According to the Republic, the Sith were extinguished from the galaxy at the end of the Great Galactic War, destroyed by a massive and unilateral campaign on the Empire at a moment of weakness. Yet, the Sith continued - returning the shadows, smaller, wounded and hurting from the great losses they experienced at the hands of the Republic. No longer controlling star systems, the Sith Remnant works quietly on a few coordinated planets, growing in silence, waiting for the moment that they can seek their revenge.
Independent from the Republic, the Jedi Order was forced to divorce itself from the galactic governance in the aftermath of the Great Galactic War. Foreseeing decades of trials and tribunals, the Jedi Order became an independent and unified Order, it was granted Dantooine as an independent within the newly established Jedi Reaches territory. Independent from any government, the Unified Jedi Order has the potential to act quickly and without the ease of government bureaucracy.
With the Empire gone and the Republic splintered, the worlds of the greater galaxy stand together in independence. They remain mostly untouched by the war, striving to move on and remain stable as a status quo established itself in the aftermath. However, despite all that, the Greater Galaxy's independence remains fragile - the Unified Jedi Order try to ensure peace and provide aid to those in need, while the Hutt Cartel continues to expand its borders and the Sith Remnant grows more ambitious as they try to re-establish their hold in the greater galaxy through subterfuge - wherein the many domains large and small in the Unknown Regions wait for those that could uncover their secrets.
