Heimdall is attested as possessing foreknowledge, keen eyesight and hearing, and keeps watch for invaders and the onset of Ragnarök while drinking fine mead in his dwelling Himinbjörg, located where the burning rainbow bridge Bifröst meets the sky.
He possesses the resounding horn Gjallarhorn that will alert all the gods to the coming of Ragnarok. He owns the golden-maned horse Gulltoppr, has gold teeth, and is the son of Nine Mothers.
Heimdall is said to be the originator of Asgardian social classes. Heimdall visited Midgard in human guise and stayed one night in each of three different houses. Each house treated him differently, and he cursed or blessed their children accordingly. The result was the three social classes of the Asgardian world: thralls or slaves, free peasants, and nobles.
Prophesies say that in the last battle, Heimdall's nemesis Loki will steal Heimdall's sword. Though Heimdall is destined to kill Loki in Ragnarok, he is fated to die soon thereafter of his own wounds.
Many of Heimdall's clergy are fighters or rangers in addition to being clerics. Though rare in Asgardian cultures, paladins and monks also may devote themselves to Heimdall.
Temples
Heimdall's temples are generally part of a community's defenses and include at least one watchtower. They feature arrow slits for windows and their doors are easily barred. Patrons of the temple enjoy feasting, drinking, and carousing as much as any Asgardian, but they tend to limit themselves to certain times of the day or night, and are careful to be fit for their duties. Most communities welcome the temples as a way to strengthen their defenses and better protect the local people.
Visitors to Heimdall's temples receive careful examinations by clergy seeking to emulate their god's powers of perception. Those bringing information related to the community's defense find themselves in "war rooms" filled with maps and defensive plans.
The cult of Heimdall appeals to those who find themselves on the edge of their community, facing outward and looking for threats. This attracts fighters of all sorts, as well as nobility and officials who believe in a strong defense. The clergy teaches self-discipline, responsibility, and obedience to authority.
Heimdall is known as the shining god—the whitest of all the gods. He has golden armor and golden teeth. Heimdall is often depicted holding a large horn to his lips and clasping his sword called "Head." Heimdall owns a golden horse named Gulltoppr.
Heimdall is said to be a son of Odin, born from 9 mothers who were all sisters; the theory is that he is the son of the 9 daughters of the sea god, Aegir.
