My Sister Stole My Mate And I Let Her (Seraphina) novel Chapter 504

Chapter 504: Chapter 504 FULL ACCESS

SERAPHINA’S POV

In hindsight, it probably wasn’t a good idea to tease a psychotic lunatic backed by an unknown, powerful force.

Malachar, whoever he was, was more than willing to grant Catherine full access.

The blue veins of light embedded in the walls flared brighter, then steadier, like arteries hit by a stronger pulse. The ritual structure beneath us—carved stone, blackened metal, and sigils—began to hum in response.

And Catherine...

The difference was immediate.

The oppressive presence that bled into the room no longer felt like something she was invoking.

It felt like something she was wearing—no, not wearing, hosting.

The air around her darkened in a way that had nothing to do with light. It was as if the concept of shadow itself had gathered around her form and melded with it.

I recognized it instantly.

That same suffocating pressure from the void. That same invasive awareness that had spoken into my mind, offering me itself or death.

My stomach tightened.

So it wasn’t just that she served him.

She was now an extension of him.

Catherine lifted her head slowly, and the eyes that met mine weren’t hers.

They’d gone entirely black, and there was something layered behind them—hungry and deadly, like a predator looking through a window.

“You feel it, don’t you?” she said softly.

Her voice was still Catherine’s, but flattened at the edges, like it had been pressed through something too large for it to carry fully.

The darkness around her thickened, coiling through the chamber like living smoke.

I forced myself to stand straighter, even as the pressure in the room pressed against my skin and consciousness.

The power inside me stirred in response, but it was...sluggish now, as if something was interfering with my access to it.

Maybe I had used more than I knew to escape the dreamscape I had been trapped in. Maybe this new enemy was affecting it more than I realized.

Either way, my power felt dampened, as if I were no longer entitled to it in full.

Catherine noticed my struggle immediately, her eyes lighting with triumphant amusement.

“Oh,” she murmured, taking a step forward. “This is interesting.”

Another step.

“Performance issues?” she taunted.

I forced a grim smile. “Touché.”

I could feel it more clearly each second: the formation beneath us wasn’t just a structure. It was a system—a living network of siphoning conduits.

It was feeding Catherine and starving everything else.

Including me.

Catherine tilted her head, eyes glittering with delight as she watched me, clearly savoring the realization unfolding on my face.

"I bet you felt pretty special when you anchored to the moon, huh?" Catherine drawled, her voice softening into something indulgent.

“But you know something about the moon?” Her smile widened. “No matter how much power it boasts of, the light it shines is a reflection. Something borrowed. And borrowed things are never permanent.”

I scoffed. “You’re one to talk.”

She barked a short laugh. “Do you know what I find amusing about you, Sera?”

I didn’t answer, but she didn’t seem to need one.

“You think your resistance makes you different,” she continued. “You think struggling against the shape of your life makes you special.”

The darkness behind her shifted again, as if it were listening through her and agreeing.

“But all you’ve done is choose the worst possible version of yourself even when I offered you something better.”

My hands clenched into fists as I bristled at her words, the memory of the life she’d woven for me in the dream flashing in my mind.

“You never offered me anything,” I shot back. “You tried to reframe my reality. You fed me a lie gently wrapped around a chain.”

“And wasn’t it a beautiful life?" Catherine asked. "You had everything you could have ever wanted. You could have spent the rest of your life happy if you just stayed put.”

“No thanks.” I shook my head. "You wouldn’t know true happiness if it bitch slapped you in the face.”

She considered my words for a moment, then shrugged. "I’ve always found the pursuit of happiness a foolish endeavor anyway. Much more fruitful to gather power.”

Then she moved without warning.

She crossed the space between us in an instant, and the first strike landed before I could brace for it.

I staggered backward as pain lanced through my chest, sharp and disorienting, as if something inside me had been grabbed and twisted out of alignment.

Catherine watched me stumble, her expression calm again, satisfied.

“I told you,” she said. “The moon only borrows light.”

She raised her hand, and the darkness around her coiled tighter.

“And the dark swallows everything.”

She struck again.

I barely managed to block it this time, forcing my silver energy outward in a defensive surge.

The collision sent a shockwave through the chamber, rippling across the ritual markings on the floor.

For a moment, I saw the system clearly.
