Hannah

"Heh heh heh. I'm here, too. Speak to me for auguries before you engage the enemy. My service are not free, but they may save you from paying a greater price!"

Hannah is a fortune-teller who joins Eliwood and Hector's army at the start of Chapter 14: 'False Friends' to offer augury of the battles ahead. She leaves the group after they proceed to visit the Dread Isle and her task is then taken over by the newly re-recruited Nils. Hannah never appears again, not even in the epilogue, probably as she never was intended to be an important character.

An elderly witch who looks (and laughs) exactly like Hannah appears in one of the villages of Chapter 13 to give the unit visiting it the first mine in the game, which she claims is an invention of hers.

Hannah's Augury
Hannah's augury costs a bit of money, depending on the chapter, but it can be quite helpful if the player is unsure how to prepare. Her prophecies usually includes the types of weapons that will be useful in the battle, and the presence of new allies as well as hints on how to approach them.
