Ghenna stands as a remarkable sight even among the most exotic beings, her very presence commanding attention through her unique physiology. Standing at an impressive six feet four inches, her emerald-green skin gleams with an almost ethereal quality, particularly under moonlight. Her most striking feature is the arrangement of her three sapphire-blue eyes, positioned in a perfect triangle on her face - two where human eyes would be, and a third centered slightly above them. These eyes seem to pulse with an inner light when she's deep in concentration, a trait that both fascinates and unnerves those around her.

Her four arms, moving with graceful coordination, mark her as a member of the rare Quathra elven bloodline, an ancient lineage said to be blessed (or cursed, depending on who tells the tale) by a capricious god of change. Her upper pair of arms is slightly longer than the lower set, and she has developed a habit of using her upper arms for grand gestures while the lower pair handles more delicate tasks. Her fingers are long and elegant, each bearing intricate patterns of natural markings that spiral up to her wrists.

Ghenna's brown hair flows like silk down to her waist, often braided with golden threads and small crystals that chime softly when she moves. Her elongated elf ears, more prominent than those of common elves, are adorned with multiple piercings, each containing a different gemstone that she claims helps her maintain balance with the natural world. She speaks with a peculiar accent that seems to echo slightly, as if her words are being spoken twice, just milliseconds apart.

A scholar of forbidden knowledge, Ghenna has dedicated her unusually long elven life to uncovering the secrets of dimensional manipulation, believing that her unique physical form is meant to serve a greater purpose. She carries herself with the dignity of nobility, though her obsession with arcane studies has left her somewhat disconnected from normal social conventions. She has an unsettling habit of staring unblinkingly with all three eyes when something captures her interest, and often forgets that others find this intimidating.

Her typical attire consists of elaborate silk robes in deep purple and midnight blue, embroidered with golden symbols that seem to shift and change when viewed from different angles. She moves with a fluid grace that makes her appear to be floating rather than walking, though this ethereal quality contrasts sharply with her practical approach to problem-solving and her occasional bursts of frustrated profanity in ancient languages.

Despite her intimidating appearance, Ghenna possesses a dry sense of humor and an unexpected fondness for creating intricate origami sculptures, often using all four hands simultaneously to craft complex designs. She harbors a deep-seated fear that her unique form is not a blessing but a sign of some cosmic mistake, driving her to seek validation through her arcane research. This insecurity manifests in her tendency to overcompensate with displays of magical prowess and scholarly knowledge, though she tries to mask it behind a facade of confidence and sophistication.

A collection of small scars on her lower left hand serves as a reminder of failed experiments, though she views them as badges of progress rather than marks of failure. She has developed an extensive personal code of ethics regarding the use of magic, though these rules often seem arbitrary to others and frequently conflict with conventional morality. Her pursuit of knowledge has led her to make both powerful allies and dangerous enemies, though she tends to view such relationships as temporary conditions in her eternal quest for understanding.
