In the fourth installment, we delve deeper into Asmodeus' insidious influence on the magic of the Prime Material Plane, detailing his perversion of spells from Hallucinatory Terrain to Maze.
Gleaning from prophecies and powerful divinations that the heroes might challenge his schemes, he finds himself intrigued by his playthings and their feeble struggles.
To satisfy this curiosity, Asmodeus decides to send out a spy. He chooses Sarnathra, a Cambion known for her shrewdness and discretion, to subtly keep watch over the heroes. Sarnathra's mission is to observe from the shadows, gathering intelligence for Asmodeus without drawing attention to herself or her objectives.
But the heroes will have to deal with more than the beautiful Cambion, finding their sleep plagued by unsettling and persistent nightmares of chains and dark rivers . . .
