Imperial Child's Mind is the name given to a sidequest in Baten Kaitos: Eternal Wings and the Lost Ocean. The quest takes place on the third floor in one of the dwellings in Azha. A boy will be blocking access to the upper levels and will only move once he's heard a Girl's Thoughts (obtained in a house in Mintaka). He'll give you Red Oak for sharing, and the now accessible upper portion of the house contains Magnus including a Sunflower Coin, Jumbo Pastry, and Pork Ribs. This quest is only completable before the village's resident flee for Nihal Desert. At that point the upper floors and the Magnus they contain will still become accessible, but Red Oak will not be rewarded.
