After stopping at Leirity Seaside and Spelcray Haven, the group makes it to Cape Caem. Iris departs from the party and heads into the house to see Talcott. While the boys spoke with Cindy, (Y/n) wandered off towards the cliffs. She admired the beautiful view of the ocean with the lighthouse at her back. She inhaled deeply, the salty sea breeze bringing her a semblance of peace. The gentle breeze also cooled her heated skin. She stretched her arms towards the sky with a hum of content. "This place really is nice."

Glancing across the surface of the glistening ocean, (Y/n)'s peace of mind was shattered by Callyx. Unconsciously, she raises a hand and presses it against the back of her neck. Her smile was vanquished by a melancholic frown. Although hidden by her clothes, she felt as if she could feel the one thing that connected her to the empire-the barcode. Unlike Prompto, hers was located on the back of her neck. She knew the truth behind his existence, but he didn't. Nor did he know the truth behind hers.

"Hey!"

(Y/n) was startled from her thoughts when she heard Prompto yelling. She turned around and watched him run towards her. "Hey, I thought you'd be with the others."

"Why would I be when my favorite person is missing?" He asked with a smile. She wanted to smile, but her dark thoughts kept her from doing so. Of course, Prompto could tell she wasn't cheerful as usual. "Y'know, frowny faces aren't allowed here. The view is way too beautiful. What's wrong, (Y/n)?"

She looked away from him. "Dark thoughts, that's all. I thought I had managed to push them aside, but they keep resurfacing."

"Are these "dark thoughts" because of Callyx?"

She nodded her head weakly. "Yeah..."

"You listen to me anytime I need to talk and always know how to cheer me up. Whenever I needed a shoulder to cry on, you were there. You're the reason I've come this far and think I'm actually a worthy person and not just some waste of space. I just want to let you know I'm here for you just like you are for me, and I'm not going anywhere, okay?" Prompto reaches out and takes her hand in his, squeezing it gently.

(Y/n) could feel the sting of tears forming from his kindness. She bit her bottom lip to keep the tears at bay. She couldn't even bring herself to look at him in fear she'd begin crying. All she could do was squeeze his hand in return. "Thank you, Prompto, but I'm afraid this is something I can't share with you just yet."

Prompto didn't want to force her to do anything and respected her decision. "Well, when you're ready, I'll be here."

The guardian inhaled a shaky breath. She managed to turn and look at him, but the thing she was trying to not do happens. The tears she's been holding back spring free and cascade down her cheeks. Before she could even attempt to wipe them away, Prompto was already on it. His hands cradled her cheeks, using his thumbs to wipe away the tears. He was taken aback at her sudden tears and couldn't help but worry. "H-Hey, it's okay. Please don't cry, (Y/n)."

"I'm sorry, Prom," she sniffled.

"Don't apologize, silly." Prompto presses his forehead against hers with a warm smile. He wipes her tears away for a little longer before slipping his arms around her smaller frame and hugging her gently. She didn't hesitate to reciprocate the hug and wrap her arms around his torso. They remained in each other's arms until they heard Noctis shouting their names. Prompto pecked her on the forehead before grabbing her hand and rejoining Noctis and the others.

Once back with the others, Ignis explained how they learned where to find the mythril to repair the boat from Talcott. Their next destination would be the Vesperpool. As they were about to make their way into the house, Gladio stopped them. "So yeah, gonna have to ask you to handle this boat business without me."

Prompto gaped in shock. "Say wha?"

"Got some business of my own to deal with," the shield vaguely responded.

Noctis knew Gladio all too well and didn't try to change his mind. "Do your thing. Not like we could stop you anyway."

"You know me too well." He walked past the three boys and came to a stop beside (Y/n). He patted her on the shoulder. "Keep these guys in shape while I'm gone, short stuff."

She smirked in amusement. "You can count on me. Take care of yourself, Gladio."

"Don't have to tell me twice. See ya 'round." With that, the shield left.

