Denna

"You may call me Mistress Denna"- Denna

Denna was a Mord-Sith a female warrior woman tortured and trained by Darken Rahl to protect him from creatures with magical powers. She was an antagonist in the show Legend of the Seeker.

Training the Seeker
Denna received orders from Darken Rahl to capture and train the Seeker Richard Cypher. She along with her fellow Mord-Sith Constance and several D'Haran soldiers captured Richard. Richard later woke up chained by his wrists up to the ceiling only to see Denna who started torturing him with her Agiel. Denna's plans was to torture him into obeying her, but he was able to resist her. Later Richard's companion and love Kahlan Amnell tried to rescue him, but she had her captured as well. Later they managed to fight and kill Denna and Richard killed her with his sword. Later her fellow Mord-Sith Constance revived her with the Breath of Life.

Pristinely Ungifted
As punishment Darken Rahl had her tortured by himself, after that he commanded her to get the last Box of Orden with the help of the Pristinely Ungifted one Jennsen (who was Richard's sister) who has immunity to magic. She by threatening to kill her mother, had Jennsen take the Box of Orden by going through a force-field. Later Richard and his companions found her torturing Jennsen's mother. Richard and his friends managed to rescue Jennsen except her mother. Later Richard made a deal with Denna- have Jennsen take the rest of the Boxes of Orden and the last Box to be given to Denna in exchange for their mother's safety. Before that happens Denna suddenly kills their mother with her Agiel and promises to revive their mother with the Breath of Life once she has the whole Boxes of Orden. When Richard gains all three Boxes he used their power to take control of Denna's mind and commanded her to revive their mother. But she couldn't revive her as the usage of the Breath of Life had a time limit on a dead person. Enraged Richard commanded Kahlan to beat her to death (The power of Orden corrupted his mind). Later after Jennsen managed to release Richard from the power of Orden, Denna begged him to kill her, fearing Darken Rahl's wrath. Richard instead left her alone to run from Darken Rahl.
