Tolna can inform the party about the most rare books owned by the Sorcerous Sundries. However she refuses to sell them or even show them to the party. However, if pressed she reveals that the books are kept in the vault and how to gain access.
Tolna is also a merchant who sells scrolls and books.
If a party member chooses the dialogue option "IS THAT TRUE BOOKS? ARE YOU SENSITIVE?", the books on either side of her erupt in fireballs. She then (understandably) becomes extremely upset and refuses to reveal the location of these rare books or trade with the party until they pay her 400 gold to cover the damages.
Tolna's attitude towards the party often changes depending on the outcome of Stop the Presses quest.
