Ignis was driving the Regalia towards Lestallum after they stopped to do Prompto's photo op. Along the way, the could see the Meteor of the Six.

Prompto: Oh! I know that! That's the old Meteor!

Ignis: It is, and it's still burning to this day.

Gladiolus: Powering all of Lestallum in the process.

Prompto: Really?

Y/N: It's not like the Crystal and the Crown City.

Noctis: Suppose that makes sense.

They then drive through the now open Lestallum Blockade, heading across a bridge that led straight into a tunnel, which led to the city of Lestallu

Gladiolus: Was pretty cool to see the Meteor for ourselves.

Prompto: Yeah, it was on FIRE!

Noctis: Surprised Titan's hands don't burn up.

Y/N: Isn't Titan a god?

Prompto: Wait, I thought that was just a fairy tale.

Ignis: Tales of the Six fighting alongside Lucian Kings date back to the age of gods.

Prompto: For real?

Noctis: For real.

Gladiolus: And yet somehow, I find it hard to believe.

Ignis: Not all kings are created equal.

Noctis: Yeah, laugh it up.

They head inside the tunnel, Ignis activating the convertible function of the car.

Prompto: It's like we're warping to another dimension!

Noctis: Wonder where we'll end up.

Exiting the tunnel, they got a clear view of the city. Their eyes widen as they look in awe.

Prompto: Wow!

Gladiolus: Nice.

Noctis: This place is pretty big.

Gladiolus: Haven't enjoyed the city life in a while.

Y/N: Gladio! There's a cup noodle truck!

Gladiolus: No way!

Prompto: They've even have a cable car!

Ignis: I'd like to see where it leads.

Ignis pulls into the parking lot, backing up into it as he parks the car, the group getting out to stretch.

Noctis: (sigh) It's getting hot out here.

Gladiolus: Just need to pull in somewhere cool.

Y/N: And maybe lose the jackets...

Noctis: Yeah.

Prompto: Any chance of sleeping in a nice room tonight?

Ignis: Yes. I'm certain we can secure...suitable accommodations nearby.

Y/N: So long it's within our budget.

Before heading off to the hotel to meet up with Iris, the other three members of the party had to wait as Y/N and Gladiolus had went off to buy cup noodles from the truck it was being sold at.

Quickly putting it back in the car, they set off for the hotel.

Prompto: One hell of a crowd.

Ignis: This must be the main thoroughfare.

Gladiolus: (pulls out phone) She's at the Leville. Let's go.

Walking through the area, they could hear one of the radio's one. It was telling their victory of the Deadeye, which sure pleased the people and farmers around that area.

Prompto continued to ogle at the various foot stands that stood around. Y/N was wondering if there was a weapon shop and Ignis wanted to head to the market to restock on some of their supplies. As they drew near the Leville, Noctis stopped. Titan was calling out to him, causing the Crown Prince to clutch his head in pain.

Since Titan was calling out to him, the ground shook.

Prompto: Whoa, did you feel that?

Gladiolus: You mean the earthquake?

Y/N: You weren't the only one. 

Noctis: (groans in slight pain)

Ignis: What's wrong?

Y/N: You alright, Noct?

Noctis: My head just started throbbing.

Prompto: You alright?

Noctis: Yeah, I'm fine.

Gladiolus: So when the ground shakes, your head aches?

Noctis: Yeah.

Ignis: A sort of seismic shock to the system. Curious.

Y/N: Why do I have a feeling it's not that?

With Noctis's little problem settled, the went inside the Leville.

Soon, they see a fifteen-year old girl running down the steps. She had brown hair and reddish-brown eyes like Gladiolus. This is Iris Amicitia, Gladiolus's younger sister.

Iris: Gladdy!

Gladiolus: Iris!

Iris: Look at you guys, holding your own out there.

Prompto: (chuckles) What can I say? You look good.

Iris: All things considered. You guys are staying here, right?

Ignis: That's the plan.

Gladiolus: When you have time, we have some catching up to do.

Iris: Sure.

