The Ones The Ones were a family of exceptionally powerful Force wielders who lived on the planet Mortis during the Clone Wars . Led by the Father , the Son and Daughter were embodiments of the dark and light sides of the Force , respectively . The Son and the Daughter were worshiped as the Twin Deities or simply as the spirits in the Nightsisters ' religion . History . The beginning . Originally , more than a million years prior to the Clone Wars , the Celestial s , mysterious beings who were thought to be capable of restructuring space on a massive scale , lived in the galaxy . According to Thuruht , the oldest of the Killik hives , " the Ones are what the Celestials become . " Thuruht distinctly " remembers " the Ones coalescing out of a geyser on an unnamed tropical planet ; there were three of them — the Father , the Son and the Daughter . They gained these memories from the Son and Daughter themselves , who joined the hive mind briefly to help coordinate the construction of Centerpoint Station . It should be noted that the collective memory of a Killik hive does not make distinctions between fact and fiction like the human mind — any individual memory joined to that of the collective , be it mythology , incontestable fact , or the plot of a holodrama , is history to the Killiks . The Ones initially lived in peace and harmony in the home they made for themselves near the site of the geyser . The Father warned his children to never drink from the Font of Power , or bathe in the Pool of Knowledge ; however , they eventually disobeyed his orders , with the Son drinking from the Font , giving him the power of the dark side , while the Daughter bathed in the Pool , bestowing on her the power of the light side . The siblings then claimed areas of the jungle for themselves and started to fight each other , while the Father tried to keep the peace between them . The coming of Abeloth . One day , a young woman somehow came to their world . She initially became the Servant , serving and catering to the Ones ' needs ; however , she eventually became the Mother , doting on the Father and succeeding in mending the relationship between the Daughter and Son . She also managed to persuade the Son to use his destructive nature for a constructive purpose by using his Force lightning to carve new rooms in the walls of the gorge where they lived . However , she was still mortal and as a result she grew old , and was no longer able to keep the peace between the siblings . The ageless children started to resume their fighting , and neither the Mother nor the Father were able to prevent it . One day , while the three were fighting in the courtyard of their home , the Mother snuck a drink from the Font like the Son did , and quickly bathed in the Pool like the Daughter . The Father pulled her out with the Force , but it was too late . She ceased to be the Mother and became Abeloth , the Bringer of Chaos . Abeloth attacked both the Son and Daughter , forcing them to bow down to her . The Father then stepped in to save his children , afterwards taking them and leaving the planet , stranding Abeloth behind . The Daughter and Son then obtained the help of the Killiks , such as the Thuruht hive , by joining with their hive mind and lending them their power in the Force . Sharing their knowledge with the hives , the siblings directed the creation of Centerpoint Station , Sinkhole Station , and other devices to help create and maintain The Maw , which imprisoned Abeloth . Afterwards , the Father moved his family to the monolith - gated planet known as Mortis so that he might control them and keep the Force in balance . Thuruht stated that when the Current of the Force was altered and the flow of time changed ( the Current forced " where it could not be taken " ) , Abeloth was able to escape . She would stir up conflict and destruction each time , sending the galaxy into chaos and disorder , thriving on fear , death , and havoc , until the Son and Daughter returned to the Killiks , and together they would re - imprison her . This cycle would repeat itself periodically for hundreds of thousands of years . Xendor ' s visit . Approximately 24 , 500 BBY , the Darksider Xendor journeyed to Mortis and met the Ones . However , he believed their claims on the nature of the Force had no more or less legitimacy than the teachings of any other Force group . The arrival of the Chosen One . When the Father brought Jedi Knight Anakin Skywalker , Jedi Master Obi - Wan Kenobi , and Jedi Padawan Ahsoka Tano so that he might verify if Skywalker was the foretold Chosen One as prophecy held it , the Son attempted to kill his father with the Dagger of Mortis and remove him as an obstacle to escape from Mortis . However , the Daughter sacrificed herself , taking the blade for her father and causing the balance of the Force to come undone . The Son made another attempt to kill the Father shortly afterward , but was shocked when the Father suddenly stole the Dagger and stabbed himself with it , weakening the Son so that he could be killed by Skywalker . Moments after the Son ' s death , the Father himself died , disappearing into the Force . With this , the Ones were destroyed , and Mortis itself disappeared in a flash of light , leaving the Jedi returned to mere moments after they encountered the monolith , with no evidence that the planet or its inhabitants had ever existed . Legacy . During the return of Abeloth in 44 ABY , Grand Master Luke Skywalker — the son of the Chosen One — read the mission report in the Jedi Archives about his father and his mentor ' s experiences on Mortis . Combined with the information gathered from the Thuruht hive , Luke realized that his father ' s refusal to become the new Keeper of Balance had in fact set off a disastrous chain of events . With the death of the Ones , the galaxy began to slide into chaos ; the number of conflicts in the last 65 years were evidence enough of that . When Jacen Solo fell to the dark side and became the Sith Lord Darth Caedus in an effort to change the course of the future , he inadvertently set in motion another chain of events which culminated in the destruction of Centerpoint Station and the release of Abeloth . With the Ones dead , Abeloth was free to continue her rampage of chaos and destruction . After Abeloth ' s defeat at the hands of Luke and Darth Krayt , Luke believed that the Jedi and the Sith must become the new Ones : they must keep the Balance themselves .
