Characters/Prologue

Maleficent and Hades didn't only have Mal, they also had a boy, Mal's twin brother Hayden. When Hades and Maleficent went their separate ways they each took one kid, it was evident who had who's powers so they each took the one that had their powers, Hades took Hayden and Maleficent took Mal. The two were close but no one knew they were siblings, and they didn't ask about the other's parent, it was like a little rule or pact they had, they were friends but not siblings unless they were alone and that happened very rarely. So when the two are chosen to go to Auradon and they both find someone they like.. what happens then?
