Derpy Hooves is secretly a changeling.

Nopony particularly notices, or cares.

A cartoon pony named Twilight Sparkle visits me every other Friday night. Normally she just raids my fridge, questions my life choices, and forces me to watch her show. Tonight something is different. Has she always had wings?

Fair warning: Twilight’s views on her own fandom's creations aren’t exactly positive.

The story continues in the sequel

A Diamond Dog king, feeling bold after gathering an army of 100,000 dogs, decides the best way to flex his new muscles would be to invade Equestria for past perceived slights. As such, he sends a letter to Princess Celestia with a declaration of war.

It goes about as well as you'd expect.

After a long day, Octavia goes home and pours herself a stiff drink.
