the Doctor, Roz and Chris discover that an ancient Gallifreyan weapon called an N-Form has been activated, in part by the distorted psychic bond between twins separated at birth. In the 2980s, while human nobles (including Roz's sister Leabie Forrester) fight for control of the Earth Empire, the Brotherhood (which has become a powerful player in galactic politics) hopes to use another Gallifreyan artefact, the Nexus, to induce psychic powers in all human beings. While the Doctor and Chris focus on the threat posed by the Brotherhood, Roz joins her sister in her bid to reform the corrupt Empire. Although the Doctor is able to defeat the Brotherhood utterly, he is unable to save Roz from dying in battle. Leabie becomes Empress, and at Roz's funeral the Doctor suffers a heart attack. While recovering from Roz's death in 1958 London, the Doctor and Chris encounter Moriah, an alien king who has been creating artificial life-forms in an effort to bring back his dead wife, and the Doctor's former companion Peri, who has been trapped in a loveless marriage to King Yrcanos since she and the Doctor parted. In 2003, when Benny and Jason join two archaeological teams searching for Noah's Ark, a ruthless Iranian soldier accidentally causes a deadly biological agent to be released in the Earth's atmosphere, killing hundreds of millions, including Liz Shaw. Benny and Jason agree to divorce. In 16th-century Japan, the Doctor meets Victorian time-traveller Penelope Gate (whom later BBC novels suggest may be his mother) and comes to terms with his recent losses and impending regeneration (of which he is aware). Chris also begins to heal and discover his own form of heroism. Finally, the Doctor returns to his family home on Gallifrey, where long-buried secrets are revealed. Chris decides to remain on Gallifrey and Romana, now Lady President, sends the Doctor to Skaro to retrieve the Master's remains. This leads into the events of the television movie. The Eighth Doctor meets Benny at the house on Allen Road in 1997, and the two of them (alongside the Brigadier) defeat an Ice Warrior invasion. At the story's end, the Doctor takes Benny to her new job in the 26th century, a position at St. Oscar's University on the planet Dellah.
