A Heart that Promises

Her grave stands high, the symbol of a key was deeply engraved in the middle, her name just below it. It's been three years since her death, three years since she took a job without her team. Lucy Heartfilia had hoped that she could finally prove that she wasn't as weak as everyone thought.

Bloody keys were sent to the guild, a note attached. She had been murdered by a dark guild on her journey, now the keys are locked away, none of the spirits dared go with another wizard. Years go by and very few people are still grieving, the ones that still are place flowers on her grave every day, only to find that the flowers ware frozen short after. Things have changed, Lisanna took her spot on team Natsu, Gray went into a depression, and Natsu is brainwashed, no longer able to sense an enemy. She has changed to, Lucy just might not be dead, maybe she became stronger, maybe she will back and figure out what's going on. Someone has betrayed Fairy Tail, slowly taking down the wizards. Can she finally come out of hiding and assemble Team Natsu once more?
