Sunset Shimmer had grand ambitions upon becoming Freeport's only magus, most importantly helping out the citizens of Freeport itself. When she hears of an outlying farming community in danger from a horde of undead, she knows she has to help them. Even if they can't pay her fees, it's the right thing to do.

However, this new challenge might be too much for her to handle. These zombies are unlike anything she's ever seen, and an old enemy is mixed up in the middle of all of this. Sunset has no idea what dark secrets the undead horde hides, or the danger posed by the necromancer behind it.
