The story takes place in the world

The story takes place in the world author Terry Goodkind created in his The Sword of Truth fantasy novel series. The three main provinces are Westland, the Midlands and D'Hara. Westland is separated from the Midlands by a magical boundary, which was created to prevent any magic from entering Westland. On the other side of the Midlands is D'Hara, which is ruled by Darken Rahl. Seekers are accompanied by a Wizard of The First Order and Confessors, an ancient order of women, who oversee the welfare of the people of the Midlands and the Seeker.

The first season is loosely based on the first book of The Sword of Truth series Wizard's First Rule. Some of the stories feature events and characters not encountered in the books, while others loosely adapt events from the book. The story begins after the invasion of Darken Rahl's army into the Midlands. Kahlan Amnell, a Confessor, ventures into Westland in search of a wizard and the Seeker, who has been prophesied to defeat Rahl. Kahlan finds the wizard, Zeddicus Zu'l Zorander, and the Seeker, a young man named Richard Cypher, who is forced to accept a destiny he never knew about. Together, they set off on a quest to seek out and defeat Darken Rahl. The second season is loosely based on Stone of Tears, the second book in Goodkind's series. It tells the story of how Richard, Kahlan, and Zeddicus discover that their quest during the first season caused them to unintentionally help the Keeper of the Underworld create tears in the veil which separates the land of the dead from the world of the living. Their new quest is to find the Stone of Tears, seal the rifts between the worlds, and defeat the Keeper. They are joined in this quest by Cara, a Mord-Sith and their former enemy
