Cabal of Shadows Faction Adventure
From the introduction:
The sahuagin of clan Regvagu have prowled the seas of Shargon's Teeth for centuries. Dedicated to the Devourer and his ways, their rule is dictated by a circle of priests who in turn take their direction from an unusual holy text they believe to have been sent to them by their deity.