Y/N: (sigh) Must be nice to have siblings.

Timeskip-Night

Paying for some rooms, they entered. They soon met up with one of the Amicitia's retainer back in the Crown City, Jared along with his grandson, Talcott.

Gladiolus: Jared and Talcott! Is it good to see you.

Talcott: Prince Noctis! Iris is safe with me!

Jared: Please excuse my grandson. He has yet to learn his manners.

Y/N: Eh. Youngsters these days need to be more free.

Noctis: Heh. I like it.

Jared: (bows slightly) Your Highness is very kind, but we shan't impose.

Talcott: A very good night to you, Your Highness. (bows)

The two leave and Iris closes the door. Noctis settles on one of the chairs, Y/N leaning up against the wall, Ignis sitting on the bed, Iris and Prompto sitting on the other chairs, and Gladiolus remains standing.

Noctis: So Iris, what was it like inside the Crown City?

Iris: Not pretty. The Citadel took a beating. But a lot of outlying neighborhoods made it through in one piece.

Ignis: The empire had tactical targets in mind.

Iris: You know if there's anything else, you can ask me.

Noctis: Yeah, uh, thanks.

Y/N: (mutters) Yeesh. When were you so bad with women.

Noctis: ...Uh, what?

Iris: So...about Lady Lunafreya. I keep hearing she was in town. Apparently she left right away, but at least it means she's okay.

Y/N: I imagine she's going all over Eos, helping as many people as she can.

Noctis: (sigh of relief) Good to hear. Thanks.

Iris: Yeah, well. Get a good night's rest.

With the day ending, Iris leaves the room, leaving the Crownsguard members and their liege to do what they needed to do.

Ignis was fixing up their dinner, and making a dessert that Noctis's hadn't had in awhile. Prompto, Noctis, and Gladiolus were playing King's Knight while Y/N was doing maintenance on the group's weapons.

After dinner, they settled in, Noctis and Prompto sharing a bed and Ignis and Gladiolus taking the other. Y/N slept on the couch as he somehow found more comfort there.

It was the next morning and Iris met up with Noctis in the lobby.

Iris: Morning, sleepyhead!

Noctis: Mornin'. Where is everyone?

Iris: Oh, they're out walking with Talcott. They went to see the sights. We should, too!

Noctis: Sure, why not?

Iris: Great! I'll show you around!

Jared: It seems you patience was rewarded. Enjoy your walk, and please take care.

Iris: For our first stop, we'll check out the marketplace. Follow me, right this way.

The two leave the hotel, taking a stroll throughout the city. The first stop, marketplace.

Iris: (sigh of relief) It's even more beautiful out here at night.

Upon arrival, Noctis and Iris could see the various stands here. Different produce and other items were being sold here.

Iris: This is the Partellum Market. You can get almost anything here. Isn't it great? I'd buy out the whole place if I could.

Noctis: (uninterested) Really. That's nice.

Iris: Could you at least pretend to be excited?

They wander around the market, browsing through the various items that were being displayed.

Iris: Wow! Look at all this neat stuff! I'm gonna take a look, gimme just a sec.

She browses through the items, taking a look at them. With a satisfying nod, she turns back to Noctis.

Iris: Done! Next, we're gonna see the power plant. 

They continue walking the alleyways before emerging out of one to come face to face with the power plant.

Iris: That's the power plant, the driving force behind Lestallum's prosperity. But get this, only women work here. As a matter of fact, women are the only ones who do all the work in this town.

Noctis: (small smile) Sounds like your kind of place. I can see you doing well here.

Iris: (smiles back) I think so, too! It's so different from home, I was surprised at first. But I like it! Alright! Next, we're going to the outlook!

The two then begin to walk to the outlook, the area the Regalia was parked near with the outlook overlooking a cliff.

Iris: I'm a city girl, but I dig the rustic charm. And you would totally love the drinks in this place!

Noctis: Would I?

Heading down the main steps, they soon reach the outlook.

Iris: Peggiar Outlook. Amazing view, right? Look, there's the Meteor! Y'know, Noct, this almost feels like a date.

