Fierna is an archdevil of the Hells and the ruler of the Fourth Layer of the Hells, known as Phlegethos. She is among the most personally powerful beings in the Hells, and is the daughter of Belial. For a significant period of time, she ruled Phlegethos jointly with Belial, after Belial was implicated in an infernal uprising against Asmodeus, but that changed when Belial was once again able to earn Asmodeus' favor and assert ownership of Stygia.
Physical Appearance
As an archdevil, she is able to assume any number of guises, but her most commonly-assumed guise is that of a tall, fair-skinned humanoid woman with long straight auburn hair and horns that protrude forward from the top of her head. She also has small crimson wings high on her back and a slender tail. She has a curvaceous body and rarely wears clothing of any sort aside from a few piercings.
Personality
Fierna presents herself as incredibly easy-going and almost lazy. She is the lady of lust and all things pleasurable in the Hells, and she likes to focus her attentions on that as much as possible. But she is also incredibly crafty and has a very high emotional intelligence. She is a mistress of manipulation and enjoys giving people "what they want" in ways that they don't even realize the costs. She used to take the greatest pleasure in tempting Paladins and devoted followers of the gods into breaking their oaths, but since the changes to the Pact Primeval she has had significantly fewer opportunities to do so.
When her ire is raised, it is a fury like no other. She holds grudges deeply and without remorse, and if she is scorned, that is the quickest way to earn her ill will. At the same time, those who have been in her good graces for a while can attest to her almost doting demeanor, and her willingness to allow certain appreciative refusals to lie. She is one of only a few devils to have given birth herself, although few of those beings, be they Cambions, tieflings, or others have been explicitly identified. One such of her spawn is the (now) archdevil, Pharastra, a woman who devised a plan to raise a mortal child in the Hells in order to see what it might have the capacity to become. (See Sabbatical and Philani for more details of this.)
Fierna enjoys acting as a doting, if absolutely not to be disobeyed, parental figure to the beings in her line, and she has also been known to gladly welcome any tiefling born of her own touches on the realms into her service with some degree of preferential treatment.
History
Fierna herself has not yet featured in any Quelmar campaigns to a large degree. Prior to the second Infernal Emergence, any number of stories have yet to be told. After that incident, and the new Pact, she worked very closely with her family of fiends and her long-time mentor Glasya on plans to spread her own influence further across the Hells. The fruit those plans may bear will be discovered in time, but she has been quite happy with how successful her protégé and granddaughter Philani has been thus far, and is quietly supporting her ambitions from the shadows.
Powers and Abilities
Fierna's primary powerset revolves around the use and manipulation of Hellfire. She is also incredibly charming, and frequently controls others to battle in her place in any form of combat. She is not particularly physically strong, instead relying on her personality, magic, and utter mastery over Hellfire to great effect instead.
