Hardin's efforts are still resisted by the Board of Trustees and its chairman, Dr. Lewis Pirenne, who erroneously believe they are protected by imperial decree. To remove this obstacle, Hardin and his chief advisor, Yohan Lee, plan a "coup d'état" designed to remove the Board of Trustees from its politically powerful position on the same day that, in the city's Time Vault, a holographic recording of Hari Seldon is programmed to play. The recording will contain psychohistoric proof of Hardin's success or failure; Hardin realizes that his coup is a great gamble due to the possible case that his beliefs are incompatible with Seldon's original goals.
