Your project is really unbelievable! I can hardly wait to play it. This will add so much to a game that already is bursting from detail, depth and intense athmosphere.
Just a small idea: although you'd written that you wanted to use as a connection to your modules a landspeeder, but how about instead of using the small opening at the back of the cave with the renegade sithstudents? (Please excuse this broken English but I myself am from Germany, I unfortunately had to use a translation program.)
