not agree with you, I think Anna is either Lucy's previous life, or Lucy herself after natsu having told her everything and she used the Elcipse gate twice ( the first to go to her mother and explain what will happen and her role, the second to go to 400 years ago, put everything in place and being sealed for 400 years maybe in a lacrima like Mavis )
