Spoiler:

Anna was a celestial Spirit magic user 400 years ago who opened the Eclipse gate to send the dragon slayers into the future where Layla opened the gate in present time. We don't know if she's an ancestor of Layla or how Zeref and the dragons and Anna met. But she helped the dragons and the slayers to be transported to the future on July 7, X777
