"Ratatoskr is a squirrel who runs up and down the world tree Yggdrasil to carry messages between the unnamed eagle, perched atop Yggdrasil, and the wyrm Níðhöggr, who dwells beneath one of the three roots of the tree." What this introductory statement from Wikipedia doesn't say is that the nature of most of those messages are insults.  Sadly, Ratatosker has no place in our modern world view; that position has been usurped by bloggers.
