"Yggdrasil is a massive sacred tree, around which all life exists. Many creatures live inside it, including four deer: Dáinn “The Dead One”, Dvalinn “The Unconscious One”, Duneyrr “Thundering in the Ear” and Duraþrór “Thriving Slumber”. They are said to crane their necks upwards to browse the branches, while morning dew gathers in their antlers to form rivers. Interpretations are debated, scholars theorize they could represent the four elements, the four seasons, or the phases of the moon. A similar function is served by a singular deer, Eikþyrnir, who resides atop Valhalla."
