A subtle, soft spoken man, Edorion is noted as being clean shaven, dark haired and lean, with a serious look except when smiling. When he first meets Rand al'Thor, however, he is described as being plump.
He is playing cards with Mat when the cards become life-sized and attack Mat.
While out looking to find help for Cairhien when the Shaido attack, he finds Rand al'Thor with the rest of the Aiel. He makes a wager with Rand that he will not make it to Cairhien to stop the Shaido in seven days. Later he is part of the escort that greets Rand al'Thor when he enters Cairhien after the battle with the Shaido, and he is no longer plump.
He later joins the Band of the Red Hand and travels to Murandy where King Roedran employs the Band to stay on the border. After the employment is completed, he sets off with a number of the Band's banners and finds Mat in Altara.
