In the Norse eddas, Yggdrasil, the world tree, was an Ash. The spear of Odin was made from the branch of this tree, which is also known by the Celtic name Nion, pronounced knee-un. This is one of three trees sacred to the Druids (Ash, Oak and Thorn), and this is a good month to do magic that focuses on the inner self. Associated with ocean rituals, magical potency, prophetic dreams and spiritual journeys, the Ash can be used for making magical (and mundane) tools — these are said to be more productive than tools made from other wood. If you place Ash berries in a cradle, it protects the child from being taken away as a changeling by mischevious Fae.
