In Norse mythology, various animals inhabit the world tree Yggdrasil, each symbolizing different cosmic forces. At its summit sits an eagle, watching over the world, while between its eyes is the hawk Vedrfölnir, who shapes the weather. In contrast, the dragon Níðhöggr gnaws at the roots, representing destruction and envy. The squirrel Ratatoskr constantly scurries back and forth along the trunk, relaying insults between the eagle and the dragon, symbolizing eternal conflict and communication. Furthermore, the four stags Dàin, Dwalin, Dunneir, and Durathror devour the tree's buds, representing the constant cycle of decay and renewal in nature.
