/ I have a kinda idea for Kora's back story.
Kora's parents Mard Geer and jackal lived their gild, they cherished her. But when they found out that Fairytail was suspicious of their survival, they left Kora in the Wyatt's door step, a sweet young couple. Taking her in they took her as their own, giving her the last name Wyatt. Kora loved them, and was honoured to have their last name, but that didn't stop her wanting to know and see her biological parents.
As she grew up, she would start to get jelouse of seeing kids with their biological parents, laughing and smiling. Her adoptive parents started ti get worried for her, and told her everything that was on a letter Mard geer and Jackal left for them. Feeling better she mentally forgave them. But she was still always on edge, and jelouse of the other kids.
When Kora turned 16 she set off on her own in search of her parents. It's not known till this day if she ever found them, or her sisters Kirai, and Jackie
What y'all think? Is it TOO detailed?
