Tree of Existence, as conceived of by the Norse, and reflecting the Norse idea of the universe, "has its roots deep down in the kingdoms of Hela, or Death; its trunk reaches up heaven-high, and spreads its boughs over the whole universe. At the foot of it, in the Death-Kingdom, sit the Three Nornas ( q. v .) watering its roots from the sacred Well."
