Foundation's Triumph  Foundation's Triumph (1999) is a science fiction novel by American writer David Brin, set in Isaac Asimov's "Foundation" universe. It is the third book of the Second Foundation trilogy, which was written after Asimov's death by three authors, authorized by the Asimov estate. Brin synthesizes dozens of Foundation-Empire-Robots novels and short stories by Isaac Asimov, Roger MacBride Allen, and authorized others into a consistent framework. " Foundation's Triumph" includes an appendix chronology compiled by Attila Torkos. "Foundation’s Triumph" starts with Hari Seldon who reviews his life and has to accept the fact that his “purpose” is completed. One day he meets a bureaucrat, Horis Antic, who explains his theory about the correlation of certain soils on planets and psychohistory. Seldon agrees to take a trip to some of the planets which fit Antic’s theory. Hari and Horis travel to Demarchia, where they rent a yacht. Parallel to Seldon’s story, Dors Venabili starts out on the planet Panucopia to meet Lodovik Trema, a robot whose Three Laws of Robotics have been erased. Lodovic gives her the head of R. Giskard Reventlov, an important robot who founded the Zeroth Law with R. Daneel Olivaw. She finds out that Giskard and Daneel never consulted a human while founding the Zeroth Law. Later Trema meets a faction of cyborgs and joins them. After Dors has become a rebel, she fights for the cyborgs as well. The third plot of the novel is on Eos. Daneel talks to his possible successor Zun Lurrin. All chapters with Olivaw as the main character are written in a different typeface. In Seldon's story, during the flight to the first planet the yacht is taken over by rebels, who are from the renaissance or chaos planet Ktlina. They show Seldon ancient spaceships with many data capsules from the human past. Robots take over the yacht and destroy the data capsules and the ancient ships with the permission of Seldon. During the flight back to Trantor, a rebel, Gornon Vlimt, turns out to be another robot from a faction of Calvinians, who want to send Hari into the future. At last all factions meet on Earth.
