Overview
Ratatoskr is a small but infamous creature of Norse mythology. A squirrel who lives on the great World Tree, Yggdrasil, he spends his days racing up and down the cosmic trunk delivering messages — most often insults — between the eagle who sits atop the tree and the dragon Níðhöggr who gnaws at its roots.
Although Ratatoskr may appear harmless or even playful, his role emphasizes the tension and hostility that exists across the nine realms. Rather than bringing peace, he thrives on escalating conflict, acting as a mischievous agent of chaos.
Some later interpretations view him as a symbol of gossip, rumor, and the disruptive power of words — a reminder that not all threats come from strength or sorcery. Some simply come from a fast-running squirrel with a talent for trouble.
Key Roles
Messenger of Yggdrasil
Ratatoskr carries messages between the eagle perched atop Yggdrasil and the dragon Níðhöggr below. These messages are rarely friendly, and he seems to delight in worsening their quarrel.
Instigator of Conflict
Rather than faithfully relaying information, Ratatoskr often twists messages or invents insults to aggravate both sides. His meddling adds instability to the cosmic order.
Symbol of Gossip & Chaos
Ratatoskr is often interpreted as a metaphor for the damage caused by rumor, miscommunication, and the spread of lies. His role demonstrates how even small forces can influence great struggles.
