Fairy Tail and the Light Sword

Lucy Heartfilia went to the Fairy Tail guild like every other day but felt a bit sick. Despite that, she decides to go on a mission with the rest of team Natsu.
Once they arrive, they are told to go look for and investigate a mysterious sword. While Natsu and the rest get sent flying into a wall trying to touch the sword, a voice in Lucy's head kept telling her to pick it up. Once she does she falls unconscious right before 100 shadow creatures appear leaving everyone to fight them.
When Lucy wakes up she starts to wonder who she was and why the sword only answers to her. As she slowly but surely finds her answers will a new power awaken in her? Will she be targeted for it? If so will she be able to protect her family or turn tail and run to save her own skin? Follow Lucy, Natsu and everyone else as they meet people friends and foe alike to find the answers they're looking for.
