The woman chuckles and says; "Perhaps tempting bargain but you forgot about the spell which was placed on me; all my memories regarding my city and it's people were mostly erased away permamently. So I cannot sell you anything even if I wanted or you tried torture me. This much paranoid my own people are about discovery they go this much effort to make sure nothing of our city cannot be revealed to outsiders. So sadly only what I can offer is same lore as anyone else minus my own specialities and tricks in trade as jack-of-all-trades spellcaster, that's it."
