The party has set off in search of Lyon! And the troops return with news that Lyon has moved north. The search has led to Mt. Neleras, deep within the Darkling Woods! 

The scorching heat and sulfur stench render the area unfit for human habitation, and by that I mean several Gorgon eggs! 

(Y/N): Hey L'Arachel, I want to ask you something. 

L'Arachel: Yes? 

(Y/N): Do you think there's some way we can save Lyon? If he's been possessed by the Demon King, there has to be some way to separate them. 

Eirika: Please L'Arachel, if there is a way, then we have to try! Rausten is the spiritual heart of Magvel. They keep the ancient lore. You're their princess. You must know something about the demons of legend. Is there anything that can save Lyon?

L'Arachel: I'm so sorry, Eirika. To the best of my knowledge, there is no way to aid him.

Eirika: That can't be! There must be something! Any clue, no matter how slight...

L'Arachel: Our oldest legends tell us just this... Only one person has ever been able to shake off the Demon King's domination. Rausten's founder, Saint Latona the sure-hearted, shattered his fetters. If one possesses a strength of will beyond that of normal men... Only then can one throw off the shackles of the Demon King. But you saw it for yourself, Eirika, with your own two eyes. Your friend Lyon's body has already been claimed by the Demon King. Once it's gone that far, there's nothing that can be done. When the Demon King takes over someone, he devours his spirit, their very soul. Even if his hold on Lyon's body could be released, that body would have no soul. There is no power in Rausten... not even the Sacred Stone... that can perform so great a miracle as to restore a shattered soul.

Eirika: But... Lyon...

L'Arachel: Eirika... I understand how you feel, but the prince is gone. The Lyon you knew no longer exists. It's more important now that you care for yourself. If we pursue the Demon King, we're likely to suffer for it. I want you to return to Rausten Palace and rest yourself.

Eirika: Thank you, L'Arachel. However, I must stay with the company. I have to believe there's something I can do to help him. Lyon was always so kind. He wanted nothing more than to help people. It's too terrible to picture him imprisoned by the Demon King. Imprisoned... with no hope of salvation.

You all then notice a bunch of eggs nearby. 

Ruby: Are these eggs? 

Myrrh: No, Gorgon ... Eggs. 

Weiss: WHAT?! 

Ephraim: He led us into a trap! 

(Y/N): Okay everyone, just stay close and trust me! 

You started to lead everyone around the Gorgon eggs as not to have any of the Gorgons hatch! 

(Y/N): We're heading in the right direction! This should be the way! 

Blake: We still need to be careful. If this was a trap, then who knows what else the Demon King has planned.
