Ethlin is a Troubadour in Fire Emblem: Seisen no Keifu. She is Siglud's sister and Duke Cuan's wife. She succeeded upon the death of her mother. Her sister-in-law Diadora gives her the Light Sword, which she can pass onto her son Leaf. According to unofficial manga, she was born in Gran 739. She stands 164 centimeters. She weighs 47.1 kilograms, and her blood type is A. She is killed alongside Cuan while protecting her daughter Altenna during Trabant's ambush in Chapter 5.
Ethlin, unlike her brother Siglud, is not a good fighter. Her main purpose is healing, but her terrible magic growth means she isn't more then decent at that. Remember to get her the Light Sword by having Diadora talk to her in Chapter 2, and sell her Heal staff before the end of Chapter 3, since Leaf can't inherit it
