Asgard

Asgard (“the farm of the gods”) is the home of the Aesir and one of the cosmological realms found in Norse mythology. Allegorically, Asgard represents the concepts of “home,” “civilization,” and “what we know and are familiar with.” It stands in contrast to Jötunheim, which represents the “the terrifying unknown.”

After Odin and the gods created Midgard, the physical realm in which we live, he and the gods created a separate, otherworldly realm for themselves called Asgard. This realm is connected to Midgard via the rainbow bridge called Bifrost, which we see appear in the sky after one of Thor’s storms. Thor drives his goats and chariot over the rainbow and back to Asgard after he visits Midgard to fight off giants. The giants can’t follow him because the red color burns hot beneath their feet.

Heimdall watches over the bridge and Asgard’s gates and warns of any oncoming danger. It’s where many of the gods have their halls, including Valhalla.