<-------------<<<<<

Several days later, everyone minus Gladio was in the Regalia. Noctis was driving, Prompto was in the passenger's seat, and Ignis and (Y/n) were sitting in the backseat. The strategist recognized their surroundings from their earlier expedition in the area. "The waterfall cave was right around here."

"That means the lake should be somewhere north of here," Prompto said.

"Be wary, though-where we go, the empire seems to follow."

"Which means we might see Callyx again..." The marksman muttered with a slightly angry undertone.

"You hate the guy that much?" Noctis asked.

"Yeah, I do!" Prompto sat up in his seat with a huff of annoyance. "He hurt my beautiful goddess!"

(Y/n) chuckled slightly at his reasoning. "Trust me, I made sure he felt some pain before I left."

Eventually, they pull up to a tunnel whose gate had previously been locked. It opens and allows them passage. Prompto was puzzled at the entire thing. "Wait-what happened to "under imperial lockdown"?"

"They all but turned the key and left the gates open for us-as if awaiting our arrival," Ignis commented.

"And if anyone's waiting for us, I bet it's those guys," the sharpshooter grumbled.

"Chancellor Izunia and Callyx."

"Can't complain as long as they let us in," Noctis said.

"Who's to say they'll let us out? Not to mention we're a man down. Would that the marshal were with us," the advisor stated.

"But we have (Y/n) now!" Prompto chanted. "And whatever happened to that guy?"

"As I understand it, he's put his tomb raiding on hold to help the hunters take care of some troublesome beasts."

"No rest for "the immortal"," the prince said.

(Y/n) was curious to ask about Cor since she's only heard a few things about him from Prompto, but her train of thought was derailed when Noctis slammed on brakes. She braced herself as the car swerved from the harsh braking, her nails digging into the leather of the seat. Wondering why he made a harsh stop, she looked up to see an imperial blockade consisting of an MA Veles and imperial troopers.

"No way through," Noctis mumbled.

"So they give us access to the Vesperpool, but still intend to stop us by setting up other blockades," (Y/n) stated as she got out of the car.

"Yeah, it totally doesn't make any sense," Prompto commented. "But what do you expect from the empire?"

"Good point," Noctis said.

Once everyone was out of the car, they summoned their weapons. Ignis, wielding his daggers, warned his companions. "We must be doubly cautious."

"Right. No Gladio, no room for error."

Even without Gladio's presence, the battle went smoothly. They were able to easily dispose of the imperial forces and continue down the road. This time, Ignis was behind the wheel. Noctis, even with (Y/n) in the backseat with him, was able to spread out. "I could get used to havin' all this room back here. Too bad Gladio isn't as small as (Y/n)."

"It is quite cozy back here without him," the guardian said, stretching her arms into the air as her (h/c) locks were tousled by the wind.

Prompto glanced into the backseat at his best friend and girlfriend. "I'll let the big guy know you guys said so."

After a few more minutes of driving, Ignis parks the Regalia near the Vesperpool. Everyone exits the vehicle and heads into the nearby swampland in search of the ruins they heard about from Talcott. Down the trail, they spotted two familiar cars. One was red and the other was black.

"Oh, great..." (Y/n) groaned.

As they come near the ruins, they find Ardyn and Callyx waiting for them. The female spirit smirked in satisfaction seeing her fellow guardian's right eye was foggy. The skin around it was pink and puffy from where she burnt him. The boys also noticed the man's maimed eye. Prompto leant over and whispered to the golden-eyed spirit. "You did that to him?"

"Yeah. He deserved it," (Y/n) replied.

"Damn..." Noctis mumbled at seeing the damage.

Ardyn addressed the group as they made their way over to him and Callyx. "Gentlemen." He then took off his hat and bowed in (Y/n)'s direction. "And lady. What a pleasant surprise."

Prompto glanced between the two men with a groan. "Ugh! Told you they'd be waiting!"

"With my imperial friends, no less."

"Splendid," Ignis rhetorically retorted.

