So what type of senate was in the SWTOR? Was it the Galactic Senate?

So in Old Republic Lore, would the Galactic Republic and Sith Empire be one thing? or were they separate? To like explain what I'm asking i'll go in depth. Would the Galactic Republic Senators and Imperial Senators be in the same room and they all have one Supreme Chancellor OR Would the Republic have their own Senate dedicated to only Republic Senators and vise versa.

How does anyone beat this guy, I simply can't get past him no matter what. I have Lana set to healing and solo fighting one of the big guys off to the side and the boss and other big guy with me but I die instantly, I stand in the circle, die in 5 seconds, i stand super far away and kite from the circle, die. I simply cannot do it no matter what. Any tips? Edit: I'm a level 70 Merc

Thank you for the advice, i'll keep this in mind on my run back. I believe that I actually did get the scene correct just didn't click the right button in the cantina scene. Sucks that I messed it up on my main character but oh well.

It did seem odd that I never got any more flirts with her, or if I did it was SUPER rare. I guess i'll just do it on an alternate character instead. Cause I know they released some mission regarding fixing it but it probably doesn't apply if it was never set in the first place.

So I recently just finished The Nathema Conspiracy mission and I've read everyone say they get the option to marry Lana but I never got that. Some clarification, I have picked everyone flirt option and all with Lana and no one else, so I don't know if I did something wrong or such? Any help please Edit: It never gave me the choice to lock-in romance with Lana in Chapter 9 of KotFE
