I mentionned it briefly in the dragon post but in the AU Nightmare took over, the monsters are slaves to human. It is the choice the king made about them after the Great War. Even the poorest human is higher in statue than a monster. But then, the self proclaimed king of negativity came and for some, it was a delivrance! After all, he's a monster....right? Little did they know that Nightmare did not care about their situation one little bit. The major part of the population was turned into mindless shadows, the aristocracy, decimated. for the castle's servants who remained, it didn't change much about their situation minus the negativity that is now crushing them.
