The Stockwood Scrolls
The abishai are a type of devil of the Nine Hells, often acting as cruel torturers and wardens. They owe their allegiance to Tiamat. In order of ascending power, the five colours of abishai are white, black, green, blue, and red.
They resemble living gothic gargoyles with scaly skin, with the wings of a bat, and a whipping, prehensile tail that ends in a stinger.
