Out of the blue, an attack on every major city in Equestria, and some non major cities, by an organized, secretive group of unicorns leads to some questions being asked by the non-magic wielding users of Equestria, and sparks high tensions between the different groups. These tensions threaten to start an all out civil war.

Twilight Sparkle and her friends are called upon to help stop this threat, but will they be able to come together, or will these tensions tear them apart as well?

(I sort of took this idea from another story I read once, but it wasn't well received and I can't find it again. Also, I don't know what to do for cover art, lol. One more thing, this story is subject to having its ratings and categories changed once I figure out a main direction for where I want to take this story)
