Wendy was raised by the female Dragon Grandeeney for some time. However, one day, along with other Dragons, Grandeeney suddenly disappeared and left Wendy alone. After wandering around trying to locate her lost mother, Wendy ran into Mystogan, who introduced himself to her as Jellal. Mystogan allowed her to travel with him, though he was also hopelessly lost on the road. One day, Wendy heard Mystogan utter something by the name of "Anima", and shortly after deemed it too dangerous for Wendy to travel with him further. He left her in the care of a close guild by the name of Cait Shelter, where she stayed until requested to aid the Allied Forces in their mission against the Oración Seis.
Back in her home, Lucy shared a good relationship with the staff in the estate as well as, presumably, her mother, until she passed away when Lucy was around the age of ten in the year X777. However, because her father was overly obsessed with his business and money, he had neglected his daughter, which eventually led her to run away from home just over a year before the beginning of the story.
