Probably the most agriculturally suited area in all of Kooluk, the Xasta Grassland resembled the Terana Plains in many ways due to their similar location, with the Xasta Grasslands lying just to the west of the Terana Plains. However, unlike Terana the area is not as dry making it more suitable for crops.
Like Terana, however, large rocks and boulders dot this area too, putting a limit on how much could have possibly been accomplished by farming this grassland.
As the Xasta Grassland runs west, it morphs into the Terana Plains. The mysterious and hostile Ostrich People also inhabit the plains.
