BackThunder’s Claim

Chapter 28 – Prison of Bone

THUNDER

The bone-cage wasn’t just a prison.

It was a tomb.

Carved from the ribs of ancient dragons, the walls curved inward like a ribcage, veined with silver sigils that pulsed with anti-magic. The air was thick with the scent of decay and old blood, cold enough to make my breath fog, heavy enough to press down on my chest. No light. No sound. No magic. Just silence. Heavy. Thick. Charged.

I sat curled against the wall, my arms wrapped around my knees, my underclothes damp with sweat and something darker—fear, maybe, or the residue of the bond being slowly, methodically torn apart. The Dusk-mark beneath my collarbone flared weakly, a dying ember in the dark. The sigil on my hip—Kael’s mark—was dull, lifeless, like it had been scraped from my skin and buried.

They’d taken everything.

My tunic. My boots. My journal. The locket. The letter.

Everything that tethered me to the truth, to the past, to him.

And now?

Now I was just… here.

Alone.

And the bond—

The bond screamed.

Not a pulse. Not a surge.

A rip.

Like a knife through flesh. Like a blade through bone. Like a curse tearing through blood. I gasped, my back arching, my hands fisting in the air, but there was nothing to hold. Nothing to fight. Just pain. Raw. Unfiltered. Real.

“Kael—” I whispered, my voice breaking.

No answer.

Just silence.

And then—

Visions.

Not fever. Not hallucination.

Memory.

Kael, carrying me through the forest, my legs wrapped around his waist, his breath hot on my neck. Riven, crouched beside me, handing me a cloth, saying, “He didn’t sleep. Not once. Never seen him like this.” Nyx, her crimson eyes glowing in the moonlight, saying, “Careful, girl. He’ll burn you alive… or love you to death.” Cassian, holding out the locket, saying, “For when you’re ready.” My mother, her voice trembling, saying, “Forgive them. Forgive Kael. Forgive Cassian. Forgive me.”

And then—

Darkness.

Real sleep.

Not peaceful. Not healing.

Drowning.

I didn’t know how long I was there. Hours? Days? Time didn’t matter. Just pain. Just silence. Just the bond, ripping, tearing, dying.

And then—

A sound.

From the corridor.

Footsteps. Slow. Deliberate. Crisp on stone.

I didn’t move. Didn’t speak. Just lay there, my body broken, my magic drained, my breath coming in ragged gasps.

The door opened.

Not guards.

Not the High Elder.

Him.

Cassian.

He stepped inside—tall, broad-shouldered, dressed in a coat of midnight blue etched with silver sigils. His hair was silver, like Kael’s, but longer, tied back with a black ribbon. His face was sharp, angular, his eyes—

Gods.

His eyes.

They were the same as mine. Storm-gray, flecked with gold, like lightning in a thundercloud. I’d seen them every day in the mirror. But I’d never known whose they were.

Now I did.

He didn’t speak. Just stepped closer, his boots silent on stone, his presence a quiet storm in the room.

“You’re alive,” he said, voice low, smooth, like smoke over embers.

“Barely,” I whispered.

“Good.” He crouched beside me, his storm-gray eyes holding mine. “Because you’re not done yet.”

“They’re going to kill me,” I said. “And you’re not going to stop them.”

“No,” he said. “I’m not.”

My breath caught.

“But he will,” Cassian said. “Kael. He’ll break every law. Burn every oath. Storm the prison. And when he does? When he rips the bond-seal from his finger and lets the decay take him? When he fights through the guards, through the magic, through the bone? That’s when you have to be ready.”

“Ready for what?”

“To choose,” he said. “Not vengeance. Not hate. Not even love. But truth. To break the curse, the heart must open. The body must yield. The soul must claim its other half. And you? You’re not just his other half. You’re mine too. And when he comes for you, when he breaks the cage, when he pulls you into his arms—you have to choose us. Both of us. Or the bond dies. And you die with it.”

My throat tightened.

“And if I can’t?” I whispered.

“Then you die,” he said. “And he dies with you. And the High Queen wins.”

“And you?” I asked. “Do you die with me?”

He didn’t answer. Just reached out, his fingers brushing the Dusk-mark beneath my collarbone. The sigil flared—weak, faint—but alive. “I’ve spent twenty years searching for you,” he said, voice rough. “Hiding you. Protecting you. And now? Now I’m letting you go. Because if I don’t, he won’t come. And if he doesn’t come, you’ll die in this cage. And I can’t lose you. Not now. Not ever.”

My breath hitched.

“So when he comes,” Cassian said, standing, “don’t fight. Don’t run. Just be. Just choose. And for the first time in your life—let go.”

Then he was gone, vanishing into the shadows like smoke.

The silence that followed was heavier than any spell.

And then—

Sleep.

Not the fractured, fevered dreams of the past nights.

Real sleep.

Deep. Heavy. Peaceful.

I didn’t wake until I heard it.

Not a scream.

Not a whisper.

A roar.

Not human. Not Fae.

Kael.

And the bond—

The bond surged.

Not a pulse. Not a surge.

A explosion.

Fire. Real. Molten. Unstoppable.

