The bridge stretched on forever.
Every step I took felt heavier than the last, as if the Void itself was trying to pull me back. The sword in my hand hummed with a faint, steady warmth, and I clung to it like a lifeline. The only sound was my own breathing, ragged and uneven, echoing off the cavern walls.
Ahead of me, the platform grew larger. I could see Kael more clearly now—his body translucent, flickering like a candle in the wind. The chains that bound him were made of light, pure and blinding, and they seemed to pulse with a rhythm that matched my heartbeat.
Almost there. Almost there.
But I knew better than to relax. The Void had a way of throwing one last obstacle in your path when you least expected it.
I reached the platform.
It was circular, maybe twenty meters across, its surface carved from the same black stone as the bridge. At its center stood the pillar where Kael was imprisoned, and around the pillar, the chains of light coiled like serpents.
Kael opened his eyes when I stepped onto the platform.
His eyes were the same color as the chains—bright, burning, almost painful to look at. But beneath that light, I could see him. The real him. Tired. Broken. But still there.
"Eren," he said. His voice was barely a whisper, like it was coming from very far away. "You shouldn't have come."
"I made a promise," I said.
He tried to smile. It came out as a grimace. "Promises are dangerous things. Especially in the Void."
"I know." I took a step closer. The chains pulsed, and I felt a wave of heat wash over me. "I'm going to get you out of here."
Kael shook his head. "You can't. The chains are part of the Void. They're bound to my soul. If you break them, you'll break me."
I froze. "What?"
"The Void doesn't imprison you with chains," he said. "It imprisons you with yourself. The chains are made of my own power. My own will. They're the only thing keeping me from becoming a monster."
I stared at him. "I don't understand."
He looked at me with those burning eyes. "Five years, Eren. Five years in the Void. It's changed me. Corrupted me. I've done things—terrible things—to survive. The chains are the only thing holding back the darkness inside me. If you break them..."
He trailed off.
"If I break them, what?"
"Then I become what the Void wanted me to be," he said. "A vessel. A weapon. A thing that destroys everything it touches."
I felt my stomach drop. "There has to be another way."
"There isn't." His voice was firm, final. "You have to leave. Now. Before it's too late."
"No."
The word came out before I could stop it. It was sharp, defiant, and it echoed off the cavern walls.
"No," I said again. "I didn't come all this way to give up. I didn't fight through that serpent, through the Void, through everything, just to turn around and leave you here."
Kael stared at me. "You don't understand what you're saying."
"Then make me understand," I said. "Tell me what to do. Tell me how to save you."
He was quiet for a long moment. The chains pulsed, their light flickering like a dying flame.
"The only way to save me," he finally said, "is to separate the Void's corruption from my soul. To pull the darkness out of me and destroy it."
"Then that's what I'll do."
"You don't have that kind of power."
"Maybe not," I said. "But I have to try."
I raised the black sword. It hummed in my hand, its blade gleaming with a dark, hungry light.
"Hold still," I said. "This might hurt."
I swung the sword at the chains.
The blade connected with a sound like shattering glass. Light exploded outward, blinding and hot, and I felt the shockwave throw me backward. I slammed into the ground, the sword flying from my hand, and I could hear Kael screaming—a terrible, anguished sound that tore through the cavern and into my soul.
"KAEL!"
I scrambled to my feet. The light was fading, and through the afterimages, I could see him.
The chains were gone.
But so was the man I'd been trying to save.
Kael's body was no longer translucent. It was solid, real, human—but wrong. His skin was pale as ash, and his eyes, his beautiful burning eyes, had turned black. Complete, total, empty black.
And he was smiling.
"Eren," he said. His voice was smooth, calm, dripping with mockery. "Thank you. Thank you for freeing me."
I took a step back. "That's not you."
"Of course it's me," he said. "It's always been me. The real me. The me the Void wanted me to be."
He raised his hand. Shadows curled around his fingers, twisting and writhing like living things.
"I was so afraid," he said. "So afraid of becoming this. But now that I am..." He laughed. "Now that I am, I feel wonderful."
"You're lying," I said. "I know you're lying. The real Kael is still in there."
The thing that wore Kael's face tilted its head. "Is he? Let me show you."
It raised both hands. Shadows exploded outward, filling the cavern, and I felt myself being lifted off my feet. The shadows wrapped around me, crushing me, squeezing the breath from my lungs.
