The Storm Guard
Tarneus, the Plague Bringer is the god of disease. He brought the plague upon Meyan and wiped out 1/3 of the world’s population with pestilence.
Tarneus corrupted the heart of Priest Maxwell of Nestraden and used his sickened body as the vessel of the Plague Lord whom allowed Tarneus to find the cradle of life and take full form on the Material Plane.
Tarneus was defeated by the chosen of the gods who made an ultimate sacrifice to save Meyan.
