Creatures of all kinds are attacking Equestria and the princesses's combined magic can only hold off so many attacks for so long. The Mane 6 must bring myth to life and find the legendary Star Knights in the unknown beyond Equestrian borders before Equestria falls. Meanwhile, Derpy discovers shocking secrets of her own. What she does with her newly-discovered, deep, dark secrets will decide the fate of Equestria's future. Could this be the end of Equestria? Will the Mane 6, Derpy Hooves, and Spike be able to save Equestria in time? Will the Star Knights join their side and help end the war in victory? Will Derpy make the right decision? This is only the beginning. There might be more power behind enemy lines than what is known...

Hi, everyone! This is my first MLP fanfiction and my first attempt at a crossover story. I hope you all like it! Also, if anyone has any suggestions for worlds to "crossover" in my story, I'm open to ideas! Thanks for your comments and for reading my story!
Pretty good

Wait, so is this a mega/multi-crossover?
.........Now, while I would automatically suggest the Nasuverse due to it having many badass characters with interesting and well-developed personalities, awesome magic that actually has a system, an immortal wizard who can already pop into any given universe at a whim, and many other great things......... it is generally waaaaay too complex for someone who isn't a devoted fan to write about while doing it proper credit.
Also, the characters in it are too powerful/dangerous for any MLP:FiM fanfiction with remotely canon-like attributes.
Still, if you're interested despite that, I am willing to provide ample information about it.
Right into the action I like it
