Three ponies, none of any special abilities, during a simple dance show, chance upon somepony unheard of to the normal life. And as their life begins to unravel at the seams, assassinations are slowly taking place, nobles are dying, the rich are mysteriously vanishing, only to wind up somewhere else, dead. Entire villages froze over for months on end, only to melt and everypony missing. The four Princesses have no idea what to do, and the environment is spiraling down- not only the random snow falls, but the seasons were changing slowly, as if something was stopping it from happening.
In the middle of it all, was 'Lady P', leading her band of misfits and undesirables against the Princesses, the nobles, and all of Equestria.
