Cold moisture dripped from the ceiling, landing with a sharp tap on Onyx’s collarbone. It seeped through his leather tunic, icy and unwelcome, but he didn't flinch. He couldn't afford to show even a flicker of weakness. Descending the jagged staircase felt like sliding down the gullet of a dead beast. Each step was a battle against the slick, ancient stone. The air grew progressively heavier, smelling of sulfur, wet moss, and old, stagnant power. Steps carved directly from black obsidian forced them to move in single file. Onyx kept his hand pressed against the damp wall, his fingers tracing the faint, grooved patterns in the stone. His palms, recently scorched and then healed by Xime’s magic, still felt overly sensitive, vibrating with a phantom hum. Xime walked just a pace behind, his proximity radiating a faint, persistent warmth that Onyx desperately tried to ignore. It was an irritatingly pleasant heat, like a hearth fire on a winter night, clashing violently with the damp chill of the cavern. "Watch your footing," Onyx muttered, his voice raspy in the damp air. He didn't turn around, keeping his gaze locked on the darkness ahead. "Always do," Xime replied, though his boots slid slightly on a wet patch of moss. A quiet grunt of frustration escaped his lips, followed by the soft rustle of his leather gear. Sweat dripped down Onyx’s temple, though the temperature was dropping with every foot they descended. His heart hammered a frantic rhythm against his ribs. The deeper they went, the more he felt the shadows in his blood starting to wake, stretching like a caged predator sensing prey. Shadows usually obeyed him without question, acting as an extension of his own will. But down here, the dark felt different. It felt heavy, liquid, and alarmingly alive. Every step downward seemed to pull them deeper into a suffocating pressure. The air was thick, making each breath a conscious effort that burned Onyx's throat. Onyx gripped the hilt of his blade, seeking the familiar comfort of cold steel. His knuckles turned white under the strain. He could feel Xime’s gaze burning into the back of his neck, intense and questioning. His skin prickled with a sudden, sharp spike of awareness. The shadows around them weren't just pool-like shapes anymore; they were reaching outward, stretching toward the walls as if trying to merge with the dark stone. Behind him, a soft, golden light flared. Xime had summoned a small ball of solar fire, letting it drift just above his shoulder to illuminate the steep descent. Golden light cut through the gloom, revealing the wet, glistening walls of the passage. Onyx flinched, his eyes adjusting painfully to the sudden brightness. "Keep that low," Onyx snapped, his jaw tightening. "We don't know what's waiting for us at the bottom. You might as well scream our location." "I'd rather see what's about to bite me than die in the dark," Xime retorted, though he dimmed the glow slightly, reducing it to a soft, amber halo. They reached the foot of the stairs, stepping onto a wide, uneven stone floor. The ceiling soared upward, disappearing into a vast, pitch-black void that felt impossibly large. Massive stone arches curved over their heads, spaced at regular intervals along the cavern walls. They looked exactly like the ribcage of an colossal, ancient beast. "Ribs," Xime whispered, his voice echoing off the distant walls. He raised his hand, throwing the light upward to reveal the massive, curving pillars of bone-white stone. Stone ribs arched over a path that sloped downward into a wider chamber. The air here was damp and smelled of old nests, scales, and something ancient and rotten. "Look at the walls," Onyx said, his voice dropping to a low whisper as he pointed a gloved finger toward the sides of the cavern. Dozens of circular alcoves were carved into the stone, each one holding a massive, rounded shape. They were petrified dragon eggs, each nearly the size of a grown man. Underneath the calcified, stony shells, a strange, dual-colored light pulsated. It was a sickening mixture of deep violet shadow and sharp, crystalline gold, swirling together in a slow, hypnotic rhythm. Sickly dark-light cast long, distorted shadows across the cavern floor. The eggs seemed to breathe, their internal magic throbbing in time with a slow, heavy heartbeat that resonated through the stone under their boots. Onyx felt a sudden, violent surge of energy run up his legs. His shadow magic flared, expanding outward without his permission, greedily drinking in the dark-light radiating from the petrified eggs. A gasp caught in his throat as the raw power flooded his veins. It was ten times stronger than anything he had ever felt, a torrent of pure, unadulterated darkness that made his vision blur. Waves of black mist began to roll off his shoulders, pooling around his boots. His shadow stretched across the cavern floor, growing larger, thicker, and far more terrifying than usual. His chest heaved as he fought to draw breath. The power was intoxicating, but it came with a terrifying price. Deep inside his skull, a dry, rasping whisper began to scrape against his thoughts. *He is weak,* the voice hissed, cold and slithering. *The sun-child is vulnerable here. Strike him down. Drain his light and take this power for yourself. You will be unstoppable.