Zaryssa

Zaryssa the Ascended is the archfiend that rules over the 238th layer of Hell, the Tumorous Wastes. Unlike most other archfiends, Zaryssa did not ascend from the ranks of fiends, but was instead created by the slow, deliberate, and total corruption of a mortal woman.

Zaryssa has a special fondness for succubi and erinyes, which make up the nobility of her court. While her duties as ruler have forced her to give up seducing mortals personally, she now pursues her conquests vicariously, urging her favorite vassals to inveigle targets of her choosing. She takes a particular interest in paladins, church elders, and other so-called paragons of good, seeking to inflict on others the corruption she once suffered.

Zaryssa appears as a human woman of terrible beauty with coppery skin, batlike wings, a pair of curved horns on her brow, and a supple tail tipped with a wickedly sharp stinger.

Ascension
According to legend, the human woman that would become Zaryssa began life as a skilled magus and champion for the forces of good. A powerful adventurer, she led a desperate battle against a demonic invasion. Though her forces fought valiantly, they each fell to the fiendish hordes, one by one, until only Zaryssa remained. Her personal power and unassailable will caught the attention of the King of Hell himself, and Asmodeus ordered the horde to capture her alive and return her to his citadel in Hell.

Through centuries of grueling torture and malicious experimentation, Asmodeus and his servants managed to destroy everything the champion had been and reconstruct her little by little into what she is today: Zaryssa the Ascended, Daughter of Asmodeus and Whore Queen of the Tumorous Wastes.
