Evy knelt beside Sarah's lifeless body, her tears falling onto her cold, still face. The victory felt hollow, tainted by the immense loss. She had freed Sarah from the Void Weaver's control, but in doing so, she had extinguished the last spark of life within her.

"Sarah…" Evy whispered, her voice choked with sorrow. "I'm so sorry. I tried… I tried to save you."

Silence filled the ruined temple, broken only by Evy's sobs. The obsidian skull pulsed with a faint, malevolent energy, a constant reminder of the threat that still remained.

A gentle hand touched her shoulder. Evy looked up and saw a shimmering, ethereal figure standing beside her. It was Sarah, or rather, what was left of her. Her consciousness, freed from the Void Weaver's grasp, had taken on a new, incorporeal form.

"It's alright, Evy," the spectral Sarah said, her voice soft and comforting. "You did what you had to do. You saved the moon. You saved the Earth."

"But you're gone," Evy said, her voice trembling. "I failed you."

"No, Evy," the spectral Sarah replied, shaking her head. "You didn't fail me. You gave me peace. You freed me from the Void Weaver's torment. I can finally rest."

Evy looked at the spectral Sarah, her heart filled with a mixture of grief and gratitude. She knew that Sarah was right. She had done the right thing. But it didn't make the pain any easier.

"What do I do now?" Evy asked, her voice barely audible. "How do I stop the Void Weaver?"

The spectral Sarah gestured towards the obsidian skull. "Destroy the artifact," she said. "It's the source of the Void Weaver's power. Without it, it will be weakened, vulnerable."

"But how do I destroy it?" Evy asked. "I've tried everything."

"You have to use your own power," the spectral Sarah replied. "The power that you used to free me. Channel your energy, focus your mind, and unleash a wave of pure light. It's the only way to destroy it."

Evy hesitated, unsure if she could do it. She had already pushed herself to her limits. She was exhausted, both physically and mentally. But she knew that she had no other choice. She had to try.

"Alright," she said, her voice firm. "I'll do it. But… will it hurt?"

The spectral Sarah smiled sadly. "Yes, Evy," she said. "It will hurt. But it will be worth it. You're strong, Evy. You can do this."

Evy took a deep breath and closed her eyes. She reached out with her mind, connecting with the spectral Sarah, drawing strength from her.

She remembered her training, her comrades, her duty. She remembered the faces of her loved ones, their hopes, their dreams. She remembered the beauty of the Earth, the wonder of the moon.

She opened her eyes and looked at the obsidian skull, her gaze unwavering. "I'm ready," she said, her voice filled with determination.

She focused her mind, channeling her energy, unleashing her power. A wave of pure light surged forth, engulfing the obsidian skull.

The skull pulsed with a malevolent energy, resisting the light. The air crackled with electricity, and the temple began to shake.

Evy pushed harder, pouring all her energy into the attack. The light intensified, growing brighter and brighter, until it filled the entire temple.

The obsidian skull began to crack, its surface breaking apart into jagged pieces. The malevolent energy that had emanated from it began to dissipate, fading into nothingness.

With a final, deafening roar, the obsidian skull shattered into a million pieces, its power extinguished forever.

The light subsided, and the temple fell silent. Evy stood there, panting, her body trembling. She had done it. She had destroyed the artifact. She had weakened the Void Weaver.

But as she looked around, she realized that something was wrong. The spectral Sarah was gone. Vanished without a trace.

"Sarah?" Evy whispered, her voice filled with panic. "Where are you?"

Silence.

"Sarah!" Evy shouted, her voice echoing through the temple. "Answer me!"

Still, silence.

Evy felt a wave of despair wash over her. She had destroyed the artifact, but she had lost Sarah in the process. Her final act of sacrifice had been to empower Evy, giving her the strength to destroy the skull, and in doing so, had extinguished her existence.

The Void Weaver had been weakened, but it was still out there, lurking in the shadows. And now, Evy was alone, with no one to guide her, no one to help her.

"What do I do now?" she whispered, her voice filled with hopelessness.

Suddenly, a new voice echoed in her mind. A voice that was both familiar and alien. A voice that sent a shiver down her spine.

"You know what you must do," the voice said. "You must become one with me. You must embrace the darkness. Only then will you have the power to truly save this world."

Evy gasped, her eyes widening in horror. She recognized that voice. It was the Void Weaver.

But how was it still alive? She had destroyed the artifact, the source of its power. How could it still be in her mind?

Then, she realized the truth. The Void Weaver hadn't been drawing its power solely from the obsidian skull. It had been drawing its power from her.

From her fears, her doubts, her sorrows. From the darkness that lurked within her own heart.

The Void Weaver had been using her all along, manipulating her, controlling her, turning her into a weapon against herself.

"No," Evy said, her voice trembling. "I won't let you. I'll fight you. I'll resist you."

"It's too late, Evy," the Void Weaver replied, its voice dripping with amusement. "You're already mine. You can't escape me."

The Void Weaver's influence began to spread through her mind, twisting her thoughts, corrupting her soul. She felt herself changing, becoming something dark, something twisted.

"No!" she screamed, her voice filled with terror. "Stop it! Leave me alone!"

But the Void Weaver refused to stop. It continued to consume her, to transform her, to turn her into its puppet.

As she felt her humanity fading away, she remembered something that Sarah had told her, something about hope.

"Hope is a fleeting illusion," the Void Weaver had said. "A fragile flame that is easily extinguished."

But Sarah had also said something else.

"You're strong, Evy," she had said. "You can do this."

Evy clung to that memory, to that last spark of hope. She refused to let the Void Weaver extinguish her flame.

She closed her eyes and reached out with her mind, connecting with all the people she had ever loved, all the people who had ever believed in her. She drew strength from them,