* *He will betray you eventually,* the whisper continued, growing louder, drowning out the sound of dripping water. *Everyone leaves. Everyone betrays. End him now, while he stands in your shadow.* *Take his throat,* the voice urged, a physical pressure building behind Onyx’s eyes. *Squeeze the light out of him.* Onyx squeezed his eyes shut, his hands shaking violently as he fought to block out the corruptive words. He clutched his head, his fingernails digging into his scalp through his dark hair. "Are you alright?" Xime asked, his footsteps echoing as he took a cautious step closer. "Onyx? Your shadows... they're acting strange." "Fine," Onyx lied through gritted teeth, his voice a strained growl. He forced his eyes open, but his vision was tinted with a dark, smoky haze. Sweat poured down his face, mixing with the damp moisture of the cave. His muscles locked up, stiffening as he threw up every mental barrier he possessed to keep the darkness from taking over. Black veins began to web across the backs of his hands, spreading upward under his leather sleeves. He could feel the corruption crawling up his neck, cold and invasive, like frozen needles piercing his skin. They wanted him to destroy Xime. The ancient, corrupted magic in this cave wanted to consume the last remaining light, and it was using his own body as the weapon. *He is a threat to you,* the whisper pleaded, softer now, almost comforting. *If you do not kill him, his light will eventually burn you to ash. Remember the pain. Remember the abandonment.* *Put an end to it. Now.* Onyx let out a low, animalistic groan, his body trembling as he fought against his own limbs. He wanted to strike out, to unleash the devastating storm of shadows building in his chest, but he forced himself to hold back. "Onyx, talk to me," Xime demanded, his voice dropping all pretense of rivalry, replaced by a sharp, genuine concern. He stepped forward, reaching out a hand. "Stay back!" Onyx roared, his voice sounding distorted, layered with a dark, echoing undertone that wasn't his own. He retreated a step, his boot slipping on the wet stone. Step by step, the darkness was winning. It was a physical weight crushing his lungs, a black tide rising to drown his consciousness. "You're losing control," Xime said, his eyes widening as he saw the black mist swirling aggressively around Onyx’s body. "I said, stay back!" Onyx gasped, his vision narrowing to a pinpoint. He couldn't trust himself. If Xime got too close, the shadows would lash out on instinct, tearing the light wielder apart. Darkness surged, a violent wave of black energy exploding outward from Onyx’s chest. The force of it cracked the stone floor beneath his feet, sending a tremor through the cavern. Pain exploded behind his eyes, sharp and blinding. His legs gave out beneath him, the sheer pressure of containing the corrupted power proving too much to bear. He stumbled forward, his knees buckling. He braced for the impact of the hard, wet stone, ready to let the darkness swallow him whole. His descent was abruptly halted. Two powerful, warm arms wrapped around his torso, catching him before he could hit the ground. Black, smoky tendrils immediately lashed out, wrapping around Xime’s forearms, burning the light wielder's skin. Xime hissed in pain, his jaw clenching, but he refused to let go, pulling Onyx tightly against his chest. Xime held on, his body radiating a fierce, golden warmth that fought back the encroaching cold of the shadow magic. The contrast of their elements sent a violent shockwave through both of them, a raw, physical jolt that made Onyx’s breath hitch. Strong fingers gripped Onyx's shoulders, forcing him to stand. Xime leaned in close, his golden eyes blazing with a mixture of pain, determination, and intense focus. Looking down, Xime saw the thick, black veins pulsing violently up Onyx's neck, reaching all the way to his jawline. Xime catches Onyx stumbling and notices his veins are turning black; he demands, 'Are you going to use that power to kill me, or do you want me to help you carry it?'
