Dathomir, nicknamed the "rancor planet," was a remote, neutral planet in the Quelli sector and the home of the Nightsisters, Nightbrothers, Blue Coral Divers Clan, Singing Mountain, and the Howling Crag. The planet, bathed in blood-red light by its central star, had numerous continents that were overrun with vegetation, forests, and swamplands. The dark side of the Force had an immensely strong presence on Dathomir, which allowed for the nurturing of many malevolent Force wielders native to the planet. The Nightsisters, also known as the Dathomir witches, made their home in the swamps, and wielded magicks fueled by Dathomir's own power. Dathomir was also home to the Nightbrothers, Zabraks who were ruled by the Nightsisters. It was also the homeworld of the semi-sentient rancor species
