"For all of the masses of Fontaine to view tragedy as audiences in a play rather than humans with empathy, for even the almighty gods seemingly watching on in apathy, it seemed that the Hydro Dragon was the only one to cry for me that day. Thank you."

Édelie Romaria, born from the prestigious Romaria Clan, was a young noble lady who grew up without much suffering other than what the usual nobles would go through. Though she knew there were some secrets and affairs that her family hid from her, she bowed her head and instead focused on her younger sister, Arturia. The once large and prosperous noble elites had all but died off, leaving her small family as the last remaining members.

On a nondescript day, everyone was awoken to Édelie defending her sister from a rogue hilichurl that happened to cross their usually guarded gates. Arturia was gravely injured and was immediately sent to Mondstadt in order to ask the Church of Favonius to help heal her. Though she had fought tooth and nail, surprisingly, Édelie did not get injured as much. While people around her were praising her for her noble actions, her family seemed worried and agitated, as if she had done something she was not supposed to. On more than one occasion, she had been chastised not to do such reckless things and to keep a low down and be modest. She doesn't understand what made them fear for her but still, she quietly accepted it.

It wasn't until after once again, she had seen injustice and fought for it that she had realized she wished that she could continuously protect what's important to her from all the unfairness of this world. There, she was blessed with a Vision, as it attracted the wonder and awe of many, and the fear of her family. She was immediately sent home and her parents begged her to hide, to never agree to whatever being would ask of her, that it is better to die than to be chained up. There, Édelie felt a burning hot pain go over her body, her Vision seized from her control and a loud mocking voice echoing in her brain. She remembered watching, but not really being there at all, just seeing a man their family had known and her parents begging. The man, with bulging otherworldly eyes stared at each member of her pitiful family before he struck them down in cold blood. When he was done, he turned to face her as she stared him down, fear and helplessness from the pain and being seizing her from moving. She heard it ask her if she wanted to live and against all odds and what her parents asked of her, she said yes. The Oath settled onto her Vision as the Mad God's glee and laughter echoed in her head. The man whom she would later realize was Fontaine's Watcher, looked at her with pitying eyes. He gave her some parting words before he left her.

Later on, she would meet a lady who would clarify and teach her all she needed to know about what she has gotten herself into. As with her other apprentice, she was bestowed the name "Soleil" in order to shine light to those who cannot do so. At the same time, she met two boys whom she formed some sort of solidarity with as she promised to take down Fontaine's Watcher and claim the title for her own in order to protect the justice that seemed to lack in a nation that claimed to be one.

"A pity, truly, but under the Mad God's influence, we can only open our eyes and gaze on in contempt. Make it a goal, young lady, to go against this flow, to rebel, and perhaps... To take me down and judge me with your own sense of Justice."

During her years as a Seeker-Apprentice, Soleil was part of what will one day soon be dubbed as the legendary Three Pillars of the Collective, along with Zivon and Yuè. Her role during this time was simply as the mediator between the ever constant bouts of fighting between the two muscle-heads. Still despite how she claimed to be the weakest link, she is far stronger and much more versatile than any of her potential coherts during that time. Though it wasn't as spartan nor as easy-going as Yuè's and Zivon's own attempt at training apprentices later on, Soleil's time was neither pushed to the limits nor was her training too lax. If anything, it was Yuè's insane yet extraordinary training methods that she was pulled into that had increased her abilities and skills. The way the three had balanced each other out had pretty much evolved their somewhat calm lifestyle into what would become true geniuses that would spear-head the Second Rebellion.

She is the first among the three to be promoted as a Watcher as one day, she had finally found the courage and the correct time to confront the former Watcher of Fontaine and her family's murderer. Throughout her apprenticeship, she had learned certain rules bound to being a Watcher, including those of her own nation. The Oratrice will never judge her position fairly, as she must weigh sacrifices needed to give to the Mad God, something that no human must do. Thus, she was taught to never be found on the opposing end of someone's finger, lest she must instead end everything with a duel instead. Knowing that, Soleil had finally decided to charge Fontaine's former Watcher with the murder of her family, causing an uproar within the nation. As Neuvillette himself had promised to see things through, he was ready to judge the criminal only for him to request for a duel. As Clorinde was about to accept, Soleil herself requests to be the one to duel him, to judge him with her own beliefs of Justice. The duel was approved, and thus her final ascension began.

The duel ended with Soleil winning with just her blade, as she did not want any of her dolls to be tainted and to dirty themselves with her sins. She felt her Vision-Gaze shifted, finally unlocking her full potential and no longer worrying about the pain that comes with a backlash upon using it. Later on in a small get-together party with Zivon and Yuè, they mention how she's finally moving up and breaking away from them to which she simply scoffed, knowing that they're both due to a promotion as well. With the clinking of glass under the pale moonlight, Soleil began her first job as Fontaine's new Watcher and immediately resigned and handed the job of being the Romaria Charity Fund's President to Arturia while she takes her new position and job as Neuvillette's Secretary and Assistant.

The unfortunate side-effect of her handing her position to Arturia had made the lady question her goals and her intentions, starting a fight between the two and hereby enstranging them. Soleil knew it was for the best, to lessen the people that will be hurt when the inevitable time of her betrayal would come to light but she does question why Arturia had decided to storm the Fortress of Meropide and establish her base of operations there instead. Still, she wished her for the best, asking Neuvillette to seek Wriothesley's assistance to help in monitoring and keeping her sister safe. Though years later when she found out about their ever blooming relationship, she couldn't help but regret doing that somehow.

"So one day, you better invite us to that promised wedding of yours or you'll never stop being an Old Hag! What? Am I wrong? Whoever you marry isn't my problem, but isn't it better to have a promise of a future than the despair of the past?"

Yuè's death had been a blow to all of them, more so especially towards Zivon and Soleil. He had been the strongest and the one that had carried the most burden, so his death had tremendous side effects towards the first few years. Despite that, life had moved on and she had learned to adapt. Though Zivon had focused on poking and prodding what was left of Yuè's former apprentices (now fellow Watchers), Soleil had kept herself distant, no longer wanting them or her to feel whatever loss she had felt upon her friend's demise. Even more so, seeing the face of his supposed killer and his proudest achievements would tear away whatever heart remained for the Collective.

Soleil's true ability lay in her swordsmanship, though she has rarely taken up the blade after her final duel against Fontaine's former Watcher. She had come to rely on her catalyst more, sometimes her dolls that she treat as her children. Though it is precisely why she refused to fight nowadays, as her doll constructs would find themselves fighting eagerly more than necessary and she usually ended up cleaning after them. Nowadays, the dolls are mostly there to keep her and Neuvillette company, acting more as cheerleaders and mascots more than fighting (though this does not stop them from ocassionally finding certain monsters to beat up on their own). Perhaps everything had gone stagnant and calm after Yuè's death, perhaps she and Zivon had lost their way as the supposed final Two Pillars holding the Collective together. Either way, things had remained calm up until a certain Traveler was reported by Skye to all of them.

Though she knew the kind of variable he is was dangerous and unpredictable, perhaps he could be someone who would ruin all of their carefully built up plans. However, as someone who was used to all of Yuè's unpredictable schemes, she figured it would be a shame if she didn't actually try to place such a good chess piece towards their side. Thus, began Soleil's careful steering of the Traveler to their cause, dropping hints of something being off yet never enough to form a concrete idea.

Upon the Traveler's journey, this marks the start of the mad god's activity to increase as well, forcing the Watchers to finally fight head-on and plan for the final sealing and their second rebellion. Nothing is certain but one key fact is that the Watchers are at eye of the storm.
