Midgard

In Norse mythology, Midgard is the Earth. It was created when the supreme god, Odin and his two brothers slayed a giant. The roots of the tree reach into the underworld and up into the land of the giants. Midgard is surrounded by the ocean where a giant snake lives.

Asgard, the home of the gods, was joined to the Earth by a bridge called Bifrost, symbolized by a rainbow. Odin, the supreme Norse god, is able to look down over all that he rules.
