The Heartflask sidequest is a extremely time consuming side-quest found in Baten Kaitos Origins. To start this sidequest is necessary to have a Baten Kaitos: Eternal Wings and the Lost Ocean save on the memory card and then speak to Georg in the Nihal Desert. This side-quest gives no rewards other than filling 5 spots on the gathering list. It's not necessary to be taken to Georg after every change for inspection, but taking it to him will grant extra info on it.
