Gravesand is the pulverized bone-dust of fallen Gumm-Gumm s. It is a purple dust, that the person can inhale or drink. It helps Changelings embrace their trollish nature, but in humans, it hones their feral instincts, making them as aggressive and violent as a Troll. Gravesand changes the human's nature, turns their eyes to yellow, their irises are red. Changes from the Gravesand become permanent unless the victim achieves an emotional connection with their human feelings.
