BackFanged Vow: River’s Claim

Chapter 35 - Rewriting the Oath

RIVER

The morning after Torin’s fire, the Keep was silent—not with tension, not with fear, but with something deeper. A kind of stillness that came only after a storm had passed, leaving behind scorched earth and fragile hope. The wind swept through the broken windows of the east tower, carrying with it the scent of ash, salt, and something softer—blackthorn blossoms, scattered like snow across the stone where Torin had burned.

I stood at the edge of that tower, arms wrapped around myself, my boots crunching on the silver-gray remnants of flame. My body ached—wrists raw from the chains, ribs bruised from Malrik’s grip, soul fractured from the weight of what we’d lost. But I was alive. And so was he.

Kaelen.

He stood a few paces behind me, coat unbuttoned, sleeves rolled to his forearms, fangs just visible in the low light. He hadn’t spoken since we’d returned. Hadn’t touched me. Hadn’t even looked at me—not directly. But I felt him. The bond pulsed between us, low and steady, like a heartbeat beneath my skin. Not screaming. Not burning. Just… present. Alive. Ours.

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

“You’re thinking,” he said, voice rough, breaking the silence.

I didn’t turn. “I’m remembering.”

“Of him?”

“Of all of it.” I finally looked at him. His face was streaked with ash, his eyes shadowed, his hands still blistered from tearing the silver chains. But he stood tall. Unbroken. “He died for us.”

“And we’ll live for him.”

“No.” I stepped toward him, my voice low, steady. “We’ll *fight* for him. For my mother. For every witch, werewolf, and Fae who’s been enslaved by this Oath.”

His breath caught. “And what do you plan to do?”

“Rewrite it.” I reached into the leather pouch hidden beneath my tunic and pulled out the blackthorn flower—dark petals edged with silver, still soft despite the fire, still warm with memory. “This is the key.”

He didn’t flinch. Just stared at it, those crimson eyes dark with something I couldn’t name. “You’re sure?”

“I’m sure.” I stepped closer, close enough to feel the heat of him, the rise and fall of his chest, the low growl in his throat. “My mother didn’t want to destroy the Oath. She wanted to *change* it. To make it fair. To free the bloodlines without killing the king.”

“And you think you can?”

“I know I can.” I pressed the flower into his palm, my fingers brushing his burned skin. He didn’t pull away. Just closed his hand around it, slow, deliberate. “But I need access to the Bloodstone Chamber. I need the original runes. I need time.”

“And protection,” he said.

“While I work, you draw out the Council. Make them think the bond is breaking. Make them think you’re turning to Lyra.”

His fangs bared. “You want me to *pretend* to choose her?”

“Just enough,” I said. “Just enough to make them believe it. Just enough to make them move.”

The bond flared—hot, sharp, *painful*.

But he didn’t flinch.

Because he knew—

This wasn’t betrayal.

This was strategy.

This was *trust*.

And if he trusted me with this—

Then I’d trust him with everything.

“And when they come for you?” he asked.

“That’s when we strike,” I said. “You intercept them. I rewrite the Oath. And when it’s done—” my voice dropped to a whisper—“we burn their lies to the ground.”

He stared at me.

This vampire king. This predator. This *killer*.

And for the first time since I’d walked into Blackthorn Keep, I didn’t see a monster.

I saw a man.

And that terrified me more than any blade, any oath, any lie ever could.

“You’re brilliant,” he said, voice rough.

I didn’t smile. Didn’t smirk. Just looked at him, those dark eyes seeing too much. “And you’re learning to listen.”

His breath caught.

Because he was right.

He *was* learning.

Not to command.

Not to control.

But to *follow*.

For once.

For me.

He stepped closer, slow, and brushed his hand over mine—just once. A jolt of sensation shot through me, sharp and sweet. The bond flared. My breath hitched.

“Then let’s do it,” he said. “Let’s end this.”

I didn’t pull away. Just stayed where I was, my fingers trembling beneath his. “You’re not going to try to stop me?”

“No.”

“You’re not going to claim me in the Bloodstone Chamber? To mark me as yours?”

“Not unless you ask me to,” he said. “This isn’t about ownership. It’s about freedom. Yours. Mine. Ours.”

My breath caught.

And the bond—

It pulsed, steady, strong.

Like a heartbeat not my own.

Like a promise.

Like a vow.

I lifted my hand, slow, and brushed my fingers over his cheek. Just once. Just enough.

