Named for the color of the lush grasses that grow thick and sweet in the warm seasons, this valley is all that remains of a great freshwater lake that dried away long ago. Large prey flock to this place during spring and summer, taking advantage of the easy grazing, meaning better chances for successful hunting for predators of all types. A river winds lazily through the valley, sparkling and clear, with soft, sandy shores here and there. Smaller prey animals make their homes here year around, in burrows and warrens.
