Alrighty! 😀
They all inherit their positions around the royal family. His S/O was no different. But their line was rendered useless the day the queen died. Their family, while unwaveringly loyal to the king, had always served the queens/princesses of the land. So being without a queen to serve under, they were stuck in a sort of stasis.
Though that didn’t mean they were allowed to slack off on their duties. They were always in training for any potential new queens, taking special care of the queens private chambers. They learned everything they were supposed to, but since there was no queen for their parent to serve, they could live as normal citizens. And when a new queen would be crowned, their parent would step down and they would take their place as the queen’s companion.
Noctis didn’t know who they were when they met in elementary school. He didn’t realize they were of a noble house, much like the Amicitia and Scientia. Not that it mattered, they became the closest of friends anyways.
(I headcanon that the king has his shield and adviser, and the queen has a sword and companion.)
It wasn’t until high school his S/O realized that they had romantic feelings for the prince, but quickly crushed those feelings. They could not allow them to come to light, since they were meant to serve the royal family, and distanced themself from him as a result. Eventually, this distance caused their friendship to become strained and then dissolved.
A few years after they both graduated, it was announced that there would soon be a new queen to serve. Lunafreya Nox Fleuret was to be married to their prince. This was when they were rushed to the palace to start preparation for her arrival.
They run into Noctis, Ignis, Gladio, and Prompto, greeting them briefly and allowing themselves a small time to catch up a little. And much to their horror, they discovered the feelings had not faded.
He’d be surprised to see them there, and as soon as they left he’d ask Ignis about their presence. Imagine his shock when he discovers they basically are meant to be to the queen as Ignis is to him.
The four depart and they are left in the citadel. And they get to briefly meet Luna, along side the person who would become Luna’s sword, and are genuinely looking forward to working for her.
(Luna doesn’t comment on it, but she can feel that both already loved her unconditionally. Which does surprise her.)
But then…Insomnia is plunged into chaos. And falls. They manage to be a part of the escape. But their parents are dead. The sword’s line has ended in defense of the woman would would have been queen. And they are left adrift.
Luna takes them with her, and she does serve as her companion alongside Gentiana. Since it was the last thing they were ordered to do in the name of their family, they weren’t going to let Luna out of their sight.
In Altissia, they wait beside her for Noctis’ arrival. They are fully aware of what will happen to Luna, and have helped her through some of the fatigue she feels from the damage her body is taking to wake the Astrals.
And when Luna requires something be brought to her, they go to get it from the market. Imagine their surprise when they recognize the four boys waving from a gondola.
They wave back and meet them where they gondola docks. They request to meet Luna immediately. But they can’t allow that to happen yet. Per Luna’s request they cannot meet yet. Though they reassure Noctis that Luna does want to see him. It’s just that she needs time to rest before contacting Leviathan.
Gentiana appears before them and relays a message from Luna to them, telling them to guide the boys around Altissia. Gentiana from there takes the items Luna requested and leave them to it.
They spend the whole day together, allowing the boys to relax and enjoy the day. They also catch up and find out Noctis’ thoughts on the marriage to Luna and how he’s content with the match.
Slow dancing at the Maagho to music was one of the highlights of the night. They dance with all of them at least once.
The day allows them to come to terms with their feelings, and this night allows them to say goodbye. Because Luna and Noctis were to be married and honestly, how could they come between them?
They take them to the Leville Hotel to check in and have a moment alone with Noctis on a balcony.
There they say they have something to tell him. They let it all out. They tell him they’ve loved him for a long time, but will never acted on their feelings, and never will now. They can’t look him in the eye as they speak. But they smile as they speak, and stare into the distance.
“Just thought you should know.” They then turn to leave, and are at peace with their choice to let him go. But when he pulls them back and pressed a kiss to their mouth, they feel the world fall away.
He explains as he holds them close, that he had liked them for almost as along, and though he loves Luna, it’s not the same love he feels for them.
They have each other for the night, and if the others see anything, they don’t comment on it. They’ve known that the two cared for each other. Which is why they had been constantly checking with Noctis about the marriage. If he had ever show signs of not wanting it, they would have encouraged him to not go through with it.
They tell him, they’ll love him always, but this night was the only one they could have together. Considering Luna and his impending marriage. they depart reluctantly, but both understand their places.
And then Altissia is evacuated and destroyed when Leviathan is awakened. Luna dies. And they are one of the people listed as missing.
As it turns out, Gentiana has passed the trident onto them to pass on from Luna, and reveals herself as Shiva. They serve under her for a while, fulfilling Luna’s wishes.
They appear on the train with Gentiana, no longer missing, bid her goodbye, and from there on serve as a support to Ignis.
They do not pursue the prince’s affections after he had lost Luna, but they do wait for him. They recognize that he did love Luna, even if it was on strange deeper level than just romance. And eventually, Noctis does reach out for them.
