The Roc Feather is a Quest item in Golden Sun: Dark Dawn and is the primary reason why Matthew, Karis, and Tyrell set off on a journey. It is obtained from the Mountain Roc and, because it is an important item, it can never be dropped or sold.
This feather is apparently of tremendous size and good stability, praised qualities that make it mandatory for creating Soarwing machines. After Tyrell breaks a Soarwing, Isaac assigns Matthew's party to collect one of these feathers in order to build another Soarwing, which is important to Isaac and Garet in their investigations concerning Mt. Aleph and its surrounding area. After a long journey across Angara, Matthew's party end up in Morgal, where they meet up with Ryu Kou and Hou Zan at Kolima Junction and obtain the Slap Glove, an item needed for waking the Mountain Roc from its slumber. As the party approaches the giant bird at the summit of Talon Peak, they use the Slap Glove to awaken the Roc and obtain a feather. After these events, the feather remains in the inventory of the group and has no further use in Dark Dawn.
Although there is no hint what actual use it could now have for the party, it can still be assumed that this item will make a return appearance in the next Golden Sun game.
- Prior to obtaining the item, the shopkeepers at Saha Town are looking for some Roc Feathers so they can sell them for a fortune. After the party obtains the item and presents it to the shopkeepers, they reject it, saying that the feather shown to them is not the real thing.