The chancellor quickly tried to assuage their concern. "But fear not-I'll put in a good word. Well, come along, then." He turns and begins walking toward the ruins. Callyx, on the other hand, didn't budge. He glared at the girl with his only remaining eye. He took a few steps towards her, but was stopped by Ardyn. "Do behave yourself, dear friend."

Callyx gritted his teeth, clenching his fists tightly. "If I could, I'd rip into your flesh again, right here and right now."

(Y/n) wasn't afraid of the man and stood her ground. "Did you not learn your lesson the first time? Guess you didn't and now don't wanna keep your left eye. I don't mind burning it like I did your right one."

"Why you little-!"

"Callyx," Ardyn gently called out in warning.

The male guardian reluctantly backed away with a snarl. He turned his back to his fellow spirit and followed after the chancellor.

Ardyn smiled at the group as Callyx took the lead towards the ruins. "I do apologize for his unruly behavior." He adjusted his hat and walked alongside his spiky-haired companion. "Now then, don't stray too far, lest you get left behind. And surely you'd rather avoid unnecessary scuffles, seeing as you're now a quartet. Oh, dear. Touchy subject?"

"One we won't discuss with you," Ignis quipped rather harshly.

"Then let's discuss why you're here. Hmm.... It can't be archaeology... Mythril, perhaps?"

"This guy's reading our thoughts!" Prompto gasped.

"Mythril-it's a precious resource. We can't just let anyone get their hands on it," Ardyn claimed.

"But you'll help us get ours on it, right?" Noctis asked.

"I never said that!"

"Of course you didn't," Prompto muttered.

"Where is the fun in that?" The chancellor questioned. "I thought you'd rather dig it up yourselves."

"We'll make you all do the damned dirty work yourselves. You're capable enough even with one person missing," Callyx sneered.

(Y/n) couldn't hold her snarky remark at bay. "Oh, so you won't dirty your hands for mythril, but you're fine with killing your own people. Nice to know."

"You're making it very difficult to not kill you," Callyx growled.

"You won't because your tail wags for your master."

"So does yours," he retorts.

"But mine doesn't keep me on a short leash and actually trusts me."

Callyx's self control shattered. He reached out to grab the girl, but his arm was grabbed by her and she twisted his arm behind his back. Using her foot, she kicked the bend of one of his legs and forced him to a single knee. He grunted in pain as he struggled against her, but his current position made it difficult.

The guardians' argument didn't go unnoticed. The boys and Ardyn had watched the entire thing unfold. The chancellor was smirking in amusement while the others were shocked. The auburn-haired man strolled over with a chuckle. "As I believe this is a suiting punishment for Callyx, I do beg of you to release him, my dear. His punishment will come at a later date, I assure you."

(Y/n) glared at the chancellor before releasing Callyx. The male spirit got to his feet, rolling his shoulder and trying to ease the pain. "Damn you..."

She crossed her arms with a victorious grin. "Run along, kitty. Your master's tugging on your leash."

Without another word, Callyx walked away. Prompto watched the emerald-eyed guardian stalk away, clearly consumed by anger. He then looked over at his spirit with an astonished expression. "Wow, (Y/n). I've never seen you so angry before."

"I'm not someone who usually is easily angered," she sighed. "But Callyx just grinds my gears. Knowing he's willingly working for the empire and killing our people is what irks me the most."

"By that display, I do believe we won't be needing Gladio's assistance for this endeavor," Ignis said.

Noctis glanced at Callyx's retreating form before looking over at the golden-eyed girl. "I thought you were gonna break his arm."

"Oh, trust me, I wanted to. I already broke it once, but I'll gladly do it again," she responded. "Guardians are more resilient than humans and our injuries heal quicker, but it seems Callyx is still experiencing issues with his arm after I broke it at the fort."

"Indeed, he is," Ardyn sighed. "You did quite a number on him, my dear. The poor man was brought back to me with his eye singed and arm shattered."

"And you're not mad?" She inquired.

"Of course not. Callyx fought and lost. Tis a mere outcome of battle."

