Lucy is lost and is found by Acnologia. She becomes a dragon slayer and joins Sabertooth, but there is one problem, she is blind. In this story, Sting, Rogue, Gray, and Natsu are one year older than Lucy, with Laxus still being six years older. Also everyone else stayed the same with their age changing to be in accordance with Natsu. Like Erza is still two years older than Lucy with Wendy still being five years younger than Lucy. I don't own Fairy Tail. Also there are spoilers.

Lucy Dreyar comes home after half a year. She comes home to a brother with a huge sister complex and with the most powerful being on Earthland.

Lucy leaves Fairy Tail, but not in the way you think. It went this way, Fairy Tail went to Tenjinrou but Lucy was left behind. She left the guild because she couldn't bear with the sadness of everyone leaving her. The group comes back and doesn't find Lucy but meets Alice, who seems very familiar. The original idea of the story comes from Down the Rabbit Holes, Fanfiction.net.
