Across this strange land of fantastic creatures, bizarre magics and legendary stories that is Equestria, an ancient darkness begins to stir, one that threatens to consume everything the three races of pony have worked towards. On top of their impending doom, civil unrest grips the country, as traitorous schemers fan the flames of a dangerously unstable border conflict, all the while threatening to steal the the crown from atop its ruler's head. And despite it all, through a bitter apathy towards the world and each other, the two great Sisters must unite their children, to deal with an unstoppable foe...

A crossover with George R.R. Martin's inestimable "A Song of Ice and Fire" series of books.
