Real citation: "The Imps hold the Pixie forest to the east of the Dwarven kingdom. They are humanoid, in that they have two arms, two legs, and a head, but otherwise they more or less resemble vague sillouhettes. Their skin is purple or pink and their eyes glow with magic. Their feet, hands, and the tentaclesque thing on the back of their head is sepia brown."
