[[WMG: Cabal will eventually succeed in resurrecting the mysterious girl but with disastrous consequences]]
She will return to life but not as the person she once was but as some [[CameBackWrong corrupt Death Goddess]] who will be hell bent on ending the world forcing Cabal to put her down with the help of Leonie Barrow and (hopefully Horst, if he ever [[spoiler: magically comes back from the dead, too]]).

It would be hard to believe that [[spoiler: Horst is actually [[BackfromtheDead dead]]]] given what happens at the end of The Fear Institute.
