Have a little pic nic with the trolls when you find them. They have a little story to tell. Did you know that trolls began in Sweden? There is a little island between Sweden and Finland called Gotland. In the Gotland Sagas, during the 13th century, the island was controlled by the trolls. They sunk the island at night and brought it up during the day. Then a fellow by the name of Tjelvar came with his fire and chased the trolls away.
