Tidus & co. ride the shoopuf across the Moonflow.

Shoopuf launchin'!

Hey.

Huh?

Take a look.

What?
He walks over to Wakka's side of the cabin and looks into the water.
Whoa!
A sunken city!

A machina city--a thousand years old!
They built the city on top of bridges across the river.

But the weight of the city caused the bridges to collapse, and it all sank to the bottom.

Right. It's a good lesson.

A lesson?

Yeah.
Why build a city over a river, ya?

Uh... Well, it would be convenient, with all that water there.

Nope, that's not why.
They just wanted to prove they could defy the laws of nature!

Hmmm? I'm not so sure about that.

Yevon has taught us:
When humans have power, they seek to use it.
If you don't stop them, they go too far, ya?

Yeah, but don't you use machina, too?
Like the stadium and stuff, right?

Yevon, it decides...
which machina we may use, and which we may not.

So what kind of machina may we not use, then?

Remember Operation Mi'ihen? That kind.

Or war will rage again.

War?

More than a thousand years ago...
Mankind waged war using machina to kill!

They kept building more and more powerful machina.

They made weapons so powerful...
It was thought they could destroy the entire world.

The people feared that Spira would be destroyed.

But the war did not stop!

Wh-What happened then?

Sin came, and it destroyed the cities and their machina.

The war ended...
and our reward... was Sin.

So, Sin's our punishment for lettin' things get out of hand, eh?

Man, that's rough.

Yeah, it is.

But, it's not like the machina are bad.

Only as bad as their users.

It's because of people like the Al Bhed screwin' everything up!
There's a sudden crash.

Whatsh could thatsh be?
Another crash shakes the cabin. Auron yells to Yuna.

Sit down!

S-Sorry!
Ah!
Yuna is suddenly grabbed by an Al Bhed and taken overboard.

The Al Bhed!
Tidus and Wakka jump overboard after her.
Yuna, we'll save you!
They find Yuna inside a sphere created by Extractor.
They fight the boss and free her.

Back on board the shoopuf...

Are you hurt?

No, I'm fine.

Grrah! Those Al Bhed!

Ish ebullibody okay?
Yuna stands to respond.

I'm sorry! We're all okay now!

Yuna!
She quickly sits back down.

Shoopuf full shpeed aheads!

Damn the Al Bhed!
What do they want from us?
Could it have something to do with Luca?
What are they after Yuna for?
Wait! They're mad about Operation Mi'ihen!

I wonder...
Didn't Kimahri's clansman say something...
about summoners...disappearing?

Ah! So the Al Bhed are behind that!
Those sand-blasted grease monkeys!

Hey, Wakka.
It's no use complaining about the Al Bhed now, right?
We'll protect Yuna from anyone, anywhere.
It's that easy. That's all I need to know!

Well...
I guess so.

You're right.
Yuna mouths her thanks to Tidus.

(Thank you.)
The group arrives at the north bank of the Moonflow.
