In the beginning there were only native forests and wasteland. The Aesirs, one main group of Norse gods, cleared places to stay, both for themselves and the humans. They named the humans home Midgard – because it is placed in the middle of the world. And in the middle of Midgard – so that the humans should not feel lonely and abandoned – the gods built a place for themselves: Asgard.\r

Asgard is a huge castle surrounded by thick walls. To get there you have to ride over the rainbow Bifrost. Strong defenses were built around Midgard as protection against the wild and unknown outside where dark and sinister forces are raging. There – in Utgard and Jotunheim – giants and trolls live. Everything is arranged like tree-rings. And furthest out, in all directions, is the vast world ocean where the Midgard Serpent lives.
