Memory Restoration Spell

Zelda and I were talkig and she seems to be having some memory gaps. She doesn't remeber much about her life prior to waking up here in this new place. I said that I remeber everything prior to waking up here. I told her that I have a spell in my copy of the Grand Grimoire that helps restore lost memories. I offered to cast that spell upon her and she accepted as she didn't have that spell. I told her that it may take a few days for the spell to take effect before we said our goodbyes.
