Gyundi nuts have a hard, fibrous outer shell, which is only edible when cooked and does not taste very good. In the center of each nut is a much better tasting core that is rich in fat and has a high calorie content.
Gyundi nuts are native to the Death Sands.
Some of the trees that sprout the nuts had been planted at Mitca's Refuge, an oasis not too far outside of the walls of Parthos. The oasis was burned to prevent Orcs from using it when they laid siege to the city, so none of the trees remain. However, wild gyundi nut trees can still be found in various areas around the desert landscape of the Death Sands.
