Abeloth is one of the non-playable characters in LEGO DImensions 2: The Rise of Enoch, from the Star Wars franchise.
Abeloth, also known as the Bringer of Chaos and Beloved Queen of the Stars, was a being very powerful in both the dark side of the Force and the light side of the Force because she drank from the Well of Power and bathed in the Pool of Knowledge. She first lived as the Servant, a mortal woman who served the powerful Ones on an unknown jungle planet over a hundred thousand years before the Battle of Yavin. Over the course of her life, she became the Mother: she kept the peace between the Father's warring Son and Daughter and became a loving part of the family. But she was still mortal—she grew old while her ageless family lived on—and she feared she would lose her precious family. In a desperate attempt to hold onto the life she so loved, she drank from the Font of Power and bathed in the Pool of Knowledge. Her actions corrupted her, transforming the Mother into the twisted, immortal entity known as Abeloth.
When the Father discovered her crime, he departed the planet with his children and left Abeloth stranded. The Son and the Daughter enlisted the help of the Killik hives from Alderaan, using them as workers to create massive technological artifacts, such as Centerpoint Station and Sinkhole Station to imprison Abeloth. According to the Killik Thuruht hive, Abeloth managed to escape her prison whenever the Current of the Force was altered and the flow of time changed. Each time she escaped, the Son and the Daughter would return to the Killiks and defeat Abeloth, locking her back in her prison. This cycle repeated itself for thousands of years, until the death of the Ones in 21 BBY.
When Jacen Solo fell to the dark side in 40 ABY and became the Sith Lord Darth Caedus in an attempt to change the future, he unintentionally awoke Abeloth. She later managed to escape from her prison due to the destruction of Centerpoint Station during Caedus' reign. Taking advantage of the chaos the galaxy was in, she immediately sought to maximize its effect, to totally wipe out civilization. However, she was discovered and hunted down by Luke Skywalker and his son, who constantly fought her and even destroyed some of her avatars. Ultimately Abeloth took the form of Senator Rokari Kem and successfully got herself elected as Chief of State of the Galactic Alliance. However, her remaining avatar bodies were killed and she was then destroyed by Luke Skywalker and Darth Krayt in the realm of Beyond shadows. Despite her death, Luke and the Jedi were not convinced Abeloth was dead for good and thus began searching for the planet Mortis. Luke intended to locate and obtain the same dagger used to kill The Ones decades earlier during his father's own encounter with them, to ensure that if Abeloth eventually returned, the Jedi would have a way to permanently kill her.
