Fight for your freedom[COMPLETED]

After a traumatic event, no one was the same. Fairytail disbanded for a whole three years. No one went out of their way to bring everyone back until natsu returned to find it gone. He spent a year looking for everyone and soon the guild was back. Except one person. Lucky Lucy Heartfilia.
It's been four whole years since many people have even heard her name, she vanished but there's a reason. She trained in a magic her mother failed to teach her, seeing how she did die. Lucy was taught many things, how to fight hand to hand, use different weapons, other magics. One overpowered the rest though. It's called Third Blood.
This magic is wanted by dark mages for one reason. It can resurrect the dead and help you heal your wounds. It's a magic that only some can weld, those who failed to learn the magic correctly have lost their lives trying.
Lucy starts making appearances but she isn't the same. Tattoos cover her, scars, dressed in black, black demonic markings on her body. A single black eye. She's changed but what everyone soon wonders. For the better or for the worse
