Lucina

Lucina is the daughter of Chrom who was born within the two-year period after the end of the Ylisse-Plegia War. Due to the death of her aunt Emmeryn, Chrom took on the role of Exalt, making Lucina the Crown Princess of Ylisse. As proof of her heritage, Lucina's Brand of the Exalt appears on her left eye.

In the original future, Lucina recounts that she spent a lot of time with Chrom, developing a particularly strong bond with him. She was taught swordplay from an early age by Chrom himself, of which she showed significant talent and also his penchant for unintentionally destroying training dummies. She was also deemed worthy to wield Falchion by the blade itself.

Chrom was often away, dealing with the Grimleal in particular. With the help of the Shepherds, he eventually faced off against Validar at the Dragon's Table. With his most trusted allies by his side, the cult leader was slain, however Chrom was betrayed by his closest ally and killed. Chrom's death lead to the resurrection of the Fell Dragon Grima who laid waste to the future.

His destruction killed all of the Shepherds, leaving behind only their children, including Lucina. Despite this, Lucina recovered Falchion and used it to help fend off the Risen and fight back against Grima. It is implied that she attempted to evoke the Awakening, but without the necessary means to perform the rite in full, she was only able to partially empower Falchion. With little hope left for humanity, the Divine Dragon Naga gathered the children of the Shepherds. Opening a portal in time, Naga sent them into the past in hopes of averting the ruinous future.
