleamed with uncontrollable hatred, and their sharp claws scraped against the ground, creating a metallic, disturbing sound.
"Prepare yourself!" shouted Shen, drawing his blade and taking a defensive stance.
Without hesitation, Castian charged forward. The first creature, with a guttural roar, lunged at him. Castian dodged to the side, spinning his blade with deadly precision. The sword cut through the creature's flank, which let out an agonizing scream, but before he could retreat, another sentinel attacked him from the side. The impact of its claws against his blade was so strong that he felt his arms tremble.
"These things won't stop!" Castian shouted as he struggled to maintain his balance and counterattack. Shen was at his side, cutting and dodging with surprising agility for his age. But the number of creatures was overwhelming, and they seemed endless.
Once again, one of the sentinels advanced, but before it could sink its claws into Castian, he slid beneath it, spinning his sword and plunging it deep into the creature's belly. Dark, thick blood gushed out, staining the stones beneath his feet, and the monster fell with a muffled scream.
Breathless, feeling his muscles burning with fatigue, Castian knew they couldn't let their guard down. The remaining sentinels continued to advance, relentless, driven by a blind determination to protect whatever was sealed within the cave.
"Watch out!" shouted Shen as another creature descended with its claws aimed at Castian. He ducked just in time, spinning around and striking the monster's legs. With a quick movement, Shen finished the attack, severing the creature's head.
Finally, as the last sentinel fell, a deadly silence descended upon the cave. The only sound was the heavy breathing of the two warriors, exhausted from the battle. Castian wiped the sweat from his forehead and looked at Shen.
"They won't stop, will they?" he asked, knowing the answer even before hearing it.
"No," Shen said, his voice tense. "They are here to protect the seal. And as long as it remains weakened, more of them will come."
Castian nodded, still catching his breath, but before he could react, something unexpected happened.
A whisper. Soft, faint, almost inaudible, drifted through the air around Castian.
"Castian..."
He froze. The sound was unmistakable, and for a moment, terror overtook him. He looked around, eyes wide, trying to understand where that voice was coming from.
"What was that?" Shen asked, noticing Castian's tense expression.
"Nothing," he murmured, shaking his head. "Am I hallucinating?" He tried to push the thought away, but the discomfort lingered.
They continued to advance, but then the whisper returned, this time clearer, closer.
"Castian..."
This time, he stopped in his tracks, his entire body tense, his eyes fixated on a vacant spot in front of him.
"Did you hear that?" his voice was barely a whisper, filled with disbelief.
Shen halted and looked at Castian, his eyes narrowed with concern.
"What did you hear?" Shen asked, clearly cautious.
Castian looked directly at him, his mind spinning with confusion. He didn't know if he should tell the truth, but something inside him compelled him to speak.
"Someone... someone is calling me. I heard my name. Twice."
The silence that followed was oppressive. Shen furrowed his brow, his face hardening. His expression shifted from concern to something much darker.
"This is bad, very bad," he murmured, almost inaudibly, but Castian heard enough to feel a chill run down his spine.
"Why?" Castian asked, feeling fear root itself deeper in his chest.
Shen hesitated for a moment, his gaze locked onto Castian's eyes, as if evaluating something deeply. When he finally spoke, his voice was heavy with regret.
"I made a mistake bringing you here. A grave mistake."
