Harry Potter and the awakened ancestry

Lily Potter, previously known as Lily Evans, was often told by her relatives that a curse, originally called the Zǔchuán Lìliàng curse (roughly translated into ancestral power curse), placed on their family and lineage was Chinese in origin and was only temporarily blocked and that it's either going to reawaken on it's own or that someone with magic from their lineage can accidentally, in an act of desperation to protect one of their own, force it to reawaken... Lily always hoped that she would never have to reawaken it herself...
After that Halloween night of 1981, both Lily and James Potter found themselves in a strange place that Lily instantly knew what it was... It took quite a bit of time for James to understand everything.

All the characters (except those that can be found in my character book) belong to J.K.Rowling as does the plot line from the original books.
