Princess Lenya Thex can be found in some out of the way places, and plays an important role in the quest for the Silent Watch Shield, and the quest for the Thex Dagger. When greeted, you'll notice that she speaks a very similar line to that of Princess Leia from Star Wars:
You say, 'Hail, Princess Lenya Thex'
Princes Lenya Thex says 'Are not you a little short for a Highpass Guard?'
[Luke, dressed as a storm trooper, opens the door to Leia's detention cell.]
Princess Leia Organa says 'Aren't you a little short for a storm trooper?'