"Look at me," it said. "Look at what you've done."
I tried to resist. I tried to call on the Void's power. But the shadows were too strong, too heavy, too wrong.
"Please," I gasped. "Please, Kael. Fight it."
The thing laughed again. "Kael is gone. There's only me now. And soon—" It leaned closer, its black eyes boring into mine. "—there will only be me. Everywhere. Forever."
Then something strange happened.
The shadows around me loosened. Just slightly. Just enough for me to breathe.
And I heard a voice—quiet, broken, but unmistakably Kael.
"Eren..."
The thing's expression flickered. For a moment—just a moment—I saw the real Kael behind those black eyes. Desperate. Terrified.
"Run. Please. Run."
"I'm not going to run," I said. "I'm going to save you."
"You can't—"
"Yes, I can." I reached out, my hand trembling. "I just have to reach you."
The shadows tightened again. The thing's face twisted with rage.
"You think you can save him?" it snarled. "You can't save anyone. You couldn't even save yourself."
"Maybe not," I said. "But I'm going to try anyway."
I closed my eyes. I focused on the hum in my chest, the pulse of the Void that had been with me since the night the sky broke. I felt it respond, felt it surge, felt it listen.
And then I pushed.
Not outward. Not at the thing that wore Kael's face.
Inward.
Toward the light I could still see in the darkness. The tiny, flickering flame that was Kael's soul.
"I'm coming," I thought. "Hold on. I'm coming."
The world dissolved.
I was no longer in the cavern. I was somewhere else—a place of pure, endless light, so bright it almost hurt to look at. And in the center of that light, I saw him.
Kael.
Not the corrupted thing. The real Kael. Kneeling on the ground, his hands over his face, sobbing.
"I couldn't stop it," he whispered. "I tried. I tried so hard. But I couldn't stop it."
I knelt beside him. "Kael. Look at me."
He looked up. His eyes were human again—warm, sad, full of pain.
"Eren," he said. "What have I done?"
"You didn't do anything," I said. "The Void did this to you. It wasn't your fault."
"But I—"
"No." I grabbed his shoulders. "Listen to me. I'm not going to let you give up. I'm not going to leave you here. We're going to get out of this together."
He stared at me. "How? There's no way out. The corruption is part of me now. It's never going to leave."
"There's always a way," I said. "I just have to find it."
I closed my eyes. I thought about the sword—the black sword that had appeared from my arm. I thought about the chains of light, the corruption, the Void.
And then I felt it.
A connection. A thread. Something that linked me to Kael, to the corruption, to the Void itself.
I opened my eyes.
"Kael," I said. "I think I know what to do."
I grabbed his hand.
He flinched, tried to pull away. "Eren, don't. If you touch me, the corruption will spread to you. It'll—"
"I don't care," I said. "Trust me."
He hesitated. Then, slowly, he nodded.
I closed my eyes. I focused on the connection between us—the thread of energy that linked his soul to the Void. And then I followed it.
Down. Deep down. Into the heart of the corruption.
It was cold. Dark. Empty. The Void was all around me, pressing in on all sides, trying to consume me. But I held on. I held on to Kael's hand, to the thread of light that still connected us.
And I started to pull.
The corruption fought me.
It was a living thing, a monster of shadow and malice. It wrapped around me, tried to choke me, tried to drag me down into the darkness. But I didn't let go.
I thought about my mother. About Lyra. About Mira and Zed and all the people I'd promised to protect.
I thought about Kael. About the man who'd given everything to save the world.
And I pulled.
"Come on," I growled. "Come on!"
The corruption screamed. It was a terrible sound, filled with rage and fear, and it made my ears bleed and my head spin. But I didn't stop.
I kept pulling.
And then—impossibly—the darkness began to fade.
I opened my eyes.
I was back in the cavern, on my knees, gasping for breath. The black sword was in my hand, its blade covered in shadows that were slowly evaporating into nothing.
And in front of me, Kael was kneeling.
He was whole. Human. His eyes were their normal color, warm and tired and full of tears.
"Eren," he said. "You... you did it. You actually did it."
I grinned. It was a weak, exhausted grin, but it was real.
"Told you," I said. "I'm a science student. We figure things out."
He laughed. It was a broken sound, half sob, but it was beautiful.
And then the cavern began to shake.
To be continued...
