Baudin tells you that his sister, Audia, has become cursed by some unknown force and craves the bloody raw meat of coeurl. Baudin is very concerned with his sister's well being and wishes he could do something to help. He mentions that Audia's fiance, Albrecht, prays at the Cathedral every day for her well-being.
Head to the Cathedral in Upper Jeuno and speak with the minster Mailloquetat for a cutscene with Albrecht, who tells you that none of his prayers have been answered and that his fiancee is still cursed.
Return to Baudin who will ask if you have any news of his sister's condition. After you say "no, nothing" Albrecht appears and inquires if there were any changes.
