Lyrus gave the directions, and Aiden steered the skyship forward. Within minutes, they arrived at a towering mountain, its peak lost in the misty clouds. As they prepared to descend, the skyship abruptly halted in mid-air. An invisible force prevented them from moving further—a barrier, woven with ancient magic, blocking their path. No one could fly above the mountain.


    Aiden’s eyes narrowed. He considered blasting through the barrier but hesitated. Such an obvious solution rarely worked when dealing with ancient enchantments. There had to be another way.


    "There is a path through the mountain," Lyrus said, his voice calm but firm. "Between the rocks, a hidden cave leads to the other side."


    Trusting his guide, Aiden maneuvered the skyship to land at the mountain’s base. Without wasting time, they stepped onto the rocky terrain and followed Lyrus toward the concealed entrance. The cave was barely visible, nestled between jagged cliffs, but as they moved closer, its dark maw yawned before them, inviting yet foreboding.


    As they ventured deeper into the cave, the atmosphere shifted. The air grew heavy, charged with an overwhelming presence of mana. Alina, walking beside Aiden, tensed.


    "The energy here is... immense," she murmured, her voice laced with awe. Glowing mana-infused crystals jutted from the cavern walls, casting an eerie luminescence. The deeper they went, the stronger the sensation became. Aiden felt it too—not just the mana, but something else. A presence. A whisper that wasn’t quite a voice, resonating from within the depths of the cave.


    The same sound had lingered faintly in the air outside, but here, it was clearer—beckoning, familiar, as if calling to him directly. Aiden’s grip on his sword tightened. Now, he understood why Lyrus had chosen this path. The mystery of this place wasn’t just in its hidden passage; something ancient, something powerful, was waiting within.


    After what felt like an eternity, the cave finally opened up. A blinding light forced them to shield their eyes as they stepped out. When their vision adjusted, a massive structure loomed ahead.


    A castle.


    Black as the abyss, its towering walls stretched high into the sky. Vines and gnarled trees curled around its base, as if nature itself sought to consume it. Time had long forgotten this place—abandoned, untouched, and shrouded in secrecy.


    As they approached, Lyrus raised a hand. "Be careful. A guardian stands at the gate," he warned. "This is no ordinary creature. Even powerful spirits, even those at the Emperor level, have fallen before it."


    Moving cautiously, they followed Lyrus to a vantage point where they could observe the gate. There, standing motionless before the entrance, was the ghoul.


    Wrapped in tattered black cloth, its entire form was concealed. It had no legs, merely floating in place, an ominous figure against the darkened threshold. In its skeletal hands, it clutched a massive scythe-like weapon—its blade gleaming with an unnatural darkness.


    Aiden’s breath slowed. He studied the creature, watching for signs of movement, but the ghoul did nothing. It merely stood, as if waiting. Watching.


    Yet the air around it pulsed with a silent threat.


    Finally, Aiden exhaled, a glint of determination in his eyes. Without a word, he stepped forward.


    Lyrus warned him, "That weapon can kill you in a single strike. Even if you regenerate, you won’t last long."


    Alina placed a hand on Aiden’s arm, her expression serious. "This isn’t a battle you can afford to repeat. Escaping from that Astra palace again won’t be easy."


    Aiden only smiled at her before stepping forward. Alina wanted to stop him, but something in his demeanor told her she couldn’t.


    None of them knew that the ghoul standing before him was far stronger than his previous opponent—the leader of the unknown group. As he advanced toward the gate, two eerie lights flickered beneath the black hood. The ghoul had awakened.


    In an instant, it unsheathed its weapon and swung. The strike came so fast that Aiden barely had time to react. The dark blade cut through him—


    But nothing happened.


    Aiden glanced down at himself. Not a single scratch. The ghoul hesitated, its hollow gaze locked onto him. Then, with no pause, it slashed again. Once more, the blade passed through Aiden''s body as if he weren’t even there.


    The ghoul lifted a skeletal hand, black as the abyss, void of flesh or muscle. It reached forward, attempting to grasp him, yet its fingers phased through Aiden’s form like mist.


    Again and again, the ghoul attacked, its strikes growing more frantic. Aiden remained still. Each time, the attacks failed to touch him, as if the ghoul simply did not exist in his reality.


    Without looking back, Aiden walked straight into the castle. The ghoul did not follow.


    Inside, the castle was in ruins. Walls lay crumbled, their jagged edges telling the tale of a battle long past. Broken bricks and shattered debris littered the floor. Weapons—once wielded by warriors—now lay scattered, their shattered forms still radiating an ominous aura of power.

    Aiden ran his fingers along the hilt of a broken blade. Even in its ruined state, the weapon pulsed with energy. If reforged, it could rival even the legendary Forged Star Saber.


    He turned back. The ghoul remained outside, its presence lingering like a shadow at the gate. Wasting no time, he called for Alina, Lyrus, and Fame to join him.


    The four of them moved cautiously through the ruins, the air thick with the remnants of an ancient force. Strange weapons, their fractured edges still humming with residual power, lay strewn across the stone floor.


    Closing his eyes, Aiden listened. The wind whispered through the hollow halls. There was something deeper in the castle—something waiting. He led the group forward.


    Turning a corner, they stumbled upon an unexpected sight—a garden. It was unlike anything they had ever seen. The air was dense with energy, and the plants pulsed with raw, untamed power. The ground itself seemed alive.


