Thud-thud. Thud-thud. Inside Onyx’s chest, a double beat vibrated. His own slow, cautious rhythm collided with a wilder, more frantic pulse. It belonged to Xime. The connection was violent, an unwelcome intrusion that seeped straight into his bones, forcing him to feel things he had spent a lifetime trying to bury. "Get your hand off me," Onyx muttered, though he couldn't bring himself to pull away. His fingers twitched against his leather trousers, aching to put distance between them, yet paralyzed by a strange, magnetic pull that defied his will. Xime stood frozen. His golden eyes were wide, staring down at the glowing brands burning through their shirts. The mark on Xime's chest mirrored the one on Onyx’s, pulsing with a faint, warm light that pierced the gloom of the crystal cave. The magic felt alive, a golden thread sewing their hearts together. "I can't," Xime whispered. His voice was a ragged breath, barely audible over the hum of the crystals. "If I pull back, it feels like my lungs are collapsing. Like my air is being sucked right out of my throat." Sweat beaded along Xime’s collarbone, glistening in the dim, purple light of the geode. Onyx watched the rapid rise and fall of the younger man's chest. Every fast, panicked flutter of Xime’s heart translated directly into Onyx’s own ribcage, making his own pulse race in response. It was a physical invasion of the worst kind, stripping away his hard-won control and leaving him exposed. "We have to move," Onyx said, gritting his teeth to block out the sudden rush of warmth flooding his veins. He hated how good that warmth felt. He hated how easily it chased away the biting, familiar chill of his shadow magic, threatening to melt his icy defenses. "Where?" Xime asked. He looked up, his face pale, his lower lip trembling slightly as he clutched at the tear in his tunic. "Out," Onyx replied. He pointed toward the narrow opening of the crystal geode. Beyond that jagged threshold lay a sheer drop, a thin ledge of stone clinging to the side of the obsidian mountain. It was the only way forward, and it looked entirely unforgiving. Dragging his boots across the glittering floor, Onyx led the way. Every step felt heavier now. He wasn't just carrying his own weight; he was carrying the physical echo of Xime’s presence, a constant reminder that he was no longer alone in his own body. The forced proximity was suffocating, yet strangely grounding. Shadows curled around Onyx's fingers, reacting to his rising irritation. Yet, the moment his dark magic flared, a sharp spike of anxiety shot through his chest. It didn't belong to him. He looked back and saw Xime wincing, clutching his own sternum as if he had been struck by a physical blow. "Your magic," Xime gasped, his knees buckling slightly. "It feels like ice dripping straight into my veins. Calm down, Onyx. Please." "I am calm," Onyx snapped, though his jaw clamped tight. In truth, his mind was spinning. Trust was a luxury he had discarded years ago during the Great Eclipse, when the people he trusted most had left him to rot in the dark. Letting someone this close, literally tying their life forces together, was his absolute worst nightmare. He had spent his entire life building walls, and now, a single magic brand had shattered them all, leaving him raw. "Let’s just get through this pass," Xime said, taking a deep, shaky breath that vibrated in Onyx's chest. "The sooner we find a way to break this link, the better." "Agreed," Onyx lied. A strange, unbidden pang of disappointment flared in his chest, hot and sharp. It wasn't his own emotion; it was Xime's. The realization hit him like a physical blow: Xime actually felt hurt by his coldness, and the linked heartbeat didn't lie. --- Wind screamed across the open face of the mountain, instantly whipping Onyx's dark hair across his eyes. The air was thin, freezing, and tasted of sulfur and ash. The sheer height of the peak was dizzying, offering no protection from the elements. Step by step, they edged out of the geode’s protective mouth. Below them, a dizzying drop descended into the twilight-choked valley. Gray clouds swirled like a boiling pot thousands of feet below, hiding the jagged rocks that waited for any misstep. The path was nothing more than a lip of crumbling stone. "Keep your back to the wall," Onyx instructed. He pressed his palms against the cold, rough stone, sliding sideways along the path. It was barely wide enough for a single boot, requiring absolute focus and balance. Behind him, Xime made a small, choking sound. Suddenly, Onyx’s heart hammered violently. A wave of sheer, unadulterated terror flooded his system, so intense his knees almost buckled. He gasped, clutching his chest, his vision swimming with a sudden rush of vertigo that didn't belong to him. "Xime?" Onyx turned his head, his eyes scanning the narrow path behind him. Xime had stopped dead in his tracks. He was pressed flat against the rock, his fingers digging into the crevices until his knuckles turned white and bled. His eyes were locked on the vast, empty air beneath his boots, his face completely drained of color. "I... I can't," Xime choked out. His pupils were completely dilated, swallowing the gold of his irises. His body was trembling so violently that small pebbles rolled off the ledge, clattering into the abyss. "Don't look down," Onyx ordered, keeping his voice firm. "Look at me, Xime. Only look at me." "No," Xime