" There are four places where the spirits still wander . . .
the snow-covered Dark of Night, the forgotten paradise of Sobri Elan,
the Glass Pillars of Dumon, and the human mind,
that eternally mysterious realm where ghosts shall forever walk.
—An Exploration of Ancient and Modern Myths, by Mordove Senia "
