Hari Seldon Hari Seldon is the founder of the two Foundations. He is a psycho-historian who, through the calculations of psycho-history, predicts the downfall of 'The Empire' and a potential 30,000-year interregnum. He sets up the First and Second Foundations to reduce this huge gap from 30,000 years down to 1000 years. Following a trial, Hari Seldon and his 100,000 followers are exiled to the planet Terminus where the First Foundation is set up. Unknown to many, a Second Foundation is set up at a separate location. Clues to its existence come from a statement by Hari Seldon of it being at 'Star's End'. Many searches are made for this and several of the characters have their own theories about where this is. Homir Munn Homir Munn is a librarian and owns one of the biggest collections of information about the Mule. Munn is one of five conspirators central to the plot of Second Foundation, who plan to find the location of the Second Foundation. Homir Munn "is a stutterer described as "lanky," "ill-at-ease," and "introverted." Marcia J. Myers found that this "stereotype behavior gives this librarian's image an overall rather negative rating". The Mule The Mule is a central character in Foundation and Empire (1952) and Second Foundation (1953). The Mule's name is a reference to the sterility of mules, since he is also genetically sterile. Without a child, the Mule's empire ends soon after his death. According to his autobiography In Memory Yet Green (1979), Asimov modeled the Mule's physical appearance on Leonard Meisel, a friend at the World War II-era Navy Yard in Philadelphia. In keeping with the Foundation series being based on the Roman Empire, the Mule has historical parallels with Attila the Hun, Tamerlane, and Charlemagne; he has also been compared to the Roman Emperor Augustus, Napoleon, Adolf Hitler, Stalin, and several other tyrants and demagogues of recent history.
