The Mord-Sith, also known as evil birds, are an elite group of highly stylish women dressed in red leather. Their training makes it hard for a confessor to "read" them. A confessor's touch is deadly to a Mord-Sith. Once confessed, they only have a limited amount of time before dying. Mord-Sith also have the power to resurrect dead humans with their mouth (the breath of life). They torture their prisoners, until they are completely devoted.
A Mord-Sith is selected at a young age to begin their training. They are struck by an agiel as part of their training. Eventually, the girl will "break" and that is when her training is complete. Once completed, they are told to kill their loved ones to prove to their Mistress that they are no longer innocent. After they prove their loyalty, they are to serve Darken Rahl and his successors.
