Brandish found her and after learning the truth of her mother's death and seeing Lucy's power and sadness, invites her to join the Spriggan 12. Lucy accepts. There she meets Invel and remember a promise she had made him before she joined Fairy Tail. LucyxInvel
Seal unleashed
Lucy sobbed into her pillow. Fairy Tail had been disbanded in the aftermath of Tartaros. Not only had she lost her oldest spirit but she had also lost her family.
WHY? WHY? We are fought so hard and sacrifice so much. And all for what? For our home to be taken from us after all that.
Her eyes landed on Aquarius' key. I sacrificed Aquarius' key to save my home. But now it's gone away. Picking up Aquarius' key she thought "If Fairy Tail's gone, what's the point? What's the point of my sacrifice? I may as well have just let everyone stand captive in Cube. At least then I would still have Aquarius. Lucy bolted straight up. No I don't mean that. Now that Tartarous is destroyed everyone in Fiore will be safe from these demons. Lucy felled back on her pillow. But still I wished I had Aquarius' key. If only I had been stronger, if only… Lucy's thoughts trailed off, as she noticed that she was beginning to glow. Lucy screams as she felt as though her insides were being ripped apart. The pain was several times greater than when she had her second origin unlocked.
In the ruins of Fairy Tail's guild hall, the First Master turns toward Lucy's apartment. "The seal is being destroyed."
Lucy kept screaming for an hour. The pain starts to subside after that. It stops completely after two hours. Lucy shakily pushes herself up. "What was that?"
"That was your power and memories returning to you." Lucy looked up to see Mavis floating in the air.
"What did you mean, First Master?"
"During the seven years you were asleep, Zeref trained your mind. When you awake, the power and experiences will have merged with your body. However I prevent that from happening. I thought that will be harmful to you because I wasn't sure if you receive a portion of his power or not. But now I see that he just help you increase it."
"Why didn't you unlock during the battle across Tartaros?"
"I wasn't sure if that will help or just make things worse. Zeref could have manipulated you to help his demons.
Lucy sighed. She knew that First Master had meant no harm and besides she was too tired to care.
"I see. Can you go away so I can get some rest?"
"Okay. And don't worry about your neighbors. I put up a soundproof barrier around your apartment." Lucy nodded her thanks and let her head fall on to her pillow (after flipping it over). She fall asleep instantly in unaware that this was just the beginning of a new chapter in her life. Unaware that the next week will be a whirlwind and her family's past will grant her new happiness.
Sorry, if it wasn't that good. I wrote it at 12am. The next chapter is when Brandish arrives.
