Gengo arrived to the Land of Silence and seized the nation. He developed an auditory genjutsu called "Demonic Illusion: Cajolery of Glamour" to manipulate others into working for him by forcing them to reassess their ideals to match his, allowing him to come closer to his ambition of taking power away from the daimyos. He easily became the ruler of the Land of Silence, and the leader of the Enlightened Ones, a cult that much of the population was a part of, thanks to his auditory genjutsu.
