Gravesand is the pulverized bone-dust of fallen Gumm-Gumms. It helps Changelings embrace their trollish nature, but in humans, it hones their feral instincts, even though it is not meant for humans. Gravesand changes the human's nature. Some of the changes are permanent. Grave Sand is purple dust, that the person can inhale or drink. For humans it turns their eyes to yellow, their irises are red and the pupil is yellow.
