The Sith Eternal Cultists are one of the non-playable characters in Lego Dimensions 2: The Rise of Enoch, from the Star Wars franchise.
At some unknown point, the Sith Eternal cult arose and took up residence in the Sith Citadel on Exegol. They assisted the resurrected Darth Sidious in creating Snoke—who would go on to become the Supreme Leader of the First Order—with various dark side rituals. They also played a part in the creation of the Sith Eternal fleet and the Final Order, which was meant to revive the Sith Empire and restore Sith rule to the galaxy. However, many members of the cult were killed in 35 ABY when the Jedi Rey, the granddaughter of Sidious, destroyed the Citadel.
