''From slavery rises the most powerful Sith in generations.''

Originally, I wanted to play through the Sith Inquisitor storyline myself and upload the scene from my own gameplay, but I did not really find the time to do such, and I don't believe I will for the coming months. I am not quite a speedrunner, sadly.
I thought about making the Sith Inquisitor a female human due to it making the most sense story-wise. A human being a slave in the Sith Empire is possible, and the Ancestor Kallig being humanoid (without tendrils or the likes) would make the Sith Inquisitor likely to be at least somewhat human as well.
Furthermore, Zash, a female human Sith, wanted the apprentice as her new body. So I think it would be fair to assume that the Sith Inquisitor was also a female human.
I also thought about making the SI more light-sided, eventually leading to Darth Imperius, as if I remember correctly, it's the 'base' name that is given when starting KOTFE, as the Sith Inquisitor, without playing through the Inquisitor's story.
Perhaps, if I do find time, I could upload my own version sometime in the future anyway.
