Nanna is a playable character from Fire Emblem: Genealogy of the Holy War and Fire Emblem: Thracia 776. She is the daughter of Lachesis, the younger sister of Diarmuid, and a cousin of Ares. As a member of the noble family of Agustria's House Nordion, she possesses minor Hezul blood. By the end of Thracia happenings, she is married to Leif, though both can be paired with other characters during the events of Genealogy of Holy War. Nanna's substitute character is Jeanne in Genealogy of the Holy War. Nanna's characterisation is inconsistent between Genealogy of the Holy War and Thracia 776. In Genealogy of the Holy War, Nanna is portrayed as a headstrong and determined person, as shown through her assertiveness in urging Leif and Finn to abandon Leonster and seek cover in a nearby church. If Finn is her father, he even likens her to her mother Lachesis, who is similarly stubborn and strong-willed. Yet in Thracia 776, the strong character that Nanna possesses in the previous game is absent. She is markedly quieter and more reserved, and this can immediately be seen in Chapter 1, where her capture by Raydrik sees her doing nothing to fight back, instead silently accepting her circumstances. Chapter 5 only reinforces this change in Nanna's characterisation, where she, seized by fear in the arena, heavily relies on Eyvel's protection to stay alive despite being armed herself. This is possibly due to the fact that Thracia 776 occurs a year before Genealogy of the Holy War, and after Nanna's hardships in the game, she grew into a headstrong woman like her mother.
