I like what you’re doing here. It looks like you’re creating a chronology using the OT as your basis. It’s a neat idea.
Were the Sith being persecuted by the Jedi or just the Republic in general?
I like the idea of Palpatine not being a Sith. He strikes me as someone who is so egotistical that he wouldn’t hold allegiance to any religion or culture at all. He would see himself as above that sort of thing.
To be honest, I’m not totally sure about the name “Xim the Despot.” Maybe something a little more grandiose sounding. I’d like to hear more about his character, though.
That’s an interesting choice to have the Calamari as the second most developed species. I don’t remember which species has that position in canon, but I had assumed it was something like the Muuns or the Bith. I’m not an expert on that, though.
