Heimdallr was the patron saint of Bifr ö st, the rainbow bridge in Nordic mythology. He scouted for invaders and waited for the gods to appear at dusk in his residence, Himinbj ö rg, where Bifr st could lead directly to Asgard. Heimdar is the son of Odin, the god king of the Asa clan, and the nine goddesses. Legend has it that he has golden teeth and pure white skin, hence he is known as the "White Asa God". He also has sharp senses, with his eyes able to see six paths. He can see three hundred miles away day and night, and his ears can hear all directions. When he falls on the ground, he can hear the hissing sound of grass growth and the sound of wool growth. It is said that his strong hearing was obtained by sacrificing one ear.
Heimdal has a golden haired horse called Gulltoppr, and a sword with a face on it ǫ Fu ð And a resounding horn Gjallarhorn, when the gods reach dusk, Hemudal will sound the horn to remind them. Heimdar and Loki were enemies in the twilight of the gods, and they were prophesied to kill each other during the twilight of the gods. The reason for their mutual confrontation may be related to Freya's Bridgeman, as Loki once stole the necklace, and Hemdal turned into a seal and fought with Loki to retrieve it.
It is said that he was the founder of the human social class, once renamed R í g, described as "ancient and wise, extraordinary and powerful", and known as the "father of mortals". He also has other aliases, such as Hallinski ð i. Gullintanni, Vindl é r, or Vindhl é r. Due to the existence of problems and mysteries, scholars have proposed theories about Hemudal, including his possible incarnation of the world tree Yggdrasil or related existence.

Heimdal is the guardian of Asgard, guarding the Rainbow Bridge Bifr ö st that leads to Asgard. This bridge is also known as Á sbr ú, or the "Bridge of Asa". In order to shoulder such a task, the gods gave him the best eyes, even in the dark, he could see far away. Give him very sensitive ears, even the sound of grass and wool growing can be heard, and he won't be tired without rest day and night.
He also has a warning horn called 'Gjarlarhorn'. Heimdal usually guards near Rainbow Bridge, monitoring with his piercing eyes and ears to prevent giants from sneaking into the realm of the divine realm. But he also had his own palace, Himinbjorg (meaning "Palace of Heavenly Guards"). In addition, his horse is called "Gultopp" (meaning "Golden Summit").
The god he dislikes the most is Loki, so he is also known as the 'enemy of Loki'. In the twilight of the gods, Hemdal will engage in a duel with Loki and perish together. At the same time, he was also the last god to fall.
The most unique feature of Heimdal is its golden teeth, hence its nickname Gullintani. In addition, he is also known as the "White God" or "White Asa", some say because his skin is fair. Some people also believe that Hemudal is actually the embodiment of a pointed ram.

Heimdar is a god belonging to the Asa tribe, whose father is Odin, as confirmed in the Icelandic poet Snory Sturusson's "Ada".
The mother is nine sisters, who gave birth to Hemudar for Odin. The myth says: "I am the child of nine mothers, and also the son of nine sisters.". Scholars speculate that Heimdal's nine mothers may have identical roles with the nine daughters of Egir and R á n, who are personified by the waves. However, the names of the nine daughters and nine mothers do not match in different documents, including even Yanshasa, who is a lover of Thor.

Legend has it that the three classes of humanity were created by Hemudal. He once changed his name to Rigg and stayed in three families.
The first family lived with an elderly couple named Ai (great grandfather) and Edda (great grandmother). They lived a hardworking and hardworking life, and after the departure of Hemdal, the family gave birth to a child named 'Thrall', also known as' slave '. Sal later married an ugly girl named Thyr (a female slave), who gave birth to twelve sons and nine daughters, from whom all members of the 'slave' class were passed down.
The second family is relatively wealthy, with the male owner named Afi (grandfather) and the female owner named Amma (grandmother). They are good at domesticating livestock and building houses and fields. After Rigg left, the family gave birth to a child named "Karl", also known as "farmer". After marrying his wife Snor (daughter-in-law), he gave birth to twelve sons and ten daughters, and was the ancestor of the "free people" class of farmers and herders.
The third family is very wealthy, with the male owner named Fadir (father) and the female owner named Modir (mother). They have exquisite decorations and the wearer's temperament is elegant. After Rigg left, the family gave birth to a child named "Jarl", also known as "the prince". After Yael grew up, Hemudar appeared before him again, allowing him to inherit a large amount of gold and silver, and teaching him the Runic script. So Yal gained a lot of land and wealth in the war, and later married the beautiful daughter of Hersir (lord), Erna (lively), giving birth to eleven sons, who were the ancestors of the royal families and nobles of the Scandinavian states.
These three classes of people, regardless of their status, consider Righ (Hemdal) as the ancestor and guardian god of humanity.
