Blurb from the Lulu page:
Through the aeons, a golden box appears from time to time to tempt the greediest of thieves and treasure seekers. Sages say the origin of that odd box is lost to the gulfs of time, but in the Scrolls of Skrel there is one account...
When Man was new and Angels and Demons walked the world, a king arose, uniting the tribes, and waging war on Demonkind. This was Zoforon. Of such valiance was his crusade that the Angelic Order joined his cause. Thus began the age of the Holy Wars. Years of conflict became decades, and the decades beget centuries. The endless struggle ground Zoforon down, until finally he descended into madness. The Archangel, grieved by Zoforon's fall, but fearful of the Demon magic he now possessed, fashioned a golden box in which Zoforon might be bound and forever locked away. But Zoforon was no fool. Facing hostile forces of Angels and Demons alike, he devised a trap to thwart them all!
