When the Caliph-Emperor of the Dunes hear about his son's heart attack at the northern front, his rage is unstoppable. For his son was only nineteen years old, and a trained athlete. Grief stricken as only a parent bereft of their child can be, the Emperor finally rouses the Empire into action.
So, when reinforcements finally arrive to the beleaguered veterans at the front, they are accompanied by the the Imperial Necromancers in their gold laced red silken robes, as well as the three old triplet hags of Devananon, seers and prophets who use narcotics to enhance their trance visions.
As the Prince's corpse is carted to the Spires of Devananon, where the necromancers and the triplets will work their magic, the PCs will have to conjure a plan of their own. For they are to blame for the Prince's death.
This plot is set five months after the happenings of "A Dark Moon over Sagranz", but could be adapted by any GM to fit his setting and need.
