According to Allen’s map, the final and most severe infestation of nightmare vines was located at an ancient lake deep in the heart of the forest. This place, known in old texts as “Moonmirror Lake,” was once revered as a sacred site of powerful magic—a ceremonial ground for the forest elves. But since the Great Cataclysm a century ago, the elves had vanished, and Moonmirror Lake faded from living memory.

  By dusk, the golden light of the setting sun filtered through the canopy, casting a warm glow on the forest path. At long last, the two arrived at the lake’s edge—but when they stepped through the last curtain of trees and laid eyes upon the scene before them, they froze in stunned silence.

  The lake that was once crystal clear now shimmered with an eerie, deep violet hue. Withered petals and leaves floated atop the surface, releasing a thick, pungent scent of decay. Even more disturbing, the shoreline was completely overtaken by nightmare vines—twisted purple-black growths that wrapped around one another like a massive, suffocating web. The magical pressure in the air was suffocating, so intense that even Qian, still new to the arcane arts, could feel it pressing down on her chest.

  “The concentration of magic here... it’s completely unnatural,” she murmured, clutching her staff so tightly her knuckles turned white. “Stronger than anywhere we’ve been.”

  Sern stepped forward cautiously, his eyes scanning the lake and the terrain around it. “We have to proceed carefully. This might be more than just a vine-clearing mission.”

  They decided to test the waters with a ranged spell. Qian took a deep breath, planted her feet, and gripped her staff with both hands. Her eyes, usually lively, now held a solemn focus.

  This wasn't her first time casting fourth-tier magic—but it was the first time she had used it in real combat.

  She began chanting, her voice steady and rhythmic, each syllable vibrating through the air like flickers of fire.

  “Flame Spirit: Pale Blaze!”

  At the final word, the crystal at her staff’s tip burst into a searing red light, tearing through the twilight sky. A massive flame pillar roared upward, compressing rapidly as it climbed. The fire shifted in color, turning from crimson to a chilling blend of pale blue and white, its temperature spiking until even the air seemed to burn. Then it plunged like a meteor into the densest patch of vines along the lakeshore.

  The moment the flames struck, the entire lake quaked—as if a slumbering beast had been rudely awakened. Violent whirlpools churned the waters, and the nightmare vines didn’t burn as expected. Instead, they twisted wildly, writhing as if in response to some summons, uprooting themselves from the lakeshore and wriggling toward the center of the lake.

  Then, something immense began to rise from the depths.

  A colossal humanoid figure, formed from tangled vines and churning water, emerged slowly from the heart of the lake. It stood three stories tall, its entire body wrapped in scale-like tendrils that pulsed with malevolent life. At the center of its head—a mass of tightly bound vines—burned two cold blue flames that resembled eyes, locked onto Sern and Qian with chilling intensity.

  “My gods… what is that?” Qian gasped, instinctively stepping back.

  The creature let out a guttural roar, a monstrous blend of crashing water and the rasp of shifting vines. It raised a massive arm—a fusion of water and tendril—and brought it crashing down toward them.

  Sern’s eyes flashed. He grabbed Qian and rolled sideways, narrowly avoiding the impact. The earth quaked beneath the blow, spraying dirt and splintering stone. Fissures opened across the ground, mud and water bubbling from below.

  “This thing…” Sern muttered through clenched teeth, glaring at the creature’s unscorched vines, “it’s regenerating. The vines are pulling back toward the core—it’s healing itself.”

  His tone grew darker. The creature wasn’t natural—it was a fusion of twisted magic and something else, an engineered abomination.

  “Its defenses are too strong!” Sern shouted as he vaulted away from another sweeping blow. The vine-and-water arm tore through the battlefield like a scythe, crushing trees and shattering boulders. “Regular attacks don’t even scratch it!”

  Stolen content warning: this content belongs on Royal Road. Report any occurrences.

  He panted, now soaked and dirtied, his flame-infused sword barely searing the surface. Even where fire had caught, the vines shed their scorched layers, regenerating in seconds.

  “I’ll draw its attention!” Qian called out, sweeping her staff and launching a barrage of elemental spells—wind and fire in rapid succession. A whirlwind kicked up debris, blinding the creature for a moment. She followed with a fire burst, trying to disrupt its rhythm.

  But the monster did not falter. It twisted within the flames, shedding burnt tendrils and growing new ones. It struck again—its massive hand covering the span of the battlefield. Qian wasn’t fast enough. The impact sent her flying into a fallen tree, where she landed with a stifled cry.

  “Qian!” Sern roared, driving back the monster momentarily and rushing to her side. He helped her to her feet. Blood traced the corner of her mouth, her face pale, hair tangled with sweat and ash.

