Located in the Quelli sector, Dathomir is a low-gravity world with three continents, a wide ocean, and four small moons. The planet is covered with a wide variety of terrain including mountains, deserts, purple savannahs, and forests with eighty- meter trees and vines bearing hwotha berries.

Indigenous life on Dathomir includes flying reptiles, piglike rodents, long Whuffa worms, burra fish, and the feared rancors. Semi-intelligent, two-legged reptiles live in the desert and call themselves the Blue Desert People. 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 the two-kilometer Jedi spaceborne academy Chu'unthor crashed in a Dathomir tar pit, and the Jedi force sent to recover it was repulsed by the witches-- those female inhabitants who had learned to use the Force. Different clans of the 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. 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.
