From the introduction: The PCs have been on the path of The Cult of the Mega-Maiden. The Cult seeks to bring the Demon Seed of Deth to the Iron Ziggurat of the Mega-Maiden. There they hope to perform the Ultimate Ritual and fulfill the Prophecy. This will break open the Demon Seed and bring the Wrathchild into the world with the Mega-Maiden acting as surrogate mother. We begin in medias res, in the middle of the plot. This gives Judges various options to drop this into an existing campaign with some minor set up, make this the culmination of previous adventures, or just run this as a speedy one-shot.
