Fire Emblem: Fortune's Weave's "Legacy of a Legendary Sculptor" quest tasks you with deciphering four vague clues in a sort of scavenger hunt around the empire. You're meant to track down four statues of four of Dagda's goddesses, hidden in places relevant to their lives and worship. Mostly. It's a time-consuming task that requires ample free time to complete, but the rewards are quite nice and worth the hassle.
