BackBirch’s Claim: Blood and Thorn

Chapter 36 – Heartroot’s Choice

CASSIAN

The first rule of power is this: never let them see you bleed.

And yet, I’m bleeding.

Not from a wound. Not from a blade. But from the silence—the hollow, suffocating absence of her voice, her scent, her presence. For three days, I’ve walked the halls of the Winter Court like a ghost, my storm-gray eyes scanning every shadow, every whisper, every flicker of magic, searching for a sign. But there is none. No message. No trace. No pulse of the bond.

She’s gone.

And I know—without proof, without magic—that Silas has her.

I felt it the moment she vanished. A scream in the dark, not in sound, but in soul. A rupture in the bond, not a severing, but a suppression. Like a light smothered, not extinguished. And I did nothing. I stayed. I waited. I let her go, thinking I was protecting her, thinking I was giving her a chance to live.

And I was wrong.

So wrong.

The guilt coils in my gut like a serpent, cold and patient, tightening with every breath I take. It doesn’t scream. Doesn’t rage. It just is, a constant hum beneath the surface, a shadow I can’t outrun. I should have known. Should have felt it. The bond may be buried, but it’s not dead. And neither is she.

And I will burn the world before I let her die alone.

I find Kael in the war room, his amber eyes sharp, his hands clenched around a dagger etched with thorned sigils. The obsidian table is covered in maps of the Wilds, sigils etched into stone, troop movements marked in blood-red ink. But he’s not looking at the maps.

He’s staring at the scrying pool.

Its surface ripples, not with water, but with smoke and shadow, forming an image—Birch. Bound. Collared. Her storm-gray eyes wide with pain, her lips moving, whispering something I can’t hear. And beside her—Silas. Smiling. Cold. Calculating.

“She’s alive,” Kael says, voice low.

“Where?”

“Abandoned subway tunnels beneath Prague. Old ISO black site. Warded. Heavily guarded. Hybrid soldiers, blood-bound to him.”

I don’t hesitate. “Then we go.”

“You can’t go alone.”

“I’m not.” I turn to the door, my voice cutting through the silence. “Kaelen. Mira. Assemble the rebels. We move in one hour.”

He doesn’t argue. Just nods, his amber eyes burning with something I haven’t seen in years—loyalty. Not to a king. Not to a title. To her.

Because she made him see.

She made them all see.

And now, I’ll make Silas see what happens when you take something that’s mine.

The tunnels are worse than I imagined.

Not just the stench—antiseptic, iron, decay—but the silence. Not the absence of sound, but the wrongness of it. Like the world has been hollowed out, stripped of life, of magic, of breath. The walls are lined with sigils that pulse faintly with dark energy, feeding on stolen power, on pain, on fear. The air is thick with it—wrongness—like poison in the veins.

We move fast—Kael ahead, silent, watchful, his amber eyes scanning for traps. Mira brings up the rear, her breath ragged, her hands trembling, but her magic steady. Behind us—twenty rebels, half-wolf, half-fae, half-witch—each one bearing a thorned sigil on their palm, each one loyal to her.

And I? I’m not their king tonight.

I’m her hunter.

Her avenger.

Her mate.

The bond hums beneath my skin—warm, restless, alive. It doesn’t hurt. Not anymore. It just is. A presence. A truth. And for the first time, I don’t fight it. I let it guide me, a live wire sparking under my skin, pulsing in time with hers. Her magic answers mine, a low, steady thrum beneath my ribs, like a second heartbeat keeping time with hers.

And then—

We hear it.

A scream.

Not from pain.

From rage.

And I know—without seeing, without proof—that it’s her.

The lab is a cavern of concrete and steel, its walls lined with vials of dark liquid, syringes, and something that looks like a thorned circlet made of black iron. The Thorn Pact—reforged, perverted, weaponized. And in the center—

Birch.

On her knees.

Her shadow-leather torn, her skin pale, her storm-gray eyes blazing with fire even as her body trembles with exhaustion. A collar—black iron etched with sigils that pulse faintly—clamps around her throat, humming with anti-magic. Her wrists are bound, her ankles locked in place. And standing over her—

Silas.

His sharp suit pristine, his cold eyes gleaming, his smile like a scalpel. He holds a syringe filled with dark liquid—her blood, I realize. Thick, pulsing, laced with thorned veins.

“You’re too late,” he says, not turning. “The extraction is complete. The bond is broken. And she—” He glances at her. “—will be obedient. Powerful. Mine.”

“No.” My voice cuts through the chamber like ice. “She was never yours to take.”

He spins, his eyes wide with shock. “You’re not supposed to be here!”

“I’m always where I’m needed.” I raise my hand—ice spiraling from my palm, sharp as blades, slicing through the vials, the syringes, the tray. The liquid spills, hissing as it hits the floor. The rebels move—fast, silent, lethal—taking down the guards, the hybrids, the scientists. Kael disarms two with a single sweep, his claws bared. Mira chants a sigil, and the walls crack, the wards shattering like glass.

