From publisher blurb:
Vathak: A Stricken World
Welcome to the world of Shadows over Vathak, a realm of dwindling hope and rising despair. As players, your characters fight to survive in a land threatened with destruction by the rise of the ancient and evil Old Ones and their spawn. Your characters may represent points of light in the darkness or give in to wicked temptations. Most will fall somewhere in between — survivors struggling to eke out another day. Though the followers of the One True God speak of divine providence while battling the Old Ones, the sins of the Church often rival those of their enemies. In the world of Vathak, your character’s perceptions of heroes and villains is a thin line drawn by their own personal morality and, of course, determined by the victor.
In this, our Explorer’s Guide to Vathak, we condense down the expansive country of Vathak and game setting of Shadows over Vathak into a short but concise text to introduce the uninitiated and preview all that will be available in future releases.
