(The chapter starts with Leo approaching Corrin. The day is almost over and the army is preparing to make camp for the night)
Leo: Corrin, I have bad news.
Corrin: What is it?
Leo: I went looking for Nyx to see if she was ready for our daily meeting, but I can't find her.
Corrin: You can't find her? Where could she be?
Leo: I don't know. I searched everywhere, but I haven't seen her. I heard Iago has gone missing as well.
Corrin: Is it just me, or has she been acting kind of strange lately? Especially when Iago is around.
Leo: I've noticed it too. Ever since we left Nestra, she seems kind of on edge.
Corrin: We should try and talk to her after we find her.
Leo: There's one place I think she might be. Have you heard of the Eternal Stairway?
Corrin: I'm afraid not.
Leo: It's a route into Hoshido. It's not advised for travelers, part of an army or otherwise, since dangerous situations arise there all the time. Some theorize the place may be haunted. I know that's highly improbable, but few have gotten out alive. Nobody ever wants to investigate since it's so risky.
Corrin: Do you think she wandered off and got stuck there?
Leo: It's possible. It isn't too far from where we're making camp. I told Father it wasn't a good idea to be so close, but he refused to listen.
Corrin: Damn... Let's get our troops together. We can leave and search for her. We'll be back before anybody notices.
Leo: Alright. I'm on it.
Corrin: Nyx... Please be okay...
(The scene changes to show the army standing in the Eternal Stairway)
Camilla: Corrin, we've been searching for quite some time, and there's no sign of her.
Corrin: She has to be around here somewhere. Nyx!
Elise: I hope she's okay...
Azura: Wait... Do you hear that?
Xander: Hear what?
Azura: It sounds like growling...
(A large group of Faceless appears)
Corrin: Leo... I think I figured out why the Eternal Stairway is so dangerous.
Leo: Faceless can't form on their own. Someone must have raised them.
?: That would be me.
(Iago teleports in. He is holding Nyx in a choke hold)
Corrin: Nyx!
Nyx: Lord Corrin... I...
Iago: Oh, you were looking for your little tactician, were you? Well, you aren't getting her back. I have a score to settle with her.
Camilla: Iago, I'm warning you...
Iago: King Garon won't let you hurt me, and you know it. You may be his children, but that means nothing to him. I'm his advisor in this war. He wouldn't know or care if you mysteriously died at the hands of Faceless...
Xander: Stand down, Iago!
Iago: Denied. I have unfinished business to take care of. Good luck getting out of here. If you can make it out alive, then we'll talk.
(Iago teleports away)
Corrin: Iago! Get back here!
Elise: There are so many of them!
Azura: Corrin, we have no choice. We have to fight our way through them.
Camilla: They'll overwhelm us soon if we aren't careful.
Corrin: In that case, we must fight. Don't bother routing them. We need to get through these Faceless as quickly as possible to save Nyx!
(After the battle, the royals burst onto the scene where Iago is keeping Nyx)
Xander: I'm glad the other soldiers can finish off the remaining Faceless for us while we take him down...
Leo: Iago, you have no right to refuse an order from the royalty of this kingdom. Stop what you're doing now.
Iago: You don't know who you're dealing with.
Camilla: We know you're a criminal already.
Iago: I'm talking about her. She never explained who she was to you, did she?
Corrin: …
Iago: If she won't say anything, I'll simply have to explain it for you.
Nyx: You had better—
Iago: Quiet!
(Iago throws Nyx to the ground)
Nyx: Ack-!
Corrin: Nyx!
Iago: She's not merely a traveling sorceress. She has royal blood flowing through her veins.
Leo: What are you talking about?
Iago: Long ago, Nestra had three children in line for the throne. There was Augustus, the oldest, Nyala, the middle child, and Ianne, the youngest. Nestra has always been known for its magic. Augustus, of course, had no interest in such petty desires. He ignored the power at his fingertips and let his younger siblings do the heavy lifting.
Corrin: I don't understand. Why is this important?
Iago: Nestra was once a great nation on par with Nohr thanks to its economy. However, that all changed when pathetic Nyala decided to go too deep into magic and destroy everything around her. Countless Nestrans were murdered. Homes were destroyed by her outburst. Survivors in the capital were few... And then she ran away.
Xander: Get to the point faster.
Iago: Ianne dipped into dark magic following his sister's disappearance. He discovered the truth about the darkest powers in all the land... He got it to reside at his very fingertips whenever he needed it. Soon enough, his aging slowed, and he was able to live for over a hundred years.
Camilla: You can't mean...
Iago: Ianne stole the royal treasure of Nestra, a knife gifted to Nestra generations ago by the Nohrian royal line. Spectre. I'm sure you've heard of it, yes?
Xander: Spectre hasn't been seen in over a hundred years.
Iago: I have it in my possession now. My fate as a prince of Nestra is far behind me. I have other business to take care of now. Of course, I never truly got over what happened to my dear people, which is what brings me here today.
Leo: I think I understand...
Iago: Over a century ago, this young woman was born as the second child to the Nestran throne, Nyala. She killed her countrymen and parents after losing control of her magic. Once upon a time, I had faith in the world, but she took it all away. Now, I'm here to get my revenge.
Corrin: Iago, stop this—
Iago: You cannot command me to do anything! I have waited long enough to finish the one who hurt me so many years ago, and I won't let any of you interrupt me! Say farewell to your precious tactician, for it's the last thing you'll ever say to her!
Corrin: Iago, no!
(Iago produces the knife Spectre and stabs Nyx in the stomach with it. He kicks her towards the royals)
Iago: She's as good as finished, just as I am finished here. Farewell, children.
(Iago disappears)
Corrin: Elise! We need you to heal her!
Elise: My staff isn't working fast enough! I need something stronger!
Camilla: Stronger?
Elise: There are supplies back at camp that would help!
Xander: We're too far away. We won't make it in time.
Leo: We have to do something!
Corrin: I'm going to get Lilith. She can help us. She can take us to the Astral Plane! There should be supplies there to save Nyx!
Camilla: We have to hurry. There's no time to lose.
Corrin: Then come on!
(The royals leave with Leo carrying Nyx)
I'm really trying to get this done ASAP
