Margaret Jean Way is of a race of people who have been long hidden. Her people are called; The Leto, meaning hidden or forgotten. When the company accidentally finds their home.... they find that these people have amazing powers. Their Princess is Margaret and she is blind, but her power gives her the ability to 'see' her surroundings without actually seeing it. She can use her sense of smell, touch, taste, and hearing to 'see' her surroundings and others. (Kind of like DareDevil). Gandalf asks for her to join them seeing as they had just left Beorns home and were almost to Mirkwood. (I do not own the Hobbit or its characters. I only own the Leto, it's people and Margaret.)
