Beyond oz

Lost in an endless milestone of sand, the young wicked witch of the west elphaba Thropp keeps telling herself there's no place like home.
But how can she ever find home when it feels like it does not exist.
Elphaba's lover fiyero is dealing with becoming a human reversed from his straw state and suddenly able to feel the heat of the situation collapsing around him once again.
Meanwhile Glinda the good now ruler of Oz deals with accepting her lonely state and the way that she is, until a mysterious cloaked figure enters the palace and plans to take that freedom away from her.
Can Glinda get help from fiyero and elphaba to stop this mysterious new villan from taking over all of Oz? Or are some things better left alone rather than resolved.
This fanfiction takes place directly after wicked: for good the movie.
