Diaboli originally crossed into the world of Mystara from the Demi-plane of Nightmares. Creatures from this realm manifest as human’s fears. However, despite the Diaboli’s appearance, they are generally well-mannered friendly folk, that have little interesting tormenting the planar species. Nevertheless, Diaboli are usually met with revulsion and scorn. 
These creatures have a navy blue to lavender skin coloring, and long shaggy white hair, with males normally wearing beards. Their legs end in cloven hooves, and a long serpentine tail, capped with a scorpion’s barb writhes unconsciously behind them. Despite the commonality of the Diaboli’s appearance, there exists several subspecies, each denoted by the amount of hair, which to humans is a trivial, if not negligible matter.

Combat
Outsider: Outsiders cannot be raised or resurrected, although a wish or miracle can restore it to life. Outsiders cannot be targeted by spells that affect humanoids. 
Poison (Ex): The Diaboli’s poison has an immediate onset time, activated by injury, with a DC 14, and inflicts 1d6 temporary Dexterity damage on the first round/ and paralysis on the second round that lasts for 1d6 rounds. 
Diaboli Characters: The Diaboli’s favored class is the Bard.