Noctis: If it were, your brother would kick my ass.

Iris: (giggles) We better keep it quiet, then. And besides, you already have Lady Lunafreya. The others are probably back at the hotel by now. Let's join them.

They return to the Leville, joining back up with Noctis's Crownsguard.

Iris: I haven't had fun like this since we were kids. Thanks, Noct.

Noctis: (smiles) No sweat. I had fun, too.

Iris: (giggles in disbelief) You did? I'm so happy to hear that. Anyway, the thing I bought today...it's for you. But it's a surprise, so you're gonna have to wait.

They walk inside and see everyone else there.

Prompto: Hey, look who's back! Talcott, go on and tell 'em what you told me.

Talcott: You got it!

Jared: Oh, come now, show some respect.

Prompto: Whoa, no need to respect me--I'm not royalty.

Talcott: So, there's this legend about a sword. And the sword's supposed to be behind a waterfall nearby.

Ignis: It may well be one of the lost tombs.

Y/N: Somethin' for your Armiger, eh?

Gladiolus: Check it out?

Noctis: For sure. Thanks for the tip, Talcott.

Talcott: You're welcome!

Returning back to the car, Y/N sat in the driver's seat as Ignis asked him to drive.

Prompto: Folk here are real friendly.

Noctis: Yeah, everybody greets you. Takes some getting used too.

Y/N: To be fair, you grew up in the hands of royalty, Noct.

Prompto: You draw more attention here than you do at home.

Y/N: I know right? The only attention he drew from high school were the ogling from girls.

Noctis: Don't remind me.

Driving towards their destination, Y/N went above the speed limit as there were no other car on the road.

It then begins to rain.

Prompto: My hair's getting wet! Put the top up!

Y/N: Oh, calm down you big baby.

They arrive at a gas station and they pull over. Getting out of the car, Y/N and Ignis grab potions and other items, as much as they can carry, for their mission to explore the cave and get to the next royal arms.

Y/N does a quick refill of the Regalia and said he would catch up. After refilling the Regalia, Y/N goes down the steps that went down to the base of the bridge. He looks ahead to see Noctis and the others fighting a giant snake. It was called, Midgarsomr.

Noctis: Prompto, you're up! 

Loading his gun, he fires the revolver, doing damage as it disappear out of his hands and appears in Noctis's, firing his own shot. Ignis was handing out potions and supporting the others to keep them in top shape.

Noctis: Y/N, you're turn!

Summoning his katana and gets into a stance, he imbues fire into the blade, dashing forward as he slashes the giant snake, cutting it and dealing flame damage. Noctis follows up with attack, teleporting forward from behind Y/N as he strikes it a few times with his Engine Blade. After landing, Noctis takes out a polearm, it's long handle great for attacking at a certain distance. After striking a few times, he calls out to Gladiolus.

Noctis: Gladio!

Using a new Glaive Art, Downhammer, he summons his two-handed sword, preparing to leap. He leaps into the air, slamming his sword down, shattering and breaking the ground below from where his sword struck.

His two-handed sword disappeared out of his hands, appearing in Noctis's as he takes the giant sword as well, slamming it onto the snake. Now vulnerable, they initiate a cross-chain, all five of them attacking in sync, taking turns to get their turn in. With the final hit, Noctis leaps back, the Axe of the Conqueror in his hand and the others drawing their weapons. Y/N and the others rush forward, dealing their damage before Noctis rushes forward with the royal arm in his hand. The battle ends with them taking the spoils, Gladiolus taking the scales off the snake so they can sell it and make some money off it back in Lestallum.

With a foe taken down, the group head for the waterfall.

Prompto: The legend says to look behind the waterfall.

Ignis: What does the waterfall say?

Prompto: I think it says, "Come in."

Y/N: Sure it does.

Gladiolus: Alright, enough fooling around.

With a set goal for the day, Noctis and his entourage enter the waterfall, going inside to collect the next royal arm. The Swords of the Clever.
