Amaresu is one of the Heroes of the Horn.
She fights with the Sword of the Sun, which glows in her hands.
She is mentioned as being present when Matrim Cauthon blows the Horn of Valere at Falme. Later, Mat remembers her when he recognizes Birgitte Silverbow. When Egwene al'Vere is captured by the White Tower, Nicola Treehill and Areina Nermasiv compare Egwene to Amaresu and Birgitte.
