Humans came to Dathomir hundreds of years ago when a group of illegal arms manufacturers were exiled to the planet by the Jedi Knights. Several generations later, a rogue Jedi named Allya was also exiled to Dathomir. Allya began to teach the Force to the planet's inhabitants and to her descendants, who also learned to tame the wild rancors. Some time later, nearly four hundred years ago, the two-kilometer Jedi spaceborne academy Chu'unthor crashed in a Dathomir tar pit. (The Jedi master Djinn Altis was known to travel in a ship also called the Chu'unthor, but based on available dating information it is unlikely that it was the same ship.) Yoda and the other Jedi sent to recover the crashed Chu'unthor were repulsed by the witches-- those female inhabitants who had learned to use the Force. Different clans of these witches (such as Singing Mountain, Frenzied River, and Misty Falls) were formed, including a group following the Dark Side calling itself the Nightsisters. Life among the clans followed a pattern of female dominance, where males were largely treated as property and not allowed to act in important decisions. Around one hundred years ago, the Nightsister Charal managed to escape from Dathomir and fell in with a group of alien marauders, who then crashed on the forest moon of Endor. Imperial forces later constructed orbital shipyards and a penal colony on the surface. Following the failure of the Emperor's attempt to destroy the Jedi enclave on Belsavis, several designers of the Eye of Palpatine were reassigned to punitive duty at Dathomir. After the Emperor learned the power of the Nightsister leader Gethzerion, he ordered all the prison's ships destroyed from orbit to prevent her from leaving the planet. The stranded Imperials at the prison were then enslaved by Gethzerion and the other Nightsisters. Four years after the Battle of Endor, Han Solo won the planet Dathomir in a high-stakes sabacc game from Warlord Omogg, who claimed it had been in her family for generations. Han's subsequent adventures on the planet resulted in the destruction of both the Nightsisters and of Warlord Zsinj's forces. Nineteen years after Endor, a new order of Nightsisters based in the Great Canyon emerged on Dathomir. This clan, allied with the Empire and founded by Luke Skywalker's former student Brakiss, treated their males as equals and sent their best Force students to be trained on the Empire's Shadow Academy.
