Paranoia, Fear, call it what you will, it's all justified.

This story is set 6 months after the Canterlot wedding. A young pegasus named Comet Firehooves needs to learn to live and adapt in a rapidly changing world. As she makes friends with a runaway who joined the circus named Blade and a Pacifist called Cloud Cutter, the cities of Equestria are falling one by one to their new rulers.

Changelings, enhanced by new modern weaponry created by an odd pony named Zelmus using science and alchemy, are sweeping like a black cloud across the land of Equestria. With no troops to spare, Twilight Sparkle and Shining Armor hatch a plan to win the war once and for all.

"This is all those who fought…"
