Asgard (Old Norse: "Ásgarðr" - “Enclosure of the Æsir; Court of the Ás”) is one of the Nine Realms in Norse mythology, home to the tribe of deities known as the Æsir. Asgard lies at the top of Yggdrasill’s highest branches, and the only thing connecting Asgard to Midgard is the mystical rainbow bridge Bifröst.
