Destiny Times Three by Fritz Leiber

The ash Yggdrasil great evil suffers, Far more than men do know; The hart bites its top, its trunk is rotting, And Nidhogg gnaws beneath. _Elder Edda._

In ghostly, shivering streamers of green and blue, like northern lights, the closing hues of the fourth Hoderson symchromy, called "the Yggdrasil," shuddered down toward visual silence. Once more the ancient myth, antedating even the Dawn Civilization, had been told -- of the tree of life with its roots in heaven and hell and the land of the frost giants, and serpents gnawing at those roots and the gods fighting to preserve it. Transmuted into significant color by Hoderson's genius, interpreted by the world's greatest color instrumentalists, the primeval legend of cosmic dread and rottenness and mystery, of wheels within cosmic wheels, had once more enthralled its beholders.
