In Norse mythology, Yggdrasil is described as the central cosmic tree that connects the nine worlds. As the “World Tree”, it is perhaps one of the most mystical concepts in Norse beliefs. Yggdrasil plays an important symbolic role as it binds these different realms together through its extensive root system. At the heart of Norse cosmology lies this great tree and the secrets of the nine worlds hidden within its branches and roots. Let us explore the mysteries of each realm and their connection to Yggdrasil.
Múspellsheim
Múspellsheim is described as an intensely hot realm that is constantly ablaze. It is located in the southern part of the cosmos and is ruled over by the fire giant Surt. As one of the first two primordial lands along with Niflheim, Múspellsheim represents the forces of fire. It is the realm from which the fire that will consume the worlds at Ragnarok will come from. At the end of days, Surt will destroy the rainbow bridge Bifrost with flames before battling the god Thor. Múspellsheim symbolizes destructive elemental forces that bring about great change.
Niflheim
Vanaheim
Asgard
Helheim
Further down Yggdrasil’s roots lies the grim realm of Helheim, the land of the dishonorable dead. It is ruled over by the death goddess Hel, who Odin banished there. Helheim is a dark realm full of mist and fog where those who die from illness or old age are sent. Here lies a hall called Éljúðnir guarded by the monstrous hound Garm. Some describe Helheim as existing within the borders of Niflheim. It symbolizes the fate of weak and defenseless souls according to ancient Norse beliefs.
Svartálfaheimr
Svartálfaheim lies beneath one of Yggdrasil’s roots and is home to the dark elves known as svartálfar. Very little is known about this realm aside from it being the domain of these mysterious subterranean elves. The svartálfar were thought to dwell in caverns and mountains, guarding hidden treasures. They were often associated with magic, craftsmanship and ill fortune. Svartálfaheim seems to represent the unknown shadows of the underground world.
Nidavellir
Deep below the surface amidst the roots of Yggdrasil lies the realm of Nidavellir. It is here that the dwarves known as the durin folk dwell and practice their smithing arts. The dwarves are masters of crafting fine armor, weapons and gems. It was in Nidavellir that the gods commissioned magical items from the dwarves like Thor’s hammer Mjolnir. The dwarves delved deep shafts and halls within the earth. Nidavellir symbolizes craftsmanship, hard work and treasures buried beneath the soil.
Álfheim
Jotunheim
Finally at the center of the tree lies the realm of Midgard, the world of mortal men. Midgard was surrounded on all sides by a great sea and was prone to invasion by giants from Jotunheim. It was in Midgard that the gods fashioned the first humans Ask and Embla from driftwood and breathed life into them. Midgard symbolizes humanity, civilization, community and daily existence under divine rule and protection. Yggdrasil’s branches reached above to embrace Midgard while its roots delved deep to connect all other worlds.
Such were the Nine Worlds bound together by the great axis mundi of Yggdrasil according to Norse mythology. The tree acted as a mystical scaffolding holding aloft the diverse realms and beings that comprised their cosmology. It linked the primordial forces of fire and ice, homes of the gods and other supernatural races, and the world of mortal men under divine purview. Yggdrasil’s roots gathered the waters from every realm while its branches provided passage between the heavens and the Underworld. At the heart of Norse pagan faith was this profound symbol of the entire cosmos, now only a mysterious memory from the distant past.
