From publisher blurb:
The Return of the Witch-King Begins!
King Drudge cannot allow any distraction in his bid to conquer the Empire, especially one created by another claimant to the Alabaster Throne. Horus, heir to the Empire, poses such a threat. After brutal fighting, the orcs have crossed over into Tear and ransacked the countryside. Doom falls across this land and the characters find themselves beset on all sides by danger. The characters must come together and learn to work with one another. Otherwise, they become just more grist for the war mill.
Falling Tears launches the long-awaited Return of the Witch-King campaign. This series of eleven adventures brings back the greatest foe the mortal world has ever known: Ashrakal, the Witch-King. An enemy of immortals, gods, faeries, fiends, and others who would enslave mortals to extend their own existence, this foe will stop at nothing to throw open the Underworld’s gates, even if it means breaking the world. In this adventure, the characters seek escape from the war consuming their homeland. Falling Tears plays best with a group of three to five starting characters.
