The 331-year-old Chairman of the Legislature of Aurora, Horder is normally referred to exclusively by his title. Aurora prides itself on continuity in this office between incumbents, who serve up to two thirty-year terms. By the end of their rule, they tend, like Horder, to become ornery. He is a surprising short man with a reputation for being efficient and hard-working and he gets results. The Chairman is determined to hear both sides of the argument between Dr. Han Fastolfe and Dr. Kenden Amadiro about the future of human colonization of the Galaxy. He dismisses the importance of the immediate dispute over who has killed R. Jander Panell. The Chairman is less interested in truth than peaceful expediency, and his recommendations to the Legislature are likely to be adopted. Failing to get Amadiro to compromise, Horder sides with Fastolfe. R. Giskard Reventlov reveals that he has several times lightly nudged Horder's mind to obtain desired results.
