The absence of everything was more terrifying than any darkness Lyra had ever imagined. There was no up, no down, no light, no sound. Just a chilling, infinite nothingness. Her hand, still clenched in what she thought was Caelum's, felt cold and strangely insubstantial.
"Caelum?" she whispered again, her voice a fragile echo in the void. "Are you there?"
No answer.
Panic began to rise in her chest, a suffocating wave of fear. She tried to move, to orient herself, but there was nothing to push against, nothing to hold onto. She felt like she was floating, lost in an endless sea of emptiness.
Then, a faint flicker of light appeared in the distance, a tiny pinprick in the overwhelming darkness. It was a soft, purplish glow, familiar and comforting.
"Caelum?" she called out, her voice filled with hope.
The light grew brighter, and a figure began to emerge from the void. It was Caelum, but he looked different. His eyes, usually filled with warmth and kindness, were now shadowed and distant. The purplish glow around him was erratic, flickering and dimming like a dying ember.
"Lyra," he said, his voice strained and hollow. "We're… we're not in Umbra."
"Where are we?" she asked, her voice trembling.
"Between worlds," he replied, his gaze fixed on something beyond her. "The Keepers… they interfered. They disrupted the passage."
"The Keepers?" she asked, remembering the fear in his voice. "Who are they?"
"Ancient beings," he said, his voice barely a whisper. "Guardians of the void. They… they don't like trespassers."
A low, guttural growl echoed through the emptiness, a sound that seemed to vibrate in her very bones. Lyra's heart pounded. She turned, searching the darkness, but she saw nothing.
"They're here," Caelum whispered, his eyes widening. "We have to leave."
He reached out, his hand trembling, and grasped her arm. "I can still open a portal to Umbra, but it will be unstable. We have to be quick."
He began to chant in a language Lyra didn't understand, his voice echoing through the void. The purplish glow around him intensified, forming a swirling vortex of energy.
"Hold on tight," he said, his voice strained. "This might be… rough."
The vortex pulsed, and the void around them began to distort, twisting and warping like a reflection in a shattered mirror. Lyra felt a sickening lurch, like her body was being pulled apart and reassembled.
Suddenly, a dark, shadowy figure emerged from the depths of the void, its eyes burning with malevolent energy. It was tall and gaunt, with long, skeletal fingers that reached out towards them.
"Trespassers," it hissed, its voice a grating rasp. "You will not escape."
Caelum's portal flickered, threatening to collapse. He strained against the Keepers hold. "Go Lyra! Now!"
Lyra hesitated, her gaze fixed on Caelum's desperate face. She couldn't leave him.
Then, the Keeper's hand closed around Caelum's arm, its grip like ice. A sharp cry escaped his lips, and the portal began to unravel.
"Go!" he yelled, his voice filled with pain. "Before it's too late!"
With a heart-wrenching pang, Lyra realized she had no choice. She took a step towards the collapsing portal, her gaze fixed on Caelum's desperate face.
As she stepped through the portal, the void around her dissolved, replaced by a blinding flash of light. Then, darkness. But this darkness was different, it was thick and earthy, and the air was filled with the scent of damp soil and decaying leaves. She had made it. But where was Caelum? And what had she just stepped into?
