Tailtiu is a playable character from Fire Emblem: Genealogy of the Holy War. She is a noble of House Friege, one of the dukedoms of Grannvale. She is the first daughter of Reptor, the younger sister of Bloom, and the older sister of Ethnia. If she is paired up, her children will be Arthur and Tine. She is also the aunt of Amid and Linda, who happen to be her children's substitute characters. At the time of her introduction, Tailtiu appears as a rather bright and bubbly girl with no wish to mingle with complicated politics, especially if they involve her father. She developed a crush on Claud prior to her introduction and claims to be his bodyguard. However, after Reptor turns hostile against Sigurd's army, Tailtiu begins to display her true personality, one which is of a concerned and insecure nature, as she fears that her relationship with Reptor will strain her bonds with her allies. Tailtiu suffers greatly after the Battle of Belhalla, where she quickly becomes depressed as a result of the stress she endures from surviving and losing contact with her husband and son. This depression of hers ultimately leads to her eventual death. Even at her lowest point, she is still extremely protective towards Tine, willingly standing up for her and taking on the tortures meant for her daughter whenever she could. Even after her death, Tine still looks towards her mother as a source of inspiration, wondering what Tailitu would have done in her place on the battlefield. Tailtiu makes her first appearance in Chapter 3 when she accompanies Claud to the Tower of Braggi after Sigurd's army seizes Madino Castle. She does not reveal very much about her reasons for doing so, apart from claiming to be Claud's bodyguard, to which the latter makes a failed attempt to deny. After surviving the horrific Battle of Belhalla, Tailtiu and her young children, Arthur and Tine, spend a certain number of years hiding in Silesse. This false sense of security is quickly broken, however, when Bloom shows up there. While Arthur manages to evade capture, Tailtiu and Tine are forcefully separated from him and thereafter imprisoned by House Friege. Tailtiu then withstands years of abuse from her cruel sister-in-law Hilda to protect her daughter, eventually succumbing to depression and death.
