The roar from the abyss seemed to echo through Isabella's very soul, its primal ferocity shaking the cavern walls. Dust and debris rained from above as the swirling vortex of darkness within the doorway grew more menacing. Its pull was palpable, a gravitational force threatening to drag them in.
Malrik, still weak, forced himself to his feet. His hand clutched his side, but his crimson eyes burned with determination. "We have to close it," he said, his voice hoarse. "If that thing escapes, it'll consume everything."
Isabella nodded, though her hands trembled. She could still feel the lingering cold of the shadow's presence, and the Heartstone in her grasp was now dim, its power almost entirely spent. "How? The stone... it's almost gone."
Malrik glanced at the vortex, his expression grim. "There's another way, but it's not something you're going to like."
"What is it?" she asked, her voice barely above a whisper.
Before Malrik could answer, the vortex surged, and a massive clawed hand emerged. It was formed of pure darkness, its edges crackling with energy. The ground beneath them splintered as the creature within struggled to break free.
"We don't have time!" Malrik shouted. "Get ready to run!"
Isabella's eyes widened. "Run? Where—"
Her question was cut off as the claw slammed into the ground, sending a shockwave through the cavern. She was thrown backward, her head spinning as she hit the floor. Malrik grabbed her arm, pulling her to her feet as chunks of rock fell around them.
"The seals were meant to keep it trapped," Malrik said as they stumbled toward the edge of the chamber. "The only way to reinforce them now is a blood sacrifice."
Isabella froze, her stomach lurching. "A sacrifice? No! There has to be another way."
Malrik didn't respond. Instead, he unsheathed his blade, the dark weapon glinting ominously in the faint light. He turned to face the vortex, his expression one of grim resolve. "This is my burden. I was the one who let it weaken. I'll fix it."
"Wait!" Isabella grabbed his arm, her voice desperate. "You don't have to do this! We'll find another way, I promise!"
"There isn't time," he said quietly. His eyes softened, the fierce warrior giving way to the man she had come to trust. "You have to live, Isabella. You're the only one who can finish this."
Before she could argue further, the creature roared again, and a second claw burst through the vortex. The entire cavern trembled, and cracks spread across the walls like spiderwebs. The creature's glowing red eyes became visible, twin orbs of hatred staring directly at them.
Malrik shoved Isabella behind him. "Go!" he shouted. "Find Caelum and get out of here!"
"I'm not leaving you!" she cried, tears streaming down her face.
"You don't have a choice!" Malrik roared back. He turned and charged toward the vortex, his blade gleaming as he slashed at the creature's claw. The force of his attack sent a shockwave through the air, momentarily driving the creature back.
Isabella's heart clenched as she watched him fight. The Malrik she knew was strong, but even he was no match for the monstrosity emerging from the abyss. Yet he didn't falter. Each swing of his blade was precise, fueled by a determination she couldn't begin to understand.
Suddenly, the vortex flared, and tendrils of darkness shot out, wrapping around Malrik's arms and legs. He struggled, his blade clattering to the ground as he was lifted into the air. The creature let out a triumphant roar, its claws reaching for him.
"Malrik!" Isabella screamed, her voice raw.
He turned his head, his crimson eyes meeting hers one last time. "Stay strong," he said, his voice barely audible over the chaos.
The vortex surged, and Malrik was pulled into its depths. The tendrils and claws retracted, and the doorway began to close, the runes glowing with renewed intensity. The cavern fell silent, save for Isabella's ragged breathing.
She sank to her knees, the Heartstone slipping from her grasp. The weight of what had just happened pressed down on her, suffocating in its finality. But her grief was short-lived. The ground trembled once more, and the runes on the doorway flickered erratically.
"No," she whispered, her voice shaking. "It's not over."
A low growl echoed through the cavern, and cracks spread across the sealing runes. The vortex began to stir again, its energy unstable. From the depths came a voice, deep and resonant, filled with malice.
"You cannot stop me, little mortal. The seals are broken, and your sacrifice is meaningless. I am coming for you."
Isabella's blood ran cold as the doorway began to shatter. The creature was not defeated—it was enraged. And it was free.
