The Fish Speakers are an army created by the God-emperor, Leto II Atreides. On ascending the throne, Leto realized that an all-women army was the key to achieving the golden path. Leto II believed that an all-men army turned against the population in the lack of an enemy but, an all-women army nurtured and cared for the people like mothers. Throughout his 3,500-year reign, the Fish Speakers were Leto II Atreides's primary army.
