Fierna

In name, Lady Fierna ruled Phlegethos, commanding the fiery layer from her palace of rock and magma. In truth, her father, Belial, was the power behind the throne.

Description
Fierna appeared to be an incredibly attractive young woman, a lithe, statuesque, seductress of stunning physique. Tall, dark and sensual, her garments were as royally fine as they was scantily clingy, furthering her image as a being of perversion and indecency.

Giving away her infernal heritage were the small pair of horns that emerged under her hairline, and even then the fiendish features somehow managed to enhance her enchanting appearance. Her red eyes shined and smoldered like fires were dancing within them and implicit promises of pleasure could be gleaned from her gaze.

Combat
Unlike her father, Fierna never relies on a weapon, instead preferring to use her mastery of flames to manifest a flame blade and fire shield.

Cult
Being a newer archdevil in the Nine Hells, the cults that arose to venerate her struggled to settle on a specific agenda or method of operating. Their temples were often improvised whatever they could find.

Relationships
Fierna is best friends with her fellow archdevil Glasya and would often spend time at her fortress in Malbolge. In imitation of her friend, Fierna eventually started to refer to herself as an "archduchess." She was also encouraged by Glasya to start building a network of devils and cultists separate from that of her father's forces, much to his chagrin.

Out of the several dukes that serve the domain of Phlegethos, Bathym and Zapan have pledged their loyalty to Fierna over her father.

Fierna once tried to court a mighty archfey, hoping to seduce them into relinquishing their soul. Her efforts ultimately went nowhere, but a group of the lord's satyrs became infatuated with her. Desiring some form of gain from her time spent on the lord, Fierna decided to corrupt the satyr with her infernal powers and transformed them into the creatures known as forlarren.
