Propheleus had enough of the Sith and the Jedi. To him, the were both equally flawed. The Jedi forced it's followers to deny themselves emotion, and the Sith encouraged their followers to embrace emotion for evil pursuits. The Gray Jedi were not innocent either. They forced people not persue the side of the force they wanted to, and their idea of balance was flawed, at least according to him. But what could he do? Create his own sect of Force Worship, that's what.
And so he spoke to the masses. Many would take his message of balance to their heart, others not so much. He soon gained to attention of the Jedi and the Sith, and attacks against his followers were not uncommon. Jedi who believed they were dangerous radicals who were pro Sith injured followers, while the Sith, who decided they were threat to their existence, killed or brutalized Proheleus' followers.
So they took to the stars. They purchased ships en masse and filled them with seeds and construction supplies. They took these ships out into the stars, to find a safe planet to call home. They flew past the territories of The Republic and The Sith, even past the outer rim, into uncharted territory. They soon found a safe planet. It was a good distance away from the territories, but close enough that they could access other planets should they need to. It was masked by other celestial bodies and in a sweet spot of habitability. They named this land 'Sanctuary' for the safety it brought these pilgrims. They found a plateau they could forge society on, it was elevated enough that they held a clear advantage in battle, but small enough that they could easily access it. Near it, was a mineral rich ravine, rich soil, a forest of trees, and a cave filled to the brim with Kyber Crystals. They named it 'The Covenant' and began to forge a society there.
They started by creating farms. The resources they brought, as well as wood native to the planet, made for easy barn raising. The soil took well to their seeds, fortunately, and was safe for the local livestock to feed from. These farms soon grew into a village, and government was needed. So they forged a town hall, and established a republican society. Religion followed soon after, creating a discipline of The Force that generations to come would follow. The citizens were encouraged to embrace their emotions and feelings, but to practice self discipline. Of course, some would skip on discipline and take what they wanted or needed by force. Thus, a guard was made, to protect the citizens of The Covenant, report on the situation in the galaxy, and keep peace.
Generations passed after the natural death or Propheleus, and by some miracle by The Force itself, no power vacuum was forged. His succsessors understood his message and continued to teach it, and encourage the growth of The Covenant. While it remained a primarily agricultural society, industry came alongside a local bartering economy.
They eventually created their own forms of Lightsabers, such as a Force Naginata. A slim pole, not unlike a Force Pike, with a Kyber Crystal powered blade with a curve to it. Their spears were also a weapon they were proud of. Again, it was a slim pole that had a blade at the end. Unlike the Naginata, this weapon was more focused on piercing and throwing, rather than the slashing and defense of the Naginata.
And despite their security, the future was uncertain. The scouts sent to report on the situation in the Galaxy consistently reported war. The Republic collapsing, the rise of The Empire, and the Galactic Civil War were all news The Covenant dreaded. Yet they remained obscure, but for how long will their paradise last?
A/N: This is just a one shot I made about an idea for a sect of The Jedi/Sith I had. I probably wont continue this, unless enough people encourage me to add more to it, in which case I will. If I do continue it, It'll be an OC story not connected to the main Star wars story line, picture it like Legends or soemthing. Hope you enjoyed!
