Thanks to the arrival of reinforcements, Eirika's group successfully repelled the Grado invaders. Still, Jehanna Hall remains under siege, on the edge of ruin. En route, our heroes are determined to rescue Queen Ismaire and recover the Sacred Stone of Jehanna. 

1 1/2 years ago... 

Lyon: ...I yield. The point is yours, Eirika. You're swift, aren't you? Compared to you, I'm-- I've been bested at fencing by a woman. Pitiful crown prince, am I not?

Eirika: That's not true...

Lyon: Oh, no, Eirika. It is. The people need a strong ruler. They don't want a weakling like me. They want the strength you and Ephraim share. My body is frail. I prefer to spend my time locked away in the castle, reading... I think my father would be better served if someone else took my place. I'm sure all of our retainers feel the same...

Eirika: You're wrong, Lyon. An emperor without compassion will never hold the people's love. And one day, your compassion will surely save us all. I believe that.

Lyon: Eirika... Thank you. Yes. I...I will do my best. Even though I lack your strength, there must be some good I can do.

Eirika: There is.

Lyon: By the way, Eirika... If it please you, would you accept this?

Present day... 

Seth: Is there something wrong Princess Eirika? 

Ruby: Yeah, you look like you've seen a ghost. 

Eirika: No. It's nothing. 

Seth: Jehanna Hall has been completely occupied by Grado soldiers. I'm sorry to report that Queen Ismaire is already...

Innes: And the one giving orders to the troops in the palace is Crown Prince Lyon?  Frelia's spy network reports that Prince Lyon is an initiate of dark magic. If this is true, even approaching him will be a serious challenge. I'd heard the prince dislikes violence. However, it could all have been a ruse.

Blake: If we don't retake the palace, we don't have a chance of defeating Grado. So, we have to save the Queen! 

In the Throne Room... 

Ismaire is being held captive by a mercenary named Carlyle. 

Carlyle: Queen Ismaire... Please do not resist. I have no desire to see you harmed.

Ismaire: Carlyle... Why have you betrayed us? After all these years of loyal service as Jehanna's most decorated commander... Without you, I could not have ruled these long years since my husband's passing. It was through your unwavering support alone that I still sit upon the throne. You are the cornerstone of Jehanna. You have held my trust more than any man. So tell me why. Why have you betrayed us? Why have you betrayed me?

Carlyle: Your Highness-- No... My queen... Ismaire... It is your own fault. You are too lovely, my queen.

Ismaire: Carlyle...

Carlyle: The first time I met you, twenty years ago now... I saw you in the garden of this very palace... and I was bewitched. Your pale beauty far surpassed that of any flower. I was in the grips of an unforgivable desire... You were the wife of my king, to whom I'd sworn life and loyalty. I told myself a grand lie that day. I told myself I could be happy simply serving you as your most loyal knight.

Ismaire: ......

Carlyle: After years of duty, years of service, years of...of silence... I became aware once more of the feelings I'd buried deep within myself. How could I leave this world without expressing my true desires? Could anything be more desolate? More devoid of meaning? That is when I made my decision. I would follow my heart and claim your hand as my own.

Ismaire: Carlyle... You forget yourself. You ruin our country and kill our countrymen. Did you think I would be pleased? Did you think I would love you for this?

Carlyle: I need no country. I care nothing for my countrymen. I can see nothing but you. If you would only be mine...

Ismaire: Carlyle.

Caellach and Lyon then appear. 

Caellach: Hey, Carlyle! Impressive work you've done here. My compliments.

Carlyle: ...I gave you everything I promised. I opened the hall to your forces.

Caellach: Yes. The palace is mine. My palace... Oh, how I do like the sound of that.

Carlyle: Do whatever you want with the royal treasury. The only treasure I wish to leave here with is the queen of my heart.

Caellach: Oh, yeah, about "your queen"... There's been a change of plans.

Caellach grabbed Ismaire by the neck. 

Ismaire: AGH! 

Caellach: Don't move, Carlyle. You twitch, and the queen dies.

Carlyle: Blackheart! What is the meaning of this?

Caellach: Calm down. You'll get her back as soon as I'm done with her. Jehanna's Sacred Stone is around here somewhere. I've got to find it and destroy it. I need this woman to guide me to its hiding place.

Carlyle: Do not lay a hand on my queen!

Caellach: Don't get so incensed. I'm not going to harm her. I'm not like that freak Valter. I'm kind to women. But if you make a wrong move, you'll lose your prize. Understood?

Carlyle: Yes...

Caellach: There are some annoying pests outside who think to win back the hall. I want you to take care of them. Lose, and the queen will never be yours.

Carlyle: ...... If my queen comes to any harm in your care...

Caellach: Yes, of course. I know all about the might of your sword arm. As long as the Sacred Stone is destroyed, you'll get all you ask for.

