King Alexander XI is dead, and without heir.
Your parents want you to be that heir. Luckily for you, there's totally an ancient tradition for electing a new ruler in times like these: simply lock eight children of royal blood (or the closest thing) in Castle Elsinore, complete with the ghosts of past rulers, and let them manipulate the living heck out of each other and the local population! Two shall rise above the rest: King and Queen (or Queen/Queen, King/King, King/Nobody, Queen/Nobody)! Everyone else that is still alive gets to go home! It's a win-win for everyone (except those that died)!
