(The chapter opens to show Corrin and Azura together in the palace of Valla. They stand before a large pair of doors leading to the throne room.)
Corrin: This is it... We're almost there.
Azura: This must be the throne room, so on the other side of these doors...
Corrin: Yeah. We're going to have to fight Anankos... I'm ready. Are you?
Azura: Of course. We've come too far to back down now.
Corrin: I'm glad we agree... Let's get in there.
?: Not so fast.
Azura: Who's there?
(Mikoto appears.)
Corrin: M... Mother!
Azura: What are you doing here?
Mikoto: I cannot let you breach this door... Anankos is on the other side.
Corrin: What? You're under his spell! You have to let us free you, Mother!
Mikoto: I fight for the sake of my first love, Corrin... This is a decision I will not go back on...
Corrin: First love...?
Azura: What are you talking about?
Mikoto: I'll tell you nothing so long as you insist on standing against him. You can surrender and hear the truth or fight me without knowing.
Corrin: ...Surrender was never an option this far into the war. We've got a continent to save, and... We can't back away now.
Mikoto: Tragic... Truly, I was hoping that you would decide on something else... But if you insist on fighting... Let the game begin.
(The battle begins. The objective is to defeat the boss, Mikoto, who stands in front of the doors to the throne room. There are various soldiers scattered about the room of mixed Hoshidan and Nohrian classes. Mikoto's inventory holds a staff called Miranew.)
(If Corrin initiates combat with Mikoto, the following dialogue plays out.)
Corrin: Mother... I knew this was going to happen, but I still didn't want it to end this way.
Mikoto: Corrin... Surely you must know of what you must do... Unless you wish to join me...
Corrin: You know just as well as I do that such is not an option... I'll free you from this madness, Mother. I promise!
(If Azura initiates combat with Mikoto, the following dialogue plays out.)
Azura: I had been hoping that things would be different with you, but... It appears my prayers were in vain.
Mikoto: I have already made my choice just as you have already made yours.
Azura: I see... Then allow me to show you just how confident I am in my decision here and now.
(If Ryoma initiates combat with Mikoto, the following dialogue plays out.)
Ryoma: Mother... It was inevitable that we would find ourselves at odds here, but... Still, I find it to be tragic that it had to end this way.
Mikoto: Just as stoic as ever, I see...
Ryoma: I have a duty to uphold here today, and I will not let you get in my way. Prepare yourself.
(If Hinoka initiates combat with Mikoto, the following dialogue plays out.)
Hinoka: It feels like we were mourning your death just yesterday, but now... Now we're fighting against you.
Mikoto: The world is cruel, is it not...?
Hinoka: That's putting it lightly... But that won't stop me from showing you what I am capable of!
(If Takumi initiates combat with Mikoto, the following dialogue plays out.)
Takumi: Damn... I didn't want it to have to be like this, Mother. I knew it was inevitable, but that didn't mean I had to like it.
Mikoto: It truly is upsetting...
Takumi: But I'm not going to let that hold me back. You need to be freed from the clutches of Anankos, so I'll do what I must.
(If Sakura initiates combat with Mikoto, the following dialogue plays out.)
Sakura: Mother... I'm so sorry that it had to end like this...
Mikoto: Oh, Sakura... You knew this was bound to happen, didn't you...?
Sakura: We all did, but... That doesn't make it any easier. Either way, I know what I have to do...!
(If Orochi initiates combat with Mikoto, the following dialogue plays out.)
Orochi: Lady Mikoto... I wish there was something we could do aside from fight you...
Mikoto: You know that there is no other choice... Aside from you leaving your companions behind, that is.
Orochi: You know me better than that.
Mikoto: I do... Which is why I must ask you now to be ready for what is to come.
(If Reina initiates combat with Mikoto, the following dialogue plays out.)
Reina: I never wanted it to come to this, but I doubt anyone would have hoped for such a cruel twist of fate... It's upsetting, but I know there's no way to change it.
Mikoto: You've already made up your mind, haven't you?
Reina: I made my choice long ago, and I won't be backing away from it now.
(If Yukimura initiates combat with Mikoto, the following dialogue plays out.)
Yukimura: After this ends, you will be able to rest in peace with your husband... He is sorry for what he did in the capital, Lady Mikoto.
Mikoto: ...
Yukimura: It wasn't his choice to attack you, nor is it your choice now to assault us... I'll bring you the salvation you require here and now, my lady!
(If anyone else initiates combat with Mikoto, the following dialogue plays out.)
Mikoto: I fight in the name of Anankos... All those who dare to combat him must suffer...
(When Mikoto is defeated, the following dialogue plays out.)
Mikoto: Thalone... I... I am free... I wish you could be as well...
(After the battle, Corrin, Azura, Ryoma, Hinoka, Takumi, and Sakura surround Mikoto.)
Mikoto: Children... Thank you for your help... I don't know how to thank you...
Hinoka: You don't need to... We did what we had to in order to save you...
Mikoto: Corrin... Before I die, I... I must tell you the truth...
Corrin: The truth...?
Mikoto: Yes... You were born in Valla under the name of Cerulean... And I was Aquaria at the time...
Ryoma: Aquaria... I recall that being the name of a princess of Valla before it fell...
Mikoto: Yes... Arcadia... Arete... She was my older sister...
Corrin: You mean... I'm royalty of Valla?
Mikoto: Yes... Your father's name is Thalone... Though you know him now as the reincarnation of Anankos...
Corrin: Wait... The person that we've been fighting against all this time...
Mikoto: Is your birth father... Yes...
Corrin: I don't know what to say...
