Ethlyn

Ethrin is a Troubadour in Fire Emblem:Seisen no Keifu. She is Prince Sigurd's sister and Duke Cuan's wife. She uses both swords and staves similarly to the promoted Mist from Fire Emblem: Path of Radiance and the starting Mist from Fire Emblem: Radiant Dawn. It is also interesting to note that both Mist and Ethrin are Staff-users and are the sisters of blue-haired main characters.
