Caeda is the princess of Talys, an island nation off the coast of Archanea in Fire Emblem: Ankoku Ryu to Hikari no Ken and its remakes. At the start of the game, it is revealed that for several years, her family has provided refuge for Marth and his remaining allies from Altea after they are forced to abandon their home. She makes her first appearance at the start of Chapter 1, in which she arrives to inform Marth of a pirate attack and requests his aid in driving them off. After the mission is a success, Caeda chooses to travel with Marth when he decides that it is finally time to return to the mainland and fight to reclaim Altea.
Caeda's default class is Pegasus Knight.
Caeda appears as one of the numerous collectable stickers in Super Smash Bros. Brawl. Released in the west prior to any Fire Emblem game featuring her, her name in the game was romanized as "Shiida" or "Sheeda". The romanization was changed to "Caeda" with the western release of Fire Emblem: Shadow Dragon.
