Alright, here we go *cracks knuckles* 

So Yerbol and Aria get offworld, rescue an assortment of Jedi and Sith, then manage to get to a hideout. I assume it would be Wild Space? That might be too close to the Sith homeworld, but you get the point, somewhere remote where the Sith couldn't find them. I feel like it wouldn't take much effort to unite this band of Jedi and Sith together, seeing as they have one common enemy. I'm assuming there would be some dust-ups here and there, but nothing that couldn't be sorted out. This alliance would recruit and grow, building up a sizable resistance against the True Sith, who would be murdering every Force User in sight with the combined efforts of the Republic and Sith. 
I assume some within the Republic and Empire would disagree with mass genocide and join the resistance, which would lead to an eventual standoff between the resistance and the True Sith. Bracknell and co. are dispatched, schemes exposed and everyone duped feels like an idiot. 

HOWEVER

The motivating force behind the True Sith, the one pulling the strings, is still alive. He communicates with Yerbol and Aria, summoning them to a remote moon in Wild Space where he attempts to reason with them. His premise is that the Force has been pulled apart by the division of light and dark. As the only remaining True Sith Master alive, he has perfected the ultimate balance between the two halves, effectively giving him true mastery of the Force. However, with repeated collapses of both Jedi and Sith orders, he felt drastic action needed to be taken. By the simple act of eliminating Force users, he argues, the Force becomes unbalanced, to the point where it cannot sustain even itself. Although he is fully aware that "killing" the Force through genocide was a dramatic move, it felt it was necessary. However, Yerbol and Aria's efforts caught his attention; after all, they were the ONLY two to pass the trials successfully in almost a thousand years. They have the potential to begin balancing the Force, to give true enlightenment to all those given the gift of the Force. He offers to train them in the most rudimentary of concepts before sending them back with the teachings he has assembled. IF Yerbol and Aria agreed, they would train under him for a short period of time and go back to known space, only to be promptly rejected by both Jedi and Sith Masters, who are already beginning to descend into infighting. A small contingent of younger Jedi and Sith who fought alongside the duo seem intrigued and are willing to learn. This brands Yerbol and Aria as heretics who are not welcome on either planet nor by the Republic and the Empire, who are beginning to consolidate their assets to merge into a powerful sociopolitical force. 

With the massive changes underway in the galaxy, other systems were bound to take notice. Fleets of unknown origin begin to probe the very edges of known space before zipping back into hyperspace. No one can figure out where these fleets came from, but their increasing appearances are making the newly founded government very, very nervous. 

So, what do you think?
