Check this blog for reasons why this story is now on hiatus.

The three fillies of our story are so desperate to get their Cutie Marks that they've formed the not-so-secret secret society, the Cutie Mark Crusaders. After having Crusaded around their hometown of Ponyville, they turn their sights to the wonders beyond (even if traveling by themselves gets them in trouble with their sisters).

But outside of their not-so-peaceful peaceful town, they find that not everything is as wonderful as it seems and they very well may be the only ones who can do something about it (along with help from a couple of new friends).

Follow the Cutie Mark Crusaders as they search for their special talents but end up finding more about themselves and each other than they ever imagined, in the exciting Adventures of the Cutie Mark Crusaders - Fillies on a Mission!

This, if you haven't noticed, is a long story. There is still much more to come as well. There are a lot of slice of life stuff at the start, but not all adventure stories start off with loud explosions and huge disasters; the girls have a long journey of discovery ahead of them and not all of it promises to be nice quiet little things. Also, the alternate tag is for the fact that they will get their cutie marks, eventually; and the crossover tag is in case some of the references I plan to do is too much for a 'normal' story.

A huge thanks goes to Gwg who helped collaborate this with me as well as editing and proofreading the chapters
