The Heart of Atlantis.

What?

[Louder, excitedly]

It's the Heart of Atlantis. That's what the shepherd was talking about. It wasn't a star; it was some kind of a crystal. [Holds up Kida's crystal] Like these. Don't you get it? The power source I've been looking for, the bright light you remember; they're the same thing.

It cannot be.

It's what keeping all these things- You, and all of Atlantis alive.

Then, where is it now?

I don't know, I don't know. You'd think something this important would be in the journal, but it- [Pauses as he realizes] Unless...the missing page.
