Dathomir lies in the outer rim in the dathomir system. The planet’s atmosphere and temperature allows for humans to survive on the planets surface. Whilst a large majority of the planets surface is habitable only a small portion of the planet has been explored and the entire population are found in a small area along the coast of one of the 3 main continents.
The planet is home to many native species and the mighty rancor is considered to be the apex predator, its size was larger than other species of rancor’s due to the planets relatively low gravity.
Dathomir has a long history reaching back beyond a 100,000 BBY when the native reptilian creatures called the Kwa ruled dathomir. The native Kwa built the Infinity Gate which enabled interstellar travel and had the ability to be used as a superweapon.
Dispite the intelligence and strength of the Kwa their species begain to denigrate and would eventually loose the ability to speak or use the tools they had once built.
Many milleniua later around 30,000 BBY the planet and its people would be subdued by the Rakata. The rakata would rule the planet and the galaxy for thousands of years before finally departing Dathomir.
Eventually the Jedi order would banish a rouge Jedi knight named Allya to Dathomir and in doing so set into motion the foundation of of the Witches of Dathomir.
As the years passed Allya would teach the natives the ways of the force and she would be remembered as the one who transformed the ways of dathomir society that would one day make way for the reign of the Nightsisters and the inbreeding of Zabraks with the Humans to eventually create the Nightbrothers.
The importance of these sequence of events would be realized when Darth Sidious visited dathomir in 54BBY and was approached by a nightsister who would give the one who would later be known as Darth Maul over to darth sisdious for training.
The nightsisters would remain the dominant force on Dathomir until the Battle of Dathomir which took place dudirng the clone wars when General Grevious lead a vicious assault on the nightsisters and lead to their near extermination at the hands of grevious.
For a time after the fall of the nightsisters the planet’s importance would fade into obscurity until the Yuuzhan Vong War when Dathomir fell to the Yuuzhan Vong around 27ABY but would later fall back under the New republic.
