Mephistopheles

The Cold Lord
The Lord of the Eighth plane of Hell, the frozen Cania. Mephistopheles is Asmodeus's greatest enemy and most powerful vassal. He keeps no secret to his true goals, overthrowing the Lord of the Hells and becoming the god of devils. Asmodeus will not destroy him outright, he sees too much potential in the Cold Lord to be rid of him.

The plane of Cania that Mephistopheles is dangerous in a unique way that even the ninth layer can not compete. It is filled with ruins of past ages, hidden knowledge from the time of He Who Was. The vast icy tundra has more than just devils lurking in it, and only Mephistopheles knows all the dark places.

The Lord of the Ninth and Eight have a rivalry unmatched by any beings in all the planes. A rare brew of respect, admiration, hate and ambition force both of them to plot against each other, but work together lest they be destroyed and someone truly unworthy take the mantle of Lord of Hell.