And I? I move toward her.

But Silas is faster.

He grabs her by the hair, yanks her head back, presses a knife to her throat. “One step closer, and I’ll slit her throat.”

My breath stills.

But I don’t stop.

“You think I care?” I say, stepping forward, ice spiraling from my palms, wrapping around his legs, his arms, his neck. “You think I won’t burn the world to save her?”

“You will,” he says, not flinching. “But not before I take everything from you.”

And then—

He presses a button on the wall.

The lights dim. The air shifts. The sigils on the walls pulse, brighter now, deeper, alive. And then—

A figure steps from the shadows.

Not a guard.

Not a hybrid.

Me.

My breath stills.

He’s dressed in black leather, my silver hair slicked back, my storm-gray eyes sharp, cold, empty. No warmth. No fire. No me. Just a mask. A puppet.

“Impossible,” I whisper.

“Oh, but it is,” Silas says, smiling. “A glamour, of course. But not just any glamour. A perfect one. Crafted from her memories. Her desires. Her love.”

The figure steps forward, slow, deliberate. “Cassian,” he says—my voice, my cadence, my breath hot against her ear. “You left me.”

Her breath hitches.

“I didn’t,” she whispers. “I saved you.”

“Did you?” The figure cups her face, his thumb brushing her cheek. “Or did you just bind me? Control me? Turn me into your weapon?”

“No.” Tears burn in her eyes. “I chose you. I love you.”

“Love is weakness,” the figure says, voice cold. “And you made me weak.”

My chest tightens.

“You’re not him,” she says, voice breaking. “You’re not Cassian.”

“Aren’t I?” The figure leans in, his lips brushing hers. “Then why does your body respond? Why do your thorns bloom? Why does your heart race?”

And it’s true.

Despite everything—despite the cold, the pain, the betrayal—her body responds. Her thorns twitch beneath her skin. Her breath hitches. Her core clenches. The bond—buried, suppressed—flares, a low, desperate pulse beneath the iron collar.

“See?” Silas says, jotting more notes. “The body remembers. The magic remembers. Even when the mind resists.”

“You don’t get to do this,” she whispers, tears falling. “You don’t get to use him. To twist him.”

“Oh, but I do.” Silas smiles. “Because love is not a strength. It’s a flaw. A vulnerability. And I’m going to fix it.”

He lifts the thorned circlet.

Black iron. Thorns shaped like sigils. The Thorn Pact—reforged, perverted, weaponized.

“This will suppress the bond,” he says. “Block the magic. Erase the emotion. And when it’s done—” He smiles. “—you’ll be perfect. Obedient. Powerful. Mine.”

“Never,” she snarls.

But the circlet is already lowering.

Toward her head.

I move.

Not with ice.

Not with magic.

With rage.

My body is a blur—fast, silent, lethal. I slice through the ice binding the figure, shatter the glamour with a single word, and lunge at Silas. He tries to dodge, but I’m faster. My ice wraps around his wrist, freezing the circlet, shattering it. The knife clatters to the floor.

He stumbles back, his eyes wide with shock. “You can’t stop it! The bond is broken! She’s mine!”

“She was never yours,” I growl, ice spiraling from my palms, encasing him from the neck down. “She is mine. And I will burn the world before I let you take her.”

“You already did,” he spits. “You left her. You abandoned her. You—”

“I was wrong.” My voice is rough. “And I will spend the rest of my life making it right.”

And then—

I turn to her.

She’s on her knees, her storm-gray eyes wide, her breath ragged, her body trembling. The collar still hums, pulsing, feeding. I press my marked hand to it—ice spiraling, cracking the sigils, warping the metal. It shatters with a scream, falling to the floor in black shards.

And then—

The bond screams.

Not in pain.

Not in fear.

In awakening.

A pulse—bright, blinding, alive—rips through the lab, throwing us back, shattering the remaining vials, sending the rebels stumbling. The sigils on the walls ignite, burning with cold blue flame. The thorns on the floor come alive, spiraling up, wrapping around our legs, our arms, our throats—but not to bind.

To connect.

We both gasp, our bodies arching, our eyes rolling back. The magic surges—heat, power, destiny—crashing through us like a storm. The thorns on our skin erupt, black vines blooming across our arms, our chests, our necks, feeding on the surge, on the truth.

And then—

A voice.

Not in the air.

Not in the wind.

In our souls.

You are one.

And we are.

Not just bound.

Not just mated.

Fused.

Our magic, our blood, our fire and thorn—intertwined, inseparable, eternal.

The bond flares—warm, steady, right.

