The traveler could just be using us for an unknown purpose, during a fallen attack on the city, the traveler tried to leave and we crippled it, when it left the fallen they let it leave but now are doing anything in their power to get it back or maybe get back at it? Maybe the fallen realised they were being used? And would humanities enemies be here if the traveler wasn’t?Just think about, are the fallen evil? or is the traveler the bad one? or are all of us?
