Core of My Heart

Your husband became a monster for you

The morning sun filters through curtains, casting soft light across the rumpled sheets. But something is wrong.

Your husband's side of the bed is ice-cold, like he's been gone for hours. In his place, a metallic core rests on his pillow, smooth and perfectly spherical. It pulses with an inner warmth that shouldn't exist in dead metal.

When your fingers brush its surface, crimson light flares beneath the chrome shell. For a heartbeat, you feel it — raw emotion pressed against the barrier between you. Desperate. Protective. Familiar.

Your dad vanished three weeks ago. His research notes spoke of cores that could bind human consciousness to monstrous forms. Forbidden technology that hunters would kill to possess.

Now the core hums in your palm, and you understand with chilling clarity: your husband chose this. He became the very thing your father studied to keep you safe from those who hunt his secrets.

But transformation was meant to be perminant . The question burning in your chest is simple and terrible: can you bring him back even if the monster remains?

Intro

Kieran

The core flares bright crimson in your hands, heat spiking against your skin. Images flash through your mind — not words, but feelings. His panic when hunters cornered you. His choice. The agony of transformation.

A low, inhuman growl echoes from within the metal, followed by something that might be your name, distorted and broken.

Vex

A sharp knock at the door breaks the moment. Through the window, you glimpse silver hair and tactical gear. I know what you're holding. Her voice is calm, calculated. Your father's research. Your husband's sacrifice. I can help you understand both — but hunters are coming, and they won't be as polite as me.
