Toski, Bearer of Secrets.jpg
Race Squirrel
Birthplace Cosmos, Kaldheim
Lifetime Unknown

Toski is a small Cosmos monster from Kaldheim and the messenger of the gods.[1][2]


Toski is a mischievous squirrel who serves Esika, the god of the World Tree. Though he is tiny (especially compared with some of the other Cosmos monsters), he scampers with unbelievable speed along the World Tree to bring news and carry messages between the Ten Realms. His small size allows him to observe events in all the realms and prize out secrets which he then carries back to Esika. Toski doesn't speak. He and Esika communicate by a mysterious form of telepathy, ensuring that the secrets Toski brings to the god remain exactly that.[3]


  • Inspired by Ratatoskr a squirrel that in ancient Nordic mythology runs by the Tree of the World Yggdrasil, carrying insult messages exchanged by an eagle (who lives on top of the tree) and Níðhöggr (who lives between the roots).
  • Toski does have one of his forelegs replaced by a kind of "prosthesis", which may be a reference to the one-hand god Týr.
