Find the Way to Get Back To Hollow Bastion

Rook: Tell me what happen?

They tell them about what happened

Rook: I see. So the darkness are flowing out from that Symbol.

Ben: No wonder, there are more and more Heartless everywhere. And the only way to stop them is...

Ace: Get the Symbol, right?

Rook: Maybe. But no one knows what will happen once you got it.

Ace: But we can't just stay here. We gotta do something, I've got a friend back here.

Rook: That's right. You have 4 more friends to worried about. You're team is still missing and Duck's Sword must have been born of the captive princesses hearts just like that Symbol you saw. Of course, without Lexi's heart. It remained incomplete. Once that sword was destroyed, the princesses' hearts should have been freed. Don't worry, Ace. If anyone can save your friends, you can.

They went to Max

Ace: Max, I need to got back to Hollow Bastion

Max: I don't think I can let you do that, Ace. The Heartless there are multiplying by the minute. They'd destroy your train.

Ace: Then what can we do?

Max: Simple. Go around 'em instead of through. Install a new navigation gear and take a new route.

Ace: A new Gear? From where?

Max: The secret waterway. When I came here 10 months ago, I stored it there in case I ever needed it. Never though a bunny would be the one to use it.
