@fangirl_jw I'm not the expert on Sith, but they seem to like galactic domination. Wookieepedia would have more and I would suggest reading up on it there. In the movies we had the rule of two. Master and apprentice, but in the past there were brotherhoods of Sith and in the future Darth Krayt has a bunch of Sith working for him. I never heard of them being in the sex trade, but slave labor seemed to be popular with Palpatine.
