The devastating event known as the Raining Leaves Clan massacre transpired around 33 ABY. It involved a substantial uprising by the male slaves belonging to the Raining Leaves Clan, a group of Dathomiri Witch traditionalists who followed a matriarchal structure. The slaves turned against their Witch masters.
Under the cover of darkness, the men launched their attack, resulting in the deaths of every Witch within the clan. In a single night, the Raining Leaves Clan was deprived of its most skilled and knowledgeable Witches. The sole survivors were those who happened to be away, either performing tasks or engaged in hunting expeditions. Upon discovering the revolt, the surviving Witches responded with vengeance, employing their mystical powers and slaughtering all males older than ten years of age.
