JFYI, there are apparently two Sith, one is Avreet and the other one is the guy Hanson is aiming at. Also, I don't think your character would know Avreet is there, as my fish is using Force cloak that makes him invisible and your character doesn't have Force sense listed in his powers, so I don't think he would be able to feel my character through the Force either.
Just so you are aware, Geonosis is an ally of the Mandalorian Clans. Most of the galaxy knows that, so taking any action against them will have severe consequences.