    Drawn by curiosity, they stepped into the garden. Exotic plants thrived here, alongside rare spirit insects that shimmered in the dim light. But what truly caught their attention was what lay beneath their feet—Spirit Pebbles, Spirit Crystals, and Spirit Emeralds growing naturally in the soil.


    Alina gasped. "This… this is impossible. Spirit Emeralds can’t be cultivated. They appear randomly, without explanation. Yet… someone has managed to grow them."


    Spirit Emeralds were priceless treasures. No one could manufacture them, and no kingdom could buy them. Wars had been fought over a single fragment. If word got out, nations would burn to possess this garden.


    Lyrus, unable to contain his excitement, sought permission before swiftly gathering as many as he could. Meanwhile, Alina and Fame continued exploring the garden, enthralled by its mysteries.


    But Aiden’s mind was elsewhere. The castle’s true secret lay deeper within. If it had a core, and if he could claim it, then this place—this ruined kingdom—could be his.


    For the past few hours, he had mapped the castle in his mind. He had a rough idea of where the main hall—and its core—would be.


    As he walked through the desolate corridors, something called to him. An unseen force pulled him forward, urging him toward the heart of the castle. Taking a deep breath, he stepped through a massive doorway.


    And there it was.


    A colossal crystal, glowing with an ancient, pulsating energy, levitated in the center of the grand hall. Its size dwarfed anything he had ever seen. Most cores were the size of a fist. This one… was as large as he was.


    His breath caught. "The core of the castle…"


    Aiden had studied castle cores before. When a castle is built, it has no core. Only when someone claims it—binding their soul to it—does a core form. And this core was proof that the castle had once had a ruler.


    But who?


    And more importantly—what had happened to them?


    The castle was abandoned. The ruins spoke of war, yet no corpses remained. No one in their right mind would leave behind so much wealth, so many treasures, without a fight.


    Aiden clenched his fists. He wasn’t just standing in an ancient ruin. He was standing in the remnants of a fallen kingdom.


    A forgotten king had ruled this place.


    And Aiden was going to find out why he had disappeared.


    Aiden was about to touch the crystal when Alina''s urgent voice cut through the silence.


    "Don''t!" she warned. "The moment you touch the core, it will start absorbing your power and bind you as its ruler. But you don’t have the strength to claim it yet."


    He didn’t turn to face her. His fingers hovered inches above the glowing crystal.


    "How do you know?" he asked, his voice calm but firm. "I haven’t tried. Maybe I’ll make it?"


    There was an edge of defiance in his tone. Everything he had attempted so far had worked. He had begun to trust this feeling—that things would fall into place for him. That confidence had been carved into him through every challenge he''d faced.


    In the corner of his eye, he noticed Fame and Lyrus clutching sacks, their hands full of treasures looted from the garden. Spirit emeralds, rare herbs, and energy-infused stones—things kingdoms would wage wars for.


    Aiden made up his mind. If he didn’t try, he would regret it forever.


    Without a second thought, he placed his palm on the core. The moment his skin made contact, a violent force latched onto him.


    Power surged from within him—ripping, draining, devouring. It felt as though something deep inside was being yanked out. His vision blurred as his knees buckled under the overwhelming pull.


    He realized in an instant—he was going to die.


    Alina reacted immediately. She darted forward, grabbing him, trying to yank him away. But the force was relentless. The core had him in its grasp.


    She swung her sword at the link—nothing. She cast spells—useless. The connection between Aiden and the core was unbreakable.


    Aiden could barely think. His body was weak, numb, slipping into unconsciousness. He felt his very essence being consumed by the castle itself.


    The pain was unbearable. The suction force was so overwhelming that it felt as if his very muscles and organs were being crushed, wrung dry of every ounce of power. His body no longer obeyed him—paralyzed, trembling, and drained beyond its limits.


    His vision blurred. His world twisted and distorted, as though reality itself was unraveling. A creeping numbness spread through his limbs, yet the agony did not fade. Instead, it deepened, burrowing into his bones like a curse.


    Was he even still alive? Or had the core already consumed him?


    Half-conscious, his thoughts wavered, slipping between clarity and delirium. Regret clawed at him. He should never have touched it. He should have listened. But now, it was too late. The core was relentless, devouring him piece by piece, and there was nothing he could do to stop it.


    But in that moment of despair, something else happened.


    A new presence.


    A force unlike anything he had ever encountered.


    The air grew heavy, charged with something ancient, something deadly. Footsteps echoed through the hall—slow, deliberate. Each step sent a tremor through the room.


    Even in his half-conscious state, Aiden could feel it. This power dwarfed everything—the garden, the castle, even the core itself. It wasn’t just powerful. It was overwhelming.


    And then—


    [The Wards of the World cannot be claimed or given.]


    A system notification. A rule of existence itself.


    The link severed. Aiden gasped as his body collapsed onto the cold stone floor, trembling, his strength completely drained.


    Darkness swallowed him as his consciousness faded.


    The footsteps grew louder.


    Alina wasted no time. She threw open the doors and, without hesitation, teleported the group out of the castle.


    A moment later, a lone figure entered the core chamber. He surveyed the space, his gaze settling on the crystal before a slow smile curved his lips.


    "Finally," he murmured. "Someone strong enough to enter this castle."


    His eyes gleamed with a mix of amusement and anticipation.


    "At last," he whispered. "The time has come for me to be free."


    A mysterious man. A ruined castle. And a fate yet to unfold.
