Asgard

Much like Mount Olympus is home to the Greek gods, Asgard, or Ásgarðr in Old Norse, is home to the Aesir. The Norse gods (Aesir) and goddesses (Asynjur) live in this prosperous world of glory, order, and law. This civilized aspect is physically represented by a great wall separating Asgard from the realms around, or rather, below it. In fact, "Asgard" means "Enclosure of the Aesir."

The fortress is ruled over by Odin and his wife, Frigg. In it can be found many halls, such as Válaskjálf - Odin’s hall with a silver roof from which he can see all the nine realms at once. It is commonly known as the realm containing Valhalla, Odin’s feast hall, where those who die valiantly in battle go to await Ragnarok. These warriors, known as einherjar, only make up half of the worthy dead, with the rest going to another such hall - Fólkvangr - in Vanaheim. Another key feature of Asgard is its Bifrost, or Rainbow Bridge. This magical structure connects the world of the gods with that of humans.
