Roared. The beast lunged, a whirlwind of claw and scale. Its crimson eyes burned with a primal rage, its jaw unhinged, revealing rows of needle-sharp teeth slick with venom. Kaelen pressed himself against the cold, damp stone, his heart hammering against his ribs. The uncontrolled mana burst had bought him seconds, nothing more. Now, raw terror threatened to paralyze him. Fangs snapped, missing his head by inches. A claw ripped a gouge in the stone beside him, sending a spray of grit into his face. He scrambled, desperate, trying to find purchase on the slick floor. His hand brushed against a jagged rock, his fingers tightening around it reflexively. Useless. Panic threatened to consume him. This wasn't a duel in a training yard. This was a brutal, ugly fight for survival in a forgotten hole. His previous life, the dueling lessons, the courtly graces—none of it mattered here. Only the instinct to live. Suddenly, a searing pain shot through his arm. The beast's tail, tipped with a bony spike, had whipped out, grazing his forearm. Blood welled, hot and sticky. He cried out, a raw, involuntary sound. *Mana Absorption. Raw, chaotic energy.* The system's prompt from moments ago flashed in his mind. He’d absorbed it, then vomited it out. Crude. Inefficient. A desperate reaction, not a skill. He watched the beast recoil slightly, savoring its small victory, before preparing another lunge. Its body pulsed with the same dark, virulent mana he’d felt before. It wasn’t just a creature; it was a conduit, a living wellspring of corrupt energy. A thought, sharp and sudden, pierced through the haze of fear. His betrayers. They hadn’t just taken his life; they’d *drained* him. Drained his inheritance, his future, his very essence. They hadn’t just absorbed his trust and thrown it back; they’d consumed it, leaving him hollow. Mana Absorption. It wasn't just about taking in and discharging. It was about *taking*. Permanently. Focus. He had to focus. His eyes locked onto the beast. The throbbing vein at his temple pulsed with frantic energy. He needed to be more than a sponge. He needed to be a leech. A siphon. He pushed his trembling hand out, not to blast, but to *pull*. He imagined threads, invisible tendrils of his own nascent mana, reaching out, not to grapple, but to penetrate. To hook into the beast's pulsing energy, its very life force. At first, nothing. The beast snarled, its muscular body coiling. Then, a flicker. A faint, almost imperceptible tremor ran through the creature. Kaelen felt a faint tug, like a distant current in the dark ocean of his consciousness. He pushed harder, pouring every ounce of his will into the action. Vision blurred. He felt a profound drain on his own meagre energy, but it was accompanied by a subtle, growing warmth in his outstretched hand. The beast shrieked, a high-pitched, unnatural sound that echoed through the cavern. Its crimson eyes widened, not with rage, but with confusion, then agony. Its scales, once glistening with a dark sheen, began to dull. The vibrant crimson in its eyes faded, replaced by a milky glaze. Its powerful limbs, moments ago taut with aggressive intent, now trembled. The raw mana within its body, the same energy that had fueled its attack, was being pulled, slowly but surely, into Kaelen. It was agonizingly slow. Every second felt like an eternity. The beast fought back, thrashing, clawing, trying to break the invisible connection. Its tail lashed wildly, striking Kaelen’s already wounded arm again, a dull thud instead of a searing pain. He bit back a cry, refusing to release his hold. Muscles screamed. Sweat plastered Kaelen’s hair to his forehead. He could feel the beast’s essence, thick and viscous, flowing into him. It wasn't the chaotic burst from before. This was controlled, deliberate. A dark, potent energy filled him, cold at first, then coalescing into a dense, invigorating warmth. The beast’s roars weakened, becoming pathetic gurgles. Its body seemed to shrink, its powerful frame collapsing inward. The scales peeled away, revealing sickly, pale flesh beneath. Its form wavered, like smoke in a breeze, before dissipating into a fine, black dust that settled on the damp floor. Silence descended. Only Kaelen's ragged breaths disturbed the quiet. He stared at the spot where the creature had been, now just a faint stain on the stone. His arm, still outstretched, trembled violently. He pulled it back, clenching his fist. The pain from the wounds on his forearm was still there, but muted. His entire body hummed with a strange, vibrant energy. *SYSTEM NOTIFICATION: 'Mana Absorption' has evolved into 'Essence Siphon'.* *Essence Siphon (Rank 1): Drain the vital essence and mana from a target, converting it into raw power and healing for the user. Effectiveness scales with proximity and mental focus. Current healing factor: Minor. Current power gain: Moderate.* *Minor Mana Vein discovered within host. Initial awakening.* The messages flashed in his vision, clear and concise. Kaelen gasped, the implications sinking in. He hadn't just defeated the beast; he’d harvested it. He closed his eyes, feeling the surge of energy, clearer, purer than any he’d felt before. His mind felt sharper, his body less weary despite the fight. The raw power was a cold, alien thing, yet it settled within him, making itself at home. He opened his eyes, examining his arm. The deeper cuts still bled, but the shallower ones had already begun to knit, a faint, iridescent glow where the skin was closing. This was a true power. One born of betrayal, refined by necessity. His family had tried to drain him, but he had learned to drain them back, or at least, their proxies. Slowly, Kaelen pushed himself away from the wall. His legs felt steadier, his vision clearer. He walked over to where the beast had dissolved. The dark dust was already fading, absorbed by the hungry dungeon floor. No corpse to examine, no trophy. Only the memory of its fading shriek and the potent energy now coursing through his veins. He scanned the immediate vicinity. The alcove was small, cramped. The previous, uncontrolled mana burst had charred some of the rock, leaving black scorch marks. He reached out, touching the wall. The stone was cold, slick with moisture. But something felt different. He ran his hand along the rough surface, feeling for any anomaly. His fingers snagged on a crumbling section, an area where the mortar between the stones was softer, almost like powder. He pushed lightly, and a small chunk of rock broke away, falling with a soft splash into a puddle below. Curiosity overriding caution, Kaelen pressed harder. More stone gave way, revealing a dark void behind it. Not solid rock. Not a natural cave. This was an opening. A passage. He widened the gap with his bare hands, ignoring the scrapes and abrasions. The stone crumbled easily, far too easily. It felt like this section of the wall had been weakened, almost intentionally, or perhaps by the passage of time and the dungeon’s slow decay. A cold, stagnant breeze wafted from the opening, carrying with it the scent of damp earth and something else, something metallic and ancient. Beyond the defeated beast, a crumbling section of the dungeon wall revealed a hidden, dark passage leading deeper into the unknown.
