Return to L’Academie during Act II to find an old woman to the east of the entrance looking for some assistance. She wants you to track down a woman that never received her Diploma a long time ago. Once you reach Sniflheim and bring peace to the kingdom once more, head upstairs in the Weapon shop to find a young girl. Upon speaking to her you’ll discover that the woman was her grandmother that has now passed. Return to the woman back in L’Academie to report your findings and complete the quest.
