BackSeraphina’s Claim: Blood & Thorn

Chapter 17 - Rescue in Thorns

CASSIAN

The chamber door slammed shut behind her.

The sound echoed like a death knell.

Not just the heavy thud of enchanted oak and iron reinforcing, not the hiss of sealing runes flaring to life along the frame—but the finality of it. The *end* of something. The beginning of something worse.

They had taken her.

Not just into custody.

Into *darkness*.

The High Inquisitor’s cells were deep beneath the palace, carved from black stone and lined with thorned iron that drank magic and amplified pain. No light. No air. Just silence, cold, and the slow, steady drip of poisoned water from the ceiling. I’d seen what those cells did to prisoners. How they broke them. How they hollowed them out until only obedience remained.

And Seraphina—

She wasn’t just a prisoner.

She was my sister.

My heir.

My blood.

And if I didn’t get her back—

Before the full moon rose—

We would both die.

“You let them take her.”

Kaelen’s voice cut through the silence, low, sharp, accusing.

I didn’t answer. Just stood there, my hand still pressed to the door where I’d last touched her fingers through the bars. The bond had screamed—not in pain, not in need, but in something deeper. Something primal. A cry from one soul to another. And I had felt it. Felt her fear. Her rage. Her refusal to break.

“You stood there,” Kaelen said, stepping forward. “You didn’t fight. You didn’t draw your vines. You didn’t move.”

“I gave her a promise,” I said, my voice rough.

“And what good is a promise if she’s dead?”

I turned to him, my gold eyes blazing. “I promised her we’d break her out. Not that I’d die trying to stop them in the Council Chamber.”

He stared at me. Then exhaled, long and slow. “So what’s the plan?”

I didn’t speak. Just turned and walked toward the archway, my boots echoing against the stone. The thorns on the walls twitched as I passed, their barbs glistening like wet teeth. The air hummed with magic, thick with the scent of sap and decay. And the bond—

It wasn’t fading.

It was feeding.

With every step, I could feel it—the thread between us, thin but unbreakable, thrumming with something deeper than magic. Blood. Truth. History. And beneath it—hunger. Not for food. Not for sleep. But for her. For the heat of her skin, the taste of her breath, the way her body moved like liquid under her clothes.

“You’re going alone,” Kaelen said, falling into step beside me.

“No,” I said. “But you’re not coming.”

“She’s not just your consort,” he said. “She’s the only one who’s ever made you look at someone like you’re not just calculating their usefulness.”

I stopped.

Turned to him.

“You think I don’t know what she is to me?” I asked, voice low. “You think I don’t feel it every time she looks at me? Every time the bond flares? Every time I remember the way she bit me in the Healing Chamber—not in rage, not in pain, but in claiming?”

He didn’t flinch. Just watched me, his golden eyes sharp. “Then go get her.”

“I will,” I said. “But not with an army. Not with noise. Not with fire.”

“Then how?”

“With silence,” I said. “With shadow. With the one thing they’ve forgotten I still have.”

“And what’s that?”

“Mercy,” I said. “And the will to burn it all down if I have to.”

The descent to the prison level was a slow, suffocating crawl.

No torches. No guards. No light but the faint, pulsing glow of the thorns lining the walls—black, glistening, their barbs dripping with dew that smelled of iron and rot. The air was thick, warm—too warm—with the scent of damp bark and something deeper, something primal. My boots made no sound on the stone. My breath was silent. My heart—

It wasn’t steady.

It was a war drum, each beat screaming mine, mine, mine.

I didn’t take the main stair.

Didn’t risk the surveillance sigils or the sentry vines that could alert the entire palace with a single shiver. Instead, I took the old path—the one few knew existed. A hidden passage behind the Archive walls, a tunnel carved by forgotten hands, its entrance sealed with blood and thorn. I pressed my palm to the stone, letting my blood drip onto the ancient runes. They flared—black, then red—before the wall groaned open.

Inside, the air was colder. Stale. The scent of old blood clung to the walls, mixed with the faint, metallic tang of fear. The tunnel sloped downward, narrowing with every step, until I had to crouch, then crawl. My coat snagged on unseen thorns. My skin burned where the barbs scraped me. But I didn’t stop.

Not until I reached the grate.

A small, rusted opening, barely wide enough for a hand. But enough.

I pressed my eye to it.

And saw her.

She was in the farthest cell, the one with no window, no light, just the slow drip of poisoned water from the ceiling. She sat on the stone bench, her back straight, her storm-gray eyes open, unblinking. No illusion. No mask. Just her. My sister. The heir. The storm in human form.

Her gown was torn at the shoulder, her hair loose around her face. But she wasn’t broken. Wasn’t cowering. Just waiting.

And then—

She turned.

Looked right at the grate.

As if she’d felt me.

As if the bond had whispered my name.

Our eyes met.

And the thread between us—

It didn’t flare.

It roared.

Fire. Not metaphor. Fire. It ripped through my veins, molten and electric, surging from the point of contact straight to my core. My breath punched out of me. My knees buckled. I would have fallen if I hadn’t caught myself on the wall.

