Tarnis's powerful Essence surged behind them like a raging storm, shaking the cavern walls with its force. Kael guided Lena swiftly through winding tunnels, his senses razor-sharp, Essence flowing instinctively to envelop them both in a cloak of shadows. Every breath, every heartbeat felt amplified in the tension-filled silence.
Kael knew Tarnis was stronger—too powerful for him to fight directly. His only hope was escape, to use the shadows he had now mastered, slipping away unseen.
But Tarnis wasn't easy to shake.
The tunnels twisted deeper, air growing colder, stale with age. Kael sensed ancient formations embedded in the walls, protective arrays pulsating faintly, remnants of the forgotten civilization that built this place. His Essence resonated softly with them, like whispers from old memories.
Behind them, Tarnis's voice echoed ominously through the passages. "Running only delays the inevitable, Kael. Face your end with dignity."
Kael didn't respond. Instead, he channeled Essence more fiercely, his shadow cloak thickening, blending seamlessly into the darkness. Lena's breathing was shallow but controlled; she trusted him completely now.
Suddenly, the path split again, branching into three separate tunnels. Kael paused momentarily, sensing carefully. The left tunnel felt colder, dense with ancient Essence. The right pulsed faintly with danger. The middle seemed neutral, silent, empty.
Instinct guided him toward the colder path. The deeper they moved, the stronger the strange energy became, wrapping around them like an icy blanket.
Kael stopped abruptly. Ahead, the tunnel ended at a large stone door, ancient runes glowing faintly across its surface. Lena stared at it, uncertain.
"What is it?" she whispered.
Kael stepped closer, examining the runes carefully. They pulsed rhythmically, reacting to his presence. He recognized them immediately—an ancient sealing array, designed to hide powerful artifacts or dangerous beings.
"I think it's a sealed chamber," Kael explained quietly. "Whatever's inside could help us—or destroy us."
Behind them, Tarnis's footsteps grew louder, closer. Time was short.
Kael placed his hand against the door, Essence flowing instinctively into the array. Immediately, the runes flared brilliantly, responding eagerly to his shadow-infused Essence.
The massive stone door shuddered and began to slowly slide open, dust and debris showering down. Cold, ancient air spilled out, heavy with power and secrets.
"Go," Kael urged Lena, gently pushing her through the widening gap.
They slipped inside quickly, and the stone door slid shut again, sealing them within absolute darkness.
Kael summoned Essence into his palm, creating a faint sphere of light. Its glow barely illuminated the room, revealing towering shelves carved directly into stone walls, lined with ancient scrolls, artifacts, and sealed containers. At the chamber's center stood a pedestal holding a small black orb, pulsing gently with dark Essence.
Kael approached cautiously, sensing powerful, dangerous energy emanating from it. Lena moved closely behind, eyes wide with awe and caution.
"What is this place?" Lena murmured softly.
"An ancient repository," Kael replied quietly, examining the orb carefully. "Built by cultivators who walked paths now forgotten."
Before he could investigate further, the stone door shuddered violently behind them. Tarnis had found their hiding spot, his immense Essence battering the protective seal relentlessly.
Kael's pulse quickened sharply. The barrier wouldn't hold long—Tarnis was simply too powerful.
He turned toward Lena urgently. "We need something here, something powerful enough to fight or escape."
Lena quickly scanned the shelves, searching desperately. Kael's eyes remained fixed on the black orb, instincts whispering warnings and promises simultaneously. He knew it was dangerous, yet it resonated powerfully with the shadow Essence he now controlled.
As Tarnis's strikes intensified outside, Kael made a decision. Carefully, he reached toward the orb, Essence flowing from his fingertips to gently envelop it.
Instantly, the orb reacted violently, shadows erupting outward, swirling chaotically around Kael. Lena shouted, fear evident in her voice, but Kael held steady, forcing control over the wild energies.
Slowly, the shadows stabilized, swirling obediently around him, merging seamlessly with his existing shadow cloak. The orb disintegrated completely, leaving behind a small, intricate black mark on Kael's palm—another binding, another pact forged in shadows.
