‘They are tall, gaunt. Their skin is white as alabaster, and their limbs do not move as do those of humans. From their elbows, they can bend their lower arms in all directions. It is said their bodies are hinged, as if they had two sets of hips, one stacked atop the other. And they can stand like us, or with legs like those of a horse. No weapon can reach them, and a single touch from their long fingers can shatter all the bones in a warrior’s body. Sorcerous attacks drain down from them like water.’
