When Applejack dies giving birth to Mac's incest twins, Twilight leaves her in a shallow grave and takes the twins home. She intends to breed them with one another to learn more about extreme incest, but her experiments cause a chain reaction that results in a lot of bad things happening to many deserving and some undeserving ponies.

Oh and you find out Derpy's final fate. Eventually.

Contains ridiculously out-of-character characters. This is by design, as the commissioner (dio-drogynous) wanted them to have the same types of personalities as in “Derpy’s Finest Hour”. So I figured, why not just toss it into that world entirely!

EmberArts wrote a story that happens in the same universe, though I'll call it a different timeline since some of the events in it contradict.
