At the heart of our vast universe stands a gigantic ash tree with a solid trunk and vigorous branches on which rest nine worlds. Its name: Yggdrasil. Friends, take your seats! On this cold winter night, Bjarni Olofsson, the wandering scalde of the North, has stopped at our door to tell us the story of these wonderful worlds where powerful gods, brave mortals and strange creatures live. Tremble at the wrath of Thór! Indignant at Loki’s tricks! Share the pain of Freyja! Fight on the plain of Brávellir ... but remember: dealing with the gods can be dangerous.