He then begins to drag her off. 

Caellach: Greetings, Prince. Let's get going.

Lyon: Caellach... You will put an end to this. Destroying the Sacred Stones is... Ugh...ack...

Before Lyon could finish his sentence, he felt pain inside of him! 

Caellach: What's this? Are you still ill? You know, you're not very princely. C'mon. Follow me.

Soon... 

Caellach, Lyon, and Ismaire enter a room. 

Caellach: This is as good a place as any. All right, Your Majesty. Hand over the Sacred Stone.

Ismaire: ...I know nothing of the Sacred Stone's keeping place.

Caellach: Don't waste my time. My partner here sees everything. When the rebellion began, you went straight to the palace altar. You had hoped to prevent us from smashing the Sacred Stone. But you have the Stone of Jehanna with you right now, don't you?

Ismaire: ......

Caellach: Hand it over. Cooperate, and I'll let you live.

Ismaire: ...I cannot.

Caellach: Oh, give it up, will you? I've no time for games. If you resist, I'll just kill you and take it anyway.

Lyon: H-hold! You mustn't harm her, Caellach...

Caellach: Shut up, Prince. My orders come from higher than you. You're not going to start disobeying his word, are you?

Lyon: ......

Caellach: Last chance. Give me your Sacred Stone.

Ismaire: ...I cannot.

Caellach: Ha ha! A queen to the end. I like you. You've got guts. Good-bye.

Lyon: Ah!

Lyon watched as Caellach stabbed Ismaire to death! 

And then he finds the Sacred Stone and destroyed it! 

Caellach:  And another Sacred Stone has been destroyed. Grado, Frelia, and now Jehanna... Only two stones remain.

Ismaire: Uh ... ah .

Lyon: Ah... What should I do? C-Caellach... You must help her.

Caellach: Leave her. Let her last breath be a harsh and ragged rasp. She's not long for this world. Why, if you really wanted to help her, you'd deliver the final blow yourself!

Lyon: N-no. I couldn't.

Caellach: ...What a joke. I have a little work to wrap up in the hall before we leave. You should hit the road pretty soon, too, Prince.

In the throne room... 

The heroes had defeated their enemies. 

Eirika: Say, where is Queen Ismaire? 

Innes: I heard she was in the throne room, but there's no sign of her. And there's no Sacred Stone, either.

Ruby: Then let's get to searching! 

Yang: Hopefully, we're not to late, or we're in for some deep shit. 

Then Lyon appeared. 

Eirika: Lyon!

Lyon: Eirika...

Eirika: Wait, Lyon! Don't run away! My brother and I have been so worried about you... We know more than anyone the gentleness of your spirit. Your father is deranged, isn't he? That's why Grado invaded Renais, right? Tell me, Lyon... Please... Tell me what has happened.

Lyon: I'm sorry, Eirika. I've wanted to see you and Ephraim for so long now... I wanted to see you so that I could apologize. The invasion of Renais... I couldn't stop it. I'm sorry, but I still cannot talk to you. Not yet...

Eirika: You... You have a reason, don't you?

Lyon: Mm... I can't talk about it now, but... I promise I will tell you everything someday.

Eirika: I see... I believe you, Lyon. I must tell you, I'm a little relieved. I was afraid you'd changed as much as your poor father has. I'm so glad.

Lyon: Me, too, Eirika... No, you have changed. You're even more beautiful than you were before.

Eirika: L-Lyon...

Lyon: I'm sorry, I have to go. But please remember this. This war started because I was too weak to stop it, but... I'll always be your friend.

Lyon then leaves. 

Soon they found Ismaire. 

Innes: Quen Ismaire! 

Seth: We're too late. 

Eirika: QUEEN ISMAIRE! 

Ismaire: Who are you? 

Eirika: Eirika... Princess Eirika of Renais.

Ismaire: You must listen... The Stone of Jehanna has... been destroyed. The one who tempted Carlyle has crushed it...

Eirika: Jehanna's Sacred Stone, too?

Ismaire: The dark stone... Carried a dark stone... It is...the origin of all this... It should not exist...

Eirika: A dark...stone?

Ismaire: Princess Renais... Eirika... I have something... Something you need take...

Eirika: This...

Ismaire: It's one of the Sacred Twin relics, unique to House Jehanna... He who would rule our land must possess it... I've watched over it since my husband passed away. I've kept it safe, waited for the day I could give it to Joshua... But...now... I...

Eirika: Queen Ismaire!

Ismaire: Joshua... My...dear, sweet child...

She then passes on. 

Eirika: Queen Ismaire. 

A soldier runs in. 

Soldier: Fire! Fires have broken out all through the hall. 

Eveyrone: WHAT?! 

The group was out of the frying pan and into the fire.
