This is a side story to my Fallout Equestria fic, Trigger to Tomorrow. Crossfire, a notorious member of the Skull City Drifter's Guild, is a mare who only cares about caps and her next job. But who was she before that? How did she come to live in Skull City and call the Drifter's Guild home? This story shows this mares origins, focusing on her arrival in the Skull City Wasteland, and the events leading up to her appearance in Trigger to Tomorrow.