Heat. So much heat. My skin burned. My blood sang. My pulse roared in my ears, a drumbeat of pure, animal need. Between my thighs—hard. Aching. My cock strained against the fabric of my trousers, desperate to be inside her.

And worse—her. I could feel her. Not just her body in the cell. Her thoughts, her hunger, her cold, controlled rage. A flicker of shock. A surge of something darker—desire, raw and unchecked. It slammed into me like a fist.

She didn’t speak.

Just pressed a hand to the grate, her fingers trembling.

I pressed mine to hers, the metal cold between us.

And the bond—

It screamed.

Not from pain.

Not from need.

But from love.

I didn’t go back the way I came.

Didn’t waste time crawling through the tunnel, didn’t risk the sentry vines or the surveillance sigils. Instead, I did what no one expected.

I called the thorns.

Not the ones on the walls.

Not the ones in the palace.

The ones in the stone.

Deep beneath the foundation, where the roots of the ancient trees twisted through the bedrock, where the oldest magic still pulsed in slow, steady waves. I pressed my palm to the floor, my blood dripping onto the stone, and I called.

Not with words.

Not with magic.

With blood.

And they answered.

Black vines, thick as arms, erupted from the floor, bursting through the stone like serpents. They coiled around me, not to bind, not to punish—but to carry. To lift. To move. I let them take me, let them pull me through the earth, through the walls, through the sealed doors, until I stood in the prison corridor, just outside her cell.

The guards didn’t see me.

Didn’t hear me.

They were too busy watching the sigils on the door, too focused on the enchantments meant to keep her in.

They didn’t expect an attack from below.

I didn’t give them time to react.

The thorns moved like lightning.

One moment, the guards were standing. The next—silence. Vines wrapped around their throats, their chests, their limbs, squeezing until the fight left them. Until the light in their eyes dimmed. Until they were nothing but husks, dissolving into the stone floor like ash in the wind.

I didn’t watch them die.

Just stepped over their bodies and pressed my hand to the cell door.

The runes flared—black, then red—before the lock clicked open.

She didn’t move.

Just sat there, her storm-gray eyes holding mine, her breath trembling.

“You came,” she whispered.

“I promised,” I said.

She stood slowly, her legs unsteady, her body trembling. I stepped forward, reaching for her—

And she slapped me.

Not hard. Not with magic.

But with everything she had.

My head snapped to the side. My lip split. Blood dripped down my chin.

“You let them take me,” she said, voice low, shaking. “You stood there. You didn’t fight. You didn’t move.”

“I gave you a promise,” I said, wiping the blood from my mouth. “And I kept it.”

“You should have fought,” she said. “You should have burned the chamber to the ground.”

“And gotten us both killed?” I asked. “Is that what you want?”

She didn’t answer.

Just pressed a hand to her chest, where the sigil still pulsed.

“The full moon is coming,” she said. “And if we don’t complete the bond—”

“—we die,” I finished. “I know.”

“Then why did you wait?”

“Because I needed to get you out alive,” I said. “Not as a martyr. Not as a corpse. As my sister. As my heir. As mine.”

She looked at me, her storm-gray eyes blazing. “You don’t get to call me that.”

“I do,” I said. “Because you marked me. In the Healing Chamber. With your teeth. With your blood. With your truth.”

She pressed a hand to her mouth, her breath trembling.

And then—

She stepped forward.

And kissed me.

Not soft.

Not gentle.

Brutal.

Her mouth crashed into mine, teeth clashing, tongue demanding. I gasped, and she swallowed the sound, one hand fisting in my hair, the other gripping my wrist, pressing me back against the stone wall. The bond roared, a molten wave crashing through me, pooling between my legs, making me hard for her.

I should have stopped her.

Should have pulled away.

But I didn’t.

I kissed her back.

Hard. Desperate. Hungry.

And when she finally pulled back, her breath ragged, her eyes blazing, I didn’t speak.

Because the truth was written in the fire between us.

In the way our blood knew each other.

In the way our hearts ached for each other.

And in the way, when she looked at me, I finally understood—

This wasn’t just survival.

This was surrender.

We didn’t take the stairs.

Didn’t risk the corridors or the sentry vines. Instead, I called the thorns again.

They erupted from the floor, coiling around us, lifting us, carrying us through the stone, through the walls, through the sealed doors, until we stood in the ruins of the old garden—the place where her mother had been executed, where the silver trees had burned, where the thorns had turned to ash.

It was a place of death.

And we were there to live.

I set her down gently, my hands still on her waist, my breath trembling. The bond pulsed between us, a live wire, feeding on proximity, on breath, on the way our bodies knew each other.

“They’ll come for us,” she said, voice quiet.

“Let them,” I said. “We’re not running anymore.”

She looked at me, her storm-gray eyes holding mine. “And if they catch us?”

“Then we fight,” I said. “Together.”

She nodded.

And for the first time, I believed it.

Not because of the bond.

Not because of the mark.

But because of her.

Because she had fought. She had raged. She had killed for the truth. And now—she was ready to fight for something else.

For us.

The wind stirred the thorns.

And somewhere, deep in the heart of the city, a wolf howled.

The full moon was coming.

And I was no longer sure which of us was the hunter.

And which was the prey.

But I knew one thing.

We would face it—

Together.
