The Pillars of Creation (2001)

Jenssen Rahl, Richard Rahl's half sister, spent the first twenty years of her life running from their father, Darken Rahl. Born without any aspect of the gift of magic, Jennsen fears that Darken Rahl will kill her. Upon learning that Darken Rahl is dead, and upon the death of her mother, she sets out to take vengeance upon Richard, having been led to believe that he ordered the death of her mother and blaming him for the brutish actions of the Imperial Order.

Meanwhile, another sibling of Richard's, Oba Rahl, has broken free of his upbringing - a mother who he felt never loved him, and forced him into menial and pointless labor. Taking his vengeance out on his mother, he also sets out on a quest to find Lord Darken Rahl. He finds that the kingdom of D'Hara is under rule by a new lord, Richard Rahl. Oba, who is pristinely ungifted and immune to magic, eventually encounters Richard and his wife Kahlan. Rather than kill Richard immediately, Oba is ordered by the Keeper to kidnap Kahlan and take the Sword of Truth.

Using his link to the sword, Richard pursues Oba to the Pillars of Creation, where Richard encounters Jennsen Rahl, who has also been drawn to the same spot by the Keeper. Jennsen, who was convinced by Emperor Jagang that Kahlan, the Mother Confessor was evil, had plans to kill her. The Keeper's supreme plan, however, was for Richard to kill Jennsen at the Pillars of Creation and open a gate between the Keeper's realm and the world of the living. Before any tragedy strikes, however, Richard and Jennsen recognize the goodness in one another and the Keeper's plan is foiled. Jennsen learns that men who were sent to kill her mother were actually soldiers of the Imperial Order, and after coming to believe that Richard is truly a loving and caring brother, she joins him and Kahlan in their quest against Jagang.
