Nyna

Nyna (called Nina in the Japanese version) is the Princess of Akaneia. She was the only royal family of Akaneia left when the Dolua Empire invaded. Fortunately, she was protected by the Grunian Black Knight Camus, who eventually hands her over to the Orleans Kingdom, which is much safer than her kingdom at that time. Assisted with Hardin, she joins up with Marth and eventually accompanies him in his quest, handing over the Akaneian royal treasure Fire Emblem for Marth. Unfortunately, Marth's quest led him to fight against Camus, in which he was defeated. Nyna was struck with grief when she thought Camus died, but she held up and accompanies Marth to the end of his quest.

After the battle, Nyna was forced to make a choice on who is to be the new emperor of Akaneia. One of the choices is Marth, but as she is also a good friend of Shiida and did not want to break her heart, she picked Hardin instead. Due to this, she could only show platonic love to Hardin, which in turn shatters his heart and later turned over the dark side, she blamed herself for Hardin's fall to darkness. Before she was taken by Gharnef to be sacrificed for Medeus' revival, she managed to entrust the Fire Emblem to her apprentice Linde and orders her to give it to Marth. In the end, Camus, turning out not dead yet and taking the identity of the knight Sirius, wakes her up from Medeus' mind control. Afterwards, she abandoned the kingdom and vanished, presumably following Sirius.
