"Nnnnghhh..." A voice moaned in her sleep, tossing and turning as the blanket slung over her head and the blinds concealed the piercing light of the sun on this beautiful day. Underneath the covers was a girl around her teenage years, a head of crimson-red hair like Cordelia's and a beauty unsurpassed by many girls her age. Although her physical attraction was obvious, her temperament was an entirely different story.
This is Cordelia's daughter, Severa.
Severa is the youngest of the time-traveling children. Although it's established that her mother is Cordelia, she had no idea who her father was and didn't bother to ask. Apparently he had died shortly after she was born, and very little mention was actually made of him by Cordelia, at least Severa thought. Therefore, the girl didn't feel the need to try and understand it. She had a mother and that was it. A loving mother, yes... but one that Severa felt she lived entirely in the shadow of.
When she was still young, she knew of the reputation of her mother. She was often regarded as a hero, a fierce warrior, an intelligent and attractive young woman, and an inspiration to all around her. Naturally, such expectations would weigh heavily on the shoulders of the woman's child, Severa being constantly reminded all the time about how special she was and how she had such potential being the daughter of the revered Cordelia. Did this make the girl feel any good or feel any sort of individuality? Did having such a "revered and accomplished" woman as her mother reflect on her abilities? Absolutely not. Severa knew that she could never live up to the extremely high expectations of her mother, and due to this grew an inferiority complex. Along with that, her attitude soured, annoyed that she was just living in another person's shadow.
Although she did feel strong resentment towards this fact, she still cared for her mother greatly. She wanted her to be with her all the time, but unfortunately because of her duties as a Pegasus Flier (and more than likely due to her unrequited love for Chrom), Severa couldn't spend all that much time. This eventually led the young girl to snap, turning her frustrations on her mother. In response, Cordelia said that the only thing she'd ever fight for was for a better future for her.
That was the last time Severa saw her when she was young.
Cordelia was killed in battle defending Chrom. Upon hearing the news, Severa left in heartbreak and became a wanderer. She used whatever fighting skills she had in her arsenal to become a mercenary, and a pretty damn strong one, too. She'd bounce between towns and villages, keeping her name to herself and opening up very little to anyone she encountered. She eventually met some interesting characters along her journey, including the blue-haired daughter of a deceased king. And before she knew it, she was in a completely different time period with these characters and many others.
The girl ended up seeing her mother again, one part extremely happy and the other part bitter (though this was mostly a facade). Although she had opportunities to talk with her in the barracks, the girl still wasn't quite ready for opening up to the woman about her past and her relationship with her. There were still some things that could be done to strengthen their bond as a mother and daughter...
...and Severa squandered a chance today. In all likelihood, the girl would have asked her mother if she could have the opportunity to train with her one-on-one. Instead, the girl took it upon herself to go out in the middle of the night to do her own personal training. She did so intensely for hours on end until the very crack of dawn, proceeding to remove her armor, clean up, return home, and collapse right into bed, where she had been sleeping for the majority of the day.
