Ki-Adi-Mundi was a Cerean alien who sat on the Jedi Council. A humanoid being, Ki's most distinguishing physical feature was an enlarged conical cranium that contained a binary brain. When Jedi Master Qui-Gon Jinn reported a Sith attack during the events surrounding the Battle of Naboo, Ki-Adi-Mundi expressed shock at the notion. "Impossible," he remarked, "the Sith have been extinct for a millennium." He also failed to see how far Count Dooku had fallen from the Jedi ideals just prior to the Clone Wars, believing that Dooku was incapable of violence or murder. The Clone Wars were a harsh education for the serene Jedi Master, as he was pressed into service as a battlefield general. Ki-Adi-Mundi served on hostile, exotic worlds such as Geonosis and Mygeeto.
