Rarity is not a pony to get her hooves dirty, but when it comes to her sister, she can make an exception. So when the Diamond Dogs kidnap Sweetie Belle and try to blackmail her, she is determined not to take it lying down. Wallowing in melodrama, maybe. But certainly not lying down.
Little does she know that while putting their plan into action, the Diamond Dogs manage to get mixed up with a creature nastier than they are. A creature that may spell doom for Equestria if it has its way...
Part I of the Orthrus Trilogy.
