Ethnia

Ethnia is the youngest daughter of Leptor and she is the mother of Amid and Linda. After hearing that her dear sister Tailto was fighting on the rebel army's side, she left in search of her.

According to the Fire Emblem: Thracia 776 Illustrated Works, Ethnia was the Queen of Alster and protected Leaf and his friends when they visited Alster between the Year 762 - 765. It is possible that Ethnia may be the mother of Miranda, the princess of Alster, but it is unclear.

When crossing the Great River of Thracia, Leaf mentions Ethnia as being the Earth Goddess. Whether they are the same person is just as unclear.