And deep beneath the lab, in the vault where the Heartroot’s blood rests, its pulse stirs—stronger now—and for the first time in years, it sings.

Not in fear.

Not in warning.

In approval.

I pull her into my arms.

Not to control. Not to claim.

To hold.

Her face presses into my neck, her scent—fire, thorn, something wild and untamed—wrapping around me, pulling me in. My hands cradle her head, my fingers tangled in her hair. The thorns on her spine erupt, black vines blooming across her skin, wrapping around my arms, feeding on the clash, the heat, the desire.

“You came,” she whispers, her voice breaking.

“Always,” I say, pressing my forehead to hers. “I was wrong. I thought I was protecting you. But I was just running. From you. From us. From the truth.”

“And what’s the truth?”

“That I can’t live without you.” My voice cracks. “That you’re not my weakness. You’re my strength. My fire. My life. And if I have to burn the world to keep you alive—I will.”

She doesn’t speak.

Just kisses me.

Slow. Soft. Deliberate.

Her hands slide up my chest, over the hard planes of my shoulders, into my silver hair. My hands cradle her face, my thumbs brushing her cheeks, my storm-gray eyes burning into hers. The kiss deepens—slow, deep, soul-deep—like she’s pouring everything she’s ever been, everything she’s ever wanted, into this one moment.

And I let her.

Not because I have to.

Not because the bond demands it.

But because I want to.

Because this isn’t just fire.

This isn’t just magic.

This is love.

The kiss breaks, but we don’t pull apart. Our foreheads stay pressed together, our breaths mingling, our hearts pounding in time. The bond hums—warm, steady, right. The thorns on our arms bloom, spreading like ink beneath our skin.

“You don’t get to leave me,” she whispers.

“I don’t want to.” My voice is rough. “But if it’s the price of your survival—”

“Then I won’t pay it.” She grabs my wrists, her grip fierce. “You hear me? I won’t let you die for me. I won’t let the Heartroot take you. I’ll burn it to ash before I let it steal you from me.”

I don’t argue.

Just hold her tighter.

And for the first time since I walked into this court—

I let her.

Not because of the magic.

Not because of the fire.

But because, in her arms, I see it—

Not a monster.

Not a king.

But a man who’s been as lost as I am.

And maybe—

Just maybe—

We’re not meant to burn each other.

Maybe we’re meant to burn the world—

And rebuild it from the ashes.

Together.

Later, in the war room, we stand before the obsidian table, maps of the Wilds spread before us, sigils etched into the stone, troop movements marked in blood-red ink. Kael is at the door, silent, watchful. Mira leans against the wall, her breath still ragged, her eyes sharp with warning.

“They’ll come,” she says. “Nyx. Silas. They won’t let this stand. They’ll strike when we’re weakest.”

“Then we won’t be weak,” I say, not looking up. “We’ll be ready.”

“And if they target the bond?”

“They can’t.” Birch presses a hand to her chest, over the thorned mark on her collarbone. “It’s not just magic anymore. It’s us. And if they try to break it, they’ll break themselves.”

I turn to her, my storm-gray eyes burning. “You’re not just my queen,” I say, voice low. “You’re my fire. And I will not let you burn alone.”

The bond flares—heat rolling through me, sudden and deep. My breath hitches. My core tightens. The thorns on my spine twitch, responding to the surge of magic, of desire.

And then—

I pull her close.

Not to control. Not to claim.

To hold.

Her face presses into my neck, her scent—fire, thorn, something wild and untamed—wrapping around me, pulling me in. My hands cradle her head, my fingers tangled in her hair. The thorns on her spine erupt, black vines blooming across her skin, wrapping around my arms, feeding on the clash, the heat, the desire.

“You don’t get to leave me,” she whispers.

“I don’t want to.” My voice is rough. “But if it’s the price of your survival—”

“Then I won’t pay it.” She grabs my wrists, her grip fierce. “You hear me? I won’t let you die for me. I won’t let the Heartroot take you. I’ll burn it to ash before I let it steal you from me.”

I don’t argue.

Just hold her tighter.

And for the first time since I walked into this court—

I let her.

Not because of the magic.

Not because of the fire.

But because, in her arms, I see it—

Not a monster.

Not a king.

But a woman who’s been as lost as I am.

And maybe—

Just maybe—

We’re not meant to burn each other.

Maybe we’re meant to burn the world—

And rebuild it from the ashes.

Together.

And deep beneath the palace, in the vault where the Heartroot rests, its pulse stirs—stronger now—and for the first time in years, it sings.

Not in fear.

Not in warning.

In preparation.

Queen Nyx, watching from a scrying pool in the Summer Court, smiles.

“Good,” she whispers. “Let them burn for each other.”

“And when they do?” asks a shadowed figure beside her.

“Then we take everything.”

She turns from the pool, her golden eyes glowing with malice.

“The real game has just begun.”
