[Evelyn's POV]
Cassandra lunges and I don't draw a blade.
I pivot, channeling moonlight into a barrier that deflects her strike — not blocks it, not meets it with force, just redirects the killing edge past my shoulder by inches. She recovers faster than I expected, spinning into a second attack that forces me back.
"Evelyn — you must fight back. She will not stop until one of you is dead."
"I know she won't stop, but I won't kill her either, Aspis. I refuse to be what Father wanted me to become."
"She is trying to kill you. Your refusal to respond in kind is not nobility — it is suicide."
"And responding in kind would be murder. I am trying to break the cycle, which means not becoming what she expects me to become."
"Then how do you expect this to end?"
"With her alive, both of us alive, actually. There has to be a way."
Cassandra's blade comes for my throat. I duck under it, catch her wrist, try to lock the joint and force her to drop the weapon. She twists free and her elbow catches my jaw hard enough to send sparks across my vision.
I stumble back, and she presses the advantage.
The fight becomes brutal. Cassandra attacks with everything she has — no hesitation, no restraint, fighting with the desperation of someone whose identity depends on this moment.
I fight to neutralize. Every technique designed to disarm, to pin without piercing. I channel moonlight into barriers, throw blinding flashes, use locks and deflections that Sera taught me — controlling without destroying.
It's not enough.
Her blade finds my arm — a cut that opens the flesh from elbow to wrist, blood running hot down my fingers. I hiss through my teeth and keep moving.
"You are bleeding badly. Your reserves are depleted, and you cannot maintain this defense much longer."
"I just need her to listen. One moment where she hears me instead of Father's voice in her head."
"She has had years of that voice telling her who to be. You have had thirty seconds to offer her something different."
"Then I'll use every one of those seconds. Help me, Aspis, help me reach her."
"I do not know how to reach someone who has decided to be unreachable."
Another exchange. Another cut — this one across my thigh, shallow but painful, my leg threatening to buckle.
I give ground, retreating toward the cliff edge where the rocky shore drops away to the sea below.
"Fight me properly!" Cassandra screams, her face twisted with fury and something that looks almost like anguish.
"You always were a coward, hiding behind your excuses, refusing to be what you were meant to be. Stand and face me like the sister I was promised!"
My voice breaks on her name: "I am standing right here, refusing to raise a blade against you, and that is the hardest thing I have ever done."
"You call this hard? Try living your entire life knowing you were made to kill someone, try being forged into a weapon before you were old enough to understand what weapons do."
"I know how Father shaped you, but you don't have to be the thing he made. You can choose something different."
"There is only this — only us — only the prophecy that Father carved into my bones before I could walk. Make it easier for both of us and die!"
She drives forward — a combination that forces me to the very edge of the cliff, the stone crumbling beneath my heels, the sound of waves far below.
I channel moonlight into one more barrier, deflecting her killing stroke, and the effort costs me something vital. The power gutters in my chest like a candle in a storm.
"I don't want to kill you." The words tear out of me, raw and desperate. "Don't you understand what I'm telling you? I never wanted any of this. Not the prophecy, not the hatred, not years of being told one of us had to die so the other could live."
"One of us does have to die! That's what the prophecy demands."
"It demands that we stop, that one of us be strong enough to end the cycle instead of perpetuating it. I am trying to be that sister, Cassandra. I am trying to save us both."
"Save us?" She laughs — a broken, terrible sound. "You think you can save me? After everything Father did, everything he made me become, you think there's something left to save?"
"I have to believe that, or none of this means anything."
"Evelyn, she is positioning for a killing strike. Her weight is shifting forward."
"I see it."
"You must defend yourself. If she completes this attack—"
"I know what happens if she does it."
Cassandra's eyes meet mine across the space between us. For one moment — one suspended, infinite moment — something in her face cracks.
The fury recedes like a tide, and beneath it, beneath the conditioning, beneath twenty years of being told she is the weapon and I am the target, I see someone else.
A girl who wanted a sister and never got one. A child who learned hatred because love was never offered.
"Cassandra." I reach toward her with my empty hand, moonlight flickering around my fingers. "It doesn't have to end this way. We can both walk away from this, and we can be the sisters we were never allowed to be."
The moment stretches. Her blade wavers, and her eyes are wet with something she would never admit to feeling.
Then—
Her face hardens. Her grip tightens on the blade, and she screams — a sound of pure anguish, of a choice being made against everything soft that might have lived inside her — and lunges for the killing strike.
A thrust aimed at my heart: committed, final, with no possibility of pulling back.
I don't choose what happens next.
The power surges through the bond — not my will, not my decision, but Aspis reacting to a lethal threat with the only response the bond knows. Overwhelming force, the way a heart beats without permission.
Moonlight erupts from my body.
Not a barrier or a flash. A shockwave — massive, uncontrolled, a sun compressed into a single instant; the light is blinding, absolute, and the world disappears into white.
The shockwave catches Cassandra mid-lunge.
I see her expression in the heartbeat before the light takes her — surprise, then understanding, then something that might be relief. Her body lifts from the ground, thrown backward as if struck by the hand of a god.
She hits the stone outcropping behind her.
The sound is something I will hear in nightmares for the rest of my life. The wet crack of impact, the silence that follows, and the way her body slides down the rock and crumples at its base.
"Evelyn."
The light fades. The power collapses back into my chest, leaving me hollow, leaving me cold.
"No." The word comes out as a whisper. "No, no, no—"
I'm running, stumbling across the rocky ground, falling to my knees beside Cassandra, reaching for her with hands that still glow with the power that killed her.
"Evelyn. She is—"
"Don't say it. Don't you dare say it."
Cassandra's eyes are open. Her chest isn't moving, and blood pools beneath her head where the stone cracked her skull.
I didn't mean to do this! I was trying to save her! The moonlight did what my heart refused to do.
