From publisher blurb:
What do demon-worshiping ghouls, vile sorcerers and werehyenas have in common? They are all found in A Touch of Evil Volume 3: Gnolls.
Inside this 70 page PDF you'll find two fully detailed gnoll tribes; the insidious Bloodfangs and the shape-shifting Moonwolves. Immerse yourself in the machinations of characters such as Ejark Demon-Talker, a cleric of the demon god Yathoggni who is obsessed with immortality and the creation of ghouls, or Chief Gathrote, a werehyena who leads the Moonwolf tribe in the frigid northlands.
Each of the 10 NPCs has 3 levels advancement, suggestions for using them in your campaign and information for using each one as a Player Character! A ghoul template, rules for playing younger gnolls and statistics for lesser members of the tribes are also included.
