Nagi

Before Marth and his forces take on Medeus, Gotoh sends them to a tower in another world telling them to seek the aid of the tower's master. After passing the trials within, Marth's soul cries out to Nagi, waking her from her slumber. Although she can only remember her own name and has vague familiarity when Marth mentions Gotoh, she feels that she must join Marth in his battle against Medeus and presents him with another Falchion. If she faces Medeus in battle, he will note that he was not the only dragon revived and that she had recovered even less power than he had. In the end, Nagi disappears after the final battle, even before Marth could thank her for her help. To reach the chapter that visits the tower, Tiki must be slain and the Falchion must be lost. When Nagi joins, she gives Marth a weaker version of the Falchion. Nagi reappears at The Dragon's Table in Fire Emblem: New Mystery of the Emblem, although Marth does not recognize her, only feeling slight familiarity.
