Twilight sparkle is going to learn that not everyone in Equestria is nice, perticly, the two head Generals, who she has to spend the day with. Leaning that the elements aren't the only line of defense Equestria has. And that there is more to the world than friendship. Secrets and split blood litter Equestrias history, and the two Generals who may be more than they appear.
A reality check with a brutal night General, and the serious day General. No sugar here.
