The surge of dark energy from the pulsating orb washed over them like a black tidal wave, consuming the radiant runes that clung to chamber walls, stripping them of their supernal glow, and swallowing ancient signs in a void of evil power. The atmosphere was charged with raw, untrammelled power, the scent of ozone and decay intensifying, a suffocating pall that pinched her breath, an unspoken manifestation of the orb's growing fury. The ground trembled at their feet, the tremors vibrating with the crimson stain on her back, a dark imitation of the orb's pulsating heartbeat, an infernal music that beat devastation.
"Run!" Caius shouted, his shout shrill, his eyes wildly dilated, mirroring the crazed glare of the orb. He grabbed Elara's arm and attempted to pull her toward the other side of the room, away from the creeping shadows, a desperate flight from the creeping destruction.
The statue, bathed by the pulsating light of the orb, stood unmoving, their shining eyes fixed on Elara, an evil gaze that pierced her very soul, a grim condemnation that weighed upon her very being. "The oaths will be fulfilled," they croaked, their voice resonant in the chamber, a chilling vow of irreversible fate. "And you, Elara, are the key, the instrument of their fulfilment."
The dark energy wave pushed ahead, consuming all in its wake, the walls of stone greying away, the air quivering with unbridled power to destroy, a physical manifestation of the destruction inherent in the orb. Elara felt a feral pull, a dark vibration, a tie to the energy that both repelled and attracted her, a dark call of the siren echoing across the forbidden potential within her. It pulsed with energy that was the same as the red mark on her back, a black duplicate of her own forbidden bond, a black echo of her inner turmoil.
"I can feel it," she whispered softly, her voice a sigh, her eyes fixed on the sphere, her mind spinning with the black energy. "It's changing me, distorting me into something I don't recognise."
Caius's jaw was clenched, his face set, his eyes ablaze with a desperate determination. "We have to destroy it, Elara. Before it destroys us, before it consumes you whole."
He raised his sword, the metal glinting in the stifling darkness, a final hope of resistance against the encroaching shadows. He charged forward, going quickly and precisely, a tempest of steel and will, a final hope to sever the stream of the dark power.
The figure unleashed a jet of dark mana, a blade-sharp tendril that shot out to meet Caius's blow with eye-blinding speed. The clashing steel and dark energy shook the room, Caius stumbling backward from the impact of the blow, eyes blazing with pain, grip on his sword wavering.
Elara was swamped by raw mana inside her, a dark, feral power attuned to the energy of the orb, a dark litany of destruction that threatened to consume her from the inside out. The red discolouration across her back throbbed, a dark, rhythmic beat, as if coordinated with the beat of the orb, a dark echo of her own forbidden power, a dark beat of death. She felt a morbid urge, a dark impulse to touch the orb, to grasp its power, to surrender to its dark enveloping.
"No," she panted, her voice stretched tight, her knuckles white, her will a flimsy screen against seeping darkness. "I won't be mastered by it. I will not be a puppet to these vows."
She focused her own mana, a raw, uncontrolled power that flowed through her veins, a desperate attempt to take back the reins. She focused it at the orb, a desperate attempt to break its strength, to burst its hold, to sever the line that connected her to the dark power. The dark tide of power wavered, its progress halted, its destructive force reduced, its dark tide ebbing.
The figure's eyes narrowed, the ferocity of their regard, their light burning into her very essence, an evil mark. "You can't deny it, Elara. The vows… they hold us all in thrall. And you… you are the instrument of their fulfilment. Your very blood bears witness to it."
They unleashed a second burst of dark mana, this one forming into clusters of razor-sharp projectiles flying towards Elara, a salvo of raw, unsoiled power, a black storm of destruction.
Caius deflected the attack, holding off the projectiles with his sword, but the force of the blows pushed him back, his eyes burning with pain, his body trembling from the effort. Elara cried out in tremendous agony as a projectile tore across her arm, leaving a jagged, bleeding wound. The wound pulsed with dark power, not healing, a black brand on her skin, a mark of the orb's dark power.
"Elara!" Caius shouted, his voice tight, his eyes beseeching. "We must do something. At once! Before too late."
The orb pulsed, its light intensified, illuminating the chamber walls with long, distorted shadows, grotesque shapes that writhed and twisted in the darkness. The dark wave moved on, its destructive power gathering, consuming everything in its way, a dark tide poised to swallow them all. Elara felt a strange pull, a dark resonance, a connection to the orb that grew with every passing moment, a dark hug that would consume her.
She looked at Caius, her eyes burning with a desperate urgency, as fires burnt deep within the wells of her soul. "I have an idea," she said, her voice strained, her hands trembling. "But it is dangerous."
She focused her mana, channelling it into the red stain on her back, the mark that connected her to the dark energy of the orb. She felt a blinding pain, a burning agony that tried to consume her, to turn her into a vessel for the dark energy. The stain pulsed, its dark beat intensifying, mirroring the orb's beat, a dark concerto of devastation resonating on her skin.
"What are you doing?" Caius thundered, alarm and fear staring wide-eyed in his face.
"I'm using the link," replied Elara in a constricted voice, eyes fixed upon the orb, her will thin restraints to counter the leeching shadow. "To destroy the orb's power. To destroy the Vows."
She let loose a gush of crimson energy, raw, untamed power that flared toward the orb, a desperate last chance against encroaching night. The power struck the dark power of the orb, a searing blast of light, a shuddering explosion that shook the chamber, a maddened outburst of power that seemed to tear the chamber apart.
The orb throbbed, its light flashing, its dark energy quivering, its power exploding. The figure lurched back, their radiant eyes wide with shock, a hint of fear in their depths.
"No!" they croaked, their voice heavy with rage, a black scream that echoed through the room. "You cannot go against the vows! They are irrevocable!"
The orb began to break, its dark energy breaking, its power breaking, its dark heart shattering. The tide of dark energy receded, its destructive force lost, its dark wave breaking. But as the orb exploded, the red mark on Elara's back began to shine and spread, covering her skin in a dark, burning light, a red tide that would consume her from the inside out, and the room crumbled, walls falling, the ceiling crashing down, a crazy destruction that threatened to bury them all.
