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.
Heartflask (1): A vessel Georg gave you for collecting people's hearts. It's still just a prototype, so who knows what will happen. You'll need to have Georg inspect it periodically if you want to keep using it.
Heartflask (2): The vessel is filling with hearts, just like Georg said. It's still just a prototype, so who knows what will happen. You'll need to have Georg inspect it periodically if you want to keep using it. (appears as third of the five on the gathering)
Heartflask (3): The vessel has filled up with even more hearts. It doesn't seem to be after YOUR heart--but one has to wonder what Georg plans to do with this. Don't forget the periodic inspection!
Heartflask (4): The vessel has nearly filled with hearts. It almost feels like you've gained a second heart yourself. Georg still hasn't disclosed his plans, though... Requires periodic inspection, of course. (appears as fifth of the five on the gathering)
Heartflask (5): The vessel has filled completely, and it's bursting with hearts. Within it, you feel something akin to the birth of a new life. Is returning this to Georg really the right thing to do? (appears as second of the five on the gathering list).
