"The conclusion we have come to is that this is a Pairaka. The diseases were the clue that cinched it. First of all, what is a Div you might ask. Divs strive to ruin and despoil all things created by mortals. Spawned from corrupted genies exiled to the accursed depths of Abaddon, divs harbor an ancient hatred against all mortalkind, doing all in their power not simply to destroy but also to torment all that lives. Patient and vicious, divs seek to spoil all things beautiful and joyous, dooming their victims to existences full of frustration and suffering before succumbing to lengthy, painful deaths."
"The most ancient of myths claim that divs were the aides and architects of numerous magical and forgotten mortal empires in an age of wondrous and mysterious antiquity. During this unfathomably ancient time these masters of creation served as helpful genies, allied to thankful and gracious masters. However, this bond with mortals soon frayed, as generations of the shorter-lived races ebbed and flowed like ripples in a puddle, forgetting the oaths and respect their forbearers gave divs; some began to abuse and neglect their otherworldly allies, while others merely turned away from genies to rely upon and extol the creations of mortalkind. As the contributions of geniekind were ignored and the deities celebrated the rise of their mortal creations across the worlds, many of the ancient architects rose in rebellion against mortals and the ancient deities who shepherded them. In turning from the paths of inspiration and creation, these genie rebels fell under the sway of a power of destruction known as Ahriman, who granted them not only the vicious might to avenge themselves against mortalkind, but also twisted forms marking them as paragons of depredation, havoc, and ruin. Thus did first divs come into being."
"Ever since, divs have arisen from the spirits of the most nefarious and spiteful evil genies. Rather than returning to the Elemental Planes upon their destruction, these foul genies find their way into the claws of Ahriman, a spirit of annihilation who has haunted geniekind since the earliest days of creation. Having forged a realm upon the ruined hinterlands of the foul plane of Abaddon, Ahriman uses the innate corruption of that realm along with his own immortal evil to inspire wickedness in the souls drawn to him, warping such profane spirits into div servitors of a variety of terrible forms. Indifferent to the genie race from which the soul hailed, the Lord of the Divs sees only the evil within and grants it an abhorrent shape particular to the vices that brought the genie to his domain. What emerges from Ahriman’s grip is a dreadful new fiend, an enemy of mortalkind and the deities of good, a hateful spirit given a form with which to wreak its revenge. The dark god’s touch leaves behind nothing of the individual genie that once was—only hatred, entitlement, and vengeance remain."
"Pairakas embody the corruptive nature of unbridled lust. Pairakas spend little time in their true form while on the Material Plane, choosing to cloak themselves instead in alluring forms to seduce potential victims, ruin relationships, and foment obsession. In its true form, a pairaka’s body is a foul landscape of blazing rashes, oozing pustules, and taut blisters suggestive of the corruptions it harbors, bodily and spiritually. Apparently, and not surprisingly, she never revealed her true form to you."
"Pairakas pride themselves on perversion. They love nothing more than turning lovers against one another or destroying the bonds of friendship. Pairakas feed off this slow torment and savor each broken heart or disappointment. They use lust and sexuality as their primary tools, wielding taboos and carnal appetites to sever once-friendly relationships. Pairakas also use their seduction to spread disease, charming victims into physical contact. this one seemed rather patient. Spending days observing you in her guise as she made plans. Not sure what her long term goals are, but probably not good."
