I see our famous and dead John Bauer who drowned with his whole family in Vättern which is a long and narrow lake in Sweden. He was standing between Vättern and Värnen. It is said that a giant took his fist and threw it into the Baltic Sea and it became Öland and likewise Värnen which became Gottland. Are you Swedish? Considering the trolls.
I'm from Denmark, but lived a couple of years in Sweden when I was a wee kid. John Bauer reproductions were hanging in every other house in Sweden back then :)
