Worde is a territory in Lycia, member of the Lycian League, featured on the in-game maps of Fire Emblem: The Binding Blade and Fire Emblem: The Blazing Blade. Like all other noble houses in Lycia, Worde is ruled by a Marquess. However, nothing else is known about it canonically since no game events involve Worde or take place there, and it is not even directly mentioned in either game.
However, Worde does appear in the Fire Emblem: Hasha no Tsurugi manga, where it is ruled by Marquess Worde, Lord Ranward. As per the trend of some marquesses being related in some way through Roland, as Lord's Hector and Orun were, he is uncle to Tania's Princess Tiena. Danan is also a resident of Worde, being a soldier stationed at Castle Worde.
