Prince Barnaby and Princess Agnetha live in Marbleglow Palace - right in the centre of Marbleglow - the Capital City of the Skylands.

They had both lived in the palace since they were children, and it had been the perfect place to grow up - with hundreds of rooms to explore, and huge kitchens and cellars, and a garden as big as a park.

But now that they were all grown up, they found they didn’t play at all. And that meant - they realized one breakfast time as the rain dribbled down the windows - that they were bored.
