I didn't quite understand the emphasized phrase. "Like in the first episode" of the movie? Or what? Besides, even if there wasn't an NK-47, there could have been an NK-1:rolleyes:
I mentioned Mark as an example, and besides, he couldn't have been responsible for all the Sith. So, I think it's unlikely that he killed all his colleagues, but he could have ruled them and given them orders. And besides, who knows how he died; maybe he was killed (for example, by our well-developed party).
Marka Ragnos ruled his entire life, outsmarting his enemies with the Force, turning them against each other, and after his death (I don't know who killed him or if he died on his own), they all clashed with each other for power, and only one survived. But in our version, you won't have to serve and try to kill the higher-up; you'll have freedom of action – you can take a teacher if you want, or you can choose not to, you can kill if you want, or you can choose not to.
