Dama-Fruit is a magical fruit native only to the Valley of Voe.
It grows on a low plant with broad, spreading leaves. The fruit itself resembles a peach and is daintily colored and appetizingly fragrant. It is considered by the people of Voe to be the most delicious thing that grows.
Eating this rare fruit renders one invisible, whether person or animal. When an invisible creature is killed, the charm of the dama-fruit ceases to be active and the creature becomes visible again. (Dorothy and the Wizard in Oz)
