Remembering all over again

A year after her mysterious disappearance, everyone in the guild had turned back to normal. Although they still hold that burden in their hearts. In that year, Gray and Juvia became a couple, finding love in the comfort they offered each other. On a messenger mission they come over a shrine for the ice goddess, Elsa. Its guardian and head priest are found having tea on its territorial boundaries.

What happens when the guard is Lucy?!

She doesn't remember anything from her past, just that the old priest is her 'grandfather'. She only knows about her ice magic and will only let the ice Mage pass to the shrine. After a large debate about letting they others through, the priest comes out and allows them all in.

Will she ever remember her real past?
