Sacred to Evil is just a matter of Size
In the matter of the acorn that Vainamoinen wanted to sprout and become the Sacred Oak, his impatience was rewarded when a giant kindled the magic fire and the acorn began to grow. And grow. Until the sun and moon were blotted out and the canopy of the Great Oak filled the vault of the sky. The people, plants and animals suffered in the perpetual twilight, and called out for rescue. Vainamoinen could only sing his magic to call for help.
