If you have read the Fairy Tail Manga Spoiler but Mavis used a forbidden black magic spell ran away after Yury (Makarov's father) wife (Makarov's mother) died, she finds Zeref and falls in love. Great Right, WRONG when Zeref fell in love with her she died then he took her back to Fairy Tail and that is how she became the enternal magic Fairy Heart