Kael felt power surge within him, deeper, darker, more profound than ever before. His shadow Essence now felt boundless, fluid, responsive to every thought.
At that moment, the stone door shattered violently, debris scattering everywhere. Tarnis stepped through calmly, Essence raging fiercely around him, eyes narrowed dangerously beneath his mask.
"Found you," Tarnis growled softly.
Kael stood protectively before Lena, his Essence surging with newfound strength. Tarnis paused slightly, noticing the change immediately.
"You've embraced something dark," Tarnis noted calmly. "But darkness will not save you."
Without another word, Tarnis raised a hand, crimson flames surging forward violently. Kael reacted instantly, his shadow Essence forming a barrier that absorbed the flames effortlessly, darkness swallowing the light.
Tarnis's eyes widened slightly, surprise evident despite his controlled demeanor.
Kael smiled faintly, confidence renewed. "Maybe darkness won't save me—but it might destroy you."
With incredible speed, Kael launched forward, shadows swirling violently around him, concealing his movements perfectly. He appeared instantly beside Tarnis, blade slicing precisely toward his exposed side.
Tarnis deflected the strike swiftly, retaliating with furious punches encased in fiery Essence. Yet Kael's movements were now impossibly swift, flickering through shadows, vanishing and reappearing unpredictably.
Their clash shook the chamber violently, artifacts and scrolls scattering wildly. Lena retreated quickly, hiding behind a massive stone shelf, watching fearfully yet hopeful.
Kael moved gracefully, seamlessly merging Void Step and Essence Split Form techniques with his newfound shadow mastery. Multiple afterimages attacked simultaneously, forcing Tarnis into constant defense.
Yet Tarnis was still overwhelmingly powerful. His Essence surged violently, flames burning hotter with each passing moment. His fists and palms became weapons, each strike erupting with destructive power.
Kael struggled to maintain the pressure, Essence rapidly draining. He knew he couldn't win directly, but he had one advantage now: unpredictability.
He suddenly merged fully into shadows, vanishing entirely. Tarnis paused cautiously, scanning the chamber carefully.
"Is this your new tactic? Hiding like a coward?" Tarnis mocked coldly.
Kael didn't respond, moving silently through shadows, positioning carefully. He appeared suddenly beside Lena, whispering urgently. "Follow closely. Trust me."
Lena nodded quickly, gripping his hand tightly. Shadows enveloped them instantly, concealing their presence completely.
Tarnis sensed the shift, unleashing furious Essence attacks wildly through the room. Fire and debris erupted everywhere, yet Kael guided Lena precisely, slipping between attacks, maneuvering carefully toward the shattered doorway.
They emerged silently into the tunnels again, shadows guiding their movements flawlessly. Tarnis's frustrated roar echoed behind them, Essence surging angrily, chasing relentlessly.
Kael raced swiftly through winding paths, shadows responding effortlessly to his intentions. Lena stayed close, trusting his every step. The power of shadows felt limitless now, each moment enhancing his understanding.
Finally, the tunnel widened abruptly into another massive cavern. At its center was a glowing teleportation array—ancient, but still functional. Kael paused, quickly examining it.
"We can escape through this," he whispered urgently. "It'll transport us away from Tarnis—but I'm not sure where."
Lena nodded immediately. "Anywhere is better than here."
Kael activated the array quickly, Essence surging into the formation. It hummed powerfully, glowing brighter with each second. Yet Tarnis's presence closed rapidly behind them.
Just as the array reached full activation, Tarnis burst into the cavern, eyes blazing furiously.
"You will not escape!" Tarnis roared, unleashing a terrifying wave of Essence, flames racing toward them rapidly.
Kael stood protectively before Lena, Essence shielding them fiercely. The teleportation array surged with power, enveloping them both instantly.
The flames reached them at the exact moment they vanished, pain erupting briefly before the cavern disappeared completely.
Kael felt himself pulled violently through space, consciousness flickering from the strain. He had no idea where they would emerge—but anywhere was safer than facing Tarnis again.
Yet, even as they traveled, a cold realization settled deeply within him: Tarnis knew about his shadow powers now. Kael's secrets had been exposed.
The next confrontation would be far more dangerous—and far deadlier.
