Another piece of Ancient Norse Mythology – Ratatoskr is another ''Resident'' of The ''Great Tree of Life'' – Yggdrasil. As with other ''Entities'' that live on The Tree, Ratatoskr is a ''Messenger''. He takes messages from The ''Great Creator'' (symbolized as an Eagle) to the mischievous Niohoggr. Medieval Art portrayed Ratatoskr as a large''Squirrel'' with a huge tusk on it's head. This is used to bore into The Tree so He can hide from Niohoggr's wrath.
