The Cold Lord

Mephistopheles, the Lord of No Mercy, has given the Warlock its power. Now, the Cold determination of the Lord of the 8th Circle of Hell burns within the mortal flesh of whoever has taken the power of Mephistopheles for themself. 

Mephistopheles (pronounced: /mɛfɪzˈtɑːfɛliz/ me-fiz-TAF-e-leez[2]), also known as the Lord of No Mercy and the Cold Lord, is the lord of Cania, the eighth level of the Nine Hells. He was the main opponent of Baalzebul during the Reckoning of Hell, and still holds a claim to his own layer. He seeks to take Baalzebul's layer away from him, that he may gain enough power to one day challenge Asmodeus for rulership of all the Nine Hells.

Mephistopheles is something of a walking contradiction. Unstable and thoroughly wicked, he presents multiple faces to those he meets. On the one hand, he can be charming, erudite, and civil. But beneath the veneer of respectability is a vicious temper and unchecked ambition. He is patient and cunning, yet when alone, he flies into a fury, screaming and shrieking, tearing at his skin and destroying everything around him in a thunderous explosion of hellfire and devastating magic.

He has one goal, one reason for existence: He covets Asmodeus’s throne. It is, in his mind, his destiny to rule the Nine Hells. Mephistopheles still poses a grave threat. He commands legions of ice devils as well as the pit fiends, barbazu, and cornugons that have flocked to his banner. In addition, it falls to him to protect the only gate into Nessus, so he nominally commands the army whose sole duty it is to safeguard Asmodeus’s realm. To make matters worse, he has mastered the essence of Hell, channeling it into foul destructive energy called Hellfire.

His temples are strange places, hidden and out of the way. Decorated with fire pits, they are unbearably hot and the pits are rigged so that they flare up during ceremonies at the most dramatic moments. The cultists meet to perform sacrifices, binding their living victim on a blackened altar and immolating him alive. His screams add the chorus to their silent prayers.
