The castle is in the Kingdom of Dunwyn, and is ruled by the benevolent King Gregor.
The medieval castle is filled with hundreds of people who live and work insisde its stronghold walls. Among them are Princess Calla, the page Cavin, the squire Unwin, and the knight Sir Tuxford.
The castle is protected by the Gummi GlenGummies; although most of its people are even unaware of their existence. The latest report of a Gummi Bear sighting is over 500 years old, which is why the mystical creatures have since been relegated to fairy tale lore.
