Fallanassi

The Fallanassi were a religious order that were adept in using the Force to create a projection of themselves that could appear anywhere in the galaxy. This technique was chronicled by ancient Jedi masters in the sacred texts and called Similfuturus. The technique required the user to pour their life essence itself into the Cosmic Force. The technique was used by Luke Skywalker at the Battle of Crait to give the Resistance time to escape the First Order. Luke gave his life to complete the projection, after which he disappeared into the Force.

Behind the Scenes
The Fallanassi were first mentioned in Star Wars canon in the reference book Star Wars: The Rise of Skywalker: The Visual Dictionary, a tie-in book to Star Wars Episode IX: The Rise of Skywalker. The Fallanassi were first created for the legends novel trilogy The Black Fleet Crisis, where they exhibited similar projection abilities. Author Pablo Hidalgo apparently saw the similarity between the ability used by Luke in Star Wars: Episode VIII The Last Jedi and the ability in the novel series, and connected them in the reference book.
