In the alicorn kingdom of Asgard, the story of the first Hearts and Hooves Day played out. We all know how the story ends. A dragon came. A kingdom fell. And Chaos reigned.
Comment-driven. Dragonfall, the worst city in Equestria, is in need of protection. The Sunheart Company, the worst mercenaries in the world, are the only ones willing to take the job. And then there's Lieutenant Agony, who is just the worst.
Twilight and Discord are a long way from home, and have to journey through a chaotic realm to get back to Equestria. Fortunately, this is Discord's speciality, so Twilight is in safe hands. Less fortunately, all the local gods want him dead.
Discord has had to give up a lot of his chaos in the name of friendship. In the interest of fairness, the forces of Order must also be made to surrender something.
How would a being like Discord want to be remembered after he's gone? Well, if you're curious, he did actually write a will. To the surprise of nobody, its contents are bizarre and mildly disturbing.
Lyra thinks Discord is an idiot for not thinking to dodge when the Elements of Harmony were about to strike him. Discord thinks this is the perfect opportunity for a game.
