In Norse cosmology, the universe is a living network formed by nine interconnected worlds. None of them exists in isolation: all depend on the great ash tree Yggdrasil, the cosmic axis that sustains creation. Yggdrasil, el eje cósmico que sostiene la creación.
Although the Eddas do not offer a definitive map, a widely accepted interpretation divides these worlds into three levels:
- Lower Level: the roots of the cosmos.
- Middle Level: trunk and branches, where active life unfolds.
- Upper Level: the celestial crown and the luminous worlds.