“Then let’s go,” I said. “Before they realize we’re already one step ahead.”

He nodded.

And for the first time since I’d walked into Blackthorn Keep with a blade in my boot and murder in her heart, I didn’t feel like a weapon.

I felt like a queen.

We moved through the Keep in silence, boots soft on the stone, shadows curling around us like a second skin. The halls were quiet—no guards, no attendants, just the occasional flicker of torchlight, the distant echo of footsteps. The storm had passed. The repairs were still underway—cracks in the walls, pools of shadow-water on the floor, the occasional groan of settling stone. But it was holding. Like us.

The Bloodstone Chamber was sealed—iron doors etched with ancient runes, glowing faintly with residual magic. Kaelen placed his palm against the center, blood welling from a cut on his thumb, and the doors groaned open, revealing the chamber within.

Dark stone. Floating candles. A massive obsidian altar at the center, its surface carved with the original runes of the Duskbane Oath—twisting, serpentine symbols that pulsed with crimson light. The air was thick with the scent of old blood, ancient magic, and something sharper—power.

And beneath it all—

Fear.

I stepped inside, boots clicking on the stone. The sigil on my hip flared—low, warm, not burning. Not accusing. Just… there. Like it knew. Like it had seen everything.

“You don’t have to do this alone,” Kaelen said, voice low.

“I do.” I turned to him, my gaze steady. “This is my mother’s work. My bloodline’s legacy. I have to finish it.”

He didn’t argue. Just nodded. “I’ll be outside. Guarding. Waiting.”

“And if the Council comes?”

“They’ll answer to me.”

I almost smiled. “You’re not what I expected.”

“Neither are you.”

And then he was gone, the doors closing behind him with a soft, final click.

I was alone.

With the Oath.

With my mother’s ghost.

With my future.

I stepped to the altar, running my fingers over the runes. They burned beneath my touch—cold fire, ancient pain. I could feel the weight of them, the centuries of servitude, the lives lost, the blood spilled. And at the center—

The binding clause.

By blood and moon, by fang and claw, the witch-blood shall serve the vampire throne, body and soul, until death or the breaking of the bond.

And beneath it—

The seal.

A crescent moon wrapped in thorns—the same sigil that pulsed beneath my skin, the same mark that bound me to Kaelen.

I closed my eyes.

And I remembered.

My mother’s voice, soft but fierce. “The Oath isn’t unbreakable, River. It’s just… twisted. Corrupted. But magic can be rewritten. Contracts can be remade. And if you’re strong enough, brave enough, you can change it.”

I opened my eyes.

And I began.

I pulled out the silver pin etched with the sigil of disruption, pressing it to the center of the binding clause. The metal hissed, the rune flaring crimson. I didn’t flinch. Just pressed harder, letting the pin carve into the stone, breaking the old magic, severing the chain.

Then I took the vial of dried moonlight, uncorking it with trembling fingers. I poured it over the broken rune, the liquid glowing silver, spreading like ink through blood. The chamber hummed, the candles flickering, the air thickening with power.

And then—

The blackthorn flower.

I placed it at the center of the altar, petals soft against the stone. “For you, Mother,” I whispered. “For Torin. For all of us.”

I pressed my palm to the flower, blood welling from a cut on my thumb, and began to chant—the old words, the true words, the words my mother had taught me in secret, by firelight, in the hidden groves of the Pacific Northwest.

By blood not bound, by moon not chained,
By heart not broken, by love not feigned,
I break the lie, I sever the chain,
And write anew what was stained.

The chamber erupted.

Light—white, blinding—exploded from the altar, surging through the runes, cracking the old magic, rewriting the Oath. The candles flared. The stone trembled. The air screamed with power.

And the bond—

It *shattered*.

Not in pain.

Not in loss.

In *transformation*.

I gasped, doubling over, my vision blurring, my breath catching. The sigil on my hip burned—white-hot, searing—but not with accusation. With *recognition*. With *release*.

And then—

It was done.

The light faded. The chamber stilled. The runes glowed—no longer crimson, but silver, their lines clean, their meaning changed.

I stepped back, trembling, my breath coming in shallow gasps. I looked at the altar.

The new Oath.

By blood and moon, by fang and claw,
The witch-blood shall stand as equal, not slave,
Bound by choice, not by force,
And free to love, to live, to be.

And beneath it—

The seal.

Still a crescent moon wrapped in thorns.

