In the Kingdom of Arthwen, there was a very unusual shop. It wasn't on the high street; it was deep in the forest. It wasn't in a building; it was inside a tree. It didn't sell food, or clothes, or toys: this shop sold potions. Tibben wants to be the Potions Master one day, just like Grandpa, but for now he is an Apprentice and there is lots to learn!
