BackMarked Harmony: Blood & Bond

Chapter 37 – Sacrifice Offered

CASSIAN

The silence after Thorne’s fall is not peace.

It’s the breath before the storm. The stillness before the reckoning. The quiet that follows a scream too long held back. The courtyard is in ruins—stone cracked, sigils shattered, revenants crumbled to ash—but the air still hums with the echo of magic, of blood, of a curse that refuses to die. It coils beneath my skin, not in pain, not in fury, but in hunger. A slow, deep ache in my chest, like something ancient is stirring, something that remembers the moon, the blood, the vow that was never meant to be broken.

And Harmony—

She’s bleeding.

Not badly. Not mortally. Just a wound—a shallow cut from her own cursed dagger, now turned against her by the man who wanted to break us. But it’s not the blood that terrifies me.

It’s the way she’s standing. Straight. Still. Unbroken. Like she doesn’t feel it. Like she’s already given herself to the fire and walked out the other side.

“You’re hurt,” I growl, stepping toward her, my fangs bared, my hands flying to her shoulder. The fabric of her dress is torn, the skin beneath pale, the wound already sealing, but the sigils along her arms flare—white fire racing beneath her skin—as if the curse is feeding on it. As if it’s awake.

She doesn’t flinch.

Just looks at me—really looks—with those storm-gray eyes that have seen too much, felt too much, fought too hard. “It’s nothing,” she says, her voice steady, rough. “Just a scratch.”

“Don’t lie to me,” I snap, pressing my mouth to the wound, my tongue dragging over the cut, my magic surging. The sigils flare brighter, and she gasps, her fingers tangling in my hair, her body arching into me. The bond screams—not in pain, not in magic, but in recognition. Like it knows. Like it remembers. Like it accepts.

But it’s not enough.

Nothing is ever enough.

“You took the blow for me,” I say, pulling back, my gold eyes burning into hers. “You didn’t have to—”

“Yes, I did,” she interrupts, rising on her toes, her lips brushing mine. “Because you’re mine. And I’ll burn the world before I let anyone take you from me.”

My chest tightens.

Because she means it.

Not as a vow. Not as a threat.

But as a truth.

And that’s what terrifies me.

Not the revenants. Not Thorne. Not the curse.

It’s the way she looks at me—like I’m worth dying for. Like I’m worth living for. Like I’m not just a prince forged in war, a weapon wrapped in silk and shadow, but something more.

And I don’t know how to be that man.

Not yet.

We return to the chambers in silence.

Not tense. Not fragile. But full. The bond hums between us—steady, strong, ours—but beneath it, something darker stirs. The curse. Not broken. Not gone. But waiting. Like it knows what’s coming. Like it’s been waiting for centuries.

Harmony walks beside me, her hand in mine, her breath steady, but I feel it—beneath the calm, beneath the strength, beneath the queen she has become—fear. Not for herself. Not for the throne. But for me.

And I know why.

Because I know what the curse demands.

One life to awaken the other.

And if it’s not her—

—it’s me.

“You’re thinking,” she says, stepping into the chamber, her storm-gray eyes locking onto mine. “Again.”

“I’m calculating,” I correct, closing the door behind us, the lock clicking into place. “We stopped Thorne. We broke Vael. We sealed the bond. But the curse isn’t gone. It’s just… balanced. And balance is fragile.”

She doesn’t answer.

Just walks to the window, her boots silent on the obsidian floor, her gaze fixed on the horizon, where the first light of dawn bleeds through the mist. The sigils on her arms glow faintly, reacting to the bond, to the curse, to the truth that has no mercy.

“Then we make it unbreakable,” she says, her voice low, steady.

“How?” I ask, though I already know.

She turns to me—really turns—and for the first time, I see it.

Not fear.

Not doubt.

But resolve.

“The ritual,” she says. “The final sacrifice. One life to awaken the other. But what if it’s not a sacrifice? What if it’s a choice?”

My jaw tightens.

Because I see it now.

The truth.

The lie.

“You think we can both survive it,” I say, stepping toward her, my voice low, rough. “You think love makes us strong enough to break the cycle.”

“I don’t think,” she says, stepping into me, her hands on my chest, her storm-gray eyes blazing. “I know. Because we’re not just bound by magic. We’re bound by choice. By truth. By love. And if the curse wants a life—” She stops, her breath catching. “—then it can have both.”

My chest tightens.

Because she’s not just saying it.

She’s offering it.

Her life. Her blood. Her legacy.

For me.

“No,” I say, my hands flying to her waist, pulling her against me. “I won’t let you die for me. Not now. Not ever.”

“And I won’t let you die for me,” she says, rising on her toes, her lips brushing mine. “So we do it together. We break the curse. We end it. Once and for all.”

My fangs drop.

Not in hunger.

Not in threat.

But in pride.

Because she’s not just my mate.

She’s my equal.

She’s my queen.

And she’s ready to burn the world with me.

The ritual chamber is deep beneath the Obsidian Court, hidden beneath layers of wards and blood oaths, its walls lined with black stone, its floor etched with ancient runes that pulse like a heartbeat. The air is thick with the scent of cedar and frost, the tang of old magic and iron, the electric hum of the bond syncing with the pulse of the curse. A single altar stands at the center—carved from obsidian, its surface stained with centuries of blood.

Harmony walks beside me, her hand in mine, her breath steady, but I feel it—beneath the calm, beneath the strength, beneath the queen she has become—fear. Not for herself. Not for the throne. But for me.

