It's a pleasure doing business with you!" Should Corrin gain 5 hearts (1 big heart) in the "My Room" interactions with Selena (requires at least A-Support), instead of the normal dialogue, Selena will reveal that her real name is "Severa," a fact unknown to even Camilla. Selena becomes a subordinate of Princess Camilla, though her birthplace and personal history are unknown to the people of Nohr. Some time after the events of Awakening, Severa appears, alongside Inigo and Owain, in the world of Fates and joins the Nohr army under the alias "Selena". Severa shows great skill and promise but denies that she joined because of her mother's legacy. Half a year later after Grima's demise, Severa, along with Cynthia, revives the Pegasus Knight Squad. As Grima is about to finish off the children, the Shepherds sent by Naga warp into the field to protect the children and defeat Grima. Inspired by her bravery and willingness to die, Laurent and Gerome step in to assist in protecting Lucina. Severely weakened by Grima's attack, Severa tells Lucina to escape and go to Mount Prism to perform the Awakening while she stands between Grima and Lucina as her human shield. Grima suddenly appears, taunting the group and demanding the return of the Emblem. In an alternate timeline, Severa arrives in Ylisstol with Gerome and Laurent to hand over the recovered Fire Emblem and one of the Jewels to Lucina while waiting for the remaining children to arrive. Her father consoles her and she makes him vow never to die again.

In the final support Severa feels inferior to her mother because she cannot do any of the chores correctly such as sharpening swords or cooking and feels like she has let her father down. Upon her next attempt her father makes her work for it by doing chores. In her support with her father, she cons her father into taking her shopping and buys way too much.

In the end, the two vow to never part again from each other. However despite Severa's cold attitude to her mother, she wanted to spend time with her all along, but was worried that if she got too close, and her mother died again, she would go through even greater pain. Severa reveals that she became a Mercenary rather than a Pegasus Knight so that people will not compare her to her mother as much. In her support with her mother, Cordelia tries to get to know her daughter. In the epilogue, if she is not married, Severa leaves on a journey, but occasionally returns to her parent's home to yell at them for "old times sake." Severa, no longer able to contain herself, finally accepts her mother and makes her promise not to leave her this time. Cordelia is at a loss since she has yet to say such a quote, but she interprets that her "special" person that she fought to protect was Severa, not Chrom. As Cordelia looks closely at her ring, she discovers that Severa is her future child, causing Severa to confront Cordelia on her final statement saying that she doesn't care because she left her for Chrom. Severa tries to play off her words, saying that she only fought to reclaim what was hers.

Cordelia approaches her and commends her on her skill during the battle. After defeating Nelson, Severa retrieves her ring. When Severa reaches him, she chastises him for fighting for blood money and convinces him to return to his family so his future child will not suffer a tragic upbringing like she did. Severa eventually meets up with her mother and Chrom's army and asks them to help her get to Holland so she can talk to him. Another person, Holland, was also forced to fight as well. In her Paralogue, Severa is forced by Nelson to fight against Chrom's army in order to retrieve her precious ring which was stolen when she was sleeping. Severa joined Lucina and the rest of the children to return to the past to prevent the ruinous future. She was given her mother's ring as her only memento left of her. However Severa would later regret this final argument as Cordelia tragically died in the battle following that conversation. Severa still believed that her mother meant Chrom. Cordelia reassured her by telling her that she fights to protect someone special to her. One day she got into an argument with her mother, questioning if she loved Chrom more than her.

Despite her best efforts to show any sign of prodigious skill, her attempts were considered inferior to Cordelia's natural abilities. In her childhood, she grew up in the shadow of her mother's legacy. Severa is the daughter of Cordelia and can potentially be the older sister of Morgan if Cordelia married Robin.Otherwise she is an only child.
