Dainty and small-framed for her race, Istina moves with a deliberate, rhythmic silence that borders on the ghostly. She possesses snow-pale skin and silvery-ash hair usually tucked under a dark, wool beret. Her eyes, the color of cold tea, seem to be constantly scanning for text or subtext even when she is engaged in conversation. She wears a thick, charcoal-colored coat over a pristine student uniform, and despite the chaos of her environment, she never has a speck of dust on her gold-rimmed glasses. The most striking element of her look is the heavy, iron-bound ledger she carries, which looks far too heavy for her slender arms, yet she holds it with effortless familiarity.
