Curse of the Night Blood Orcs

From publisher blurb:

In the city of Davenshire the populace knows they had better be indoors before dusk. This curfew is not enforced by the city militia, but instead by the phantom-like orc raiders of the Night Blood Clan, who appear as silent as a shadow and as deadly as nightshade. The orcs have become a part of life in the city, but recently they have stepped up their raids and now they've gone too far, kidnapping a citizen! The city of Davenshire has put out the call for help in ridding themselves of this threat. Will your heroes rise to the challenge and unravel the mystery of the Curse of the Night Blood Orcs?

This module is intended for 7th level PCs
