The thing wearing Lian's face climbed from the Birthwell, its fingers leaving **blackened burns** where they touched the stone. It tilted its head, studying them with eyes that were not eyes—just **voids** where something infinitely older peered out.
*"You look tired, big brother,"* it said in Lian's voice. *"All those lives spent running from me."*
The real Lian stumbled back, her dagger raised. **"Don't listen—"**
Kai's shadow **moved**.
Not to protect him.
To **kill** him.

**The Shadow's Betrayal**
It fought like Kai had in his **third life**—all precision and cruelty, every strike aimed to maim rather than kill.
*"You remember now,"* it hissed as Kai barely dodged a **meridian-severing palm strike**. *"You helped* build *the cage. You* chose *this."*
Kai's crystallized arm **blazed with golden cracks** as he blocked. **"I was wrong."**
The Sin-child laughed—a sound like **breaking glass**.

**The Cage Revealed**
The palace **collapsed inward**, walls dissolving to reveal the **true prison**:
A **web of living starlight**, each thread the **still-beating heart** of a sacrificed god. At its center, the Birthwell pulsed like a wound.
The Sin-child pressed Lian's stolen hand to Kai's chest. **"You're already half-mine. Why not come home?"**
Lian's dagger found its throat.
**"Because I'll unmake you first,"** she snarled.
The blade **sank in**.
No blood. Only **darkness pouring out**.
