Like all succubi, Arveni'thira possesses such infuriating symmetry and perfection in her appearance that she could only have been imagined in the most tempting and debaucherous dream. Her dark, delicious caramel skin seems devoid of marks or blemishes. Her hair is a silken swathe of fabulous platinum blonde, those enviable tresses cascading down to her lower back and parting around a pair of long, pointed sylvan ears. Her eyes are almond shaped and hypnotically attractive, with a deep amethyst-purple glow radiating brightly enough that her pupil and iris are invisible. Long lashes and dark eye-shadow accentuate her sultry gaze even further. Her nose is small and perfectly sculpted to draw attention down to her full, darkly painted lips. Her chin is slightly sharp and feminine, which when coupled with her relatively high cheek-bones, create a familiarly enticing elven face.

Her shoulders are sleek and feminine, complimenting her slender neck, though attention is often diverted further down. Her breasts are utterly divine: swells of succulent, sumptuous caramel that fill out whatever attire she wears in an almost painfully sexy fashion. Though firm, her seductive bosom nonetheless bounces and jiggles with her movements, taking a slight tear-drop shape when released. Below lay the slender expanse of her wonderfully feminine stomach, her dark skin pulled taut over very faint muscle tone and decorated with a vertical slit of a bellybutton. Her waspish waist flares out into salaciously wide hips, leading down to juicy thighs and long, tapering legs. Below the feminine dimples on her lower back rested a drool-worthy backside, each beautiful rump-cheek firm and round. The sight of her ass swaying with her tempting, sultry gait and each cheek rising and falling with each step, gifted with a slight wobble, was deliriously sexual.

A long, fleshy tail sprouted from the base of her spine, trailing downwards to the length of her legs. This fiendish appendage ended in a slightly spaded tip and swayed seductively behind her. She wore scant clothing that was purposefully designed to enhance her body and accentuate her sexual nature, with her cleavage, stomach and thighs often on display.

She spoke with a soft, mirth-filled tone, her accent difficult to place but reminiscent of the old elven empires and is best described as "British received pronunciation" or "BBC British". It was a voice perfectly crafted to tell erotic bed-time stories.

Demonic spies who used debauchery and guile to seduce their way into the beds of powerful fiends and their mortal servants, the Felfire sisters are feared not for their power but what they know. They possess secrets of such magnitude that the shadowy leaders of plane-spanning criminal empires and occult demon-worship only hunt them through distant proxies.

The Felfire sisters were not born nor spawned by the bubbling chaos of the abyss, they were created by a secretive cabal of Yugloth nobles to serve their interests in the lower planes. Succubi with hand-picked traits and such seductive eminence that even other fiends could succumb to their guile, they were to serve as spies and informants to help their mysterious master manipulate high-ranking demons and their mortal pawns.

Summoned by a hidden university of wizards and warlocks, the twins served as agents to the paranoid Dean of Magic. The Dean, in her caution, bound the twins with powerful blood-magic that supernaturally forbid them from committing violence (rough sex withstanding) so they would never be able to turn against her. With their skill and guile they helped secure The Dean's position for many years until her endurance proved lacking in a moment of passion. Freed from their servitude, but still bound by the blood-pact, the twins turned the hidden university into a den of sexual debauchery and depravity, captivating all the students in sexual bliss until they expired.

Unable to indulge in demonkind's natural urge to cause pain and suffering, the twins instead focus on using sex and debauchery as their outlet, resulting in an insatiability rare even for succubi.
