Zeal Palace 
We've made it to the end of the Ocean Palace.
Now is the time to turn back, nu...
There's no turning back now.
It's time to end this.
We shan't allow thee to meddle with Lavos, Queen!
Schala...!
Crono...! The Red Knife! Crono, use the old man's knife to stop the Machine!Let's do this.
Wait a minute...
Seems the Ruby Knife was the original form of the Masamune, before being transformed by the powers of the Mammon Machine.
It's coming...!
N, no stop! That sword alone can't stop it! Lavos's Theme 
In the end, we were too late.
Lavos has awakened.
And its power is beyond our imagination.
We failed. We couldn't stop Lavos...
SILENCE 
Then, the Prophet...
I've been waiting for you, Lavos.
It is time to fulfill that vow. Feel my wrath, Lavos!!It seems the mystery man who knew all the events as they transpired was none other than Magus. And it also seems his intent in summoning Lavos in the Middle Ages wasn't to harness its power, but to defeat it. Though we stopped him the first time, now he has his chance...
Zeal Palace 
Hmph! A false prophet... You'll be a snack for the great Lavos!
This power can only end in ruin! Get away from there, Schala!
You cannot change fate now! Oppose me and I will destroy you also!
Come Prophet, feel the power of Lavos!
Aaah!! My powers are being drained!
I survived the darkness to defeat you, Lavos!
Take this, Lavos! Aaugh!!
Aughhh!!
This is from me to you! You shall enjoy eternal life...as part of Lavos!
Lavos's Theme 
We failed, even Magus has failed. Is this the end...?
Crono has just enough energy left to get up, watching as Schala and Magus are helplessly drawn towards Lavos.
We now have a chance to speak to everyone.
Crono... We can't leave Schala here. Aack...! Halt... Magus!
Isn't your life precious to you? Mwa, ha, ha!
What choice does Crono have? This is the entire reason we're on this journey. We've gone through incredible lengths to prevent the end of the world. He's got to see this through to the end.
You challenge Lavos with that battered body of yours?
SILENCE 
Can one man truly defeat such a great creature?
...No.
In order to save his friends, and even his enemy, Crono makes the ultimate sacrifice.
It was all for naught.
Away from Lavos, Magus, Schala, and our party arrive back before the Mammon Machine. But there's one vital person missing...
We must plan our escape! The Palace crumbles!The Ocean Palace is falling apart, and Lavos has been awakened. But can we even escape in time...? And if so, where could we even flee?
Manoria Cathedral 
I know you can't forgive her but...
I'm so sorry! Now, off you go!
In the end, Schala uses the last of her magic to save us.
...and this is the last we ever see of Schala.

Video: End of an Era Lavos's Theme 
Lavos is now awake, aware that humans were draining its energy to fuel their society.
It does not take this news well.
We all saw this coming. A perfect floating utopia that clearly doesn't exist by the time of the Middle Ages.
A nation run by a vain and power-craving leader, willing to do anything for the sake of power, including risking the lives of her own children.
Of course this is how it ends.
Even the Earthbound Ones cannot escape unscathed.
Lavos won.
