These devotees of Kali were never human, unlike many of the transformed priestesses. Instead they are an ancient species of half snakes with deep knowledge and magical ability. They were, however, more corrupted in some ways than their mistress was when the curse of the Templar gold effected them. Normally they are friendly and helpful - even opening hidden doors and showing shortcuts. However, with a flip of Kali's coin, their eyes turn black, their jaws unhinge with a hideous hiss, and the soft pink skin turns a dark blue as their only motivation becomes to swallow you whole. They will struggle against this and even warn you as this corruption isn't their essential nature. In this in between state their eyes remain yellow, but half of their bodies is pink, and the other blue. Part of the danger is they have lead you into hidden places and shortcuts that may suddenly be harder to escape....
