A delivery lady
Older than she appears
She has to wear a blindfold for protection during her deliveries, because the immense, magically imbued scrolls she carries could seriously maim her if she read so much as a single character (the power of great written magic overwhelms those with little or no magic ability).
She crosses danger ridden wastelands so as to avoid other travelers (they could get killed if the curiosity got the best of them!). It can be pretty difficult to do even without a blindfold. Her unusual skill makes her the first (and only?) choice for magical scholars seeking to transport powerful spells.
Serves many temples and mage circles.
