Excerpt from Book:
The scene is laid in a shadowy and mystic place known to the dwellers there as The Darker Realm. It has been built and burrowed from time immemorial far down underneath some great, beautiful, sunny, human metro polis, called The World Above, but of this light-crowned city those who inhabit the subterranean retreats of The Darker Realm know but little, of its happy days and doings they can but dream.
