Dunwyn is an ancient castle located somewhere in the modern-day United Kingdom.
The high priests of Castle Dunwyn learned alchemy from a group of magical creatures, known as the Great Ones, living in a glen near Dunwyn. They recorded the lore in a Great Book, including a recipe of a potion brewed from colorful berries that gave people the ability to bounce high in the air.
In the 1960s, a page of the Great Book was found and was sold at an auction in London. The criminal organization F.O.W.L. sent their agent Black Heron to purchase the page. In response, spy agency S.H.U.S.H. sent their spy, Agent 22, along with billionaire Scrooge McDuck, to the auction. Black Heron managed to get hold of the page due to Scrooge's reluctance to bid for it, but Scrooge and Agent 22 found Black Heron's lair and stopped her from creating the potion.
