Belial

In name, Fierna rules Phlegethos, commanding the fiery layer from her palace of rock and magma. In truth, her father, Belial, is the power behind the throne. Sequestered away in the central Hall of One Thousand Sighs and Screams, he advises his daughter in the arts of love and pain, taking a personal hand in ensuring she learns all there is to know. Up until now, the situation suited Fierna just fine. But thanks to her flowering relationship with Glasya, she has become more interested in taking Phlegethos in more than just name. No longer is she content to sit idly by and let her father make the decisions. She has even cultivated a few cults on the Prime Material Plane. Fierna’s newfound ambition concerns Belial, but he has other worries. He had been assembling armies to invade the fifth and sixth layers, confident his forces could overcome those of Levistus and the Hag Countess. But Glasya’s surprising coup stalled his plans, and now he can’t move at all, since doing do so would invoke the full force of Asmodeus’s ire. For now, Belial is content to watch and see what develops with this new player in Hell’s vicious political game. Belial and Fierna surround themselves with a variety of devils, including several legions of barbazu and hamatulas, but they are most famed for their kennels. These breeding pits produce powerful hellish beasts that rival even the Nessian warhounds Asmodeus uses to protect his halls.

Apperence
These two humanlike figures are tall, dark, and sensual. They each have a pair of small horns jutting from their brows. Their red eyes smolder with the promise of physical pleasure, and the fine clothing that clings to their bodies completes the debauched image.
