Hyacinth is a woman of average build, standing at around 5 feet 7 inches when barefoot. Quite noticably though, her entire body is made of living ice. From her cool blue eyes, to her snowy hair. She has icy skin all the way from the tip of her nose down to her frozen blue feet. She tends to sparkle with the light that refracts through her flesh.

Upon her head is a feathered headband, as well as a slender silver crown sporting a single cat's eye gemstone. Orbiting around her cranium are three separate prisms. Two of pale green and one orange. She also wears crystal lenses over her eyes to help improve her already keen vision. Around Hyacinth's neck hangs an amulet made from the claw of a large beast. And draped over her shoulders and is a handy haversack and a long green cloak that sports the image of an enormous oak on the back.

On her torso is a ghostly white cloth, covered over with a beautiful blue silk kimono-style covering. This outfit sports intricate patterns of various trees and birds. Holding it closed around her waist is a supple belt of black leather and a sheath for the adamantine dagger at her hip. Her entire ensemble is permeated by magical ice armor that strengthens and protects her existing attire.

On Hyacinth's forearms are blue leather bracers sporting star-shaped studs, and her hands are covered with a pair of heavy leather gloves. She carries a heavy mithral shield in one hand, which is covered in dozens of rods on its surface used to snag enemy weapons. The shield also sports acid-themed patterning to denote that it magically protects against such attacks. On the same hand that holds the shield are five rings. Her thumb sports a thick band of steel while the other fingers each sport a garish and gaudy ring of their own.

Lastly, on Hyacinth's feet there are a pair of blue leather boots with high soles. She normally stands alert at all times, aware of her surroundings. She moves with purpose and seems almost reluctant to relax except in the most informal of settings. Even so, she strives to act with kindness to all who deserve it. Hyacinth is almost always accompanied by her puffin familiar, Joey, who often perches on Hyacinth's shoulder or the top of her shield.