He was coming.

And this time, I wasn’t running.

This time, I was ready.

The door exploded inward.

Not opened. Not unlocked.

Shattered.

Blackened bone splintered, silver sigils cracking like glass, the anti-magic wards screaming as they were torn apart. Dust rained down, thick and choking, the air suddenly alive with ozone and embers. And then—

He stepped through.

Kael.

His coat was torn, his silver hair loose, his face pale—too pale—but his silver eyes were dark with something raw. Not just anger. Not just power.

Need.

He didn’t speak. Just stepped forward, his boots silent on stone, his magic coiling in the air like a storm. The decay from the Oath Chamber still marred his flesh—blackened veins crawling up his arm, magic flickering like a dying flame—but he moved like a god. Like a force of nature. Like mine.

“Kael—” I whispered, my voice breaking.

He didn’t answer. Just dropped to his knees before me, his hands framing my face, his thumbs brushing my cheeks. His breath hitched. His eyes filled with something I couldn’t name—relief, maybe, or grief, or love so deep it was a wound.

“You’re alive,” he murmured, his voice rough.

“Barely,” I said.

“Good.” He pulled me into his arms, his body a furnace against mine, his breath warm on my neck. The bond erupted—a wave of heat crashing through me so intense I gasped. My breath hitched. My skin burned. My body ached for his touch, for his mouth, for the claim I’d been running from since the moment I’d walked into the Iron Spire.

“You don’t have to fight it,” he murmured, his lips brushing my ear. “You don’t have to pretend. You can stop.”

“I can’t—”

“Yes, you can.” He turned me, pressing me against the wall, his body a furnace against mine. One hand slid to my hip, over the sigil, the other tangling in my hair, tilting my head back. His silver eyes held mine—dark, intense, needing. “You came to me. You let me hold you. You let me in. That was the first step.”

“It wasn’t—”

“It was.” His lips traced my jawline, slow, deliberate. “And now? Now you’re ready for the next one.”

“I’m not—”

“You are.” He kissed me—soft, slow, full of promise. “You’re ready to be mine.”

The bond erupted.

Not a pulse. Not a surge.

An explosion.

Fire. Real. Molten. Unstoppable. A wave of heat ripped through me, starting where our mouths met and exploding outward—up my spine, across my chest, down my limbs. I gasped, but he swallowed the sound, his tongue delving deeper, his hands tightening in my hair.

His hand slid under my tunic, his fingers tracing the curve of my waist, the dip of my spine, the swell of my hip. The sigil flared beneath his touch, heat pooling low in my belly, spreading through my limbs. I arched into him, my hands fisting in his coat, dragging him closer.

“Kael—”

“Shh.” His mouth left mine, trailing down my neck, his teeth scraping my pulse point, his tongue soothing the sting. “Let me in.”

“I can’t—”

“You already did.” His hand slipped under the waistband of my pants, his fingers brushing the sensitive skin just above my hip. The sigil flared, a wave of heat crashing through me so intense I cried out. “You’re mine.”

“I’m not—”

“You are.” He kissed me again, deep, desperate, feeding the bond, feeding the fire, feeding the truth I’d been running from. “Say it.”

“I can’t—”

“Say it.” His fingers slipped under the waistband—just an inch, just enough to make me gasp, to make my back arch, to make my thighs clench. “Say you’re mine.”

My breath came faster. My skin burned. The bond screamed, a raw, primal thing that clawed at my insides, demanding him.

And then—

I said it.

Not because I had to.

Not because of magic.

Not because of duty.

Because I wanted to.

“I’m yours,” I whispered, my voice breaking. “Always.”

He didn’t smile. Just pulled me closer, his mouth claiming mine, his body pressing me against the wall, the bond flaring gold and bright around us like a vow.

And for the first time, I didn’t fight it.

I leaned into it.

Into him.

Into the truth.

That I wasn’t here to destroy the man who let my mother die.

I was here to find the man who’d loved her.

And the man who loved me.

When I finally pulled away, breathless, trembling, my forehead resting against his, I whispered the only truth I had left.

“I don’t know if I can do this.”

“You don’t have to,” he said. “Just stay.”

And I did.

Because for the first time, I wasn’t sure I wanted to leave.

Because for the first time, I wasn’t sure I could.

Because for the first time, I wasn’t sure I wanted to.

He stood, pulling me up with him, his hand finding mine. “We have to go,” he said. “The guards will be here soon.”

“And the High Queen?” I asked.

“She’ll come,” he said. “But not yet. Not until she’s sure.”

“Sure of what?”

“That I’ve broken my oath.” He looked at me, his silver eyes dark. “That I’ve chosen you over the law. Over the Council. Over everything.”

My breath caught.

“And have you?” I asked.

He didn’t answer. Just pulled me into his arms, his mouth finding mine, his hands tangling in my hair, holding me like he’d never let go.

And the bond—

The bond flared, gold and bright, wrapping around us like a promise.

And for the first time, I didn’t fight it.

I leaned into it.

Into him.

Into the truth.

That I wasn’t here to destroy the man who let my mother die.

I was here to find the man who’d loved her.

And the man who loved me.
