Sister Garaele has been tasked by her superiors to question Agatha, a banshee, about a particular spellbook the Harpers have been searching for. Garaele was injured when she attempted to approach the banshee. She gives the party a jeweled silver comb to be given to Agatha in exchange for an answer. She then will answer a single question. She wants you to ask her the location of this spellbook, "Bowgentle".
Sister Garaele can only offer 3 potions of healing as payment.
