The
World Tree, Yggdrasil
(an ash tree), is the Universe. It has three roots. Each of the roots reaches
into a different land. The three lands are Niflheim
(home of the dead -- straw deaths only), Jotunheim
(home of the Frost Giants -- Jotuns are
the enemies of the gods), and Asgard (home of the gods). The Aesir are the
gods.["Heim" = home. "Gard" = place (e.g., garden).]
Beneath each of the tree roots is a well. The well of the root of Jotunheim is Jot, or the Well of the Wyrds. It is home to the three Wyrd Sisters. ["Wyrd" = fate, doom] The sisters are also called the Norns. One spins the string of fate, one weaves it, and one cuts it. One faces the past, one the present, and the other the future. The well of Asgard, is Mimir's Well. Mimir is the god who guards the well of knowledge of the future. He won't let anyone drink from it. The well of Niflheim is the spring of Hvergelmir. The only way into Asgard is to go across a bridge called Bifrost (the rainbow). The Aesir don't want Frost Giants in their city. So there is a gate at the end of the bridge made of Ymir's eyebrows. Somewhere near the middle of the tree is the land where the humans live. This land is called Midgard (Middle Earth). Alfheim is the home of the elves. Svartalfheim is the home of the dark elves ["svart" as in "swarthy"]. They are thought to live underground.
In the branches and eating the leaves are various deer. Perched up on a branch is an eagle which can look out over the universe and see everything going on. On the eagle's forehead sits a hawk who reports news to Odin. Wrapped around the roots is a serpent called Nidhug who gnaws at the roots. If he gnaws through and the tree topples, everything will collapse and be destroyed. Running up and down Yggdrasil is a squirrel called Ratatosk, a mischief maker who talks to the eagle and talks to him through the snake, lying to both and telling each what terrible things the other says about him. His name means "rat tooth." The deer are not malevolent, but they could hurt the tree. In Scandinavia, certain animals are looked on with and without favor. The bear is respected. Snakes are despised. Birds of prey are especially popular. Wolves have a checkered career -- mostly evil. Squirrels are looked on with humor. The characters are almost always male.
