First Force-worshiping order

"Ancient star maps recovered by the Jedi Knights of the Old Republic were believed to indicate the location of Rakata Prime. To them, they felt it might be the world they believed had been the home of a first order of Force worshipers predating the Jedi and Sith orders; who saw a unifying Force, neither light nor dark, but whole."

- Kirana Promenti

Before the Jedi and Sith formed their orders, a primeval first order of worshipers of the Force, also known as the First Order, were said to have made their home on the Unknown Regions planet of Rakata Prime. Following the Hundred-Year Darkness, the order's Force-adepts split into Jedi and Sith, and the order fell to ruin.

Description
"I told you that Darth Vader spent his life studying the ways of immortality in the Force. The ancient first order of Force-wielders did, as well."

- The Master, to Ben Solo

Part of a primeval first order pre-dating both Jedi and Sith religions, these Force-worshipers were said to see the Force as a unifying whole rather than split into light and dark sides, and studied the ways of immortality in the Force. The Wise Master was claimed to have control over the Force and the midi-chlorians to create life.

History
In the time before the Jedi Order and the Sith emerged, Force-worshipers were said to have formed a first order on Rakata Prime, where they saw a unifying Force rather than light or dark sides. These ancient Force-wielders studied the ways of immortality in the Force. The Wise Master was a member of the primeval order, and claimed to have created life. She was said to have the brute strength to control the Force and to twist and command the midi-chlorians, though her creations were believed to be abominations with no free will. She planned to populate the galaxy with her soulless beings, cut off from access to the Force save for what she doled out to them, creating a peaceful society of orderly, compliant, yet droid-like beings.

The first order eventually fell to ruin on Rakata Prime, and after the Hundred-Year Darkness its Force-adepts split into the Jedi and Sith.

Legacy
"I can show you the ways of the Force&mdash;and together, we can forge a new order, an order of knights devoted to the entirety of the Force just as the first order of Force-wielders did, and a military force who will be able to implement any objective set by their supreme leader."

- The Master, to Ben Solo

The Jedi who split from the first order established the first Jedi temple on Ahch-To]]. Jedi Knights of the Old Republic later recovered ancient star maps believed to indicate the location of Rakata Prime, feeling it was the homeworld of the so-called first order of Force worshipers predating their order. The Sith venerated the Wise Master, though the Jedi believed her creations to have been abominations.

Luke Skywalker and Lor San Tekka discovered records of the ancient Force-wielders, and learned of their studies into immortality. Luke taught the parable of the Wise Master to his student, Ben Solo, though the troubled young man took the opposite meaning, and later discussed the first order with the entity calling itself the Master. Solo was swayed by the entity's words, and the Master attempted to recruit him to create a new order of knights devoted to the entirety of the Force as the first order was.

Following the massacre of his Jedi, Skywalker was believed to be retracing the steps of the earliest Jedi, and visited Rakata Prime. Kirana Promenti, one of the Knights of Ren, was tasked with following Luke's path in order to discover hints to his current whereabouts, and joined a venture to Rakata Prime undertaken by the Dowutin big-game hunter Grummgar and the Twi'lek scholar Ardanna Glie. While exploring the unknown world, Promenti discussed its first order of Force-worshipers to Grummgar and Glie.