  “I’m fine…” she whispered, forcing herself upright, but her gaze remained locked on the towering creature. It had grown faster, its strikes more calculated—its movements suggested awareness, intent.

  “It’s no use…” she breathed. “We can’t break its shell. It just keeps healing.”

  Sern said nothing, his eyes narrowing as he studied the creature. Then he noticed it—buried within the head of vines, nestled deep in its core, were two burning blue flames.

  “Qian,” he said quietly, but firmly. “Its head—those blue lights. You see them?”

  She followed his gaze. “They look like... eyes.”

  Her expression hardened. “That must be its core.”

  He nodded. They didn’t need to say more. Qian would distract the creature. Sern would strike.

  “Frost Spirit: Chain of Ice!”

  With a wave of her staff, Qian summoned crystalline chains from the air, binding the monster’s legs in a sudden frost. The vines shrieked and writhed, but their movements slowed as the freezing spell took hold.

  Sern seized the moment. “Wind Veil: Phantom Step!” Air spiraled around his feet, lifting him with sudden speed. He dashed to the lake’s edge, sprinted up a thick trunk, and leapt—sword raised high—toward the monster’s head.

  His blade cut through the air, aimed straight for the burning core. But just as it neared the mark, a powerful shockwave burst from the vine-mass, slamming into him like an invisible wall. He cried out, tumbling midair before crashing hard into the ground.

  Pain lanced through his arm—he could barely hold his sword. He looked up just in time to see the creature regenerating once more, the vines rewrapping the core without a trace of damage.

  The monster retaliated, launching a wave of vine-shredded water. The blast struck Sern squarely, hurling him backward.

  “Sern!” Qian shouted, casting wind magic to soften his landing. A gentle updraft caught him, reducing the impact.

  Sern groaned, pulling himself upright, sword shaking in his hand. The creature had broken free of its bindings and now stood undeterred.

  “We need stronger fire,” he rasped. “Normal magic can’t pierce its core.”

  Then he remembered—the special powder Allen had given them that morning.

  “The powder!” he shouted. “Mix it with the firestone essence!”

  Qian understood instantly. She poured the powder into one of the vials and shook it. The liquid flared from deep red to brilliant gold, the vial radiating searing heat.

  “Pour it on your sword!” she yelled, even as she began chanting again.

  Sern doused his blade. The gold fire enveloped it, igniting the runes along its surface. The sword blazed with golden light, infused with ancient magic and concentrated flame.

  Qian’s chant crescendoed, her staff trembling as fire swirled into a vortex of rising heat. The air warped around her, and she released the spell:

  “Flame Spirit: Purifying Storm!”

  A cyclone of golden fire erupted around her, surging outward. She hurled a second vial into the vortex. The flames transformed—red turned to blinding gold as a roaring inferno stormed toward the monster, engulfing it completely.

  The creature screamed—a sound of forests dying and rivers boiling. The vines burned black and fell away. The blue flames at its core flickered and thrashed. The water that once bound it collapsed, its form beginning to unravel.

  Sern charged through the fire, guided by Qian’s magic. The flames parted before him. He raised his blazing sword.

  “Wind Veil: Radiant Cleave!”

  The golden blade pierced the heart of the blue fire. A blinding light exploded across the lake, igniting the sky. The monster wailed in agony. Its colossal body collapsed—vines withered, water fell like rain.

  From the core, a mass of blue energy burst forth, swirling into a great sphere above the lake. It trembled violently—then shattered into a thousand glowing fragments that scattered into the night wind.

  Moonmirror Lake fell still.

  The waters cleared, the nightmare vines lay lifeless on the ground. The pressure in the air was gone, as if the chaos had never occurred.

  Sern and Qian collapsed at the lakeshore, covered in ash and dirt, gasping for breath.

  Sern looked at the lake and gave a slight nod. His voice was calm but heavy. “It’s over… for now. But that blue energy—what was it? Why could it control the vines?”

  “And where did it come from?” Qian asked softly, leaning against a stone. “That wasn’t natural magic…”

  The forest dimmed as twilight faded. Only the last embers of sunset remained. The birds had gone quiet. The breeze carried the scent of scorched vines and damp soil.

  “Let’s go. It’s getting dark,” Sern said, rising slowly and offering her a hand. “We’ll check the lake again tomorrow. Right now, we need to get back to Allen—and tell him everything.”

  Qian grasped his hand and pulled herself up. They adjusted their gear and began their slow walk back down the forest path.

  The Trial Forest looked peaceful again.

  But deep down, they both knew this battle had only scratched the surface of a much greater mystery.
