The Wishsong of Shannara
The Shannara Chronicles
Referred To In:
The World of Shannara
Mord Wraiths were also known as Black Walkers.
After Shea Ohmsford defeated the Warlock Lord and his followers, the Ildatch was recovered by a sect of human followers of the Warlock Lord. These would-be sorcerers were not subject to the Sword of Shannara and so were not destroyed along with him. Sixty years before the events of The Wishsong of Shannara they took the Ildatch to their Eastland lair and began to delve into the magic. They were subverted by the magic, becoming Mord Wraiths.