But now—

It was *ours*.

Not his.

Not mine.

*Ours.*

The doors groaned open.

Kaelen stood there, coat unbuttoned, fangs bared, eyes wide. He didn’t speak. Just stepped forward, slow, deliberate, and looked at the altar.

And then—

He looked at me.

“You did it,” he said, voice raw.

“We did it,” I said.

He didn’t smile. Didn’t smirk. Just stepped closer, until our bodies were nearly touching. His hand moved to my hip, over the sigil, pressing down, firm, unrelenting. The mark flared—hot, sharp—but it didn’t burn. Not really. It just… shifted. Like it knew.

Like it *recognized* him.

“Then let me show you,” he murmured, voice low. “Let me show you what it means to be mine.”

My breath caught.

And then—

I kissed him.

Not soft. Not slow.

Hard. Desperate. A clash of teeth and tongue and breath, a surge of heat so intense it stole my breath. My hands tangled in his hair, pulling him closer, my body arching into his, my core clenching, already slick, already *ready*.

He groaned, low and deep, his fangs grazing my lip. “Gods, you taste like *mine*.”

And then—

The world shifted.

The wind stilled. The sea calmed. The bond—

It *screamed*.

Not pain.

Pleasure.

A wave of energy so intense it tore through me, white-hot, electric, crashing through my veins, pooling between my legs, making me *climax*—right there, in his arms, in the Bloodstone Chamber, with the new Oath glowing between us.

I cried out, my body arching, my fingers digging into his shoulders.

He held me, groaning, his breath hot against my skin. “That’s it,” he murmured. “Let go. Let me have you.”

And I did.

Not because of the bond.

Not because of the magic.

But because, for one terrible, shameful moment, I *wanted* it.

Wanted him.

Needed him.

And when it was over, when the wind returned, when the sea roared, when the bond settled into a quiet, insistent hum—

I was still in his arms.

Still breathing hard.

Still *his*.

He pulled back, just enough to look at me. His eyes were dark, his lips swollen, his breath uneven. “Better?” he asked, voice rough.

I didn’t answer. Just stared at him, those dark eyes seeing too much. “You’re not what I expected,” I said.

“Neither are you.”

He smiled—slow, dangerous. “Now imagine what it’ll be like when I’m *inside* you.”

My breath caught.

And the bond—

It *screamed* again.

I didn’t push him away.

Didn’t walk out.

Just stayed in his arms, my body still trembling, my breath still unsteady.

And when he leaned in, when his lips hovered over mine, when his breath ghosted over my skin—

I didn’t say yes.

But my body arched into his.

And for the first time since I’d walked into Blackthorn Keep, I didn’t feel like a prisoner.

I felt like a woman.

And that terrified me more than any blade, any oath, any lie ever could.

Because if he wasn’t the monster I’d believed him to be—

Then what did that make me?

What did that make *us*?

I didn’t have an answer.

Not yet.

But as I stood there, his arms still around me, his breath warm against my neck, I had to admit one terrible, shameful truth:

I didn’t want him to let go.

And when I finally lifted my head, when I met his eyes in the dim light, when I saw the hunger still there—barely restrained, barely contained—I didn’t look away.

Because part of me—shameful, traitorous, hungry—wanted to say yes.

Wanted to arch into him.

Wanted to beg.

But I didn’t.

Because if I gave in—if I let him touch me, let the bond pull me under—I wouldn’t just lose my mission.

I’d lose myself.

And then, there’d be nothing left to save.

So I stayed still.

Stayed silent.

And when he finally leaned in, when his lips hovered over mine, when his breath ghosted over my skin—

I didn’t say yes.

But my body arched into his.

And then—

I pulled back.

Just enough.

And I looked at him.

Really looked.

Not at the king. Not at the predator. Not at the monster.

At the man.

The one who had held me through the worst of it. Who had denied his nature. Who had let me break him. Who had burned his brother to ash with his own blood.

And I knew—

This wasn’t about revenge.

Not anymore.

It was about justice.

For my mother.

For Torin.

For all of us.

“We fight them together,” I said, voice steady.

He didn’t smile. Didn’t smirk. Just nodded. “As equals.”

And the bond—

It pulsed, steady, strong.

Like a heartbeat not my own.

Like a promise.

Like a vow.

And for the first time since I’d walked into Blackthorn Keep, I didn’t feel like a weapon.

I felt like a queen.
