Heimdall ("The White God") is the god of light, and the son of nine mothers (daughters of Geirrendour the Giant). He was born at the end of the world and raised by the force of the earth, seawater and the blood of a boar. Because of his shining, golden teeth he is also called Gullintani ("gold tooth"). His hall is Himinbjorg ("The Cliffs of Heaven") and his horse is Gulltop.

He is the watchman of the gods and guards Bifrost, the only entrance to Asgard, the realm of the gods. Heimdall possesses the horn Gjallarhorn that he lightly blows whenever a god enters or leaves Asgard. It is Heimdall's duty to prevent the giants from forcing their way into Asgard. He requires less sleep then a bird, and sees by night as well as by day a hundred miles around him. His hearing is so keen that he can hear the grass growing on Midgard and the wool growing on sheep. But when the frost-giants come across the bridge to battle the gods at Ragnarok, Heimdall will give a great blast on his horn, that will be heard across all the world. At the final battle of Ragnarok he will kill his age-old enemy, the evil god Loki, but will die himself from the wounds inflicted by him.

As the god Rig ("ruler"), Heimdall created the three races of mankind: the thralls, the karls, and the jarls.
