Sally and her sister were abducted shortly after the Great War, making her over 200 years old. Her parents were killed almost immediately after the war. After the abduction, the girls were separated, and Sally never learned that her sister died during one of the aliens' many experiments. Now a fixture in the lower levels of Zeta, Sally has repeatedly escaped custody and explored a fairly large portion of the ship's lower level. She has a degree of insight into the workings of the mothership and the motives of the aliens that nobody else possesses. Sally also offers random alien items once every few hours, should the Lone Wanderer request them.
After completion of the quests, Sally stays aboard the alien starship and scrounges for materials. The player can return to the starship at any point and ask if she's found anything, and, if she has, she will give the items away. This interaction can be manipulated the same way random encounters can be manipulated. The player can also simply wait 24 hours and ask her again, and she will give away more items.
