It’s the end of the world as we know it... or is it?

WHAT'S THE STORY BEHIND MADDIE & HER FRIENDS?

Deep below the earth’s crust sits a long-forgotten citadel of the old ones, the horrific contents locked away in the stone walls until their seals are broken - the steeds of Pestilence, Famine, War and Death all await their true calling, to bring about Earth’s final destiny. Of course, hundreds of years sealed in a proverbial ‘Pandora’s Box’ is bound to bore even the most destructive cosmic forces, and after hundreds of close calls, the originals have decided to pass on their mantles to a new generation of end-bringing steeds - their children. 

In order to ensure that these offspring grow up to be the most potent force for destruction, the original horsemen employed the help of Maddie, the youngest old one, to serve as a babysitter for the new generation, and ensure that they do not get too attached to the mortal world. However, some things manage to slip through the cracks, and now she has to deal with four incredibly powerful angsty teenagers, and try to guide them to their destinies.
