Who is Adie the Bone Woman from Wizard's First Rule and what is their importance?

When Chase and Zedd are injured, the kindly innkeeper Bill directs Richard and Kahlan to the cottage of a healer, Adie the bone woman. She is a frail-looking elderly woman with only one foot, who has a large collection of bones in her tiny cottage, many of them from creatures of the underworld. Adie casts a spell on Zedd and Chase to help them heal, and takes care of them while Richard and Kahlan continue on their quest. When Zedd recovers, he restores Adie's foot with magic and the two develop a romance.
