Along a wooded area overlooking a wide open meadow there is a large stone formation, carved into which there is a chair. The formation is overgrown with vines and other vegetation and looks to have been made a very long time ago. Sitting in the chair looking over the meadow are the remains of a man that has been dead for quite some time. His bones can be harvested for 3 pawns of Corpus vis.
Anyone who sits in the throne suffers a Perdo Corpus effect similar to the spell Clenched Grasp of the Crushed Heart. After they die and their body decomposes in the chair, their bones may also be harvested for 3 pawns of Corpus vis. The remains must be left to sit in the chair for a year before they can be harvested for vis.
The origins of the formation are unknown.
