My Sister Stole My Mate And I Let Her (Seraphina) novel Chapter 506

Chapter 506: Chapter 506 ANTICLIMACTIC

SERAPHINA’S POV

The silver light between Kieran and me deepened, threading through us like a living current, not just connecting but synchronizing.

Kieran exhaled against my forehead—a sound half disbelief, half ecstasy. I felt his strength, his awareness, his control—no longer separate from mine in the same absolute way they had been before.

Aligned.

Malachar did not approve of the reforged mate bond.

His response was a pressure so deep and ancient it felt like the underground hall itself had suddenly developed a will of its own and intended to crush us.

And then Catherine moved.

But it wasn’t fully Catherine anymore.

The darkness that had been layered into her form convulsed, as if something inside her had been struck directly through its core.

Her body lurched forward, not of her own will. The movement was too harsh, too unnatural.

Like a puppeteer pulling strings.

When she spoke, I could barely hear her voice. It was deep and rough, something vast and furious pressing through every syllable. 𝒇𝓻𝓮𝓮𝙬𝙚𝒃𝒏𝓸𝙫𝒆𝙡.𝓬𝓸𝒎

“You dare.”

The words hit the chamber like a physical impact.

The blue veins of light embedded in the walls flared violently in response, almost to the point of blinding.

Kieran’s grip on my hand tightened. The bond between us pulsed, and I felt something ripple through it—his awareness touching mine, my instincts touching his, not as overlap but as synchronization.

And for the first time, I understood that the mate bond wasn’t just an emotional connection. It was a channel.

Catherine, not in control of the gesture, lifted her hand.

Darkness condensed at her palm, and the air around it bent inward as if reality was being pulled toward a singular point of annihilation.

I saw the consequence of the strike before it hit.

“Kieran—” I started.

“I know,” he responded.

Then he did something that would not have been possible before this moment.

He called my power out.

The bond opened between us like a sealed chamber unlocking under pressure.

Silver surged from me, but this time it didn’t strain or weaken under the chamber’s suppression.

Kieran’s presence flowed through it like a stabilizing structure, and the oppressive system beneath us faltered.

Catherine—or the conduit she’d become—released the strike.

A blade of darkness and void-pressure aimed directly at my chest, designed to collapse not just my body but the silver resonance inside me entirely.

But this fight was no longer mine alone.

Kieran and I stepped forward at the same moment, and the bond between us flared so intensely that I had to squint against the brightness.

Darkness met silver.

And instead of being overwhelmed, it held.

The entire chamber froze in a state of violent equilibrium, as if reality was unsure which rule to obey.

Catherine’s body jerked again, and a distorted sound tore from her throat.

“Impossible,” the layered voice snarled.

The darkness inside her surged harder, forcing her limbs into motion again, trying to override resistance through brute command.

But the bond had already changed the equation.

“I see it now,” Kieran said, voice low.

Simultaneously, the same understanding snapped into place inside me.

“The fragment,” he continued. “It’s anchoring her. It’s not fully him. It’s a piece of his power.”

A root of influence embedded in Catherine like a parasite.

Catherine’s head tilted almost to the point of snapping.

“You speak as if you understand anything,” the layered voice hissed. “You are nothing but inherited instability.”

Kieran’s grip tightened on my hand, and a flood of calm and certainty washed over me, anchoring me.

He turned to me and nodded once. “We end it now.”

The bond responded before I could even nod.

But it didn’t fully sound like hers, either. It was raw, stripped, frail in a way I didn’t think was possible.

“I held it,” she said weakly, as if even speaking cost her. “I controlled it...”

Her body trembled harder, the motion rippling through her like a system losing coherence at every level at once.

What remained of her was suddenly small. Her body was no longer held together by borrowed divinity, but by sheer refusal to accept collapse.

She looked at me with defiance and hate, but beneath that, I could feel it—the absence of true power. She was mortal. Breakable.

Kieran moved first, a subtle shift forward that I felt more than saw. Not aggression. Something quieter, more final. A decision already made.

He was ready to end it.

And so was I.

There was a tidal wave of things I wanted to say to the woman before me. But none of them was quite enough.

None could quite quantify the impact she’d had on my life since I was six years old.

Despite how long it had taken, how hard I’d fought, how much power I’d expended, this moment still felt...anticlimactic.

This was a woman who ruined my life, who terrorized, hurt, and killed countless people. She deserved suffering and pain that matched what she’d put out into the world.

But I didn’t have it in me to take this any further.

Honestly, I was just ready to be done with it and put this whole thing behind me.

Silver power condensed at my fingertips, gathering into form with a finality that felt inevitable, as if it had been waiting for this exact moment to resolve itself into action.

This was finally going to end.

My arm moved forward, and the power surged outward—

“No!”

A voice cut through the chamber like a blade through still water.

The silver light halted mid-air.

It didn’t disperse. It didn’t collapse. It simply...stopped, suspended between intent and execution, held by a force that didn’t feel like Catherine’s or Malachar’s.

Then someone rushed in through the fractured edge of the chamber, past collapsing runes and dying siphon light.

And put her body between mine and Catherine’s
