After throwing the Descendants of Tacitus out of Equestria and learning about the "Darkness Sisters", the Harmony Rangers deduce that they are dealing with something far worse. Princess Celestia tasks them to investigate while the princesses search for allies for the impending battle. But once the battle starts, the rangers find themselves in an enviroment known to humans... but unknown to ponies...

New threats and problems start to appear and Project Chrysalia enters its final phase... The long forgotten battle of the alicorn war for the whole of Equis is about to begin once more... And this time one world is not big enough for it.

* = Clop free
** = Slight clop for a few sentences.
*** = Heavy, explicit clop with intercourse for some paragraphs
Still, this is not clopfic. If you want to read clopfics, go elsewhere. Sex is part of this story, not dictating it.
