(The scene opens with the royals walking near a village a few days later. Nyx is with them. Nobody is speaking)
Camilla: Corrin?
Corrin: Yeah?
Camilla: I'm worried about you.
Corrin: There's no need to worry. I'm fine.
Leo: You've barely said anything since Lilith...
Corrin: I've had a lot to think about. That's all. Let's drop it.
Nyx: ...
Xander: I don't want you holding all this in. You can talk to us.
Corrin: I know that, but I don't want to talk right now. I want to go into action. I refuse to let Lilith's sacrifice be in vain. I want to corner Iago and—
Elise: Corrin! Look over there!
(Elise points to a faction of Faceless breaking apart from the army to head to the nearby village)
Corrin: I have to go make sure those people are alright!
Xander: Corrin, stop! What will Father do when he sees you're gone?!
Corrin: He'll just have to deal with it, alright?! I'm not going to let anybody else die!
(Corrin leaves)
Azura: I need to make sure they don't get into any trouble...
(Azura leaves)
Elise: We can't just let them get into any trouble, right?
Camilla: Come on... I doubt Father will miss us if we're quick. The army isn't moving quickly right now anyways.
(The other royals leave)
Nyx: ...
(Nyx follows them. The scene changes to show Mozu with her mother)
Mozu : Mother! Come on, we need to get out of here!
Old Woman: Mozu, I—
(The Faceless strikes the woman down)
Mozu : No! Mother!!
(Corrin appears)
Corrin: Damn it! We're too late!
(Azura appears)
Azura: Wait... Over there! It's a young woman!
Corrin: If there's a survivor, there's a reason for me to fight. Let's save that girl!
(The battle begins. Due to her late join time, Mozu is a pre-promoted Master of Arms)
(Corrin talks to Mozu)
Corrin: Hey! Are you okay?
Mozu : Y-Yes... Who are you?
Corrin: My name is Corrin... What's your name?
Mozu: I'm Mozu...
Corrin: You seem to be holding up pretty well, Mozu...
Mozu : I-I knew war was coming, so I started training to protect Mother... But she...
Corrin: ...I understand. Come on. I'll protect you.
Mozu: T-Truly?
Corrin: Of course. That's what I do. I don't leave people in need behind, and that includes you.
Mozu : Thank you...!
Corrin: Come on. Let's take care of these things.
(After the battle, Corrin and Azura stand before Mozu regardless of if she was defeated or not. She will join the party either way)
Corrin: I'm glad to see you're safe.
Mozu : Thank you for the help... I know I couldn't have fought them all off on my own...
Azura: What is a warrior like you doing in this small village?
Mozu : I wouldn't call myself a warrior... I trained with the former soldiers of the village, but... They're gone now... And Mother...
Azura: I'm sorry for your loss...
Mozu : I heard an invasion was coming... I wanted to be able to protect them, but I failed... They're all gone...
Corrin: I'm glad you're safe at the very least... I need you to live. For the sake of the people who died, live. You deserve as much.
Mozu: You think so...?
Corrin: My party... It's not exactly the best one, but I'm sure we'd be glad to have you. I understand we can't replace the family you lost, but it's an offer I believe I should extend.
Mozu : I... I think I'll take you up on that offer... Thank you for everything.
Corrin: It's my pleasure.
(Mozu leaves)
Corrin: Azura, can you help her get settled?
Azura: Of course.
(Azura leaves)
Corrin: I have some business to take care of with a certain strategist of ours...
(Corrin approaches Nyx, who is standing with Leo away from the rest of the royals)
Corrin: Nyx, we need to talk.
Nyx: ...
Leo: You don't need to close yourself off, you know.
Corrin: You haven't said anything since Iago lashed out on the Eternal Stairway. You can't keep closing yourself away this way. Talk to us.
Nyx: I... Fine...
Leo: Go on.
Nyx: What he said was true... I can't deny it.
Leo: I want a full explanation.
Nyx: I was born as one of the three royals of Nestra. I grew too obsessed with my magic and lost control... Many Nestrans lost their lives. I was trapped in this youthful body for countless decades as a result... The only survivors I know of were my two brothers.
Corrin: And one of them was Iago?
Nyx: Yes... He was driven insane by the sight of seeing that murder at a young age. He was too wrapped in magic soon after, and now, his aging is still slowed. He turned to dark power in his grief, and now... You see the result.
Corrin: I don't understand... What about the now deceased ruler of Nestra?
Nyx: He's a descendant of our older brother... Now that he's gone with no heirs to the throne, I guess I'm the only one left...
Leo: We can't trust him to take over a nation he happily ravaged.
Corrin: Nyx...
Nyx: I understand if you want to leave me behind for this. I don't deserve to be here with so much love after all I've done.
Corrin: That's not true. I understand that what happened was awful, but... I think you're atoning for it now. You're saving lives rather than taking them...
Nyx: I'm a monster. Can you really say you're glad Lilith gave her life because of me?
Corrin: It wasn't your fault. Iago was to blame—
Nyx: But I caused us to go to the Astral Plane!
Leo: Nyx!
Nyx: ...
Leo: You weren't responsible for that. You couldn't have known. I know what you did in the past was horrible. We all do bad things, and it's hard for you to move on in this case. I understand. However, I don't want you to be so hard on yourself.
Nyx: But—
Leo: Quiet. You're making up for it now. You're atoning. Instead of going further to hurt others, you're saving lives. You're not like Iago. He's a madman driven by a lust for power to hurt others because he suffered. You've done awful things, but you're not trying to hurt people. You're being good now.
Nyx: ...
Leo: Whether you remain with us is ultimately your choice, but I know we'd be glad to have you around still... Besides, that knife he used to hurt you... It technically belongs to you. He didn't take it for himself.
Nyx: Spectre...
Leo: It's yours as the soon-to-be ruler of Nestra.
Nyx: I don't think you understand what you're saying.
Leo: Nyx, you're next in line to rule Nestra. I believe you know what you have to do.
Nyx: I'm not worthy of Nestra.
Leo: I know it seems that way now, but... Listen, there probably isn't anything I can say to convince you.
Nyx: ...
Leo: However, I want you to know... If you want to rule over Nestra, I'll gladly help you. Even if you don't, I at least want you to come and see the land. If you wish it, I'll stay with you and help to rebuild.
Nyx: I am not deserving of such kindness...
Leo: You may not feel it, but I am sure of it. I'll be here for you every step of the way. The past hurts, but you're going to atone for it. You've already started down that path. I'll help you see it through.
Nyx: Prince Leo...
Leo: No. Just Leo.
Nyx: Thank you... It would be an honor.
Corrin: We'll keep you in our army as long as you so wish it, Nyx.
Leo: What about Spectre?
Nyx: ...My brother was not deserving of our family's royal treasure. I'll use it from here on out to undo the harm he caused.
Corrin: I think that's fitting.
Nyx: Lord Corrin, I know I can't make up for what happened to Lilith, but...
Corrin: You didn't cause that... But if you want to help me get revenge and lay her soul to rest, stay with us to defeat Iago.
Nyx: Of course... Thank you for speaking with me.
Leo: It's our pleasure... Let's get back to camp. Father may have noticed we went missing.
Corrin: You're right... Off we go, I suppose.
(Nyx, Leo, and Corrin leave)

And here comes Mozu, but instead of a trainee, she's a prepromote. I know, it's a weird take, but I had to balance her somehow