Mikoto: After the invasion of Valla, I took you and ran... We found Hoshido, and I changed our names...
Corrin: And then you married King Sumeragi...
Mikoto: I did... I wanted to keep you safe, Corrin, but... That all fell apart horribly...
Takumi: If Azura was the daughter of Arete, then...
Azura: ...That means Corrin and I are cousins...
Mikoto: Yes... You look just like your mother, Azura... I wished to take you in after putting the pieces together, even if you were suspected to be from Nohr...
Sakura: That's why Azura was accepted into the family so quickly... You figured out that she was your niece...!
Mikoto: You understand... I'm afraid my time is growing minimal now... Please know that I care greatly for all of you, and I'm... I'm sorry.
Corrin: Mother, you don't need to apologize at all! Father... He was driven mad by his power. He did all of this, and you were simply one of his puppets!
Mikoto: Even so, I... I wish to make up for what I have done... This staff is called Miranew... It was once a legendary weapon of Valla, but it was lost in the invasion... Thalone recovered it and gifted it to me, but... I now pass it on to you...
Corrin: Thank you, Mother... I won't let you down. I'll end this war for your sake.
Mikoto: I'm glad to hear it...
(Mikoto disappears into purple fire.)
Ryoma: She... She's gone.
Hinoka: Mother...
Sakura: It's like that wound left behind by her death was torn open all over again...
Takumi: ...We're going to kill Anankos, Thalone... Whatever his name is, it doesn't matter. We're going to take him down a peg for the sake of those he killed. They're counting on us.
Corrin: Yes... You're right. It's what Mother would have wanted from us... Prepare yourselves, everyone. The final battle is ahead.
Azura: Are you sure you want to press on now...? You're grieving still. We all are.
Corrin: Even so, I want to kill Anankos for what he's done. It's the least I can do for the sake of Mother.
Azura: Understood...
Ryoma: We'll finish the preparations. On your mark, we storm into those doors and kill the monster once and for all.
Hinoka: The end is within sight... And we're going to finally bring it to a close today.
(Ryoma, Hinoka, Takumi, and Sakura walk away. Afterwards, the Yato begins to glow.)
Corrin: What's going on...?
Azura: It's changing shape...!
(The light fades to show the Yato has grown longer, brighter, and stronger.)
Corrin: The Fire Emblem...
Azura: What?
Corrin: I don't know... The name just came to mind, and... I think that's what it is now.
Azura: I trust you then...
Corrin: For the first time in so long, all of the legendary weapons are together again. From Hoshido, Raijinto, Senshi, Fujin Yumi, Sanata, and Adriashe... From Nohr, Siegfried, Sukeyu, Brynhildr, Moonlight, and Spectre... From Valla, Yato, Safaia, Asazhi, Ragnarok, and Miranew... Everything has come together at long last.
Azura: I bet it's the union of these weapons that has brought this power to light.
Corrin: I believe so as well... Together, their power has changed the Yato into the Fire Emblem.
Azura: Yes... That seems to be the case.
Corrin: ...I'm going to use this power to defeat my father once and for all. It will be a symbol for peace walking into the coming future. Destiny is watching us with waiting eyes, and I am going to prove myself worthy of its attention. History will know our names as those who toppled a god and ushered in a new era of peace for all inhabitants of Pheuyura.
Azura: Of course... We're all here for you, Corrin.
Corrin: Thank you, Azura.
(Lilith approaches the two.)
Lilith: Corrin? Can... Can we talk? In private?
Corrin: Of course...
Azura: I'll leave you to it.
(Azura walks away.)
Corrin: What is it, Lilith?
Lilith: I need to talk to you about your father... There's more to the story than your mother was aware of.
Corrin: What do you mean?
Lilith: After you and your mother left Valla, Thalone stayed behind to cover for your escape, but... He survived. The invisible soldiers of Valla defended him and refused to hurt him. He was their leader because he was the reincarnation of Anankos... But he's not like your mother or aunt.
Corrin: How so?
Lilith: He was never born... Instead, he was simply manifested into existence. One day he wasn't there, and the next, he was. There was no human blood to dilute his draconic power, and because of that... He was driven mad. Anankos was always the strongest out of the three dragons, and it became too much for him once he was in the body of a mortal.
Corrin: I see... And that draconic blood...
Lilith: It passed on to you. Between the power of your mother and your father's draconic strength, you became the first in generations to have the power to shift into a dragon.
Corrin: Wow...
Lilith: Your father was desperate to find you. He... He created an artificial person from his own blood to find you. He longed to be your father, to care for you since he was never given the chance. The child he made had only draconic blood, and... She has the same power as you.
Corrin: You can't mean...
Lilith: Yes... It's me. Corrin, I... I'm your sister.
Corrin: I... I don't know what to say...
Lilith: I understand it's a lot to process at once, but... I thought you had a right to know. Now that you're aware of everything from your mother, I wanted to tell you. I don't know how this next fight is going to end, but I wanted you to hear the truth from me.
Corrin: Thank you, Lilith... I suppose that's one more reason for us to get through this. We need time to bond as sisters rather than just a noble and their retainer.
Lilith: I guess you're right... I'm looking forward to it.
Corrin: But in order for that to happen, we have to defeat our father... Are you with me?
Lilith: I always have been.
Corrin: I'm glad to hear it... In that case, let's go. The end of the war is waiting for us on the other side of this door. Fate has been expecting us for too long, and... I'm ready to face it head on.
Lilith: We're all with you, Corrin. That's a promise.
Corrin: Thank you, Lilith... Let's go.
We've got one more chapter and then it's endgame guys hell yeah
