Incorrect. We are an extension of the Traveller, therefor any threats to the city and us effect the Traveller as well. If you are expecting magic space dragons to invade and eat the Traveller like an gumball, and the Traveller promptly turns into space RNGesus to save us all, this might be the wrong story you are playing. As for the stranger, yes, she is a holdover from the original weird story of the Traveller being evil and all that. Personally, she is not that important, although it would be nice to get her motivation and backstory. As for the Traveller not being in the story well. . . Got to tower. Spawn. Turn around. Look. Problem solved.
