Tall and handsome and known for his purity of heart and mind, Heimdal is the ever-vigilant guardian of the gods. In many stories he is the son of Odin and nine mothers who are believed to be the wave maidens.
Heimdal is blessed with extraordinary sight and hearing. He can see for 100 leagues and can hear the grass growing. His horn, Gjallarhorn, can be heard throughout heaven, earth and the lower world to summon the gods when their enemies, the giants, draw near at the Ragnarok, the end of the world of gods and men. When that time comes, Heimdal and his enemy Loki, god of mischief, will slay each other.
