(Human tag is their because their is one human in the story. I admit the first two chapters suck, I was just getting warmed up… chapters after that will be allot better.)
Beings from another world arrive in Equestria and bring their darkness with them. Celestia quickly finds herself falling for one of them. Chrysalis is planning an invasion. And Stardust and his small band of misfit otherworldly friends are all that stand between Equestria and destruction… though lets be honest, if they never came the changelings would be all Equestria would have to worry about… none of the other dark things that followed them. And we all know the princesses can handle changelings…

So I guess the other-worldly beings are making it… worse?

What could else could possibly go wrong?
