Who is it?
The embodiment of the life-force of the Sargrass Plains
There was once a vast reservoir of Woldsblood under the Sargrass Plains. But that was spilled, and the deluge of Woldsblood not only awakened the Sargrass as an immortal power, but entwined the newborn power with the Realm of Shadows. The Sargrass is only beginning to come to terms with its new divinity.
The Sargrass Plains, and the part of the Realm of Shadows that is close by the Southern Continent
