(Edit who you're rescuing)

You were in traverse town. Ansem/Xemnas stood motionless—his arms at his sides, his head tilted slightly as if listening to something only he could hear.

Then... he smiled.

A slow, dark grin that sent a jolt through your spine.

"Did you really think..." he whispered, "...this was about the Heartless?"

Before anyone could react—

The ground beneath (Sora or riku) cracked.

you lunged for him—too late.

A black tendril shot up from the shadows below and yanked (Sora or riku) into the ground, swallowing him whole in an instant.

Ansem/Xemnas flickered—like smoke.

And then... he was gone.

Only his voice remained, echoing from every shadow:

"He's not in this world anymore... but if you want him back..."

A whisper now:

"Follow me into the dark."

Silence.

The Heartless were gone.

(Sora or riku) was gone.

And Ansem/Xemnas?

He was already waiting… deeper in the shadows than ever before.
