-I was actually toying with the possibility of this Bracknell Sith Lord dude we'd kinda had as a WIP background character being one of the True Sith's plants on Korriban, perhaps he somehow has quite an influencial role in the Senate as well and is one of the main driving forces of their attempt to de-stablize the governments? Turning young Sith initiates more towards the True Sith's goals and secretly amassing a kind of secret task force to work for him against the current Sith Order to further destablize it and screw with the Republic's view on Force sensitives by setting them 'missions' to gain prestige where they would have to assassinate (or even just fear-monger) with various high influence Republic personell?

-I haven't gotten as far as Knights of the Fallen Empire yet (STILL stuck on Tython lmao) but the idea of the remaining Republic/Empire sympathisers left having to band together to help each other to defeat the new threat sounds AWESOME! O: I could see conflicts breaking out in the Dark Council naturally anyways due to the "kill-or-be-killed" and "every man for himself" mantras taught by the Sith Order as is (particularly I don't see Aria's dad liking Bracknell, AT ALL xD Perhaps they could have some kind of rivalry thing going on starting from when they first initiated into the Sith Order that gradually builds until the conflict actually pulls the Dark Council apart between Bracknell supporters (who end up siding with the True Sith's viewpoints) vs. Aria's dad's supporters (who are more in line with the "current" Sith beliefs?)

-LOVING the idea about Aria and Yerbol being imprisoned on Tython (or whichever other planet we're gonna hold the meeting on lol) for a while and having to escape to go and get Aria's dad (or, alternatively, (though I'd have to figure out a plausible reason since he's kinda an asshole and he probably wouldn't really do it just to protect her XD) perhaps her dad could somehow find out that they're imprisoned and potentially could get himself across there to help break them out somehow? IDK that's kinda a spur of the moment idea I had but it could be interesting if we could pull it off lol)