And I know why.

Because I know what this place is.

Not just a chamber.

Not just a temple.

But a grave.

“This is where it began,” she says, stepping forward, her fingers brushing the altar. The sigils flare—white fire racing across her skin—and she gasps, her breath catching as the magic screams in her veins. “Where Elspeth bound the D’Vaire heir. Where the curse was forged. Where the lie began.”

“And where it ends,” I say, stepping beside her, my coat open, my fangs bared. “With us.”

She turns to me—really turns—and for the first time, I see it.

Not just strength.

Not just fire.

But grief.

Because she knows—

She knows the full moon is rising.

She knows the curse demands a sacrifice.

And she knows—

—if it’s not me…

—it’s her.

“You don’t have to do this alone,” I say, pulling her close, my breath warm against her neck.

“I’m not alone,” she says, pressing her palm to my chest, where my heart beats—strong, steady, hers. “I have you.”

“Then let me go first,” I say, my voice low, rough. “Let me take the blow. Let me be the one who—”

“No,” she says, stepping back, her storm-gray eyes blazing. “If someone has to die—” She stops, her breath catching. “—it’s me.”

My jaw tightens.

“You don’t get to choose for me,” I growl, stepping into her, my body caging hers, my gold eyes burning. “Not when it comes to this. Not when it comes to us.”

“Then we don’t choose,” she says, her fingers tangling in my hair. “We do it together.”

And then—

—she does it.

She presses her palm to my chest, her magic surging, her voice chanting in Old Tongue. The sigils flare—white fire racing across the stone, spiraling up her arms, across her collarbones, down her spine. The bond screams—not in pain, not in magic, but in recognition. Like it knows. Like it remembers. Like it accepts.

“*By blood and breath, I bind my soul to yours,*” she whispers, her storm-gray eyes locking onto mine. “*Not for power. Not for legacy. But for love. For truth. For eternity.*”

My chest tightens.

Because I do.

Not for the bond.

Not for the curse.

But for her.

“*By blood and fang,*” I say, voice low, rough, “*I bind my soul to yours. Not for power. Not for legacy. But for love. For truth. For eternity.*”

The sigils flare—brighter, hotter—white fire racing through our veins, painting the chamber in silver light. The ground trembles. The air shivers. And then—

—the ritual begins.

The altar splits—stone cracking, runes flaring—as a pool of black liquid rises from within, swirling like ink in water. The scent of old magic and iron fills the air, thick and cloying, and the curse screams—not in anger, not in power, but in recognition. It knows. It sees. It accepts.

“One life to awaken the other,” Harmony says, stepping toward the pool. “But we’re not giving one. We’re giving both.”

My chest tightens.

Because she’s right.

The curse wasn’t cast to destroy.

It was cast to find.

To find the ones who would choose each other. Who would fight for each other. Who would die for each other.

And we are those ones.

“Then we break it,” I say, stepping beside her, my hand finding hers. “Together.”

And then—

—we do it.

We step into the pool—side by side, hand in hand—and the black liquid rises, swallowing us, cold and thick, like blood. The sigils flare—white fire racing through our veins—and the curse screams, not in pain, not in fury, but in release. The ground trembles. The air shivers. And then—

—the world goes white.

Not with light.

Not with fire.

But with truth.

I see it—

Not just the past.

Not just the blood.

But the future.

Us.

Together.

And then—

—I feel it.

The pull.

The truth.

The blood.

It wants to obey.

It wants to submit.

“No,” I gasp, clutching Harmony’s hand, my fangs baring. “We don’t submit. We choose.”

She doesn’t answer.

Just presses her lips to mine—soft, slow, deliberate—not in passion, not in hunger, but in truth. Not a claiming. Not a vow. But a union. Her breath flows into me—warm, steady, hers—and I take it, swallowing it like a prayer, like a promise, like a life.

The bond screams—white fire racing through our veins, sigils flaring so bright they light up the chamber, the air shivering with power.

And then—

—I return it.

My breath flows into her—cool, steady, mine—and she takes it, her body arching, her magic flaring beneath her skin. The sigils on her arms glow violet and silver, spiraling up her neck, across her face, down her chest. The ground trembles. The air shivers. And then—

—it’s done.

The black liquid recedes. The runes fade. The altar seals.

And we rise—breathless, trembling, ruined—but alive.

Not in pain.

Not in magic.

But in peace.

The bond hums between us—strong, steady, ours—and for the first time in centuries, I feel it.

Not just love.

Not just desire.

But peace.

“It’s over,” Harmony whispers, her storm-gray eyes blazing. “The curse is broken.”

“No,” I say, cupping her face, my thumb brushing her cheek. “It’s not broken. It’s balanced. And we’re the ones who hold the scale.”

She doesn’t answer.

Just leans in, her lips brushing mine, her breath warm against my mouth. The bond hums—no longer screaming, no longer burning, but harmonizing—white fire racing through our veins, sigils flaring in unison, a storm of light and blood and truth.

When we finally pull apart, our breaths are ragged, our lips swollen, our eyes locked.

“Now,” she says, rising on her toes, pressing her lips to mine. “We take the throne.”

And as we stand there, in the quiet, in the dark, in the truth—

—I know.

This isn’t just survival.

This isn’t just love.

This is reign.

And I’ll burn the world before I let anyone take it from me.
