Running with the Demon
Referred To In:
The World of Shannara
As one of the Freemark Women, Evelyn had the use of magic.
When she saw Wraith she worked out he had been left by the Unnamed Demon so she infused all of her magic into him, changing him so that when the demon returned and Nest was in enough danger to use her magic Wraith would no longer follow the demon but would instead protect Nest. This left her without any magic and unable to defend herself when the demon actually came for her.