Hearing Ardyn's confession, (Y/n) felt a tinge of sorrow for Callyx. The chancellor wasn't saddened if the man was injured in battle. He doesn't care for him like Prompto does her. She shook her head, ridding herself of the thoughts. "Putting all this aside, aren't we here for mythril?"

He tipped his hat with a faint smile. "Right this way."

They continued to follow Ardyn down the trail until they reached the ruins. Outside the entrance to the ancient structure stood the woman they had fought against at Fort Vaullery. Beside her were two imperial officers.

Ardyn turns to Noctis and the others. "Fear not-I'll be but a moment." He walks over to the woman and begins to speak with her.

Prompto looked over at his best friend. "A moment doing what?"

Noctis shrugged his shoulders. "Beats me."

(Y/n) looked around at the number of imperials were stationed in the area. She could feel their eyes on her as their grips on their weapons tightened. She grimaced at the unsafe feeling she was experiencing. She was the conduit, the spirit the empire was seeking to kill. Now she was standing in the middle of an imperial hornet nest, afraid she'd stir the insects and wind up dead. "I'm not so sure I should be here..."

The prince glared at the imperial troopers who were eyeing the spirit. "Nah, it's fine. If they really wanted to kill you, I'm pretty sure they'd already done it."

"Perhaps the chancellor is the reason they remain inactive," Ignis speculated.

She rubbed her hands up and down her arms. "I just hope we get this mythril as quick as possible..."

Just then, Ardyn calls out to them. "All clear! Go ahead."

The group approaches the woman, who was eyeing them closely. "So, you're the "new recruits" they sent over for "special training." Nice cover, runaway prince."

"Thanks," Prompto replied.

Noctis groaned at how casual the blonde was being. "Oh, c'mon!"

The woman shook her head with a sigh. "At ease, "recruits." There's nothing in it for this ex-mercenary to turn you in."

"Well that's a surprise," (Y/n) muttered.

This caught the ex-mercenary's attention. "Good thing because your name and the prince's are on the empire's list. The very top, I might add." She took a few steps towards the girl and examined her appearance. "But I know I'm already gonna like you, firefly."

The guardian blinked in surprise. "Why's that?"

"You're the one who fried Callyx's eye. If you hadn't done it, I would've. Bastard's been a thorn in my side for a while now." She patted her on the shoulder, grinning. "I look forward to working with you, firefly."

(Y/n) glances up at the sky, noticing the sun was beginning to set. "Then let's get this show on the road."

Her grinned widened. "Took the words right out of my mouth. Let's get moving, "recruits"."

Seeing the group had become acquainted with the ex-mercenary, Ardyn chimed in. "I trust you'll be civil. Commodore Aranea Highwind, I leave them to you."

Aranea puts on her helmet and guides the group towards the entrance of the ruins. As they trudged through the shallow water, Prompto noticed the strange design of the ruins. "What kind of place was this? Any idea, Ignis?"

Ignis was also intrigued by the ancient structure, but he had no answers for the blonde. "None."

"Gee, I wonder what happened to the locals."

"Why not head inside and look for 'em?" Aranea suggested.

"I'm not so sure if we want to find the locals," (Y/n) said. "Who knows if they're hostile or peaceful."

"Guess we'll figure out the hard way if there are any locals," Noctis spoke up.

When the sun set behind the horizon and the moon rose into the sky, the entrance to Steyliff Grove was open. As they entered the ruins, (Y/n) took note of the design. She ran a hand across the wall. "Hey, Prom. Don't these ruins look a lot like the ones we hid in a while back?"

Prompto also analyzed the structure of the ruins. His eyes widen when he too saw the similarities. "Oh, yeah!"

"You must be talking about Costlemark Tower," Aranea voiced. "Place is crawling with daemons and has the same strange mechanism that prevents anyone from entering during the day."

The marksman glanced over at the ex-mercenary. "Does that mean this place is gonna be crawling with daemons too?"

"Most likely."

"Oh, yay..."
