Null ( species ) The Nulls were a species of tall Near - Human s who inhabited the eponymous planet of Null . A fierce and individualistic people , they had a culture of hunters and stonemasons , and they based their planetary economy on hunting tourism . In 22 BBY , when the Clone Wars broke out between the Galactic Republic and the Confederacy of Independent Systems , their planet became part of the Confederacy , although much of the populace had a great respect for the Jedi , the devoted protectors of the Republic . Following the Battle of Endor in 4 ABY , a Null Imperial Intelligence agent was employed by the Church of the Dark Side as an imitator of the Emperor ' s Mage Jedgar , an imposingly tall Human who matched Nulls in height . Biology and appearance . The Nulls closely resembled baseline Humans , with four limbs , a bipedal stance and a relatively hairless body . However , the Nulls could be easily identified by their towering stature . Some individuals were known to be a meter taller than the Human Jedi Anakin Skywalker and Obi - Wan Kenobi , whose respective adult heights were 1 . 88 and 1 . 82 meters . Humans with abnormally high linear growth could easily pass as Nulls , and vice - versa . Like Humans , the Nulls had hair covering their scalp . Male members of the species also grew long and heavy beards on their chins , which they usually braided for aesthetical reasons . At least one male individual , a professional impersonator , was known to have light skin , a prominent chin , hooded eyes and a large , hooked nose . That one Null also had his hands roughly the size of a grown Human ' s head . Society and culture . On their eponymous homeworld , the Nulls lived in small individualistic communities with a strong sense of privacy . The planet had no large cities , and although there existed a planetary government with its system of laws , criminality was normally handled among villagers through fierce retaliation . The Null villages had narrow streets , cluttered with low buildings made of stone and wood . At the time of the Clone Wars , the villagers would seldom use speeders and usually relied on the bellock s for transportation . Individuals of both sexes dressed in thigh - length boots and animal skins . Hunting was an important activity on Null , since the planet ' s mountains were full of wild beasts prized for their skins — such as the wily laroon . Despite their fierce nature and their keen sense of privacy , the Nulls normally displayed a friendly demeanour towards strangers , especially since their planet ' s economy relied on hunting tourism . Although their habitations could be considered archaic by galactic standards , the Nulls were in fact master stoneworkers . They built walls from jagged stones , fitting them together in complex patterns , but without mortar or joinery to bind them . More than mere architecture , this specific knowledge was considered an art form . History . The Near - Human s known as the Nulls hailed from the forested planet of the same name , located within the Trans - Vulta sector , in the Mid Rim region of the galaxy . The Nulls ' world was first discovered by outside observers between 5000 and 3000 BBY . On the fifth month of the year 22 BBY , a galaxy - wide conflict know as the Clone Wars broke out between the Galactic Republic and the Confederacy of Independent Systems . Since Count Dooku — former Jedi Master and head of the Confederacy — almost wholly owned the planet and had ties with its leaders , Null quickly sided with the Confederacy . However , the common people went on with welcoming tourists from other worlds . Three years later , the Clone Wars were brought to an end , and the Republic was replaced by the first Galactic Empire , an authoritarian government led by former Supreme Chancellor Palpatine . Nulls in the galaxy . In 4 ABY , the Empire was defeated at the Battle of Endor . The former Director of the Imperial Intelligence Cronal helped acting - Emperor Sate Pestage set up a mock religion known as the " Church of the Dark Side " on Coruscant , establishing a body of false Prophets of the Dark Side . Cronal recruited a Null Imperial agent named Heingort Giddis , instructing him to impersonate Jedgar , the real High Prophet of the dark side , who was believed dead . The impostor served along with Rajah Ubooki , a Bimm impersonator posing as the Supreme Prophet Kadann , and they sought to seize the secrets of an ancient Jedi Library on Yavin 4 . However , the so - called Prophets were defeated by the heroes of the New Republic , and were eventually murdered by the Imperial Grand Admiral Afsheen Makati . Behind the scenes . The Nulls first appeared in " Legacy of the Jedi " , a young readers novel written by Jude Watson and published by Scholastic on August 1 , 2003 . In early June 2006 , " Star Wars " author Abel G . Peña wrote " " , an online supplement to the eighty - eighth issue of the " Star Wars Insider " magazine . In this article , Peña identified a character from the 1990s " Jedi Prince " series as a Null impostor , thus retcon ning the species ' s first appearance to Paul and Hollace Davids ' novel " The Lost City of the Jedi " , published on June 1 , 1992 .