whimpered, his head shaking back and forth. "The world is spinning. I'm going to fall. Onyx, I can't breathe. My chest... it's too tight. I can't get any air in." Through their shared bond, Onyx felt Xime’s lungs seizing. A suffocating pressure clamped down on his own chest, making it hard to draw air. Xime was hyperventilating, and the panic was physically dragging Onyx down into the same dark abyss, threatening to make him lose his footing. "Xime, listen to my voice," Onyx said. He took a cautious, agonizingly slow step back toward the radiant light wielder. Every instinct yelled at him to keep moving, to save himself, but he couldn't leave Xime behind. "Stay away," Xime pleaded, his chest heaving. "If you move, we'll both slip. Just go on without me. Save yourself." "I'm not leaving you," Onyx said. His voice, usually sharp and laced with sarcasm, softened. He didn't recognize the tone coming from his own mouth. It was a gentle, grounding murmur, a voice he hadn't used since he was a child, before the world taught him to be cruel. --- Carefully, Onyx closed the remaining distance between them. The narrow ledge left absolutely no room, forcing him to press his chest directly against Xime’s side, anchoring them both against the mountain. He could feel the intense heat radiating from the other man, a sharp contrast to the freezing wind. "Look at me," Onyx commanded softly, his voice steady. Slowly, Xime turned his face. Tears of frustration and terror brightened his golden eyes, spilling over his pale cheeks. His lips were parted, gasping for air that wouldn't come, his hands trembling against the rough stone. "Put your hands on my shoulders," Onyx said, his voice a steady anchor in the howling wind. "Onyx..." "Do it," Onyx insisted, his voice dropping to a low, soothing purr. "Focus on me. Only me. Ignore the wind. Ignore the drop." Trembling violently, Xime released his grip on the stone wall and placed his palms on Onyx's leather-clad shoulders. He was shaking so hard his teeth clicked, his entire body radiating a frantic, erratic heat that seeped through Onyx's clothes. "Now, breathe," Onyx whispered. He took a deep, exaggerated breath, letting his chest expand against Xime's. "Match me. In." Xime tried, but his breath caught in his throat, ending in a broken, desperate sob. "No, don't focus on the air," Onyx murmured. He reached up, his leather-gloved hands gently cupping Xime’s jaw, holding his head still. The heat radiating from Xime’s skin was intense, melting the frost on Onyx's gloves. "Focus on the pulse. Feel it?" Under Onyx’s palms, Xime’s throat bobbed as he swallowed, his gaze locked onto Onyx's dark eyes. "We are the same right now," Onyx whispered, his gaze locking onto Xime's terrified eyes. "My heart is yours. Yours is mine. Let me carry the weight of this height for you. Let my chest do the work." Slowly, Onyx slowed his own breathing. He forced his mind to go completely blank, channeling the quiet, deep stillness of his shadow magic. He projected a deep, tranquil calm, letting it flow through the physical link between them, pushing back the frantic waves of panic. Through the physical bond, the frantic thudding in Xime’s chest began to slow, mirroring Onyx’s calm rhythm. The violent trembling began to subside, replaced by a quiet, shared warmth. The terror receded, leaving behind a profound, heavy silence. "There you go," Onyx murmured, his thumb brushing over Xime’s wet cheekbone. "Just like that. Keep your eyes on mine. Don't look anywhere else." "Why are you being nice to me?" Xime whispered. His voice was raw, but his breathing had finally steadied, his hands gripping Onyx's shoulders with a soft, desperate strength. "Because you're useless to me if you fall off this mountain," Onyx replied. But there was no heat in the words, only a quiet, protective warmth that Xime could undoubtedly feel through their connection. In that quiet moment, Onyx realized something terrifying. The walls he had spent a lifetime building were completely useless. He could feel Xime's sudden wave of profound affection and gratitude washing over him, melting the cold core of his heart. Xime wasn't just an annoying rival anymore. He was someone Onyx wanted to protect. He was indispensable, and the thought of losing him sent a cold dread through his soul that had nothing to do with magic. --- "Can you walk now?" Onyx asked, his hands lingering on Xime's jaw for a second too long before he reluctantly let go. "Yeah," Xime nodded, a faint flush creeping up his pale cheeks. "Yeah, I think I can." "Good. Keep your hands on my waist. Don't look down." Nodding, Xime stepped close, his hands gripping the leather at Onyx’s hips. The physical contact sent a jolt of electricity straight to Onyx's core, but he kept his steps measured and steady, guiding them along the path. They shuffled along the treacherous ledge, moving in perfect, agonizing synchronization. Every step was a shared effort, their heartbeats chiming in a steady, united rhythm that kept the panic at bay. The connection that had felt like a curse only moments ago now felt like a lifeline. Suddenly, a deep, rumbling vibration shook the stone beneath their feet. Onyx froze. He felt Xime’s heart rate spike again, but this time, Onyx’s own instincts flared with danger. A massive shadow-cyclone erupts from the valley below, carrying a horde of flying twilight-beasts straight toward their narrow ledge.
