Not to be confused with the Grand Master of the Deathwing
The twin Lords of Phlegethos, Belial and Fierna are a father and daughter pair who run the Fourth layer jointly. After a failed coup that Belial was a part of, he offered to share power with his daughter Fierna to appease Asmodeus. He accepted and so Fierna became the co-ruler of Phlegethos. Both of them look almost completely human, aside from their horns and clawed fingers. Both are rather attractive with sadistic personalities: they revel in killing and bloodshed. But they are no fools and will retreat when in trouble. Belial is very much a traditional devil: he's cautious, scheming and making plans to overthrow his fellow devils. He personally trains his daughter in how to be a good devil, including personally taking a hand in teaching her about "love and pain", which is exactly what it sounds like. Bleh.
